Abstract
Although the use of diagrams is advocated in mathematics, support for this instructional practice appears to be intuitive rather than evidentiary. A case study was used to evaluate the effectiveness of instruction in diagram generation with Year 5 students. The results suggest that although instruction can have a positive effect on students' diagram generation, the success of the program is dependent on the teachers' understandirig of the role of diagram generation in problem solving and how diagram generation can be facilitated.
