Jean Piaget's theory of cognitive development is part of HTET Child Development and Pedagogy. Piaget, a Swiss psychologist, proposed that children are not passive recipients of knowledge but active constructors who build understanding through interaction with their environment. His theory explains how thinking evolves qualitatively through distinct stages from birth to adolescence.
Key ideas
- Schema: Mental frameworks or categories that help organise and interpret information. Children continuously build and modify schemas through experience.
- Adaptation: The process of adjusting schemas to new experiences through two complementary processes—assimilation and accommodation.
- Assimilation: Fitting new information into existing schemas (a child who knows "dog" calls all four-legged animals "dog").
- Accommodation: Modifying existing schemas when new information doesn't fit (learning that cats are different from dogs).
- Equilibration: The drive to balance assimilation and accommodation; cognitive conflict (disequilibrium) motivates learning.
Watch out for
- Confusing egocentrism with selfishness → Egocentrism is a cognitive limitation (inability to take others' perspectives), not a moral failing. A pre-operational child genuinely cannot understand that others see differently.
- Thinking stages have rigid age boundaries → The ages are approximate. A bright 6-year-old might show some concrete operational thinking. Focus on the sequence being fixed, not the exact ages.
- Assuming formal operations is universal → Not all adults consistently use formal operational thinking. Many adults rely on concrete thinking in unfamiliar domains. HTET may test this nuance.
Quick reference
- Four Stages in Order: Sensorimotor → Pre-operational → Concrete Operational → Formal Operational
- Conservation develops in Concrete Operational stage (around age 7)
- Piaget = Constructivist: Child actively constructs knowledge, not passively receives it
- Schema + Assimilation + Accommodation = Adaptation
- Pre-operational = Egocentric + No Conservation; Concrete Operational = Logical + Conservation achieved
