Quantitative and qualitative analysis of student feedback on ePortfolio learning.

At the University of British Columbia, we introduced an ePortfolio assignment in the operative dentistry clinical simulation module and conducted a pilot study to explore the usefulness of ePortfolios as a learning tool for dental students. Qualitative assessments included student self-reflections on the ePortfolio experience. In the quantitative evaluation, ePortfolio learning was hypothesized as a multidimensional experience with four dimensions: 1) an ePortfolio experience is valuable for learning operative dentistry; 2) an ePortfolio is time-consuming, but overall a useful experience; 3) ePortfolio learning requires technical skills that are manageable; and 4) ePortfolio experience may be beneficial for lifelong learning. Overall, both quantitative and qualitative assessments demonstrated that students valued ePortfolio learning as a positive experience. In multivariate analyses (confirmatory factor analysis), the four-dimensional model of ePortfolio learning was confirmed. Future studies are needed to validate or revise the four-factor model of ePortfolio learning in different student cohorts.
