Comparing computer-assisted learning activities for learning clinical neuroscience: a randomized control trial

Computer-assisted learning has been suggested to improve enjoyment and learning efficacy in medical education and more specifically, in neuroscience. These range from text-based websites to interactive electronic modules (eModules). It remains uncertain how these can best be implemented. To assess the effects of interactivity on learning perceptions and efficacy, we compared the utility of an eModule using virtual clinical cases and graphics against a Wikipedia-like page of matching content to teach clinical neuroscience: fundamentals of stroke and cerebrovascular anatomy.

A randomized control trial of using an interactive eModule versus a Wikipedia-like page without interactivity was performed. Participants remotely accessed their allocated learning activity once, for approximately 30 min. The primary outcome was the difference in perceptions on enjoyability, engagement and usefulness. The secondary outcome was the difference in learning efficacy between the two learning activities. These were assessed using a Likert-scale survey and two knowledge quizzes: one immediately after the learning activity and one repeated eight weeks later. Assessments were analysed using Mann-Whitney U and T-tests respectively.

Thirty-two medical students participated: allocated evenly between the two groups through randomisation. The eModule was perceived as significantly more engaging (p = 0.0005), useful (p = 0.01) and enjoyable (p = 0.001) by students, with the main contributing factors being interactivity and clinical cases. After both learning activities, there was a significant decrease between the first and second quiz scores for both the eModule group (-16%, p = 0.001) and Wikipedia group (-17%, p = 0.003). There was no significant difference in quiz scores between the eModule and Wikipedia groups immediately afterwards (86% vs 85%, p = 0.8) or after eight weeks (71% vs 68%, p = 0.7).

Our study shows that increased student satisfaction associated with interactive computer-assisted learning in the form of an eModule does not translate into increased learning efficacy as compared to using a Wikipedia-like webpage. This suggests the matched content of the passive webpage provides a similar learning efficacy. Still, eModules can help motivate self-directed learners and overcome the perceived difficulty associated with neuroscience. As computer assisted learning continues to rapidly expand among medical schools, we suggest educators critically evaluate the usage and cost-benefit of eModules.
