Educational Technology: Concepts, Tools, and Impact on Learning
UNIT-I Concept of Educational Technology
Meaning, Definitions & Scope of Educational Technology
The word “Technology” is derived from the two Greek words Technic and Logia. “Technic” means “art or skill.” “Logia” means “Science or Study”. So the simplest meaning of Technology is “Science of study of an art or skill.”
Definitions of Technology
- “Technology is Knowledge organized for Production.” – Sachs.I
- “Technology is the application of scientific knowledge to a practical purpose.” – Page.T
- “Technology is the set of instruments and skills which are used to satisfy the needs of the community”
Meaning of Education
The word “Education” is derived from the Latin word “Educatum”, which means “To bring out.” In this sense, the meaning of Education is to bring out the better qualities of the individual.
According to Ross, the word “Education” is derived from the Latin word “Educare” which means “to bring up” or “to raise”. It means that education is that process which brings up or rears the individual in the right way.
Meaning of Educational Technology
There are three views regarding the meaning of educational technology.
The first view, which may be called Educational Technology 1 (ET 1), refers to the application of physical sciences and engineering technology to provide mechanical instruments or “hardware” which can be used for instructional purposes. This is the view of James O. Finn and others (1960).
E.g. Tape-recorders (including language laboratory), television, teaching machines and computer-based teaching
The second view, which we may call Educational Technology 2 (ET 2), refers to the application of scientific principles or “software approach” to instruction. This is the view of Skinner, Gagne and others.
The third and the modern view of Educational Technology 3 (ET 3) as described by Davis and Hartley (1972), incorporates both ET 1 and ET 2 through the application of a “system approach” to education and training
“Educational technology may be defined as the application of the laws as well as recent discoveries of science and technology to the process of education.” – S.S. Kulkarni
Characteristics of Educational Technology
- ET has contributed in developing various methods e.g. Microteaching method, Interaction analysis, Audio Visual Aids and Programmed learning method.
- In the field of ET, Psychology, Science and technology, system, art, AV aids and machines are used.
- It is based on the application of the scientific knowledge.
- It is helpful in making the teaching process objective, easy, clear, interesting and scientific.
- It is a continuous dynamic technology.
- It is an important medium of communication.
Scope of Educational Technology
Educational technology is a process-oriented technique. Educational technology is not limited to teaching and learning process and theories still teaching-learning process is influenced much more by educational technology. Theories have been shifted from learning to teaching only due to educational technology.
If the educational technology is limited to audio-visual aids, mechanical and electronic gadgets the scope of educational technology becomes limited, but educational technology is not limited to all these things rather, it pervades all over. Educational technology should go into:
- At home.
- Managed by external assistance.
- Rigorous task analysis.
- Specification of direct behaviour.
- Determination of pre-requisites and the gradual direct behaviour.
- Clear specification of the problem.
- Hindrance in solving problems.
- Management and organization of man, material, resources.
- Availability of a few media as for example films, television, radio etc.
- Developing software technology.
Significance of Educational Technology
Access to variety of learning resources: In the era of technology. ET aids plenty of resources to enhance the teaching skills and learning ability. With the help of ET now it is easy to provide audio visual education. The learning resources are being widens and widen. Now with this vivid and vast technique as part of the ET curriculum, learners are encouraged to regard computers as tools to be used in all aspects of their studies. In particular, they need to make use of the new multimedia technologies to communicate ideas, describe projects and order information in their work.
Immediacy to information. EJ has provided immediacy to education. Now in the year of computers and web networks the pace of imparting knowledge is very fast and one can be educated anywhere at any time. New IT has often been introduced into well-established patterns of working and living without radically altering them. For example, the traditional office, with secretaries working at keyboards and have replaced typewriters. notes being written on paper and manually exchanged, has remained remarkably stable, even if personal computers
Any time learning: Now in the year of computers and web networks the pace of imparting knowledge is very irrespective of being in India or in US because of the boom in ET. and one can be educated. One can study whenever he wills irrespective of whether it is day or night and fast
Collaborative learning: Now ET has made it easy to study as well as teach in groups or in clusters. With online we can be unite together to do the desired task. Efficient postal systems, the telephone (fixed and mobile), and various recording and playback systems based on computer technology all have a part to play in educational broadcasting in the new millennium. The Internet and its Web sites are now familiar to many children in developed countries and among educational elites elsewhere, but it remains of little significance to very many more, who lack the most basic means for subsistence.
Multimedia approach to education: Audio-Visual Education, planning, preparation and use of devices and materials that involve sight, sound or both, for educational purposes. Among the devices used are still and motion pictures, filmstrips, television, transparencies, audiotapes, records, teaching machines, computers, and videodiscs. The growth of audio-visual education has reflected developments in both technology and learning theory. Studies in the psychology of learning suggest that the use of audio-visuals in education has several advantages. All learning is based on perception, the process by which the senses gain information from the environment. The higher processes of memory and concept formation cannot occur without prior perception. People can attend to only a limited amount of information at a time; their selection and perception of information is influenced by past experiences. Researchers have found that, other conditions being equal, more information is taken in if it is received simultaneously in two modalities (vision and hearing, for example) rather than in a single modality. Furthermore, learning is enhanced when material is organized and that organization is evident to the student. These findings suggest the value of audio-visuals in the educational process. They can facilitate perception of the most important features, can be carefully organized, and can require the student to use more than one modality.
Authentic and up to date information: The information and data which are available on the net is purely correct and up to date. Internet, a collection of computer networks that operate to common standards and enable the computers and the programs they run to communicate directly provides true and correct information.
Online library: Internets support thousands of different kinds of operational and experimental services one of which is online library. We can get plenty of data on this online library. As part of the T curriculum, learners are encouraged to regard computers as tools to be used in all aspects of their studies in particular, they need to make use of the new multimedia technologies to communicate ideas, describe projects, and order information in their work. This requires them to select the medium best suited to conveying their message, to structure information in a hierarchical manner, and to link together information to produce a multidimensional document.
Distance learning: Distance Learning, method of learning at distance rather than in a classroom. Late 20th- century communications technologies, in their most recent phases multimedia and interactive, open up new possibilities, both individual and institutional, for an unprecedented expansion of home-based learning, much of it part-time. The term distance learning was coined within the context of a continuing communications revolution, largely replacing a hitherto confusing mixed nomenclature-home study, independent study, external study, and, most common, though restricted in pedagogic means, correspondence study. The convergence of increased demand for access to educational facilities and innovative communications technology has been increasingly exploited in face of criticisms that distance learning is an inadequate substitute for learning alongside others in formal institutions. A powerful incentive has been reduced costs per student. At the same time, students studying at home themselves save on travel time and other costs. Whatever the reasoning, distance learning widens access for students unable for whatever reason (course availability, geographical remoteness, family circumstances, individual disability) to study alongside others. At the same time, it appeals to students who prefer learning at home. In addition it appeals to organizers of professional and business education, providing an incentive to rethink the most effective way of communicating vital information.
Better accesses to children with disabilities: Information technology has brought drastic changes in the life of disabled children. El provides various software and technique to educate these poor peoples. Unless provided early with special training, people profoundly deaf from birth are incapable of learning to speak. Deafness from birth causes severe sensory deprivation, which can seriously affect a person’s intellectual capacity or ability to learn. A child who sustains a hearing loss early in life may lack the language stimulation experienced by children who can hear. The critical period for neurological plasticity is up to age seven. Failure of acoustic sensory input during this period results in failure of formation of synaptic connections and, possibly, an irremediable situation for the child. A delay in learning language may cause a deaf child’s academic progress to be slower than that of hearing children. The academic lag tends to be cumulative, so that a deaf adolescent may be four or more academic years behind his or her hearing peers. Deaf children who receive early language stimulation through sign language, however, generally achieve academically alongside their hearing peers.
