An introduction and evaluation of problem-based learning in health professions education

Problem-based learning (PBL) is a curricular innovation whose distinguishing characteristic is the use of real or simulated problems as the stimulus to student-centered learning. PBL is promoted as facilitating among students the development of critical thinking skills, resource identification, and greater retention of information. This article presents an evaluation of the benefits and concerns related to the use of PBL. Several studies suggested that while PBL may prepare practitioners as well as traditional programs do, its superiority as a teaching method needs further documentation. Such research should be conducted in other health care professions education programs in addition to medical education. PBL is an ideal method for promoting interdisciplinary education for health care professions. An example of the use of the PBL model in an interdisciplinary public health course is presented. Other considerations, including costs, that must be included in any decision to adopt the PBL approach, are also reviewed.
