In higher education, online discussions are an integral part of collaborative based e-Learning systems. However, there can be problems associated with current online discussion models. For example, it can be easy to set open-ended discussions which attract little participation and assessing contributions can be difficult or time-consuming. Students may not achieve the expected learning outcomes without proper structure and management in online discussions. This paper proposes a web-based environment for online discussions where the facilitator can structure each discussion according to its nature and learning requirements using already designed templates. Features include setting mandatory sections to address, assessment weighting, release dates and archiving options. Students can prepare and post their messages and responses using the discussion forum interface. The facilitator may assess students' messages, mark them and release them to other responders for review. The discussion can be automatically archived for further discussion or reference. Students should find the proposed structured online discussion model easier to follow, while the facilitator will have more control over the activity and find it easier to assess and re-use. Templates can help in structuring this process.
