Self-motivation has greater impact on student learning compared to the home and school. The various means of enhancing self-motivation of individual students merit investigation. One means of increasing self-motivation is by giving students clear benchmarks or criteria by which they can judge their own performance in assessment tasks. Sometimes these criteria refer to qualities and other times to specific standards that should be achieved when a task is assessed. This presentation is of a case study which illustrates the usefulness of assessment criteria on individual performance. The underlying assumption of this case study is that if assessment criteria are embodied in the planning of learning, students can be guided on how to improve their performance.
