This document discusses the role play model of teaching. It defines role play as an educational technique where students spontaneously act out problems and analyze them. The key steps of the role play model are selecting a problem, constructing roles, casting players, briefing roles, enacting roles, and discussing/analyzing. Role play has advantages like reflecting on knowledge, developing skills, and engaging students. However, it requires guidance and may be time consuming. For role play to be successful, goals must be clear and roles should match students' willingness without being rehearsed.
