Figures
In the summer semester 2011 a total of 441 courses from the lecture schedule were included. After deleting, for example, language courses and courses, which were subsequently dropped or registered by university teachers, questionnaires were issued for 391 courses.
When the Students Lectures Evaluation was closed, completed questionnaires for 361 courses (92.3% of 391) had been received. A total of 9,824 completed questionnaires were returned and analyzed, an average of roughly 27 questionnaires per course.
