摘要：Introduction: Self-directed learning (SDL) and problem-based learning (PBL) are fundamental tools to achieve lifelong learning in an integrated medical curriculum. However, the efficacy of SDL in some clinical courses is debated. Aim: The aim of the study was to measure the effectiveness of SDL for an ophthalmology course in comparison with PBL. Methods: A cross-sectional study was conducted with fifth-year medical students enrolled in an ophthalmology course. SDL comprised four case-based scenarios guided by several questions. PBL comprised three sessions. An ear, nose, and throat (ENT) course was selected for comparison as a control. At the end of the course, 30 multiple-choice questions (MCQs) for both SDL and PBL were assessed and analyzed against their counterparts in the ENT course by an independent t -test. Results: For the SDL component of the ophthalmology course, the number and percentages of students attaining high (n = 6/60, 10%) and moderate (n = 15/60, 28.3%) scores on an MCQs written exam were evaluated. For the PBL component, high scores were seen for 23.3% (n = 14/60), and moderate scores for 33.3% (n = 20/60) of the participants. For the SDL component of the ENT course, the number and percentages of students attaining high (n = 14/60, 23.3%) and moderate (n = 17/60, 28.3%) scores were recorded. For the PBL component, high (16/60, 26.6%) and moderate (17/60, 28%) scores were recorded. Significant p -values were obtained between the results for SDL and PBL in the ophthalmology course ( p = 0.009), as well as between SDL results for both courses ( p = 0.0308). Moreover, differences between the SDL results of ophthalmology and the PBL results of ENT ( p = 0.0372) were significant. Conclusion: SDL appears to be less valuable for promotion of self-readiness. Periodic discussions in small groups or by panel discussion are strongly recommended for students to enhance readiness with SDL.
