Large group settings, which often mean less peer to peer interaction among students, are increasingly common in many UK universities. This paper proposes group role-play as one possible teaching method in a large group of students, and aims to evaluate how it affects peer to peer interaction and its perceived learning benefits. The findings suggest that group role-play does encourage interaction between students and facilitates their understanding of the applicability of theories to practice. However, this study also found that group role-play should be mixed with a lecture, and that the tutor has to pay attention to time management and the motivation of a student to get involved
