Is von Glasersfeld's constructivism actually radical? In this article, I respond to this question by analyzing von Glasersfeld's main works. I argue that the essential theoretical move of radical constructivism – namely the assertion that reality is the construction of a human mind that only responds to the subjective perception of ‘what fits’ – results in a conservative vision of reality, knowledge, and education. To the extent that the friction with, and the challenge of, reality is eliminated, knowledge remains only (...) a subjective affair and the world is reduced to a living tautology. In this way, von Glasersfeld constructs a theory of ethical disengagement in which personal responsibility is de facto denied. Thus, to the extent that education entails responsibility, change, and comparison, radical constructivism is a theory that is unsuitable for education. I also attempt to argue that the equivalence between radical constructivism and relativism and nihilism that many support is i.. (shrink)

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

A visible role in the theoretical discourses on education has been played in the last couple of decades by the constructivist epistemologies, which have questioned the basic assumptions of realist epistemologies. The increased popularity of interpretative approaches especially has put the realist epistemologies on the defensive. Basing itself on critical realism, this article discusses the ontological and epistemological commitments of educational research and its consequences for text interpretation. The article defends ontological realism and the semantic conception of truth against radical (...) constructivist ontology and the epistemic conceptions of truth. (shrink)

Two varieties of constructivism are distinguished. In part 1, the psychological or “radical” constructivism of von Glasersfeld is discussed. Despite its dominant influence in science education, radical constructivism has been controversial, with challenges to its principles and practices. In part 2, social constructivism is discussed in the sociology of scientific knowledge. Social constructivism has not been primarily concerned with education but has the most direct consequences in view of its challenge to the most fundamental, traditional assumptions in the philosophy of (...) science and to the practice of science itself.

In this essay Clarence Joldersma explores radical constructivism through the work of its most well-known advocate, Ernst von Glasersfeld, who combines a sophisticated philosophical discussion of knowledge and truth with educational practices. Joldersma uses Joseph Rouse's work in philosophy of science to criticize the antirealism inherent in radical constructivism, emphasizing that Rouse's Heideggerian critique differs from the standard realist defense of modernist epistemology. Next, Joldersma develops an alternative conception of truth, in terms of disclosure, based on Lambert Zuidervaart's work in (...) aesthetics. Joldersma concludes by arguing that this notion of truth avoids the pitfalls of both realism and antirealism, giving educational theorists a way forward to accept some of the major insights of constructivism with respect to learning and teaching without having to relinquish a robust notion of truth.
