The design of an e- knowledge model (e-KM) and the study of its efficacy for learning surgical procedures by medical students

Universities are undergoing changes in the delivery of their curricula in an environment that is influenced by technology(1-4). The introduction of computer technologies provide a platform for teaching clinical procedures via an electronic medium allowing the observational component to be achieved more than once creating increased opportunities for learning. Purpose : Is to develop a knowledge model of a surgical procedure (cyst removal) in an electronic medium such that it would enhance knowledge acquisition of surgical skills of medical students. In order to study the efficacy of the model the cognitive aspect of knowledge acquisition was assessed. Method: The study was based on the Fits-Posner stage theory on learning motor skills. A randomized experimental study was designed. Total of 56 second year medical students participated in the study. ANOVA, regression analysis and Pearson's correlation techniques were employed to analyze data. Results: There were no significant difference between the e-KM computer model and the surgeon instructor. There was a significant correlation between access time to the video and knowledge. Regression analyses indicated that increased time on task increases test scores, thus having a positive impact on knowledge acquisition. Conclusion: e-KM provides increased learning opportunities thus having a positive impact on knowledge acquisition.