Technology of Education and Technology in Education
The terms “Technology of Education” and “Technology in Education” are often used in discussions about educational methods and tools. Though they sound similar, they represent different concepts:
1. Technology of Education
This refers to the systematic application of educational techniques, strategies, and frameworks aimed at improving the teaching and learning process. It deals with theory and design of instructional materials, methods, and evaluation techniques. In this context, technology doesn’t necessarily mean digital tools or devices but rather refers to structured approaches to teaching and learning.
- Focus: Pedagogical techniques and instructional design
- Examples: Learning theories (constructivism, behaviorism), instructional design models (ADDIE), assessment strategies, and curriculum development
- Application: Organizing, planning, and delivering education using scientifically-backed methods.
2. Technology in Education
This term refers to the use of digital tools and devices (hardware, software, online resources) to facilitate and enhance education. It focuses on the practical integration of technology into classrooms and educational settings.
- Focus: Practical application of technological tools
- Examples: Learning management systems (LMS), interactive whiteboards, educational apps, AI-based learning platforms, online courses
- Application: Incorporating digital tools to improve access, engagement, and effectiveness in learning.
Key Differences
- Technology of Education is more focused on educational theory and the development of instructional methods.
- Technology in Education is about applying digital tools and resources to facilitate learning.
Historical development of Educational Technology
The history of Educational Technology can be traced back to four ages, the Stone and Rock age, the Book print and Chalkboard age, the Mass Communication age and Information Communication age.
Stone Age Period
You must have been told the history of the early men at the elementary school. It is the same early men that we are referring to here. You would recall that he was reputed to have lived inside the cave. He was described as a wanderer and that he lived a “crude” life. History had it that he ate his food raw until he was able to discover fire. As a wanderer the early men on a very good day must have covered a very long distance. Covering a long distance implies that he must have encountered series and variety of experiences before hiding his head inside a cave. Though as a stack illiterate, he was able to make some drawings on the surfaces of rocks and other flat objects. Indeed, it could be inferred that some of the drawing would have been generated from his familiarity with his immediate environment. Drawing technology or the art of drawing could then be associated to the early men. Writing technology too was another associated invention credited to the early men. Therefore, if writing and drawing are regarded as essential features of educational technology, then, the early men deserved recognition as the progenitor of the discipline.
The use of stones, pebbles, slates or slabs, counting sticks and bottle caps as is done in most of primary schools are regarded as the replica of the early man’s period. During this period, education was elitist and Aristotelian in could afford to hire the services of the teachers to teach their sons and daughters in their homes. Typically of this nature. Education then was reservation for the rich/elites. It was the period when only few individuals in the society period was the activity of the sophists. The sophists were itinerant teachers who moved from one place to another teaching and collecting money for the service being rendered. At that stage, there was monopoly of knowledge by the “professional” teachers.
Characteristics of Stone and Rock Age
- Education of the pupils was at different homes as there was no classroom
- There was close relationship between the pupils and the teacher
- Education is elitist in nature. This is where the rich of the society employed a teacher to teach their children in their homes.
The Age of Book and Chalkboard
In 1456, Johann Guttenberg developed the printing machine with which he was reputed to have printed the first Bible. With this invention, the art of printing spread widely and other books were produced. With information explosion, there was wider spread of awareness and knowledge acquisition. Many people were interested in learning thus it became obvious that “one and one” teacher-pupil interaction as was the situation prior to the invention of the printing machine was no longer workable. This paved way for the assemblage of students at a
place for the teacher to attend to simultaneously. The resultant effect of this group communication was the invention of the chalkboard which was popularly known by then as blackboard. The board served as a central point of focus for all the students. It also provided the teacher a place to write down important points, diagrams and symbols. Now, we have different kinds of board in circulation. Mention could be made of wall boards, portable boards, easel board, and magnetic board etc.
Characteristics of Block Print and Chalkboard Age
- More pupils had access to education
- Classrooms were used for instruction has against different homes
- Care was used as a means of facilitating better teaching-learning among the pupils
Components of Educational Technology & their significance; Hardware, Software, & Systems Analysis
Educational Technology encompasses a range of tools, techniques, and strategies used to enhance teaching and learning processes. Its components can be broadly categorized into hardware, software, and systems analysis, each playing a critical role in the development and delivery of education. Here’s a breakdown of these components and
their significance:
1. Hardware
Hardware refers to the physical devices and equipment used in educational settings to facilitate learning. These devices enable both instructors and students to access, create, and share educational materials effectively.
- Examples:
a) Computers, tablets, and laptops: For accessing educational content, creating projects, and conducting research.
b) Interactive whiteboards: To enhance classroom engagement through interactive lessons.
c) Projectors: For displaying multimedia presentations, videos, or other learning materials.
d) Virtual reality (VR) headsets: For immersive learning experiences, such as virtual field trips or simulations.
e) Laboratory equipment: In science and technical education for practical experiments.

- Examples:
a) Learning Management Systems (LMS): Platforms like Moodle, Blackboard, and Google Classroom manage course materials, assignments, assessments, and communication.
b) Educational Apps: Tools like Duolingo, Kahoot!, and Mathway offer specialized learning
Content creation tools: Software like Microsoft Office, Google Docs, or multimedia tools (video/audio editing) help teachers and students create and share educational content.
c) Simulation software: Used in areas like science, engineering, or medical education for virtual labs
or experiments.
Significance:
Software makes learning more organized and accessible. It allows for differentiated instruction, catering to diverse learning needs, and automates administrative tasks like grading and attendance tracking. Additionally, it can enhance learning through gamification, interactivity, and personalized learning paths.
3. Systems Analysis
Systems analysis refers to the process of studying and understanding the various components of an educational system (such as learners, instructors, content, and delivery mechanisms) to optimize the effectiveness of educational technology. It involves examining how different components interact and identifying ways to improve learning outcomes and institutional efficiency.
- Examples:
a) Needs assessment: Determining the specific educational requirements of learners and teachers. software.
b) Resource allocation: Deciding how to best allocate technological resources, such as hardware and software.
c) Evaluation metrics Defining key performance indicators (KPIs) and assessment tools to measure the success of technological interventions.
d) Designing instructional strategies: Aligning technology use with instructional goals, learner needs, and institutional constraints.
Significance:
Systems analysis helps in the careful design and implementation of educational technology strategies. By evaluating and optimizing all components of the system (learners, resources, content delivery), it ensures that the integration of technology leads to improved learning outcomes. It also identifies potential gaps or inefficiencies that can be addressed to enhance educational effectiveness.
Summary of Significance:
- Hardware provides the physical infrastructure that supports digital learning.
- Software offers platforms and applications that enable, manage, and enhance the learning experience.
- Systems analysis ensures that technology integration is carefully planned and effectively implemented, with an emphasis on improving learning outcomes.
Together, these components make educational technology a comprehensive field that focuses on improving education through well-designed tools and processes.
Types of Educational Technology
- Synchronous Learning: Synchronous learning refers to educational activities that happen in real-time, where teachers and students interact simultaneously. Technologies like live video conferencing tools, real- time chat platforms, and interactive webinars are central to this approach. The benefit of synchronous learning is the immediate feedback and interaction it offers, closely mimicking traditional classroom dynamics. However, it requires participants to be available at the same time, which can be challenging across different time zones or schedules.
