What is a learning path? 

The learning paths are the grey lines that connect the hubs in the loop. Your students follow the learning paths through the loop. There can also be a loop with a central hub and several paths leading out from the hub. Then the text in the have to tell your students, what options they have and how you expect them to take on work in the loop. When a loop branches out and there are several paths to choose from there also have to be explanatory texts.
