IMS Learning Design Support for the Formalization of Collaborative Learning Patterns

Collaborative Learning Patterns (CLPs) are detailed descriptions of best practices in collaborative learning. These patterns provide a way for a representation of key aspects of CSCL (Computer-Supported Collaborative Learning) that is easy to understand by software developers. To formalize these CLPs we have focused our attention on IMS Learning Design (IMS-LD). IMS-LD provides a means of expressing many different pedagogical approaches (including collaborative learning), however we have found some limitations in reflecting learning experiences that are group-based. Although this specification supports multiple roles in a learning activity, it is not possible to specify how they are going to interact. This paper points out this deficiency and proposes an extension of IMS-LD. The process that can be followed in order to obtain a unit of learning based on a CLP is illustrated with an example.
