Constructivism

A philosophical viewpoint on how the mind forms and modifies its understanding of reality

According to Ernst von Glasersfeld, our resident philosopher and expert on constructivism:

Constructivism was introduced in the modern era by Jean Piaget as a way of thinking about cognition and knowledge, not as a metaphysical theory about what might exist.

It's fundamental tenet is: The mind organizes the world by organizing itself (Piaget 1937).

The "radical" version of constructivism was developed independently by Heinz von Foerster (1981) and Ernst von Glasersfeld (1984). Knowledge, from this perspective, is not a representation of "objective" facts, but a compendium of concepts, conceptual relationships, and rules that have proven useful in domesticating our experiential world.

Constructivism and Science Education

In what way is a constructivist view of science education different from other views? The answer lies in the tenets of constructivist philosophy, which assert that all knowledge is constructed as a result of cognitive processes within the human mind. While this may appear to be a harmless enough statement, many find (so-called) radical constructivism somewhat unpalatable.
