Purpose: To study the performance of final year medical students, at the end of module assessments, following exposure to a web-based tutorial programme designed to facilitate critical thinking and logical reasoning. Method: Multimedia enhanced web-based tutorials based on patient oriented problems, designed to develop higher cognitive skills in students, were used as a supplement to an existing curricular programme for final year medical students attending an orthopaedic surgery rotation. We tested this intervention in a group of 163 final year medical students. Clusters of 15 students were randomly assigned either to an intervention or a control group. Students were examined for their clinical examination skills, critical thinking abilities, and specific factual knowledge based on curricular requirements. Results: Mean scores between control and intervention group were analyzed, and the intervention group outperformed the control group (Statistically Significant). Conclusion: Interactive web-based tutorial programmes can be successfully designed to develop higher cognitive skills in medical students. This results in more sound clinical decision making skills than simple noninteractive, content-rich web resources.