- Asynchronous Learnings: Asynchronous learning, in contrast, allows learners to access and engage with course materials on their own schedule. This method often utilises pre-recorded video lectures, digital assignments, and online discussion forums. It offers flexibility, enabling learners to study at their own pace and revisit materials as needed. The challenge here lies in maintaining motivation and engagement without the real-time interaction of a traditional classroom.
- Collaborative Learning: Collaborative learning emphasises the power of learning with others. It leverages technology like shared digital workspaces, social media platforms, and collaborative software tools to enable group projects and peer-to-peer interactions. This approach fosters teamwork and communication skills, offering a more dynamic and interactive learning experience. The key challenge is ensuring effective collaboration and communication among all participants.
- Linear Learning – Computer-Based Learning: Linear learning, especially in the form of computer-based learning, involves a structured, step-by-step instructional approach. Educational software and interactive modules guide learners through a predetermined sequence of topics or skills. This method is particularly effective for foundational subjects
and skill-based training, providing a clear and focused learning path. However, it may lack the flexibility and adaptability of other forms of learning.
Instructional Technology, Teaching Technology, Behavior Technology, Instructional Design
The terms Instructional Technology, Teaching Technology, Behavior Technology, and Instructional Design are integral components in the field of educational technology Each one represents a specific aspect of how technology and methods are applied to improve teaching, learning, and behavior management. Here’s a detailed explanation of each term:
1. Instructional Technology
Instructional Technology refers to the theory and practice of using technological tools and methods to support the design, development, delivery, and assessment of educational experiences. It encompasses both hardware (physical devices) and software (digital tools), with a focus on improving the efficiency and effectiveness of the instructional
process.
- Examples:
a) Learning Management Systems (LMS) like Moodle or Blackboard
b) Multimedia tools (PowerPoint, Prezi, video editing software) Interactive learning platforms (Khan Academy, Coursera)
Significance:
Instructional technology helps create a more engaging, interactive, and accessible learning environment. It supports the individualization of instruction, providing resources and tools tailored to the needs of diverse learners. By Integrating technology, educators can offer more dynamic content, varied assessment methods, and real-time feedback.
2. Teaching Technology
Teaching Technology focuses on the specific tools, techniques, and strategies used by educators to facilitate teaching. While closely related to instructional technology, teaching technology is more concerned with the methods and processes used by the teacher to enhance the delivery of instruction. It emphasizes how teachers use various tools and methods to improve their teaching practices.
- Examples:
a) Flipped classroom models using video lessons
b) Adaptive learning techniques that modify instruction based on student performance
c) Teacher-created digital content like blogs, podcasts, and interactive quizzes
d) Use of clickers or audience response systems in lectures
Significance:
Teaching technology enhances the way educators deliver content. It allows teachers to engage students through innovative strategies, manage diverse learning needs, and promote active learning. It is especially valuable in improving teacher-student interaction and assessment.
3. Behavior Technology
Behavior Technology applies principles from behavioral psychology to influence and shape student behavior in educational settings. It involves using systematic techniques to modify behavior often focusing on reinforcement and feedback strategies to encourage desired behaviors and reduce undesirable ones.
This concept is rooted in behaviorism, which emphasizes observable and measurable aspects of behavior, particularly how external stimuli affect learning.
- Examples:
a) Positive reinforcement: Reward systems, praise, or tokens for good behavior or academic performance
b) Behavioral interventions: Techniques like time-outs, reinforcement schedules, or self-monitoring strategies
c) Classroom management tools: Apps or systems that track and reward student behavior (e.g., ClassDojo)
Significance:
Behavior technology is important in maintaining discipline, promoting positive behavior, and creating a conducive learning environment. It is particularly useful in special education, early childhood education, and for managing classrooms effectively. By focusing on behavioral outcomes, educators can help students develop better self- regulation and motivation.
4. Instructional Design
Instructional Design (ID) is the systematic process of developing educational experiences and materials to achieve specific learning goals. It is based on learning theories and principles and involves analyzing learners’ needs, defining learning objectives, designing instructional strategies, and evaluating outcomes.
It often follows structured models like ADDIE (Analyze, Design, Develop, Implement, Evaluate) or Gagné’s Nine Events of Instruction to ensure that educational content is well-organized and effective.
- Examples:
a) Designing a curriculum or e-learning course using backward design (starting with learning outcomes)
b) Creating instructional modules for online platforms like Udemy
c) Developing learning activities, assessments, and interactive simulations for training programs
d) Using learning theories like constructivism, cognitivism, or behaviorism to inform course structure
Significance:
Instructional design ensures that educational materials and experiences are effective, learner-centered, and aligned with educational objectives. It plays a crucial role in both traditional and online education, ensuring that the content is designed to maximize learning outcomes and cater to different learning styles. By carefully planning and designing instructional experiences, instructional designers help ensure that learning is effective, efficient, and engaging.
Unit 2
Concept & Principles of Teaching
Concept of Teaching
UNIT-II Technology of Teaching
The concept of teaching will be more clear through the definition of teaching given by different scholars-
According to H.C Marrison (1943), ” Teaching is an intimate contact between a more mature personality and a less mature, one which is designed to further the education of the latter”
According to John Broubacher (1939), “Teaching is an arrangement and manipulation of situation in which there are gaps and obstructions which an individual with seeking to overcome and from which he will learn in course of doing so”
According to B.O Smith (1960), ” Teaching is a system of action intended to produce learning
According to Burton (1963), “Teaching is the stimulation, guidance, direction and encouragement of learning”
Characteristics/ Nature of Teaching
- Teaching is a complex social phenomenon. It is greatly influenced by social factors. The social and human factors are dynamic, not static and therefore teaching is not a fundamental concept.
- Teaching is both art as well as signs. Art is called for exercises of talent and creativity signs because it is a collection of techniques, procedures and skills that can be systematically studied and described and improved.
- Teaching is a professional activity involving the teacher and the students and results in the development of the student.
- Teaching is what a teacher does with his student for focusing the letter to learn something.
- Teaching is a system of actions which are varied in form and are related to content and pupil’s behaviour in context with the prevailing physical and social conditions.
- Teaching can be observed, analysed and assessed through teacher behaviour, pupil-teacher interaction and the changes brought in the behaviour of the pupils.
- Teaching is highly dominated by communication skills.
- Teaching is an interactive process carried out for the attainment of some specific progress objectives.
- Teaching may have various forms like formal and informal teaching, showing or doing descriptive or remedial, formational or informational.
- Teaching is a specialized task and may be taken as a set of competent skills for the realization of a specified set of instructional objectives.
Principles of Teaching
General principles of teaching
- Principle of definiteness of goals or objectives: Teaching should start with defining aim and objective. The teacher and students must be clear about the goals of teaching-learning. It helps them to be on the track. When the goals and objectives of the lesson are determined properly it will help the teacher to plan, execute and evaluate the phase of the teaching-learning process.
- Principle of Planning: Planning in teaching is a very important step, teachers must plan properly before coming to actual classroom teaching. The successful teaching-learning process highly depends on teachers’ planning and execution in the class. The planning includes a lesson plan, Teaching aids, Strategy and Methods of teaching.
- Principle of flexibility and elasticity: The teaching strategy must be flexible. It needs to be changed according to the classroom situations and the needs of students. Teachers should be imaginative and resourceful people so that they can adapt strategies according to the needs of the classroom environment.
- Principle of utilization past experience: In effective teaching, the teacher must start a lesson with questions to know about the student’s previous knowledge. Prior knowledge could reduce the cognitive load leading to better learning engagement.
