Issue addressed: Problem-based learning (PBL) is a student-directed pedagogy that promotes critical thinking, self-directed learning and communication skills essential for health promotion students and practitioners. This paper reports on student results, student evaluation and staff experience of PBL in the face-to-face and fully online environment in an undergraduate health sciences unit in an Australian university.Methods: A single time-point study using quantitative and qualitative administrative student data (2014-2020) and narrative reflection from teaching academics (n = 5) was undertaken. Descriptive, independent t test and bivariate analyses for student results data were conducted; an inductive approach was used to analyse qualitative data and create codes.Results: Student sample (n = 472) consisted face-to-face (n = 358, 75.8%) and online (n = 114, 24.2%) enrolments. Final Unit Mark was significantly higher for fully online students compared with face-to-face students in 2018 (P = .007) and 2019 (P = .001).
