RESUMO
Objective This paper aims to use components as the key factors to explore the feasibility of evaluation method about the learning effect of Web-based PBL.Methods We distributed a questionnaire to 101 students of clinical class of 2007 and 2008 grade in Guangzhou Medical University,and electronically distributed after 2 weeks.Cranach's α coefficient WaS used to evaluate intrinsic consistency reliability of the questionnaire.We applied principal axis factoring to extract components and to explain components which were orthogonally rotated by varimax.Multi-factor regression model Was simulated with key factors and the model's performance of fitting WaS tested.Results Multi-factor regression mode(WPBLSUM)=0.545 Collective collaboration capabilities+0.202 Self-learning and quest skills+0.137 linical reasoning and problem-solving capabilities+0.116 memorizing and understanding of medical knowledge.The coefficient of determination R2Was 0.998 and the corrected coefficient of determination R2Was 0.998.indicating that the model's fit results are obvious.Conclusion This paper demonstrates that using components as the key factors to simulate and assessing the Web-based PBL learning effect is feasible,which assesses the Web-based PBL learning effect well from four different aspects.
