Hi Ibrahim,
A few years ago, The Faculty of Medicine at Lausanne University
(Switzerland) introduced Problem-Based Learning in its curriculum.
I saw a video introducing this approach as applied to teaching clinical
skills: It did sound interesting. If you are interested, I could fing ou
whom to contact here in Lausanne. I know they tried this in
collaboration
with the University of Geneva.
You may want to try the site of the faculty of medicine:
