Impact of role assignment and group size on asynchronous online discussion: An experimental study

• In Event: DDL- Techniques for Online Discussions

Short Description

A two-level factorial experiment was conducted to determine the main effect and interaction of role assignment and group size on the participation, learning experience, and achievement of asynchronous online discussion (AOD). The results showed that the simple role structure of initiator, supporter, and arguer increased the overall participation and peer interaction in AOD, while the group size of three members led to slightly better learning achievement. No significant interaction effects or role-specific effects were identified.
