This paper discusses the implementation of FirstClass computer conferencing for a second-year undergraduate module over the last six years which has proved challenging for both tutor and student. Asynchronous interaction has aided group collaborative work and the process of the collaboration has been made visible to tutors. Although time-consuming, much has been learned about the process of introducing computer conferencing and what can be expected. Giving students a structure has aided their online discussion and also by dividing them into groups. Emphasis is now on group work rather than the technological aspects of using this type of technology.
