This is a vast and vague topic. In order to do justice to it one has to write a book or maybe more than one. For it can be understood in quite different ways and on different levels. For example you may think mainly of the historical aspect, that is how philosophy of science developed in the last hundred or so years and how its influence on education changed; you may think of quite different schools of philosophy, from Marxist or positivist to such exotic but at some places influential philosophic positions like that of Rudolph Steiner; of course, you may limit the subject to special fields like epistemology, theory of scientific methodology, or, what has become fashionable recently, sociology of knowledge which may have a considerable bearing on physics teaching (Collins and Shapin 1983; Jung 1985). Again we may think of the topic treated by a philosopher, a scientist, an educationalist, a teacher, which would mean quite a difference. I am trying here to speak as an educationalist, with the physics teacher in mind: this is my vocational perspective as someone who educates physics teachers. Of course, our main concern is the contribution of science, especially physics, to general education, which integrates many of the special topics mentioned. Philosophy of science comes in because it is not at all clear what science and physics is, and what of it should be taught, and how such chosen parts should be taught. I also take this opportunity to give an idea of the longstanding tradition of this discussion in Germany, connected with names like Wagenshein, Litt, Heisenberg and many others.
