JACK

The JACK question type allows the input of program code by the participant. The response can be submitted as a file upload or online text. The data entered is then retrieved in the background by JACK and an assessment is transferred back to Moodle. This assessment is therefore time-delayed. JACK is an automatic exercise and examination system developed by the University of Duisburg-Essen.
