Classroom Implications & Criticisms
The pedagogy questions turn on what Piaget means for teaching. Because children construct knowledge by acting on the world, teaching should be activity-based and discovery-oriented, with concrete materials and hands-on experience matched to the child's stage (readiness) — you cannot rush a child into a stage by drilling. The teacher is a facilitator who arranges the environment and provokes productive disequilibrium, not a lecturer pouring in facts. Errors are valuable windows into a child's current schemas, not just mistakes to punish. Now the criticisms, which CTET also tests: Piaget underestimated young children's abilities (with simpler tasks, conservation and perspective-taking appear earlier); he underplayed the role of culture, language and social interaction (Vygotsky's central objection); development is more continuous and domain-specific than his neat universal stages suggest; and the ages are approximate, with individual and cultural variation.

Key Concepts — Quick Reference
The four stages (memorise the ages cold)
| Sensorimotor | 0–2 yrs · senses & action · object permanence |
|---|---|
| Preoperational | 2–7 yrs · symbols & language · egocentrism, no conservation |
| Concrete Operational | 7–11 yrs · logic on concrete things · conservation, reversibility |
| Formal Operational | 11+ yrs · abstract & hypothetical reasoning |
How thinking changes
| Schema | A mental framework for organising knowledge |
|---|---|
| Assimilation | Fit new information INTO an existing schema |
| Accommodation | CHANGE the schema to fit new information |
| Equilibration | The drive to balance assimilation & accommodation |
