Screen-Replay: A Session Recording and Analysis Tool for DrScheme

Approaches to teaching “Introduction to Programming” vary considerably. However, two broad categories may be considered: product oriented vs process oriented. Whereas, in the former the final product is most significant, in the latter the process for achieving the final product is also considered very important. Process oriented programming courses strive to equip students with good programming habits. In such courses, assessment is challenging, since it requires the observation of how students develop their programs. Conventional methods and tools that assess final products are not adequate for such observation. This paper introduces a tool for non-intrusive observation of program development process. This tool is designed to support the process oriented approach of “How to Design Programs” (HtDP) and is implemented for the DrScheme environment. The design, implementation and utility of this tool is described with examples.
