Research Problem
Distributed learning teams in team-based learning situations aim to achieve organisational convergence.
However, there are collaboration problems due to mediated distance & time flexibility.

Key CSCeL concept: Collaboration AwarenessStudents’ difficultiesGroup AwarenessTime convergence
Learners’ Intentions (learning goals): Task Convergence
Users’ operations (actions/tasks): Pedagogical Usability
Step1a: Context & Learning Values

Being HumanCollaboration Awareness
Students’ difficulties: In addition to f2f Collaborative Learning difficulties, CSCeL situation adds Computer Mediated Communication (CMC) and ILE difficulties (Kirschner,
2009)
Group Awareness: understanding of the activities of others, which provides context for your own activity (Dourish & Bellotti, 1992)
Time convergence: Distributed learning teams are characterised by the degree of time flexibility and computer mediation (Romero, 2010)

If group awareness is a prerequisite for convergence then increase of group awareness will result in increase of organisational convergence and thus, collaboration awareness.

Step2: (Iterative) Design - Requirements
1CH 2DR 3E 4D 5E 6D 7RTR
The design can be defined as an individual and collective activity, finalized by a project to develop a physical and symbolic artefact. The artefact is rarely well defined in this step.
