This document summarizes key aspects of constructivism as a learning theory. According to constructivism, students learn through their own experiences and use critical thinking skills, while teachers guide students and help steer them in the right direction. Key contributors to constructivism included Jean Piaget, John Dewey, Jerome Bruner, and Lev Vygotsky. Constructivism has implications for both students, who take a more active role in their learning, and teachers, who act as facilitators rather than just instructors.
