Disposable Content Usually a by product of some conversation/ learning activity Not intrinsically useful Without technology little, if any, of this type of content is retained Transient

Discussion Forums Discussion forums especially vulnerable Support educational dialogues, but store disposable learning content Hence, the focus of our study
The Study Attempted to create a separation between disposable and durable content using discussion forums. Discussion forum properties: Fully anonymous postings by students (staff still post under their names); Limited duration; Student summaries of discussion; Temporary (deleted after a time).
The Study Invited students to join the discussion forums Discussion Subjects- Difference between a scripting language and a programming language and the Likert Scale
Results- Posting Activity Second set of forums (student review of the first set of discussions)
Results Forum Features Number of Positive Comments Number of Negative Comments Anonymity151 Duration76 Summary82 Deletion15
