Abstract:The purpose of the research in to investigate, using apos (Actions, Processes, Objects and Schemes) theory, mental constructions of college freshman students—proposed as a case study-show on the construction of the concept of probability. The overall structure of the study is based on the methodological cycle provide by same theory apos, designing a genetic decomposition from a historical-epistemological of the concept, study which is tested through a questionnaire applied to the case. The results indicate that some of the students, who responded to the questionnaire, reach to the construction of the concept of probability, which proves the validity of the genetic decomposition construction proposed as a model of the concept in question.
