A multi-touch ER diagram editor to capture students' design rationale

The increased presence of diagram-type student work in higher education has recently attracted researchers to look into the automation of diagram marking. Research into the semi-automatic diagram assessment at Loughborough University has identified the requirements of a diagram editor in order to capture the students’ design rationale. To fulfill these requirements, several experimental diagram editors have been developed. This paper introduces an ER diagram editor which uses multi touch technology. The initial experiments and findings for the editor are described in the paper.
