Constructivism is a theory of learning that has roots in both philosophy and psychology.
The essential core of constructivism is that learners actively construct their own knowledge and meaning from their experiences. This core has roots that extend back through many years and many philosophers, including Dewey , Hegel , Kant , and Vico. Philosophically, this essence relies on an epistemology that stresses subjectivism and relativism, the concept that while reality may exist separate from experience, it can only be known through experience, resulting in a personally unique reality. These four fundamental tenets provide the foundation for basic principles of the teaching, learning, and knowing process as described by constructivism.
