Proof that PBL works vs. standard lectures
I am looking for a study or some proof that PBL works better than standard lecture based classes. Yes, I know that it is obvious, or should be. However, for people who have never been exposed to PBL and are used to only lecture classes, it can be a hard concept.
I need something fairly easy to understand that I can show traditional teachers and those who have little/no experience with PBL. If possible, some numbers, such as percentages, would be very useful.
I've been looking, but have not found this kind of thing.
If you could help me out, I'd really appreciate it.
Thanks a lot.
