A Preliminary Study of Open Learner Model Representation Formats to Support Formative Assessment

Open learner models provide a way of showing teachers and students the learning progress of a student against expectations. Creating an effective interface to present a learner model is an important part in open learner modeling. Usefulness of the learner model relies on using a clear and effective representation format to facilitate users' understanding of the information presented. In this paper, we propose a range of open learner model representation formats to display students' learning task status and achievement in terms of learning outcomes. We investigate different types of representation formats and data useful for users to inspect the learner model. An interface design prototype has been built to provide potential users with an evaluation platform that enables investigation of these aspects. The results obtained will allow us to develop a more effective new open learner model visualisation tool.
