When you have started a loop and you are in step 2, a pop-up window will appear. Here you will find the alternative to let your participants terminate the loop on their own when they are done.There are three different ways to do this. The first alternative lets the participants leave the loop at any given time, when they have worked with the content they themselves find relevant. The second alternative lets the participants leave the loop when they have checked off and handed in answers in all the nodes. The third alternative requires the participants to hand in answers in all the nodes and you as a teacher to have approved all their work before they can terminate the loop.
