In this study, we tried to investigate the efficiency of using the RPG “A saga da Fisica” (The Saga of Physics) as a teaching strategy in History and Epistemology of Physics subject in the TT Physics undergraduate course at a private university in Southern Brazil in 2012. It was intended that students immerse themselves deeply into the RPG reality layers and correlate their internal motivations with the historical characters’ motivations so that they experienced the grounds of scientific discoveries, each in its own time, providing students with the opportunity to clarify their positivist and linear perception of the History of Science. At the end of the sequence of episodes, a questionnaire containing closed and open questions about their impressions was applied to the 15 students enrolled. An analysis of the students’ answers suggests that the goals above have been partially achieved.
