Different Levels of the Meaning of Wave-Particle Duality and a Suspensive Perspective on the Interpretation of Quantum Theory

Abstract

There is no consensus on the genuine meaning of wave-particle duality and the interpretation of quantum theory. How can we teach duality and quantum theory despite this lack of consensus? This study attempts to answer this question. This research argues that reality issues are at the core of both the endless debates concerning the interpretation of quantum theory. As practical instructional frameworks, this study suggests three different levels of meaning for duality as well as a new suspensive perspective. The key idea behind these notions is a distinction between the prediction rule and the reality-related interpretation, instead of a traditional division between formalism and interpretation. After elaborating upon those notions, this study compares this new suspensive perspective with other interpretations or educational stances concerning the interpretation of quantum theory. Several practical guides for the better instruction of duality and quantum theory as well as its implication on students' understanding of the topics are also discussed.
