Experiences from the use of the Grimstad-model for design and implementation of educational software

The objective of educational software is to encourage the user to increase his knowledge of a specific domain. The pedagogical goals are achieved through a high degree of user control and they enforce heavy claims on the design process. A common platform for instructional designers and computer scientists to construct educational software is needed. This article outlines the Grimstad-model for design and implementation of educational software. We present some snapshots from a project in which elements of the model were used. The simulation program developed in the project shows important issues to consider when keeping reindeer. According to experiences gained from the practical use of the Grimstad-model and from giving teachers' further education courses, we propose extensions to the model.
