Use Cases

Instant Classroom Response
Poll your students to instantly check their learning progress and comprehension. Choose from one of several question types to optimally support your lecture contents. Evaluate incoming responses in real-time and export them after the conclusion of a session.
Live Q&A in Large Classrooms
The Feedback-Channel extends KlickerUZHs functionalities far beyond a simple audience response system. Students are now able to ask questions and provide feedback directly and anonymously during the lecture. If available, a teaching assistant can directly answer questions or pin them to the separate lecturer view. After a KlickerUZH session, all feedbacks and responses will still be available through the evaluation view.
Use Cases of the Q&A Channel
Real-time Feedback
Beside the possibility to submit comments in written form, students can also give feedback on the lecture speed and difficulty through a dedicated visual interface in the feedback section. The so-called confusion barometer on the other side then aggregates the data into an easily readable format and allows the lecturer to adapt the lecture pace in real-time.
