The evaluation has the following objectives, among others: First, it is about information on how Sportklasse is perceived and evaluated by the stakeholders (teachers, students, parents). In comparison, the results of the music class and a class without a theme/profile are used. Secondly, the question is who participates in the sports class. Thirdly, what is done in the additional sports lessons and which effects of the sports class (e.g. in comparison to other classes) can be determined. The evaluation is formative, so that the first results of the evaluation can already be reflected. Furthermore, the views of different stakeholders (students, parents, teachers) are taken into account.
