O presente estudo analisa a prÃtica pedagÃgica da educaÃÃo sexual em duas escolas de ensino fundamental no municÃpio de Floriano-PI. A seleÃÃo das escolas se deu mediante os seguintes critÃrios: ser uma de natureza pÃblica e outra particular; possuir ensino fundamental de quinta a oitava sÃrie, nos turnos manhà e/ou tarde; possuir em seu quadro funcional, alÃm do professor de ciÃncias, outros que trabalhem a educaÃÃo sexual. A pesquisa à qualitativa, do tipo estudo de caso. Professores e alunos foram entrevistados no intuito de melhor caracterizar essa prÃtica educativa. Com esse estudo, conclui-se que as escolas pesquisadas desenvolvem dois tipos principais de educaÃÃo sexual: uma oculta e outra explÃcita, com abordagens mÃdica, pedagÃgica e polÃtica. Os professores demonstram maturidade e entendimento de suas limitaÃÃes e de possibilidades de concretizar a educaÃÃo sexual como prÃtica educativa escolar. E, ainda, concebem a escola como um local ideal para esse exercÃcio pedagÃgico. No entanto, hà consenso apenas que pessoas devidamente capacitadas devam exercÃ-la. Para os alunos, a educaÃÃo sexual à importante e se faz necessÃria por fazÃ-los refletir. Todavia, a falta de integraÃÃo e de sistematizaÃÃo dos conteÃdos abordados, dentre outros fatores, sÃo os que fazem com que a educaÃÃo sexual aconteÃa de forma ainda frÃgil na realidade estudada. Como protagonistas dessa realidade, os prÃprios alunos sugeriram a educaÃÃo sexual que gostariam de ter na escola; contudo, cabe aos educadores repensarem as possibilidades institucionais da escola, repensar o processo burocrÃtico, percebendo-o como uma forÃa capitalizadora da unidade e, portanto, uma questÃo polÃtica e nÃo apenas funcional. / The present study is a qualitative case study research, which aims to analyze the pedagogic practice of sexual education in two schools of elementary teaching in Floriano, state of PiauÃ. The selection of the schools was done by the following criteria: one school must be a public school and the other one must be a private school; both of them must be elementary teaching schools, teaching from 5th to 8th grade, with morning and/or afternoon sessions; both schools must have a sexual education teacher in its staff in addition to the Science teacher. Teachers and students were interviewed with the intention to characterize better the educational practice. Through this study it is possible to conclude that the researched schools develop two main kind of sexual education: an occult one and an explicit one, with medical, pedagogic and politic approaches. The teachers show maturity and understanding about their limitations and possibilities of realizing sexual education as an educational practice of the school. Besides, they conceive the school as the perfect place for that pedagogic exercise. However, they agree that only properly qualified people should exercise it. For the students, sexual education is important and necessary for making them reflect about it. Nevertheless, the lack of integration and systematization of the approached contents, among other factors, makes sexual education happens in a still fragile way in the studied reality. As the main characters of that reality, the students themselves suggested what sexual education they would like to have at school. Yet, it is up to the teachers to ponder about the institutional possibilities of the school and to think over the bureaucratic process perceiving it as a capital force of the unit and, therefore, a political and not only functional subject.
