The demands on future engineers as well as objectives of the Bologna Process call for rethinking teaching methods in engineering sciences. Furthermore, attracting more young people, particularly young women, into Engineering Education, is a key-element in contemporary Higher Education. Universities and schools will have to face these challenges, in living up to the requirements of change processes in a sustainable manner. Against this background this paper presents a teaching and learning approach in Engineering, which focuses on integrative enhancement of students´ specific and personal competencies and on strengthening school-university networks. The theory-based concept, its curricular implementation and empirical findings of the complex efficacy analysis are presented.
