Constructivism is a learning theory that emphasizes the role of learners in actively constructing their own understanding and knowledge. It suggests that individuals build new ideas based on their prior experiences and interactions with the world. This approach encourages exploration, problem-solving, and critical thinking, allowing learners to engage deeply with the material. In a constructivist classroom, teachers act as facilitators rather than traditional instructors. They create environments where students can collaborate, ask questions, and reflect on their learning. This method is often associated with educational theorists like Jean Piaget and Lev Vygotsky, who highlighted the importance of social interaction and cultural context in learning.
