At a German university of technology, a large-scale project was funded as a part of the "Quality Pact for Teaching", a programme launched by the German Federal Ministry of Education and Research to improve the quality of university teaching and study conditions. The project aims at intensifying interdisciplinary networking in teaching, promoting student engagement and motivating students to take a degree in science, technology, engineering and mathematics. We describe the new teaching projects psychology students were admitted to and how many psychology students were reached. We discuss the results and outline limitations concerning evaluation in a practical setting.
