The process of problem‐based learning: what works and why

In this review, we portray the process of problem-based learning (PBL) as a cognitive endeavour whereby the learner constructs mental models relevant to problems. Two hypotheses are proposed to explain how learning is driven in PBL; an activation-elaboration hypothesis and a situational interest hypothesis.

Research relevant to these hypotheses is discussed. In addition, research studying the effects of various support strategies used in PBL is reviewed. Finally, we summarise a number of recent studies in which a new 'micro-analytical' methodology was used to trace the process of PBL in the natural classroom setting.
