Constructivism is a learning theory that suggests people build their own understanding and knowledge of the world through experiences and reflection. Instead of passively receiving information, learners actively engage with new ideas, connecting them to what they already know. This approach encourages critical thinking and problem-solving, making learning more meaningful and personalized. In a constructivist classroom, teachers act as facilitators, guiding students in their exploration rather than simply delivering lectures. Activities like group projects and hands-on experiments allow students to collaborate and share perspectives, fostering a deeper understanding of concepts. This method is often associated with educational theorists like Jean Piaget and Lev Vygotsky.
