Abstract

In this paper, we describe the advances we have made in extending the quiz component of our VLE (Moodle) to support the drawing and automatic assessment of free-form diagrams. The paper illustrates how diagram-based questions are incorporated into normal Moodle quizzes and the nature of the feedback provided. It describes the types of diagrams that can be supported by the system (graph-based) and outlines how the automatic marking is performed. We briefly summarise the results of our tests of the marking algorithm which show that it performs well. Finally, the paper outlines two important support applications: one for specifying the type of a diagram to be used in a quiz and one for creating questions, model solutions and marking schemes for diagram questions.
