Child Development, Nutrition, and Learning: A Comprehensive Guide
Child Development, Nutrition, and Learning
Psychological Processes and the Zone of Proximal Development
According to Vygotsky, psychological processes occur on two levels, influenced by the Zone of Proximal Development (ZPD):
- Actual Development Level: Activities a child can perform independently.
- Potential Development Level: Activities a child is learning and requires assistance with. Learning occurs within the ZPD through interaction, particularly between teacher and student.
Development happens within the ZPD. As tasks are internalized through learning, children become capable of independent performance.
Levels of Psychological Processes
- Interpersonal Level: Social interaction between individuals (e.g., child and adult). Language initially serves as a communication tool in this context.
- Intrapersonal Level: Internalization of processes. Language becomes inner speech, a tool for thinking.
Infant Feeding
Mixed Feeding
Mixed feeding combines natural (breastfeeding) and artificial (formula) feeding, often prescribed by pediatricians.
Advantages of Artificial Feeding
- Anyone can administer the bottle.
- Precise milk intake measurement.
- Maternal diet and lifestyle choices (food, beverages, smoking, medications) do not directly affect the infant.
Complementary Feeding
Complementary feeding supplements breastfeeding, recommended from around six months due to the decreasing nutritional value of breast milk over time.
Learning Theories: Behaviorism vs. Structuralism
Behaviorism
Behaviorists emphasize environmental influence on development. Individuals are seen as a “blank slate” shaped by experiences. Key figures include Pavlov, Watson, and Skinner.
Structuralism/Organismic Theory
Structuralists focus on internal factors and cognitive structures. Individuals actively select, organize, and respond to stimuli, leading to problem-solving through developmental stages. Key figures include Piaget, Wallon, and Freud.
Early Intervention
Early intervention is crucial for addressing developmental deficiencies, especially in early childhood. Its importance stems from:
- Nervous System Plasticity: The brain’s ability to adapt and reorganize.
- Versatility: Finding adaptive behaviors.
- Recovery Ability: Positive changes through appropriate experiences.
Piaget’s Stages of Play
- Sensorimotor Play (0-2 years): Focuses on body sensations and motor skills.
- Symbolic Play (3-6 years): Representation of objects, actions, and scenes using imagination.
- Games with Rules (5-6 years onwards): Development of logical thinking, strategy, and social skills.
Steps in Artistic Expression Activities
- Introduction
- Material Preparation
- Execution
- Cleanup
- Sharing the Experience
The Adjustment Period
The adjustment period involves separation anxiety for children entering school. It’s an internal process requiring time and understanding. The educator’s role includes:
- Respecting feelings and providing reassurance.
- Gradual introduction to the school environment.
- Organized activities for familiarization.
- Reinforcing positive behaviors.
- Family cooperation.
Cooperation Measures
- Initial interview and school visit.
- Parent visits to the classroom.
- Potential parental presence on the first day.
Nutrients and Their Roles
Types of Nutrients
- Energy-Yielding: Carbohydrates, lipids (fats), and proteins.
- Non-Energy-Yielding: Water, vitamins, and minerals.
Nutrient Composition and Caloric Intake
- Carbohydrates: Composed of carbon, hydrogen, and oxygen. Include monosaccharides, disaccharides, and polysaccharides. (4 cal/g)
- Lipids: Composed of glycerol and fatty acids. (9 cal/g)
- Proteins: Composed of amino acids. (4 cal/g)
Nutrients have energy, regulatory, and plastic (growth and repair) functions.
Water Intake
Water is essential. Infants need 100-150 ml/kg/day, while adults need 30-50 ml/kg/day.
Energy Needs
Energy needs depend on:
- Basal Metabolism: Energy expenditure at rest.
- Growth Requirements: Approximately 2.5 calories per gram of weight gained in the first year.
- Excreta Losses: About 10% of dietary intake.
- Specific Dynamic Action: Energy used for digestion and other metabolic processes.
Open vs. Closed Content
- Closed Content: Genetically determined and not modified by learning (e.g., humans cannot fly).
- Open Content: Influenced by learning and experience (e.g., language acquisition).
Gestalt Principles of Perceptual Organization
Gestalt psychology emphasizes perceiving phenomena as organized wholes. Key principles include:
- Law of Prägnanz (Good Figure/Conciseness): Stimuli are perceived in the simplest and most stable way.
- Law of Proximity: Nearby stimuli are perceived as grouped together.
