The implementation of the PBL curriculum is now a mandate not a choice. However, for the established schools with large numbers of students and insufficient resources, the whole-scale conversion from traditional curriculum to PBL is almost impossible. Various alternative curricula have been introduced to many institutions, but they all have more or less shortcomings that impede the advantages of PBL approach. To solve this dilemma, I proposed a new alternative PBL curriculum, the 'Triple-phase PBL Curriculum', which is consisted with pre-PBL, PBL, and Post-PBL phase. I also explained its rationale and advantages over other alternatives.
