Problem-Based Learning for Foundation Computer Science Courses

Abstract

The foundation courses in computer science pose particular challenges for teacher and learner alike. This paper describes some of these challenges and how we have designed problem-based learning (PBL) courses to address them. We discuss the particular problems we were keen to overcome: the purely technical focus of many courses; the problems of individual learning and the need to establish foundations in a range of areas which are important for computer science graduates. We then outline our course design, showing how we have created problem-based learning courses. The paper reports our evaluation of the approach. This has two parts: assessment of a trial, with a three-year longitudinal follow-up of the students; reports of student learning improve-ment after we had become experienced in full implementation of PBL. We conclude with a summary of our experience over three years of PBL teaching and discuss some of the pragmatic issues around introducing the radical change in teaching, maintaining staff support, and continuing refinement of our PBL teaching. We also discuss some of our approaches to the commonly acknowledged challenges of PBL teaching.
