Online Problem-Based Learning Intervention on Self-Directed Learning and Problem-Solving through Group Work: A Waitlist Controlled Trial

Background: Small group work embraces independent study and interactive learning, which enhance knowledge acquisition and skills. Self-directed learning (SDL) and problem-solving (PS) are essential skills in the development of the nursing profession. During the coronavirus pandemic, virtual learning was indispensable. However, little is known about how students develop SDL and PS abilities through online learning through group work. Objective: To evaluate the effects of the online intervention on SDL and PS abilities through interactive group work. Methods: A randomised waitlist-control trial was carried out. A structured intervention using problem-based learning (PBL) as a guideline was used to direct student learning in small group work. Assessments were scheduled at Time 0 (baseline), Time 1 (8th week), Time 2 (16th week), and Time 3 (28th week). Results: The mean student age was 21.45 (SD = 0.86). About 78% of students were female. There was no significant difference in demographic characteristics and analysis at the baseline. Students in the intervention group reported greater improvement in the SDLRS and PSI at the 8th week, whereas those in the waitlist control group reported greater improvement in the SDLRS and PSI at the 16th week. Sustained effects in the SDLRS and PSI were observed in both the intervention and waitlist control groups at the 16th and 28th weeks, respectively. A repeated-measure analysis was performed to compare the SDLRS and PSI in different periods and revealed statistically significant results (p < 0.001) in all subscales of SDLRS and PSI in the four study periods. Conclusions: The guidelines appear to be an effective treatment for SDL and PS ability enhancement with sustainable effects through interactive group work. The guidelines with explicit instructions and learning objectives provide directions and guidance to students to learn more effectively. The educator plays a vital role in facilitating the students’ SDL and PS ability improvement.
