摘要:We describe an approach to the generalisation of tools for teaching and learning the skills associated with modelling with diagrams. The paper briefly describes the existing revision tools and our approach to automatic marking of diagrams. We report on our work to generalise both the marking algorithm and the drawing editor in such a way that revision tools can be easily generated for new domains. We also report how we have incorporated our tools into our institution’s Moodle-based Virtual Learning Environment (VLE).
