Realism vs. Constructivism in Contemporary Physics: The Impact of the Debate on the Understanding of Quantum Theory and its Instructional Process

TL;DR

This paper explores how integrating philosophical debates between realism and constructivism into quantum mechanics education can enhance understanding by proposing a realist interpretation aligned with modern quantum theory.

Contribution

It introduces a novel realist interpretative scheme compatible with quantum theory, aiming to improve physics instruction and conceptual understanding of nature.

Findings

A realist interpretation of quantum mechanics is feasible and necessary.

Traditional metaphysical views of reality require revision for quantum understanding.

Proposed interpretative scheme can facilitate conceptual reconstruction in learners.

Abstract

In the present study we attempt to incorporate the philosophical dialogue about physical reality into the instructional process of quantum mechanics. Taking into account that both scientific realism and constructivism represent, on the basis of a rather broad spectrum, prevalent philosophical currents in the domain of science education, the compatibility of their essential commitments is examined against the conceptual structure of quantum theory. It is argued in this respect that the objects of science do not simply constitute 'personal constructions' of the human mind for interpreting nature, as individualist constructivist consider, neither do they form products of a 'social construction', as sociological constructivist assume; on the contrary, they reflect objective structural aspects of the physical world. A realist interpretation of quantum mechanics, we suggest, is not only possible but also necessary for revealing the inner meaning of the theory's scientific content. It is pointed out, however, that a viable realist interpretation of quantum theory requires the abandonment or radical revision of the classical conception of physical reality and its traditional metaphysical presuppositions. To this end, we put forward an alternative to traditional realism interpretative scheme, that is in harmony with the findings of present-day quantum theory, and which, if adequately introduced into the instructional process of contemporary physics, is expected to promote the conceptual reconstruction of learners towards an appropriate view of nature.
