We cordially invite you to join the 3rd Asia-Pacific Joint Conference on Problem-Based Learning (APJC-PBL) which will be organized and hosted by the Faculty of Medicine, Prince of Songkla University, Thailand. It is the great opportunity for our faculty to hold this conference at the second time. The first one, named as 4th Asia-Pacific Conference on PBL, was held 10 years ago. The general goal of the 3rd APJC-PBL is to become an international meeting point for PBL educators in Asia-Pacific region to reflect and exchange ideas and experiences in researching and supporting educational development of PBL in different disciplines and at different background. Anyway, we have still encountered with various problems in implementing PBL in many schools and institutions in this region. The theme of the 3rd APJC-PBL will be PBL: Past, Present and Prospect which will focus in evolution of PBL across the times and update PBL situation in AsiaPacific context, as well as destination and prospect of PBL. The sharing of practices in PBL from different circumstances will be most valuable for rethinking of quality learning and teaching with this educational strategy
