The use of case studies to teach materials science undergraduates is an exciting and interesting educational approach. As well as helping learners to connect theory and practice, the case method is also useful for creating an active learning environment, developing key skills and catering for a range of different learning styles. This paper explores the case-based approach and gives details of how they have been integrated into a number of degrees in the Metallurgy and Materials Department at the University of Birmingham. The evaluation of the case studies is also discussed along with the consequent actions and development. (Contains 3 tables.)
