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 andeffective representation format to facilitate users’understanding of the information presented. In this paper, wepropose a range of open learner model representation formatsto display students’ learning task status and achievement interms of learning outcomes. We investigate different types ofrepresentation formats and data useful for users to inspect thelearner model. An interface design prototype has been built toprovide potential users with an evaluation platform thatenables investigation of these aspects. The results obtained willallow us to develop a more effective new open learner modelvisualisation tool.
