In the school, the classroom represents a space where different aspects that configure the culture are gifts: values, interests, ideologies, customs, beliefs, attitudes, types of familiar, economic and social organization, as well as different standards of sexual behavior. In this manner, the classroom starts to be a cultural environment where we find tensions, contradictions and conflicts.

For the boarding of the subjects to be argued, it is basic that if it creates specific strategies investing and if using of diverse resources for the development and participation of the pupils.
