Methods of Knowledge Acquisition: Deduction, Induction, and Epistemology
Methods of Knowledge Acquisition
One method is a more or less fixed and stable process, consisting of several steps or rules that lead to an end.
Deductive Method
It involves extracting a conclusion from general principles. However, this method presents a problem in the strict sense, so it is feasible in the formal sciences.
Inductive Method
It involves developing a conclusion from specific data or individuals to general principles.
Hypothetico-Deductive Method
It is a combination of two methods: it combines

The Scientific Method
The scientific method is defined as the set of principles, rules, or standards for the study and solution of research problems. R = Scientific Method
It refers to a set of procedures, using the necessary tools or skills, to examine and solve a problem or set of research problems. R = The scientific method
Types of Scientific Methods
- Inductive Method: Derives general conclusions from particular premises.
- Deductive Method: The conclusion is implicit in the premise and goes from the
Understanding Scientific Research: Methods, Theories, and Design
Scientific Method and Knowledge
Scientific method: Modern science relies on knowledge obtained through objective observation, experimentation, and logical reasoning. This knowledge must be verified or rejected by observation. The goal is to use verified results to construct theories that explain why phenomena behave the way they do.
Components of the Scientific Method
- Empirical verification
- Falsifiability
- Non-normative research
- Transmissible
- Cumulative
- Empirical generalization
- Explanatory
- Predictive
- Probabilistic
Effective Science Teaching Methods and Objectives
Objectives in the Teaching of Science
Selecting certain content, programming different activities, selecting different programs, and preparing materials and resources are all decisions that must be made regarding what and how to teach.
Models in Science Teaching
- Transmission and reception
- Discovery
- Constructivist (aims to improve learning from experimental sciences)
Methods in the Teaching of Natural Sciences
- Experimental method
- Historical rediscovery method
- Problem method
- Heuristic (or search) method
- Investigation
Key Concepts in Science and Epistemology
Verification Criteria
Any base or means for judging the possibility of an empirical test of a scientific hypothesis. There are two classes: weak criterion and strong criterion.
Statement
A verbal expression of a proposition. In grammar, it is a descriptive or declarative sentence.
Proposition
Thinking that is expressed by a descriptive sentence or statement. Its essential feature is to be true or false. Another definition: a thought that affirms or denies something and has a real value.
Universal Statement
Every

The hypothesis serves as a *guide* to research. Even if it is difficult to establish hypotheses in studies that are reported as descriptive, it is what leads us to ask other questions. The scenarios, which lead us directly to the variables taken into account during the design and operationalization of the research, are what lead us to answer the question: What is to be collected from the previously defined social reality? Strictly speaking, a hypothesis is merely a statement about the relationship
