Constructivism comes in a number of forms. Some are models of learning which involve few, if any, startling epistemological claims. On the other hand, what has been promoted as ‘radical constructivism’ holds that our concepts cannot be related directly to an external reality, and that claims for the objectivity of knowledge are therefore unjustified. This standpoint is an anti-realist version of evolutionary epistemology. I argue that it relies on a mistaken interpretation of the Darwinian theory of evolution by natural selection, (...) and that its application of this model to the relation between knowledge and the world is also mistaken.

The republication of David Bloor's Knowledge and Social Imagery is evidence of the continuing interest and importance of the work but also provides the clearest evidence of the shortcomings of the enterprise. The new Afterword of Bloor's second edition addresses criticisms of the Strong Programme, but the theses which Bloor now defends are substantially weaker claims than the iconoclastic tenets of the original manifesto. Moreover, in a related strategy, Bloor asserts that criticisms made since 1975 have given him no reason (...) to modify the original text, but there are judicious alterations which are revealing. These unacknowledged alterations are documented here. Bloor's Strong Programme was founded on the diametrical opposition between his causal sociological approach and the allegedly a?causal rationalist, psychologist or ?teleological? approach. However, once it was shown that the teleological position is not the straw?man he represented it to be, Bloor's diametrical opposition left him no retreat. Just as Bloor weakens the original claims of the Strong Programme to make them appear compatible with cognitive science, so he eradicates the suggestion that the opposing teleological position was ever as absurd as he had portrayed it. The common rationale of these independent tactics leaves little question about their purpose ? and their futility. (shrink)

Abstract The accumulated case studies in the Sociology of Scientific Knowledge have been taken to establish the Strong Programme's thesis that beliefs have social causes in contradistinction to psychological ones. This externalism is essentially a commitment to the stimulus control of behaviour which was the principal tenet of orthodox Skinnerian Behaviorism. Offered as ?straight forward scientific hypotheses? these claims of social determination are asserted to be ?beyond dispute?. However, the causes of beliefs and especially their contents has also been the (...) subject of intense study in the quite different domain of cognitive science where internal states, images, rules, representations and schemas are postulated as explanatory constructs. Such explanations which postulate mental states are described by Bloor as infected by the ?disease? of ?psychologism? and Bloor has defined his Strong Programme in terms of its diametrical opposition to mentalistic theories. For example, Bloor has explicitly endorsed the Behaviourist rejection of mental representations such as images. Accordingly, a direct comparison of these radically divergent approaches to a common subject matter is of considerable interest. The paper attempts to reveal the unnoticed enormity and recidivism of the sociological programme, and how its vulnerability is betrayed in Bloor's response to criticism on central issues. (shrink)

Radical constructivism has had a major influence on present-day education, especially in the teaching of science and mathematics. The article provides an epistemological profile of constructivism and considers its strengths and weaknesses from the standpoint of its educational implications. It is argued that there are two central problems with constructivism: anti-realism and individualism which, in turn, lead to difficulties associated with idealism and relativism which, together, prove fatal for the theory.

Constructivism claims to be a postepistemology that replaces ‘traditional’ concepts of knowledge. Supporters of constructivism have argued that progress requires that pre‐service teachers be weaned off traditional approaches and that they should adopt constructivist views of knowledge. Constructivism appears to be gaining ground rapidly and should no longer be viewed as an exercise in radical thinking primarily aimed at generating innovative teaching. It has become an integral part of the pedagogic mainstream. Close examination of the theoretical foundations of constructivism, however, (...) reveals that the basic assumptions of constructivism are flawed. Far from being a postepistemology, constructivism simply regresses to a pre‐Renaissance mindset with theology replaced with a psychologism. Constructivists should be aware that the implications of constructivism for future generations may be both profound and non‐benign. (shrink)

There are almost as many versions of realism as there are antirealists, each ready to supply a preferred characterization before undertaking demolition. Even in the case of scientific realism, my topic here, I recognize two major antirealist themes.

Constructivism rejects the metaphysical position that “truth”, and thus knowledge in science, can represent an “objective” reality, independent of the knower. It modifies the role of knowledge from “true” representation to functional viability. In this interview, Ernst von Glasersfeld, the leading proponent of Radical Constructivism underlines the inaccessibility of reality, and proposes his view that the function of cognition is adaptive, in the biological sense: the adaptation is the result of the elimination of all that is not adapted. There is (...) no rational way of knowing anything outside the domain of our experience and we construct our world of experiences. In addition to these philosophical claims, the interviewee provides some personal insights; he also gives some suggestions about better teaching and problem solving. These are the aspects of constructivism that have had a major impact on instruction and have modified the manner many of us teach. The process of teaching as linguistic communication, he says, needs to change in a way to involve actively the students in the construction of their knowledge. Because knowledge is not a transferable commodity, learning is mainly identified with the activity of the construction of personal meaning. This interview also provides glimpses on von Glasersfeld’s life. (shrink)

Jean Piaget was one of the most salient and inspirational figures in psychological and educational research this century. He was prolific, authoring or editing over eighty books and numerous journal papers which have spawned a huge and fertile continuation of his research over the decades. A major component of any course on children's psychological development and a research tradition that is expanding, scholars need access to the original texts rather than relying on secondhand accounts. Jean Piaget: Selected Works is a (...) chance to acquire key original texts, most of which have been previously unavailable for several years. (shrink)

Context: The current situation in philosophy of science includes central, ongoing debates about realism and anti-realism. The same question has been central to the theorising of radical constructivism and, in particular, to its implications for educational theory. However the constructivist literature does not make significant contact with the most important, mainstream philosophical discussions. Problem: Despite its overwhelming influence among educationalists, I suggest that the “radical constructivism” of Ernst Glasersfeld is an example of fashionable but thoroughly problematic doctrines that can have (...) little benefit for practical pedagogy or teacher education. My critique has a positive goal: it is important to understand why constructivism has generated such severe polarization and disputation. A symptom of the problem is the concern with the most abstruse and obdurate problems of philosophy that have no conceivable bearing on educational practice or anything else, for that matter. The diagnosis is confirmed by those pedagogical recommendations that are allegedly derived from radical constructivism that are touted as revolutionary but are platitudes of common sense. I suggest that, ironically, this observation itself provides some pedagogical insight. Method: The approach adopted for the topic is critical, philosophical analysis of the various claims and theses of radical constructivism in the light of philosophy of science and psychology. Results: The findings of the paper are that central theoretical claims of constructivism are couched in an unclear and unnecessary jargon that obscures the implausibility or banality of these claims. Implications: The value of the paper lies in providing an analysis and critique of central, influential claims of radical constructivism both in relation to issues in epistemology and also in relation to the alleged bearing of these claims on pedagogy. It is suggested that, contrary to the claims of radical constructivists, there are few if any implications for practice and applications. (shrink)
