The possibility to give feedback is required to improve quality of lectures. Tweedback is an online Classroom Response System enabling feedback especially for large audiences. Lecturers can choose between three different types of feedback. First, Peer Instruction is implemented for asking multiple choice questions. Second, on a Chatwall the audience asks questions and votes on them. Third, Speech Parameters of the lecturer's talk can be rated. Example parameters are “speed” and “understanding”. Users access Tweedback using their mobile devices. The system was designed as a scalable mobile web application. Parts of Tweedback are already actively used in various courses.
