Constructivism is a theory of learning. Its root exists in philosophy and psychology. The important thing about constructivism is that the learners construct their own knowledge. Von Glasersfeld presents the three epistemological tenets in which fourth has been added recently, "Knowledge cannot be acquired by being passive, it is the result of the active cognition", "Cognition is an adaptive process that updates human behaviour in the available environment", "Cognition organizes experiences that make up human senses" and the roots of knowledge exist in both biological constructivism, social and cultural interaction. Constructivism accepts the importance of the learner's active role in the formation of knowledge. The personal and social experiences are important in acquiring knowledge. Each person constructs his or her own knowledge on the basis of self-experience.
