Physical Education seems to be one of the most expected disciplines in the week by a large part of the students during the schooling process. The fact can be analyzed from the very experience of the component that breaks with the fixity of the body, allowing other spaces of movement and reflection. However, the repertoire of gestures and corporal practices is not always valued and recognized by the school space. Such a context may lead to stiffening of ways of conceiving differences of gender, class, race, sexuality, age, motor ability, etc. Therefore, the present study had as objective to analyze how questions related to cultural differences are treated by the teachers in the classes of Physical Education of the high school in the daily life of a state public school of the RJ. The interest in investigating high school was because the teaching of Physical Education in this segment is still a subject little addressed in the area, perhaps due to the difficulty of teachers and students in overcoming the famous roll the ball class, or the feeling of failure that surrounds this segment of education marked with a strong sportive bias and decontextualization with youth culture. For the study, we chose to investigate Physical Education classes at a state school, located in the Campo Grande neighborhood, in the West Zone of Rio de Janeiro. Were analyzed the school s Political Pedagogical Project, the minimum curriculum of State Physical Education and the course plans of the Physical Education teachers. Physical Education classes were also observed and, finally, interviews were conducted with physical education teachers, directors and coordinators of the school in question. We conclude that cultural differences are perceived in the context of Physical Education classes, both as a problem to be solved, and as a possibility of recognition and respect for the other, although such issues are not explicitly recognized in current curricular proposals. We defend in this study the consideration of cultural differences as constitutive of all, and therefore a fundamental issue to be discussed in pedagogical practices, school knowledge, interpersonal relations and, in short, the school curriculum.
