classEx in Teaching

To use classEx participants need a mobile device with internet connection. A projector should be available to make the experimenters screen visible for everybody.

The following simple scenario demonstrates in three steps how classEx can be used. As example you find a simple question where two groups get different private information as treatment to test the effect of this information on the decision.

1. Login

Students log in with a lecture password. You can log in with any mobile device as smartphone or netbook. Javascript should be activated.

2. Input

After the experiment was started subjects set their decision. Thereby several input types are at thand (input field, radio line, slider, buttons…). The input is checked on correctness before sending (minimum, maximum, digits,…)

3. Result

After all participants have decided, the lecturer gets an instant result and can discuss it with the participants of the lecture.
