nah, pbl is more expensive than lecture based courses (think about the facilitator to class size ratio and you'll see why, caused lots of resentment when it was introduced at georges because GEP funding per head is so much higher than 5 year).
It was adopted because, as a 'self directed' process, educational theory says it should be better adapted to adult learning styles than lecture based courses are. I could go on, but I won't because people will start yawning....
I stick to the view that, whether you cater to people's 'learning styles' or not, clever people will do well with what they are given
