The process of formative assessment in universities has the potential to engage students in reflection and to take greater ownership of their learning. We report on a study involving 104 students taking a statistics course in a degree programme in rehabilitation science in Hong Kong. The assessment strategy was redesigned to include a weekly online formative assessment activity for 10 weeks. In this case, it was observed that there was a high participation rate across weeks. An end-of-course online survey was conducted to explore the learning experiences during formative assessment of the cohort, and students reported high satisfaction with the process, particularly how this contributed to a change in their learning approach. Students not only showed regular commitment of time on tasks but also took active steps to find answers for themselves and with their peers.
