Abstract
Background: Student-centered learning strategy increases the likelihood of graduation of competent, selfdependent, and problem-solving physicians. The University of Bisha, College of Medicine (UBCOM) adopted self-directed learning (SDL) represented by problembased learning (PBL), and directed self-learning (DSL) represented by team-based learning (TBL).
Aim: To compare the students’ performance in SDL and DSL among UBCOM students.
Methodology: A total of 502 multiple choice questions (MCQs) from the mid-course and final exams were collected by the relevant subject experts from nine courses during the period from September 2020 till June 2023 that adopted PBL and TBL; 247 MCQs related to PBL and
255 related to TBL. Psychometric analysis was used to determine difficult, easy, and optimum questions (25%, 90%, and 26e89%, respectively). Point biserial as
<0.19, 0.20e0.29, 0.30e0.39, and >0.40 which indicate poor, marginal, good, and excellent point biserial, respectively. Finally, the number of functional distractors was attempted by >5% of the candidates.
Results: No significant differences were noted for the students’ performance in MCQs related to PBL (representing self-directed, small group learning tool), and TBL
(representing directed-self, large group learning tool) regarding difficulty index (DI), point biserial, and distractors functionality.
Conclusion: It has been observed that there is no difference in students’ performance whether PBL or TBL is used for learning Basic Medical Science courses. Small group learning such as PBL needs more resources in comparison to large group learning as in TBL, therefore any institute can decide on the adopted learning strategy depending on its resources and the number of students.