- Principle of child centeredness: The modern education system is child centeredness. According the National Curriculum Framework (NCF), the students are the active participant and the teacher are the facilitator. So the teaching should be according to the child’s needs, abilities and interests and teaching should be activity-based so that students can be learned with the active participants.
- Principle of making provision for individual differences: As we know every child is different from each other. The teacher should be kept in mind Individual differences while teaching and he should teach according to the children’s abilities and interests.
- Principle of linking with actual life: According to the NCF-2005 the learning should go beyond the four walls of the school. Teaching should be linked with real-life experiences of everyday life. It not only motivates students but also makes them easy to learn a lesson. In teaching, lesson teacher should give an appropriate examples with the students day to day life activities
- Principle of correlating with other subjects: The correlating of one subject with another subject is very important in order to create interest in the subject. In effective teaching, the teacher gives correlates one subject with another to the overall development of the students.
- Principle of effective strategies and instructional materials: Effective strategies in teaching are very important. The teacher should adopt effective teaching methods so that students can gain maximum knowledge and the teaching aids and other instructional materials should be used effectively.
- Principle of active participation and involvement: In modern-day education, teaching and learning must be child centeredness so that children can actively participate in learning. The teacher should use the activity- based teaching method so that the maximum number of students can be involved and active participants in the teaching-learning process.
- Principle of conducive environment and proper control: The teacher should create such a conducive environment so that it becomes a motivating factor for learning. There must be proper arrangement of light, furniture and other needful resources. The teacher should maintain proper order and discipline by being sympathetic but at the same time, he must be firm.
Phases of Teaching; Pre-active, Interactive, post active Phases of Teaching-Levels of Teaching: Memory Level, Understanding Level, & Reflective Level
- Models of Teaching: Concept and definition of Models of Teaching, Types of Teaching Models; Information Processing Models, Behavioural Models, Social Models, Personal Models, & Bloom’s mastery learning
Models of Teaching
Many educationists have suggested different classifications of teaching models. Israel Scheffler has described three major philosophical teaching models. E.E. Haddan explained four teacher educational models. There are several other classifications also. But the following are three classifications
Types Of Teaching Models
A. Historical Teaching Model
- Socratic Teaching
- Classical Humanistic Model
- Personal Development Model
B. Psychological Teaching Model
- Basic Teaching Model
- Interaction Teaching Model
- School learning Teaching Model
- Computer Based Teaching Model
C. Modern Teaching Model
- Information Processing Teaching Model
- Personal Teaching Model
- Social Interaction Teaching Model
- Historical Teaching Model
- Behavior Modification Teaching Model
Historical Teaching Model
- Socratic Teaching Model: The Socratic teaching model involves asking thought-provoking questions to encourage critical thinking and stimulate deep insights. This method is based on the belief that knowledge is within individuals and can be drawn out through dialogue and inquiry. Socratic teaching aims to facilitate the learning process by challenging assumptions, exploring new ideas, and encouraging students to think for themselves.
- Classical Humanistic Model: The Classical Humanistic teaching model emphasizes the importance of student-centred learning and recognizes the role of the teacher as a facilitator and guide. This model encourages the development of a positive and supportive classroom environment that fosters students’ intrinsic motivation, creativity, and self-expression. It also emphasizes the importance of personalized learning experiences, individualized feedback, and opportunities for self-reflection and self-evaluation.
- Personal Development Model: The Personal Development teaching model focuses on helping students develop self-awareness, self-esteem, and interpersonal skills. It emphasizes the importance of personal growth and the role of education in fostering students’ personal and social development. This model encourages students to explore their strengths, interests, and values and provides opportunities for self- reflection, goal-setting, and feedback. The Personal Development teaching model aims to prepare students for success not only academically but also in their personal and professional lives.
Psychological Teaching Model
- The Basic Teaching Model: The Basic Teaching Model is a simple and widely used approach to teaching that consists of four stages:
(1) Preparation: In the preparation stage, the teacher plans and organizes the lesson and sets learning objectives.
(2) Presentation: In the presentation stage, the teacher introduces new concepts or information to the students.
(3) Practice: In the practice stage, students engage in activities or exercises to apply and reinforce their learning.
(4) Assessment: In the assessment stage, the teacher evaluates the student’s understanding and mastery of the
lesson objectives.
The Basic Teaching Model is flexible and adaptable to different teaching contexts and subject areas.
2. The Interaction Teaching Model: The Interaction Teaching Model emphasizes the importance of active student participation and interaction in the learning process. It is based on the idea that learning is a social activity that involves collaboration, discussion, and feedback. In this model, the teacher acts as a facilitator, guiding and supporting students as they engage in group activities, discussions, and problem-solving tasks. The Interaction Teaching Model encourages students to develop their communication and interpersonal skills, as well as their critical thinking and problem-solving abilities.
3. The School Learning Model: The School Learning Model is a comprehensive approach to teaching and learning that takes into account the multiple factors that influence students’ academic and personal development. This model recognizes the importance of creating a positive and supportive learning environment, fostering students’ motivation and engagement, and providing personalized and differentiated instruction. The School Learning Model also emphasizes the importance of collaboration and communication between teachers, students, and families, as well as the use of data and evidence-based practices to inform instructional decisions and improve student outcomes.
4. The Computer-Based Teaching Model: The Computer-Based Teaching Model is an approach to teaching that incorporates technology, such as computers, software, and multimedia resources, into the learning process. This model emphasizes the use of interactive and engaging digital content to support student learning and achievement. The Computer-Based Teaching Model can provide personalized and self-paced instruction, immediate feedback and assessment, and opportunities for student collaboration and communication. This model also allows for the integration of diverse media formats, such as video, audio, and interactive simulations, to enhance student engagement and motivation.
Modern Teaching Models :
1. The Information Processing Teaching Model: The Information Processing Teaching Model is a cognitive approach to teaching and learning that focuses on how students acquire, store, and retrieve information.
This model emphasizes the importance of providing students with explicit instruction on how to process
and organize information, and how to use strategies such as rehearsal, elaboration, and mnemonics to enhance memory and learning. The Information Processing Teaching Model also encourages the development of metacognitive skills, such as self-regulation, reflection, and self-monitoring, to help students become more effective and independent learners.
2. The Personal Teaching Model: The Personal Teaching Model is a student-centred approach to teaching that emphasizes the development of student’s personal and interpersonal skills, such as self-awareness, self- regulation, empathy, and communication. This model recognizes the importance of creating a positive and supportive learning environment that fosters students’ social and emotional growth, as well as their and collaboration. achievement. The Personal Teaching Model also encourages the use of varied and interactive instructional strategies that engage students in the learning process and promote their active participation
3. The Social Interaction Teaching Model: The Social Interaction Teaching Model is a student-centred approach to teaching that emphasizes the importance of social interaction and communication in the learning process. This model recognizes that learning is a social activity that involves collaboration, problems. discussion, and feedback. In this model, the teacher creates a positive and supportive learning environment that encourages students to share their ideas, engage in group activities, and work together to solve
4. The Behavior Modification Teaching Model: The Behavior Modification Teaching Model is an approach to teaching that focuses on changing students’ behaviour through reinforcement and consequences. This model emphasizes the use of positive reinforcement, such as praise or rewards, to encourage desirable behaviour and negative consequences, such as loss of privileges or time-out, to discourage undesirable behaviour. The Behavior Modification Teaching Model also involves setting clear and specific goals for student behaviour, monitoring progress, and adjusting strategies as needed.
