Child & Adolescent Development 🧠

Understanding how a learner grows—physically, cognitively, socially, and morally—is the foundation of effective teaching. This module covers the heavy hitters of developmental psychology.

1. Cognitive Development: Jean Piaget

Piaget focused on how children "construct" their understanding of the world.

Sensory-Motor (0-2 yrs): Learning through senses and motor activities.
- Key Concept: Object Permanence (Knowing an object exists even when hidden).
Pre-operational (2-7 yrs): Use of symbols/language.
- Key Concept: Egocentrism (Thinking everyone sees what they see) and Centration (Focusing on only one aspect of a situation).
Concrete Operational (7-11 yrs): Logical thinking begins but only for concrete objects.
- Key Concept: Conservation (Knowing the amount stays the same even if the shape changes).
Formal Operational (11+ yrs): Abstract and hypothetical thinking.
- LET Scenario: A teacher asks a student: "What would happen if humans could fly?" A student who can answer this logically is in the Formal Operational stage.

2. Psychosocial Development: Erik Erikson

Erikson's "Crisis" theory explains social development throughout life.

Trust vs. Mistrust (0-1.5): Foundation of hope.
Autonomy vs. Shame/Doubt (1.5-3): "I can do it myself!"
Initiative vs. Guilt (3-6): Purpose and exploration.
Industry vs. Inferiority (6-12): School age. Focus on competence.
- LET Scenario: A student feels bad because they can't draw as well as their classmates. They are struggling with Industry vs. Inferiority.
Identity vs. Role Confusion (12-18): "Who am I?"
Intimacy vs. Isolation: Early adulthood relationships.

3. Moral Development: Lawrence Kohlberg

Pre-conventional: Focus on self (Punishment and Reward).
Conventional: Focus on others (Good Boy/Nice Girl and Law & Order).
- LET Scenario: A student follows school rules simply because they don't want to be called a "rule-breaker" by their peers. This is Stage 3: Good Boy/Nice Girl.
Post-conventional: Focus on principles (Social Contract and Universal Ethics).

4. Sociocultural Theory: Lev Vygotsky

Vygotsky believed social interaction is the key to learning.

ZPD (Zone of Proximal Development): The gap between what a child can do alone vs. with a "More Knowledgeable Other" (MKO).
Scaffolding: Temporary support (like training wheels) that is gradually removed.
- Example: A teacher provides a "fill-in-the-blanks" outline for an essay, then removes it for the next project.

5. Ecological Systems Theory: Urie Bronfenbrenner

This theory looks at the "layers" of environment that affect a child.

Microsystem: Immediate environment (Family, school, peers).
Mesosystem: Connections between microsystems (e.g., Parent-teacher meeting).
Exosystem: Indirect environments (e.g., A parent's stressful workplace affecting the child at home).
Macrosystem: Cultural values, laws, and customs.
Chronosystem: The element of time (e.g., The impact of a divorce or a pandemic over time).

💡 LET Strategy: Developmental Cues

When answering questions about developmental stages, look for the Age and the Core Conflict.

Age Cues:
- 7-11 years = Concrete Operational (Piaget) or Industry (Erikson).
- 12-18 years = Formal Operational (Piaget) or Identity (Erikson).
The "Longest Option" Pattern in Development:
- Correct answers often include specific developmental terms (e.g., "Cognitive Equilibrium," "Scaffolding," or "Animistic Thinking") to be technically accurate.
- BUT WATCH OUT: Don't pick a long answer if it mixes up the names (e.g., "Piaget's stage of Industry vs. Inferiority" — Wrong! That's Erikson).
Holistic Approach: The LET favors answers that treat the child as a "whole person"—emotional, social, and physical needs are just as important as cognitive ones.
