Study Notes: Piaget, Kohlberg and Vygotsky
Overview
These three theorists form the backbone of developmental psychology tested in CTET Paper 1. Jean Piaget explained how children's thinking evolves through stages. Lawrence Kohlberg built on Piaget's work to map moral reasoning development. Lev Vygotsky offered a contrasting lens, emphasizing social interaction and culture over individual maturation.
CTET expects you to identify each theory's core constructs, compare their approaches, and apply them to classroom scenarios. Questions may ask you to match a child's behavior to a Piagetian stage, recognize Kohlberg's moral reasoning level, or identify Vygotskian concepts like scaffolding and the Zone of Proximal Development (ZPD). You must also know critical perspectives—limitations and cultural biases—of each theory.
Understanding these theories helps teachers design age-appropriate instruction, support diverse learners, and foster both cognitive and moral development in primary classrooms.
Key Concepts
- **Piaget's Cognitive Development Theory**: Children actively construct knowledge through interaction with their environment. Development occurs in four fixed, universal stages: Sensorimotor (0–2 years), Preoperational (2–7 years), Concrete Operational (7–11 years), and Formal Operational (11+ years). Each stage has distinct cognitive abilities.
