The fuzzy world of problem based learning.

The AMEE Guide by Taylor & Miflin (2008) in this issue of Medical Teacher offers an excellent critical review on PBL as it is understood and implemented in 2008, reflecting the experience, understanding and position of the authors. As an advocate of PBL and with personal experience of working for 30 years in three medical schools adopting integrated PBL curricula-The Suez Canal University, Egypt, Arabian Gulf University, College of Medicine, Bahrain and the University of Sharjah, College of Medicine, U.A.E. - I have witnessed its evolution and implementation in different contexts and cultures. While keeping an open mind about variabilities in its implementation, and without being entrenched in the orthodoxy of the original philosophy, perhaps I may be able to reflect on some aspects of this controversial and challenging educational strategy.
