Why? When an otherwise successful intervention fails

摘要

Problem-Based Learning (PBL) has been an effective technique in developing self-directed learning and problem-solving skills in students --- especially in the medical school environment. This paper looks at some preliminary results of an ethnographic study of students in a software development environment trying to use PBL. Our findings indicate that students need explicit training in group dynamics, students tend to rely excessively on existing knowledge, and they focus almost solely on product-related issues versus process-related ones. We then present some suggested improvements and future planned research.
