Abstract

This paper describes a software tool that has been developed to help students learn to produce UML sequence diagrams (SDs) in the context of object modelling. The tool, called the SD-Exerciser, developed from an earlier tool for learning about entity-relationship diagrams, presents a student with a series of questions and invites the student to produce SDs that represent the interactions for the use cases embedded in the questions. The SD-Exerciser marks each attempt at a diagram and provides several feedback perspectives on the student’s answer. A new development is the ability to check a sequence diagram for syntax errors some of which the tool will attempt to repair. The SD-Exerciser incorporates an automatic marking algorithm based on the successful ERD marker and experiments to date show that it continues to be effective in the new situation.
