The increased presence of diagram-type student work in higher education has recently attracted researchers to look into the automation of diagram marking. In order to capture students’ design rationale the research team working on semi-automatic diagram assessment at Loughborough University has identified the requirements of a diagram editor. To realise these requirements, several experimental diagram editors have been developed with differing interfaces. This paper introduces a gesture-based diagram editor for database conceptual models. This editor is an improved version of an early prototype editor, and supports two new context dependent gestures. Initial experiments show that the students are pleased with new gestures and the editor.
