Towards a methodology for educational modelling:a case in educational assessment

Educational modelling is the modelling of educational [sub-] systems. Such a model is a framework containing important concepts, processes and relations. Several models have been published but their development, which we call educational modelling, still is a tedious process. We lack clear guidelines or a methodology. In this article we present a case study in which we take first steps towards the development of a methodology for educational modelling. We do so by analysing our current practice that we typify as expert-driven, model-centred and consensus-based. We explicate the assumptions under this approach and investigate whether these assumptions are explicit and confirmed by our case study. The results give rise to a number of guidelines that can be used by future projects and that provide a first step towards a more systematic approach to educational modelling
