This paper reports on a study which investigates the implementation of a wiki system as an additional tool to support student learning in an IT related course offered by the Open University of Hong Kong (OUHK). It focuses on a set of interview data related to the tutors' and students' views on and experience of their use or otherwise of the system in the course. The key results on the tutors' and students' participation in the wiki and factors which facilitated or hindered their use of the system are discussed. The findings indicate that the extent of training provision, the wiki pedagogy and participants' readiness for and awareness of their roles in a collaborative online learning environment are major factors affecting the effective use of the wiki. The add on nature of the wiki in this study also caused workload and motivation problems for the participants. Based on the results, strategies are suggested for implementing wiki based learning in both the OUHK and the wider academic context. (Contains 1 table.)
