This article describes the evaluation of an online study skills course unit designed, using evidence-based principles, to support undergraduate students. A mixed-methods approach was employed to establish the extent to which the unit was (a) fit for purpose and (b) effective. Data were obtained from an online survey (n = 63) conducted on entry to the unit and on exit several months later and from face-to-face interviews with students (n = 12). Moderate to large positive and statistically significant changes between entry and exit measures of student knowledge and confidence in a variety of study-related skills were identified in the survey data. Positive data regarding confidence were also evident in the interview data, which further revealed that, although the unit was generally seen as fit for purpose, there were some issues regarding feedback to students and the supporting face-to-face tutorials that were provided. The literature would benefit from larger-scale and more robustly designed research in this area. (Contains 2 tables.)
