This paper presents new teaching materials on conflict management regarding to mediation subject involving gender, stereotypical and generation conflicts through the development of three-party role play simulation plus detailed instructions and teaching notes regarding Brazilian civil engineering environment as scenario. The case was designed to develop and encourage the dissemination of Mediation skills among students, through a simulation that involves a young qualified female engineer in an environment traditionally dominated by men in Brazil and the challenges faced. Different types of Mediators are also employed, such as facilitating, formulating and manipulating mediators. The role play simulation is designed to: (a) to provide teachers with educational tools and new insights about how to address solutions to gender, stereotypical and generational conflicts (b) enhance students’ skills on mediation, conflict management and consensus building and (c) provoke debates in classroom regarding to changes in the Brazilian civil engineering workforce.
