For the interrelations between mathematics and physics teaching to get better, changes
in the curricula will be necessary, but it will not be sufficient. For each subject capable
of strengthening the relations between mathematics and physics, an epistemological
analysis has to be conducted in order to make the adequate changes. Our claim is that
this study must take into account the historical evolution of the concepts at stake and
the evolution of the teaching of these concepts, with a description of the constrains of
the educational context. Such analyses must be the bases for teaching experimented
completed by didactical analysis. Finally specific teachers’ training is necessary, in
order to make the changes possible.
