Resumen: Competitiveness is often considered an inherent value in the society in which we live, and it can be deliberately promoted in school sports. This study aims to know the competitive expressions involved in school soccer as a reflection of the formative value of the activity, through participant observation. Ten teams are accompanied during two school years. The analysis of the results shows that there are contradictions between the promotion of equitable sports learning and sports results, depending on individual skills and abilities. Children capitalize on sports rivalry as the need to win against the opponent, which generates paradoxes between the apriorisms of school sports, socialization and their learning. This study concludes with the need to promote educational awareness of pedagogically desirable learning in complicity with the participation of families and training agents.
