philosophy of constructivism can be reduced to one sentence: "everything
that is said is said by an observer" (Maturana 25). As trivial as this
sentence might sound at first – the longer you think about it the more
profound it turns out to be. Constructivists deal with how conceptions of
reality come into being. Maturana and other constructivists hold the view that
an external reality exists but negate that this external world can be perceived
the way it really is. (Pörksen 12)
Ernst von Glasersfeld, one of the founders of constructivism, replaces the concept of truth by the concept of viability. Consequently, a theory should be useful (Pörksen 46). Von Glasersfeld partly bases his concept on the results of Jean Piaget, a developmental psychologist who in his book Construction of Reality in the Child explains that children actively acquire knowledge. They learn when their own actions do not correspond to their expectations, meaning they are not viable (Pörksen 66). When applied to teaching methodology, this assumption has far-reaching consequences. In the following, two schools of constructivism are introduced.
constructivists and social constructivists assume that people cannot directly
perceive the objective reality but that they rather construct their view of the
world based on knowledge they already
Radical constructivists claim that people develop their individual view of the world. Social constructivists, however, state that people only attain knowledge of their surroundings by dealing with others, that is, in social discourse. For both schools of constructivism, the criterion of viability plays the decisive role, which means that it is not 'truth as such' that matters, but usefulness (Douillet 15).
not have direct access to reality because the brain only processes electronic
signals. Reality is constructed on the basis of these signals.
Constructivists have abandoned the concept that knowledge is a kind of substance which can be transferred from the head of the teacher to the head of the learner. Learning is regarded as a creative, inventive act performed by the individual. If every learner has his/her own way of processing learning material, there have to exist 'as many individual and unpredictable ways of learning as there are learners' (Thissen 8).
Ernst von Glasersfeld demands that each learner should be treated as an intelligent, independently thinking individual (Pörksen 65).
