It has been suggested that interaction in online learning programmes promotes student-centred learning, encourages wider student participation, and produces more in-depth and reasoned discussions than traditional face-to-face programmes (Karayan and Crowe (1997) and Smith and Hardaker (2000) cited in Davies and Graff (2005: 1)). In this article, the participation rates and usage patterns by undergraduate political science students of online discussion forums are examined. The study is guided by a number of questions: (1) Are students willing to participate in online discussion forums? (2) Do students enjoy participating in such forums? (3) What discourages a student from participating in online discussion forums? (4) Is there a link between participation in discussion forums and grade performances in coursework? and (5) Does class size have an impact on forum participation rates? The study focuses on two groups of students studying introductory Irish politics courses in University College Cork, Ireland. The article considers student feedback on the use of online discussion forums, compares the level of participation with course grades, and finally presents an account of the author's reflections on the use of online discussion forums in teaching.
