Abstract:
Objective In problem-based learning, students are often found difficult to con-struct medical knowledge systematically and transfer knowledge to solve new problems. In face of this challenge, this study aims to investigate the effect of visualization tool-supported online problem-based learning on medical students' clinical diagnostic expertise development. Methods A controlled study was conducted and 52 medical students were randomly assigned into experimental group (using visual-ization tool-supported online PBL environment for learning) and control group (using online PBL envi-ronment for learning without visualization tool support). Participants were asked to complete the diag-nostic analysis of three kidney problems according to the requirements of the learning environments and to provide feedback of online learning experience afterwards. Paired-sample t test and one-way analysis of vonriance were used to analyze both group's case 1 and case 3 on line learing scores. Results The results revealed that the experimental group had significant improvement in online learning performance [case 1: (1.47 ±0.54), case 3: (2.14 ±0.55), P=0.015], while the control group had no significant improvement [case 1:(1.57±0.67), case 3:(1.66±0.49), P=0.234]. Early performance of online learning and group factor had interative effects (F=7.266, P=0.013). Conclusions The findings suggest that visualization tool-supported online PBL environment can facilitate medical student clinical diagnostic expertise development effectively.
