Miao, Y., Burgos, D., Griffiths, D., & Koper, R. (2007). Representation of Coordination Mechanisms in IMS Learning Design to Support Group-based Learning.
Group interaction has to be meticulously designed to foster an effective and efficient collaborative learning. IMS LD can be used to represent group interaction formally and then the formal model can be used to scaffold group interaction at run-time. In this chapter, we investigate the expressiveness of IMS LD in representing coordination mechanisms by using coordination theory as an analytical framework. We found that IMS LD can represent almost all the basic coordination mechanisms. We also found some hurdles to be overcome in representing certain dynamic coordination mechanisms. According to coordination theory, common coordination mechanisms can be reused in different settings. We briefly explore the feasibility of representing coordination mechanisms at a high-level of abstraction and then automatically transforming the abstract description to computational coordination mechanisms represented in IMS LD.
