Teaching and Learning Applications Related to the Automated Interpretation of ERDs

In this paper we report ongoing work in the development of diagram interpretation and assessment applied to entity-relationship diagrams (ERDs). We report on our development of an automated marking tool and the results of two large-scale experiments with this tool. We give an overview and the results of some initial, informal, evaluation of a student revision tool that we developed as a result of our experiences working on the automated marking system.
