Leveraging students' programming laboratory work as worked examples

This paper describes a web-based courseware that is designed to further improve the programming skills of strong students. The courseware leverages students' laboratory work as worked examples. Worked examples are regarded as an efficient tool for schema acquisition. The variations in the methods used in the examples provide an opportunity to acquire alternative schemas for solving problems. The paper describes the functions of the courseware. The results of the evaluations suggest that students' solutions are intrinsically useful as worked examples because they exhibit significant variations.