In conclusion, these models are shaped by the methods used in the classroom to create an ideal learning environment and enhance teachers’ teaching skills and effectiveness. They contribute to improving students’ academic performance. These models remain useful in modifying and enhancing teaching approaches, thereby students. In essence, they promote positive teacher-student interaction. helping to meet the diverse needs of today’s students and facilitating better communication between teachers and students. In essence, they promote positive teacher-student interaction.
Modification of Teaching Behaviour: Micro Teaching,
Flounder’s interaction Analysis:
Micro Teaching:
Micro teaching was first adopted by Dwight W. Allen and his co-workers at Stanford University, USA, while in India the first attempt was made in 1974 to spread micro teaching. Micro Teaching is a technique in which a teacher is trained for learning teaching skills. In this technique, the teacher is put in a real-life situation wherein thell skills are developed and they tend to get a deeper understanding of the subject matter.
Definition of Micro Teaching:
“Micro Teaching is a scaled-down teaching encounter in class size and time” D.W. Allen
“Microteaching as a training technique, which requires student teachers to teach a single concept using specified teaching skill to a smaller number of pupils in a short duration of time.” -B.K. Passi
Micro teaching is a process wherein teacher training is done and faculty development techniques are developed where the teacher reviews a recording of the teaching session, to get substantial feedback from peers and/or students about what has been followed properly and what further improvements can be adopted in the teaching techniques. The nature of teaching is also applicable to it.
Micro Teaching literally means teaching in miniature, wherein the teacher is asked to deal with fewer students and lesser assignments. Micro teaching can include various methods of teaching as well which can be helpful for improving learners characteristics in for the evaluation system.
Objectives of Micro Teaching:
Micro teaching is a very constructive method used in enhancing the teaching skills of a teacher and to some extent the pupils as well. The agenda of micro teaching can be better understood from below mentioned points.
* It concentrates on specific teaching behaviors and provides opportunities for practicing teaching under controlled
* Through micro-teaching the behavior of the teacher as well as the pupil is modified and the teaching- learning process becomes more effective through skill training.
* To make the teacher ready to take up real-time classes with confidence.
* It helps in developing the knowledge, skills, and capabilities of the teachers.
* Through this teachers get immediate feedback on their performances which can be worked upon for further improvements.
* As this is a sort of test for the teachers it will not put students at risk if the teacher fails to perform well.
Process or Steps of Micro Teaching:
In the actual process the teacher was asked to prepare a short lesson (ideally for 20 minutes) for a handful of students, who were not necessarily his/her students in real life. This session was simultaneously recorded and later viewed by the teacher and the students and constructive feedback was noted on their views on the session delivered. There are various levels of teaching involved. The various factors affecting teaching are also applicable here.
The teacher got feedback from the students as well as colleagues who judged the teaching process from the microscopic view.
The ideal micro teaching cycle is of 36 minutes, wherein teaching takes about 6 minutes, feedback takes 6 minutes, re-plan takes 12 minutes, re-teach takes 12 minutes and re-feedback takes 6 minutes.
Flounder’s interaction Analysis:
Simulation:
Simulation teaching is a method of instruction that involves creating a realistic environment or scenario that mimics real-world situations. This allows students to practice and develop their skills in a safe and controlled setting,without the risk of real-world consequences.
Simulation teaching is commonly used in fields such as healthcare, aviation, and military training. For example, in healthcare, simulation teaching can involve using lifelike mannequins or virtual reality technology to simulate medical emergencies and procedures.
Simulation teaching typically follows a structured process, which includes the following steps:
1. Pre-briefing: The instructor provides an overview of the scenario and outlines the learning objectives.
2. Scenario: The simulation is carried out, with the students participating in the role-play.
3. Debriefing: After the simulation, the instructor facilitates a discussion with the students to reflect on their experiences, identify areas for improvement, and reinforce key learning points.
Simulation teaching can be highly effective in helping students develop practical skills and apply theoretical knowledge in a realistic context. It can also be a useful tool for assessing student performance and identifying areas
Some key features of Simulation include:
1. Realistic scenarios: Simulation teaching involves creating realistic scenarios that mimic real-world situations. This allows students to apply their knowledge and skills in a safe and controlled environment, without the risk of real-world consequences.
2. Active participation: Simulation teaching encourages active participation by students. They take on roles and perform tasks within the simulated environment, which helps to increase engagement and retention.
3. Feedback: Simulation teaching provides immediate feedback to students. Instructors can observe and evaluate student performance during the simulation, and provide feedback to help them improve.
4. Repetition: Simulation teaching allows for repeated practice of skills and tasks. This can help students to develop proficiency and confidence in their abilities.
Unit 3
UNIT-III Concept of Communication process
Meaning, nature, and process of communication process :
Component of Communication process.
Communication is a process of exchanging verbal and non verbal messages. It is a continuous process. Pre-requisite of communication is a message. This message must be conveyed through some medium to the recipient. It is essential that this message must be understood by the recipient in same terms as intended by the sender. He must respond within a time frame. Thus, communication is a two way process and is incomplete without a feedback from the recipient to the sender on how well the message is understood by him.
The main components of communication process are as follows:
1. Context – Communication is affected by the context in which it takes place. This context may be physical, social, chronological or cultural. Every communication proceeds with context. The sender chooses the message to communicate within a context.
2. Sender/Encoder – Sender/Encoder is a person who sends the message. A sender makes use of symbols (words or graphic or visual aids) to convey the message and produce the required response. For instance – a training manager conducting training for new batch of employees.
Sencer may be an individual or a group or an organization. The views, background, approach, skills, competencies, and knowledge of the sender have a great impact on the message. The verbal and non verbal symbols chosen are essential in ascertaining interpretation of the message by the recipient in the same terms as intended by the sender.
3. Message Message is a key idea that the sender wants to communicate. It is a sign that elicits the response of recipient. Communication process begins with deciding about the message to be conveyed. It must be ensured that the main objective of the message is clear.
4. Medium – Medium is a means used to exchange/transmit the message. The sender must choose an appropriate medium for transmitting the message else the message might not be conveyed to the desired recipients.
The choice of appropriate medium of communication is essential for making the message effective and correctly interpreted by the recipient. This choice of communication medium varies depending upon the features of communication.
For instance – Written medium is chosen when a message has to be conveyed to a small group of people, while an oral medium is chosen when spontaneous feedback is required from the recipient as misunderstandings are cleared then and there.
5. Recipient/Decoder – Recipient/Decoder is a person for whom the message is intended/aimed/targeted. The degree to which the decoder understands the message is dependent upon various factors such as knowledge of recipient, their responsiveness to the message, and the reliance of encoder on decoder.
6. Feedback – Feedback is the main component of communication process as it permits the sender to analyze the efficacy of the message. It helps the sender in confirming the correct interpretation of message by the decoder. Feedback may be verbal (through words) or non-verbal (in form of smiles, sighs, etc.). It may take written form also in form of memos, reports, etc.
Types of classroom Communication :
* Verbal communication:
Communication occurs through verbal, verbal or written communication that conveys or conveys a message to others is called oral communication. Verbal communication is the use of language to convey information verbally or in sign language.Verbal communication is important because it works well. It can be helpful to support verbal Non- verbal communication Any non-verbal communication, spoken words, conversation and written language is called.
* Non-verbal communication:
It occurs with signs, symbols, colors, touches, body or facial features. Insignificant communication is using body language, body language and facial expressions to convey information to others. It can be used both intentionally and deliberately. For example, you may have a smile on your face when you hear an idea or a piece of interesting or exciting information. Open communication is helpful when you are trying to understand the thoughts and feelings of others.
