This document discusses the use of role play activities in an ESL Spanish university classroom. It begins by noting that students are unused to speaking English and are afraid to participate. It then explores using role plays to improve oral communication skills. Role plays allow students to feel protected in small groups and share mistakes. Examples are provided of guided role plays, where students follow scripts, and non-guided role plays, where they improvise. Non-guided role plays promote creativity, teamwork and motivation but require more preparation. Overall, role plays create a relaxed environment where mistakes are accepted and students are fully engaged.
