Problem-based learning at the University of Southern California School of Dentistry

Responding to the recent Institute of Medicine report on dental education, the Center for Craniofacial Molecular Biology (CCMB) of the University of Southern California School of Dentistry has developed a parallel track program in dental education leading to the D.D.S. degree. This program was proposed in May of 1995, and the first class of twelve students was admitted in September of that year. Currently two classes are enrolled and plans to admit a further twelve students (Class of 2001) are in place. The educational strategy for this program is totally problem-based. Students work in groups of six with a faculty facilitator, not necessarily a content expert. Facilitators are largely drawn from the multidisciplinary pool of research faculty at the center. All learning is mediated through biomedical and biodental problem cases. No formal lectures or classes are scheduled. The learning of clinical dental skills is promoted through focussed dental patient simulations in which students review clinical charts, radiographs, medical reports and then explore identified, hands-on learning needs using patient simulators in a clinical context. Early patient exposure is obtained through dental office visits and other special patient clinics. Initial experience with this program suggests that the problem-based learning (PBL) students learn as well (if not better) than their traditional program peers and develop excellent group and cognitive analytical skills. The absence of a pool of dentally related biomedical cases suitable for a PBL program has necessitated the use of innovative approaches to their development and presentation. It is believed that this educational approach will produce dental clinicians equipped with the self-motivated, life-long learning skills required in the ever-changing world of bio-dental sciences in the twenty-first century.
