The current research deals with the constructive revision – in the cognitive structure of first year students in a public high school state, in the Uniform Rectilinear Motion (URM) conception, evolving from the Aristotelian to Galilean thinking. Students have a natural difficulty in understanding the existence of motion without a prime mover action – a Galilean concept – since they can only observe it in complex laboratory experiments or as a result of mental idealization. Differently, the Aristotelian conception permits an easier comprehension since it can be demonstrated from the sensorial observation of everyday experiments. In this work, through pedagogical activities based in the Kelly’s Experience Cycle (KEC), part of the Personal Constructs Theory (PCT), formulated by George Kelly, examined the URM concepts, as per Galileo and Aristotle and revised basic concepts of Physics related to the research topics of concern to the students, we intend to investigate whether the KCE is appropriate for the desired conceptual revision asking the following question: how to promote, among first year students in a public high school, the revision of Aristotelian thinking introducing Galilean logic? In order to reach our objective we did a didactic intervention based in moments of Cycle. The results obtained, indicate a quantity considerable of students that change from aristotelian’s conception to galilean’s conception. At the end of the research we came to the conclusion that the KEC method is appropriate to promote a change of students’ conception