Barriers of classroom Communication:
1. Verbalism:
Excessive verbalism can no longer be condoned, particularly in today’s world of communication, which offers much more effective substitutes from other avenues of expression. Such verbalism is a limiting barrier to effective classroom communication
2. Anxiety: One of the significant emotional causes of communication barriers is a student’s anxiety. Students who are anxious and unsure are less likely to speak up in class. This is true even when a student doesn’t understand the teacher’s words and needs clarification. Anxiety stops students from participating in group discussions because they don’t want to be made the center of attention and are afraid of other people’s opinions of them.
3. Language:
Language is the primary way of communicating thoughts and ideas. This can be a significant communication barrier if the teacher and the students don’t speak the same language. Suppose the teacher speaks English, and the students are mostly English as a Second Language students. There will be communication problems in that case since the students may not understand everything the teacher says.
4.Expression :
Communication is never exact. The initiator tries to put his ideas into words, and then the recipient has to decode those words to understand the concept. When the teacher or student can’t choose the proper words to describe the ideas they want to convey, this will create a communication barrier in the classroom. An example of this could be a teacher who is a professional mathematician but an ineffective math teacher because the only way she can convey ideas is to use math jargon that the students cannot understand.
5. Reference Confusion:
Different explanations and applications of the same word convey a different meaning to every one of the students, for each of their backgrounds varies and thus influences the interpretation and understanding that reference confusion occurs. For this reason, proper communication between teachers and students is not possible. Reference confusion is common in reading. The ability of two people to use the exact words and arrive at entirely different understandings is one of the great dangers in our classrooms. Other areas of knowledge, experience, background, etc., are responsible for reference confusion.
6. Daydreaming: A familiar (though avoidable) barrier to effective communication occurs when the learner daydreams, that is, when he turns away from the flow of classroom communication and dwells upon his own privately recalled understanding and experiences, which are more preoccupying than those which are identified with classroom activity. Students fail to keep their full attention in the classroom if they think about the movie seen the previous night. As a result, they cannot give their proper attention to the lectures of the important teachers, which creates a significant problem in classroom communication. This barrier can be lessened or surmounted by. Increasing the understandability of classroom communication through effective audio-visual classroom techniques.
7. Imperceptions:
Students cannot understand the teacher’s important class lecture if they have any physical problems. The psychological function can do nothing in this case. So, students may gather knowledge superficially in the classroom; thus, communication fails.
8. Disinterest:
Disinterest arises among the students due to the lack of available teaching materials, teaching systems, and efficient teachers in the classroom. Teachers should include motion pictures, films, modems, specimens, film strips, charts, diagrams, tapes, records, television, and other audio-visual materials to eradicate distance. Variety in classroom procedures and teaching materials usually heightens the interest and enthusiasm with which pupils approach their work.
9. Physical discomfort:
Students may feel pain due to insufficient internal or external equipment in the classroom, like fans, light, air, etc. For this reason, they may lose interest in listening to their teacher’s lectures. This barrier should also be considered in a classroom for proper communication between students and teachers.
Multimedia approach to teaching earning process.
Digital integration of Text, Graphics, Animation, Audio, Still images, Motion Video.
Nature of Multimedia Approach:
* Multimedia approach uses a number of media, devices, techniques in the teaching learning process.
* Multimedia approach can convey vast information and provide many sources from which student can access the information.
* Multimedia approach will improve the teaching learning process.
* Multimedia approach is not restricted to a single type of learning style. It can provide the support of a wide range of activities.
* Multimedia approach aims at providing meaningful learning experience via a mix of media in order to achieve predetermined objectives.
* Multimedia approach provides the opportunity to gain mastery of competencies and skills.
* The choice of the media has to be done carefully so that one does not hamper or reduce the effect of the other. That is each media must complement the other.
* Multimedia approach will enable the learner to get access to information in dynamic environment.
Procedure for Adopting Multimedia Approach:
The following are the six steps to be followed while adopting the Multimedia Approach
1. First stage
* In this stage, the teacher initiates the teaching learning activities.
* Teacher prepared a well prepared lesson based on the objectives formulated.
* Teacher could use a variety of media for his presentation

* The student discusses with fear students and teachers his plan of action.
4. Fourth stage
* In this stage the learner actively participates.
* He uses variety of media and materials in his self study.
5. Fifth stage
* In this stage the learner integrates theory and practice.
6. Sixth stage
* In this stage learner finds that teaching learning activities have to be organised on a higher level.
* This student involved in critical analysis, critical
Role of teacher in multimedia approach:
* Teacher has to adopt a number of methods and techniques.
* Teacher has to aware of the different available media and their availability.
* Teacher should be physically competent and to use and demonstrate the use of different medium.
* Teachers should be skillful enough to make a judicious choice of media and competent enough to mix them sequentially and in an orderly manner.
* Teachers role is that of a facilitator or manager of activities.
* Teacher has to lead his student for independent, individualised learning.evaluation and exchange of ideas.
Unit 4
UNIT-IV Modern Technologies in Education
Computer: Basic concept & types of computers
Computers are used in many fields like banking, medicine, finance and education with increased preference. With the growth of artificial intelligence, computers will soon blur lines between man and machine.
Under such circumstances, a rudimentary knowledge of computers is essential for everyday work. For those who are not yet familiar with computers, now is the time to gain knowledge about this field. As children will be living with this scenario in future, their employment capability will be tested against computers. To make them future- ready, it is essential to prepare them for this inevitability.
You may have been using your computer for ages without knowing what its essential components, history, or even computer definition are. But now with your children ready to take the next step into learning computers, you may be beset by various questions that you cannot seem to answer.
This article is for those parents and their children who want to know what a computer is and what its various components are?
Definition of a Computer:
While you may have seen and used a computer but you may still be unable to answer what is computer correctly. which computes or calculates. It is a machine that takes in raw data and performs some calculations on it and gives There are many ways of defining a computer. The first and most standard definition is that a computer is something us the formed output in the desired format. Computer is also a device that stores as well as processes information electronically. Computers usually come in different sizes and grades of functionalities.
Brief History of Computers:
This journey of computers began in 1822 with Charles Babbage’s analytical engine, which was used to compute the product of numbers. Lady Ada Lovelace, considered to be the world’s first programmer, helped with the
programming of the analytical engine.
Around a hundred years later, Alan Turing presented a concept of a universal machine which could theoretically
compute anything.
Then J.V. Atanasoff, from the University of Iowa, actually made the first attempt to build a computer. But the first concrete effort came from two University of Pennsylvania professors who built the ENIAC (Electronic Numerical Integrator and Calculator) which filled an entire room and had around 18,000 vacuum tubes.
Two years later, a green light for building UNIVAC came from the US government to make the first computer for commercial and business applications. Then came a fundamental design switch to transistors a year later when modern computers. transistors replaced vacuum tubes. This paved the way for integrated circuits which form the processor chip of modern computers.
In 1953, the first programming language COBOL was developed, and FORTRAN followed it up. But the shift of computers beyond the scientific world came in 1964 when Douglas Engelbart showed a computer prototype with a mouse and a Graphical User Interface. It made computers user friendly and made them favourable for general use.
Following this, there was a parabolic rise in the development of computers with Bell Laboratories, IBM and Apple Inc. They made significant headways into the development of computers.
Apple announced the new personal computers that eventually took over the market in 1976. This was followed up by Microsoft’s Windows. These two significant companies prove to be the game changers in the personal computer field, and the rest is history.
Types of Computers:
Computers can be differentiated based on their modes of functioning as well as their size and functionality. Here they have been divided into different types of computers without considering any of these factors.
