The present master thesis deals with the presentation of a variety of modes of life, and thus with awareness traning for pupils at secondary level I and II on homo-, bi- and transsexuali-ty/transgender. In the first part of the thesis, a theoretical discussion is carried out, the se-cond part shows the empirical investigation. The empirical investigation was operated with a qualitative and quantitative method triangulation. The students' attitude towards homosexu-ality should be made clear. In cooperation with the Association Rosalila PantherInnen, the study was carried out as part of the awareness training at Styrian schools, where a partici-pant observation and a questionnaire questionnaire were held. The results show, on the one hand, that the students have little or no prior knowledge of homosexuality, which can mean that homosexuality is still treated as a tabuthema by the schools and the parents' home. In homosexuality, there are also significant differences between girls and boys, with the girls showing greater acceptance. Another striking result is that many of the respondents' homo-sexuality is more associated with being gay than with lesbian being. This forgetting of the lesbians, has already been shown in other studies of homosexuality and is ultimately a further form of discrimination.
