Towards a historical approach to physics education

Abstract

Modern physics is a complex multiplicity of practices: theoretical, mathematical, experimental and simulation practices. Experimental and simulation practices are related to the pragmatic dimension of a physical theory. Mathematical practices are related to the syntactic dimension of a physical theory, but theoretical practices involve an often neglected semantic dimension. Physics and consequently teaching physics are usually reduced to the syntactic and pragmatic dimensions. Semantic dimension is linked to the conceptualization of the physical reality, to the conception of Nature. By neglecting the semantic dimension, physics is reduced to a pure mathematical game and to technological manipulations. Thus, the cultural aspect of science is lost and physics education is reduced to a mere technical training. This process of de-culturalization of science had its roots in the Enlightenment’s turn in physics to free it from theology and metaphysics and had its completion in the post-second-world-war era. I believe we have to recover the cultural aspects of physics to understand it more deeply in its whole complexity. We have to recover all its relationships with other disciplines as philosophy, mathematics, psychology, sociology and other sciences, even theology, which are fundamental to constitute its semantic dimension. Historical approach to physics and physics education is the only way to recover this interdisciplinarity at the roots of the various physical conceptions of Nature. In this way, for example, we can understand that beyond mechanics there is a mechanist conception of Nature, beyond thermodynamics there is a thermodynamical conception of Nature, and beyond electromagnetism there is an electromagnetic conception of Nature. These different conceptions of Nature are not compatible and their historical fight has produced the relativistic, quantum and chaos revolutions in XX century physics. These different conceptions of Nature imply different existential self-understanding of the meaning of mankind in the universe and different ethical perspectives.
