One of the great challenges of learning design in computer supported
collaborative learning (CSCL) is to design effective interactive learning scenarios.
The task is one of the critical elements that can help to operationalise
educational affordances:
Since most educational design for skills or competence-based education (e.g.,
problem based, project-centered, case-based, etc.) tends to focus on the task,
we will focus more specifically on operationalizing educational affordances
through a critical element that affords the interaction between students: thetask. Task ownership, task character, and task control are defining factors in the
educational affording of environments. (Kirshner et al, 2004, p.54)
