The following simple scenario demonstrates 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.
Students log in with a lecture password. You can log in with any mobile device as smartphone or netbook. Javascript should be activated.
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,...)
After all participants have decided, the lecturer gets an instant result and can discuss it with the participants of the lecture.
