When talking about diversity in the university context, in addition to the dimensions defined in the General Equal Treatment Act (AGG), age, gender, ethnic origin, religion/belief, disability/chronic illness and sexual identity are also particularly relevant: Social origin, type of university entrance qualification, educational biography, previous education relevant to studies, learning strategies, individual learning behavior, life circumstances (e.g. study financing, family obligations) are relevant.
All of these dimesions have a conscious or unconscious influence on the interaction in everyday study and work.
