Mediated Chat 2.0, Embedding Coordination into Chat Tools

Abstract. This research project investigates the coordination of debates using chat tools. In order to evaluate the Mediated Chat 2.0 tool, which implements coordination mechanisms to facilitate the application of group conversation techniques, debates were held during a distance education course using the AulaNet learningware. The logs were analyzed to evaluate how appropriately the proposed mechanisms helped during the coordination of the chat

Supporting student team project work : the Guardian Agent system

The research presented in this thesis investigates student team working, by designing, implementing and evaluating a prototype software system, as an aid for co-located students carrying out their team project work. In higher education team projects are a good way for students to put theory into practice and gain experience of team working, by working collaboratively. But difficulties often arise during the projects, which prevent students from benefiting fully from the experience. Some difficulties are known to arise in organisational teams, and others are unique to student teams, but the getting started stage is crucial for developing team cohesion.Technology tools are used to support the task oriented roles of team working, but there is little support for students to get started on their team projects, and to develop a shared understanding. This prototype system provides a function for allocating tasks of the project to appropriate team members and a function to help the team to agree ground rules for team working.A case study approach was adopted for this research, and the prototype system was developed over three cycles, amending the system according to student feedback. At the end of the study, data obtained from the students was analysed to find out how useful the online support system was for helping the student teams to get started on their projects.The students in this case did benefit from the functions this system provided, in particular the team leaders used the output to help plan their projects, and output from the system contributed to team cohesion through developing a shared understanding between the team members. These students recognised the potential of the system for helping students working on team projects online, and gave suggestions for modifications to the system that could be incorporated in further development of the system
