Oops, just check my email and I received a reply:
"To put the change in perspective, we have a 3 year implementation plan that begins next fall. All courses will eventually be taught under 4 themes: health and well-being, disease processes, restoration of health and maintenance of health. There are also 2 threads woven throughout: leadership and inquiry. Together we believe this will provide an integrated approach to learning. We will begin with small group learning next fall in some of the basic science courses. However, we will continue to have lectures and seminars throughout. Our approach is a hybrid of PBL for the small group sessions."
Not TOO specific as to how much time would be spent on PBL. I guess I'd enjoy a hybrid more than full PBL...sounds good to me.