1. Analogue
These are old models of computers that work on the continuous analogue signals rather than discrete signals. They are not very accurate but extremely fast.
2. Digital
Computers that use this binary system of counting using electrical pulses of ON and OFF are known as digital computers. They function on discrete values and are generally more accurate.
3. Hybrid
Computers that have features of both digital and analogue computers are known as hybrid computers. The analogue part of a computer handles very complicated mathematical computations while digital components handle these numerical and logical systems.
4. Mainframes
Mainframe computers are computers that are accessed simultaneously by several thousands of people at once. They are used in fields of banking and telecom where they have to handle millions of requests together in minimal
time.
5. Supercomputers
These massive computers are used in the fields of engineering and scientific computations. They usually perform over a million instructions per second.
6. Servers
Servers are large repositories of information. They supply information to any computer that is on the same network as them. Many people access servers at the same time so servers need to handle large amounts of traffic.
7. Workstation
This type of computer that scientists and engineers may be familiar with is called the workstation. It is generally used in scientific applications and has a faster microprocessor along with a spacious memory.
8. Microcomputer
This last type of computer is a microcomputer which is nothing but a personal computer that you use at home. These computers are built for light use such as listening to music, or playing movies or accessing the internet.
Components of computer :
There are basically three important components of a computer
1. Input Unit
2. Central Processing Unit(CPU)
3. Output Unit
1. Input Unit:
The input unit consists of input devices that are attached to the computer. These devices take input and convert it into binary language that the computer understands. Some of the common input devices are keyboard, mouse, joystick, scanner etc.
* The Input Unit is formed by attaching one or more input devices to a computer.
* A user input data and instructions through input devices such as a keyboard, mouse, etc.
* The input unit is used to provide data to the processor for further processing.
2. Central Processing Unit(CPU):
Once the information is entered into the computer by the input device, the processor processes it. The CPU is called the brain of the computer because it is the control centre of the computer. It first fetches instructions from memory and then interprets them so as to know what is to be done. If required, data is fetched from memory or input device. Thereafter CPU executes or performs the required computation, and then either stores the output or displays it on the output device. The CPU has three main components, which are responsible for different functions: Arithmetic Logic Unit (ALU), Control Unit (CU) and Memory registers
A. Arithmetic and Logic Unit (ALU): The ALU, as its name suggests performs mathematical calculations and takes logical decisions. Arithmetic calculations include addition, subtraction, multiplication and division. Logical decisions
involve the comparison of two data items to see which one is larger or smaller or equal.
* Arithmetic Logical Unit is the main component of the CPU
* It is the fundamental building block of the CPU.
* Arithmetic and Logical Unit is a digital circuit that is used to perform arithmetic and logical operations.
B. Control Unit: The Control unit coordinates and controls the data flow in and out of the CPU, and also controls all the operations of ALU, memory registers and also input/output units. It is also responsible for carrying out all the instructions stored in the program. It decodes the fetched instruction, interprets it and sends control signals to input/output devices until the required operation is done properly by ALU and memory.
* The Control Unit is a component of the central processing unit of a computer that directs the operation of the processor.
* It instructs the computer’s memory, arithmetic and logic unit, and input and output devices on how to respond to the processor’s instructions.
* In order to execute the instructions, the components of a computer receive signals from the control unit.
* It is also called the central nervous system or brain of the computer.
C. Memory Registers: A register is a temporary unit of memory in the CPU. These are used to store the data, which is directly used by the processor. Registers can be of different sizes(16 bit, 32 bit, 64 bit and so on) and each register inside the CPU has a specific function, like storing data, storing an instruction, storing address of a location in memory etc. The user registers can be used by an assembly language programmer for storing operands, intermediate results etc. Accumulator (ACC) is the main register in the ALU and contains one of the operands of an operation to be performed in the ALU.
Memory attached to the CPU is used for the storage of data and instructions, and is called internal memory The internal memory is divided into many storage locations, each of which can store data or instructions. Each memory location is of the same size and has an address. With the help of the address, the computer can read any memory location easily without having to search the entire memory. When a program is executed, its data is copied to the internal memory and stored in the memory till the end of the execution. The internal memory is also called the Primary memory or Main memory. This memory is also called RAM, i.e., Random Access Memory. The time of access of data is independent of its location in memory, therefore, this memory is also called Random Access memory
(RAM).
* Memory Unit is the primary storage of the computer.
* It stores both data and instructions.
* Data and instructions are stored permanently in this unit so that they are available whenever required.
3. Output Unit:
The output unit consists of output devices that are attached to the computer. It converts the binary data coming from the CPU to human understandable form. The common output devices are monitor, printer, plotter, etc.
* The output unit displays or prints the processed data in a user-friendly format.
* The out unit is formed by attaching the output devices of a computer.
* The output unit accepts the information from the CPU and displays it in a user-readable form.

Application of Computer in the field of Education & Evaluation:
Computer technology has had a deep impact on the education sector. Thanks to computers, imparting education has become easier and much more interesting than before. Owing to memory capacities of computers, large chunks of data can be stored in them. They enable quick processing of data with very less or no chances of errors in processing. Networked computers aid quick communication and enable web access. Storing documents on computers in the form of soft copies instead of hard ones, helps save paper. The advantages of computers in education primarily include:
* Storage of information
* Quick data processing
* Audio-visual aids in teaching
* Better presentation of information
* Access to the Internet
* Quick communication between students, teachers and parents
Computer teaching plays a key role in the modern education system. Students find it easier to refer to the Internet than searching for information in fat books. The process of learning has gone beyond learning from prescribed textbooks. Internet is a much larger and easier-to-access storehouse of information. When it comes to storing retrieved information, it is easier done on computers than maintaining hand-written notes.
1. Computers are a brilliant aid in teaching:
Online education has revolutionized the education industry. Computer technology has made the dream of distance learning, a reality. Education is no longer limited to classrooms. It has reached far and wide, thanks to computers. Physically distant locations have come closer due to Internet accessibility. So, even if students and teachers are not in the same premises, they can very well communicate with one another. There are many online educational courses, whereby students are not required to attend classes or be physically present for lectures. They can learn from the comfort of their homes and adjust timings as per their convenience.
2. Computers have given impetus to distance education:
Computers facilitate effective presentation of information. Presentation software like PowerPoint and animation software like Flash among others can be of great help to teachers while delivering lectures. Computers facilitate audio-visual representation of information, thus making the process of learning interactive and interesting. Computer-aided teaching adds a fun element to education. Teachers hardly use chalk and board today. They bring presentations on a flash drive, plug it into a computer in the classroom, and the teaching begins. There’s color, there’s sound, there’s movement – the same old information comes forth in a different way and learning becomes fun. The otherwise not-so-interesting lessons become interesting due to audio-visual effects. Due to the visual aid, difficult subjects can be explained in better ways. Things become easier to follow, thanks to the use of computers in education.
3. Computer software help better presentation of information :
Internet can play an important role in education. As it is an enormous information base, it can be harnessed for retrieval of information on a variety of subjects. The Internet can be used to refer to information on different subjects. Both teachers and students benefit from the Internet. Teachers can refer to it for additional information and references on the topics to be taught. Students can refer to web sources for additional information on subjects of their interest. The Internet helps teachers set test papers, frame questions for home assignments and decide project topics. And not just academics, teachers can use web sources for ideas on sports competitions, extracurricular activities, picnics, parties and more.
