Research reveals that successful problem solvers must possess comprehensive knowledge, and more importantly, have appropriate knowledge organization and understanding. A new taxonomy of medical problems is recommended, and it is suggested that the traditional hypothetico-deductive strategy for problem-based learning be replaced by scheme-driven…

Field testing of a series of group-learning units in pharmacology based on a patient-oriented problem-solving approach found that the units were well crafted and that students had higher scores on tests of their knowledge of pharmacology after they had used the units. (Author/DB)

Critical review of the literature on problem-based learning (PBL) in medical education focuses on: (1) the credibility of claims (both empirical and theoretical) about the ties between PBL and educational outcomes and (2) the magnitude of the effects. Concludes there is no convincing evidence that PBL improves knowledge base and clinical…

A study compared results of 2 teaching methods, traditional Socratic method (22 students) and a problem-based curriculum (35 students) in a University of Kentucky medical school surgery clerkship. Results showed the problem-based method resulted in similar knowledge level but improved clinical problem-solving skills. (Author/MSE)

A University of Limburg (Netherlands) medical school study investigated the relationship between student-generated learning issues and faculty instructional objectives (i.e., the effectiveness of the problems posed) in a problem-centered obstetrics and child development curriculum. Subjects were 120 students and 12 faculty. Results indicated…

Review of experimental evidence concerning the effectiveness of problem-based learning suggests that the approach may not improve content-free problem solving; may initially reduce learning levels but fosters long-term retention; may enhance transfer of concepts and integration of concepts into clinical problems; enhances intrinsic interest of…

A study investigated differences in National Board of Medical Examiners Part I scores for students at the College of Human Medicine (Michigan) in two preclinical medicine curricula, one problem based and one traditional, during four distinct periods. Results illustrate the difficulty of comparing the curricula, given revisions over time. (MSE)

A study investigated reasoning processes of medical students in schools with different curricular formats, a conventional curriculum with basic science taught before clinical training and a problem-based curriculum with basic science taught in the context of clinical problems. Strengths and weaknesses of each curriculum type emerged. (Author/MSE)

A study of a new University of Toronto medical school problem-based learning (PBL) curriculum found that students (n=207) and faculty (n=15) had more favorable attitudes toward PBL after direct experience with it than before. Recommendations are made for other schools and programs wishing to implement PBL curricula. (Author/MSE)

A Dutch study compared the clinical diagnostic skills of 612 medical students educated at schools with problem-based, integrated, or conventional curricula. Students responded to 30 case histories epidemiologically representative of Dutch society and all organ systems. Students trained within problem-based and integrated curricula made more…

A study investigated medical students' expectations of the medical school environment and opinions of their academic experience in three areas (teaching/administration, psychological aspects of student life, intellectual climate) near the end of their first year in two parallel curricula: a problem-based learning program and a traditional…

The Personal Progress Index, designed to assess students' knowledge at regular intervals, is administered at the McMaster University (Ontario) Faculty of Health Sciences three times annually. Feedback is provided to students, and accumulated student performance is determined for summative evaluation. Results over 4 classes (n=400) show it to be…

Innovative medical school programs discussed include a problem-based, village-centered rural program in the Philippines, a problem-oriented rural program of community medicine in Thailand, a problem-based curriculum in China, and four restructured medical curricula in the United States. Focus is on the results of the changes. (MSE)

A study evaluated 35 research projects from 1970-92 comparing problem-based learning in medical and nursing education with more traditional methods of instruction. It was found that results generally supported the superiority of the problem-based learning approach for both affective outcomes and academic performance. (Author/MSE)
