Ernst von Glasersfeld and His Ｒadical Constructivism

In his representative work Ｒadical Constructivism，Ernst von Glasersfeld recounts how he personally came to adopt constructive way of thinking，expounds the basic ideas on which radical constructivism was built on，and illustrates some key issues constructivism tends to deal with concerning philosophy，psychology and pedagogy． From his point of view，knowledge is by no means a reflection of the real world; instead，it more often than not embraces action schemes，concepts and thoughts． Besides，he opposes the criterion of testing knowledge by observing consistency between knowledge and ontological reality． He believes that the quality or value of knowledge should be judged by“viability”． Based on the above understanding， he put forward his educational idea characterized by radical student-centeredness． His radical understanding of education is highly likely to influence schooling to ignore teachers’impartation of knowledge and students’acquisition of book knowledge．
