Abstract (eng)
Evolution represents a topic that has the potential to connect all other areas of biology. The theory of evolution is therefore not only of great importance in the academic context, but also in schools, where it can serve as a central subject in biology. In addition to the beneficial thematic structure of the lessons it is also highly relevant for the learning processes of students. In contrast to additive learning, cumulative learning refers to the building of networked knowledge structures that enable broad understanding. This requires the step-by-step development of understanding over a longer period of time. The AHS curriculum does not focus on the topic of evolution across classes. In biology studies for preservice teachers at the University of Vienna it is a frequently recurring element. In this thesis I investigated to what extent the topic of evolution is the connecting element of biology lessons at school and thus promotes cumulative learning. A questionnaire was used to find out how AHS teachers assess their own teaching of evolution. The survey showed that, although the topic of evolution is considered very relevant by most teachers, it is hardly the central theme in biology lessons. Also, the curriculum is sometimes interpreted very differently. Therefore, despite the new curriculum, the way the topic is dealt with is still very individually dependent on the teachers. As evolution, for the most part, does not recurrently connect all other subject areas, cumulative learning is not promoted.
