Learning through experimenting: an original way of teaching geometrical optics

Autor: Even, C., Balland, C., Guillet, V.

Over the past 10 years, we have developed at University Paris Sud a first year course on geometrical optics centered on experimentation. In contrast with the traditional top-down learning structure usually applied at university, in which practical se
