Understanding Cognitive Growth in Learners
Educational psychology investigates how children and adolescents acquire, process, and organize knowledge throughout their developmental journey.
Jean Piaget: Four Stages of Cognitive Development
- Sensorimotor (0-2 years): Learning through sensory exploration and motor actions; development of object permanence.
- Preoperational (2-7 years): Symbolic thought and language emergence; egocentrism and lack of conservation.
- Concrete Operational (7-11 years): Logical reasoning applied to concrete objects; understanding conservation and reversibility.
- Formal Operational (11+ years): Abstract thinking, hypothetical-deductive reasoning, and systematic problem-solving.
Lev Vygotsky: Socio-Cultural Theory and the ZPD
Zone of Proximal Development (ZPD):
The distance between what a learner can accomplish independently and what they can achieve with the guidance of a More Knowledgeable Other (MKO) through instructional scaffolding.
