Piaget's Cognitive Development Theory

The constructivist approach in teaching emphasizes student-centered learning where students actively construct their own knowledge through hands-on activities, problem-solving, and collaboration. This approach views students as active participants in their own learning process and encourages critical thinking and inquiry-based learning. Teachers act as facilitators, guiding and supporting students as they discover and make connections between new information and their existing knowledge.
