Constructivist Learning Theory posits that learners construct knowledge through experiences and interactions with their environment. This approach emphasizes active participation, where students engage in problem-solving and critical thinking rather than passively receiving information. Key figures in this theory include Jean Piaget and Lev Vygotsky, who highlighted the importance of social context and cognitive development in learning. In a constructivist classroom, teachers facilitate learning by providing opportunities for exploration and collaboration. Students work together on projects, discuss ideas, and reflect on their understanding, which helps them build connections between new information and prior knowledge. This method fosters deeper comprehension and retention of concepts.
