Challenges and relevance of problem-based learning in dental education.

Abstract

The rôle of PBL as an innovative approach in medical education has been well documented. There has been an emerging trend of incorporating PBL into the dental curriculum. The potential advantages of PBL as a mode of learning encompass the enhancement of an integrated approach in solving dental-treatment-related problems, the development of critical thinking and problem solving skills and the encouragement of independent life-long learning. PBL was introduced into the dental curriculum as a pilot project in the Faculty of Dentistry, National University of Singapore in summer 1996. An example of a case-based study was illustrated and the learning objectives of the study were highlighted. Initial feedback from students indicated a positive attitude to this mode of learning in terms of cognitive, affective and psychomotor skills. Strategies to enhance learning in the PBL environment include time allocation for self-study, availability of resource materials and use of appropriate assessment methods. Problems that remain to be resolved include the choice of appropriate outcome assessment measures to evaluate the effectiveness of PBL as a mode of learning in undergraduate dental education.