4.Computers enable access to the Internet which has information on literally everything:
Computers enable storage of data in the electronic format, thereby saving paper. Memory capacities of computer storage devices are in gigabytes. This enables them to store huge chunks of data. Moreover, these devices are compact. They occupy very less space, yet store large amounts of data. Both teachers and students benefit from the use of computer technology. Presentations, notes and test papers can be stored and transferred easily over computer storage devices. Similarly, students can submit homework and assignments as soft copies. The process becomes paperless, thus saving paper. Plus, the electronic format makes data storage more durable. Electronically erasable memory devices can be used repeatedly.

Concept and types of networks:
There are different categories in which various networks can be classified, according to their size, capabilities, and the geographical distance they cover. A network is normally a group of multiple computer systems linked together in some manner so that they can share information and data between them.
Various kinds of networks facilitate different services and have different requirements to work properly. Most of the network varieties are known as different types of ‘area’ networks – this is mainly because of the history of networks, and dates back to the time when computer networks were described by their literal scale. This is no longer the situation due to new technology.
Through this article, we will learn about the computer network and their types (LAN, MAN, WAN, and more), with their usages and working.
Different Types of Computer Networks:
A computer network can be defined as a group of computers that utilize a set of common communication protocols over digital interconnections to share resources over the network. A network can be a small one including a handful of systems to a one with millions of devices spread all across the world.
The various types of networks are listed as below:
Local Area Network (LAN):
This is one of the original and very basic types of network, and also one of the simplest. LAN networks group computers together over comparatively small distances, such as within a single building or a small group of buildings, schools, offices, colleges, universities, etc to share resources such as printers, file servers, scanners, and the internet.
Often they do not contain more than one subnet and are generally controlled by a single administrator. The communication medium used for LAN is twisted pair, coaxial cable, etc, and is build with less costly or inexpensive hardware such as hubs, network adapters, and ethernet cables.
The data is carried at an extremely accelerated rate in the Local Area Network with added higher security. It principally works on private IP addresses and does not include heavy routing. LAN can be wired, wireless, or in both styles at once.
Personal Area Network (PAN):
The smallest and most primary type of network, a PAN is composed of a wireless modem, a computer or two, phones, laptops, Bluetooth-enabled devices or infrared-enabled devices, media player, printers, tablets, etc., and revolves around one individual in one building.
This may also incorporate a wireless computer keyboard and mouse, Bluetooth-enabled headphones, wireless printers, and TV remotes. These types of networks are typically observed in small offices or residences and are controlled by one person or organization from a single device.
PAN possesses a connectivity span of up to 10 meters. There are two types of Personal Area Network: Wired Personal Area Network and Wireless Personal Area Network.
Metropolitan Area Network (MAN):
MAN is a kind of network which is bigger than a LAN but smaller than a WAN and incorporates properties of both. It typically covers a town or city and is controlled by a single person or company, such as a local council or a large company. The most extensively used protocols in MAN are RS-232, ATM, Frame Relay, ISDN, ADSL, OC-3, etc. It has a longer range than Local Area Network(LAN).
This type of network can be applied to connect citizens with various Organisations for example communication between the banks in a city, employed in college within a city, Government and private organizations use MAN to connect all its offices within the city.
Wide Area Network (WAN):
This is another kind of the original category of network and is Slightly more complex than a LAN. WAN networks encapsulate computers together over huge physical distances, remotely connecting them over a network and allowing them to communicate even when far apart.
The Internet is an example of WAN which connects computers all around the world together. WANs are generally too large to be controlled by one administrator, and so generally have collective ownership, or in the case of the internet, is publicly owned. WAN is a general connection between LANS and MANS, that is not restricted to a single location, but it traverses over a large geographical area through a telephone line, fibre optic cable, microwaves, or satellite links.
A Wide Area Network is extensively applied in the field of business, government, and education. The data communication is slowest in WAN due to the largest distance. The installation cost of WAN is very high and utilizes advanced technologies such as Asynchronous Transfer Mode (ATM), Frame Relay, and Synchronous Optical Network (SONET).

Concept of e-learning, its trends, attributes, and opportunities:
E-learning also called electronic learning or web-based training — is anywhere, anytime instruction delivered over the internet or a corporate intranet to students and other learners via a browser. Contrary to traditional learning methods, e-learning lets students, employees in training and casual learners participate in an organized learning experience regardless of their physical location.
In its formative years, e-learning tools primarily enabled the delivery of learning material directly from a teacher to a learner. Now, the e-learning experience has evolved to enable more multidirectional communication using increasingly interactive tools. Learners have greater freedom in choosing how they receive and respond to e- learning content, and any number of peers can be involved.
Importance of e-learning:
E-learning methods and technology are important both for educating students and for the professional development of employees in the workforce.
The rapid evolution of technology has made it increasingly important for employees to have the right skills and training. For example, it’s expected that the emergence of quantum computing capabilities will create a massive shift in the way modern businesses operate that will affect coders, hardware developers and online security professionals. Learning environments, such as e-learning, will play a key role in retraining and reskilling many of these people.
In addition, companies are increasingly turning to online learning for ongoing training and upskilling employees. Learning management systems (LMSes) are particularly popular in corporate settings. Higher education institutions also use online learning methods along with internet-capable electronic devices, both inside and outside of traditional classrooms. According to McKinsey & Company’s 2022 survey of 7,000 students in 17 countries, 65% of higher education students want schools to retain aspects of online learning in the post-pandemic world.
Online education is delivered using a combination of static and interactive methods. Static approaches include learning portals, hyperlinked pages, screen cam tutorials, streamed audio and video and live web broadcasts. Interactive methods are approaches such as discussion forums, chats and desktop video conferencing. ferencing.
There are three main criteria an enterprise should follow to ensure an effective e-learning program:
* Mobile-friendly. People live on their devices, and e-learning must take advantage of that. Training prompts, other reminders and congratulations on training achievements should be sent to smartphones and other mobile devices through mobile apps.
* Social features. Social media, or a platform that emulates social media’s basic features, can give learners a way to receive updates, respond to training requirements and communicate with peers and managers.
* Instructional design. E-learning experiences should use a wide range of offerings to suit diverse learning styles, including quizzes, infographics, podcasts, demonstrations and narrative-based training materials. E- learning course development apps use authoring tools that allow even those without coding experience to create these different offerings.
Types of e-learning:
There are two primary models of web-based learning systems:
* synchronous, also known as instructor-led
* and asynchronous or self-directed and self-paced.
Basically, synchronous e-learning requires participants to be present, albeit virtually, at the same time, whereas asynchronous e-learning does not.
Examples of synchronous e-learning methods include the use of scheduled and timed online tests, virtual classrooms, web conferencing technology and interactive shared whiteboards that learners can use to collaborate. Examples of asynchronous e-learning methods include the use of discussion boards, discussion groups and self-
paced learning courses.
Advantages of e-learning:
There are many benefits of e-learning, which proponents believe outweigh the disadvantages. They include the following:
* On-demand availability. E-learning tools and services meet the needs of those with busy schedules because they’re commonly always available on demand. Learners can access material delivered online as long as they have access to the e-learning application.
* Not requiring travel. E-learning is especially conducive to cohort learning where groups of people who live in different locations work on obtaining a new skill or knowledge set
* Cost efficiency. In a traditional, in-person classroom setting, the cost of the space, infrastructure, maintenance and materials adds up. Most of these costs go away when learners online.
* Flexibility. Web-based training and e-learning enable flexibility, letting learners consume information at their own pace.
E-Book and E-Magazine, Electronic Journals and E-Readers, E-Coaching, E-Tutorial and E-Moderation:
