What is a node? 

There are 10 different kinds of nodes, with different functions, where participants learn and communicate. The leader who builds the loop fills the nodes with material, such as their own texts, films and tasks and also interesting material that one can link from the internet. There are yellow nodes, where participants can only see the material, pink nodes that are self correcting quizzes, light blue nodes where the participant communicates individually with the leader and green nodes where they communicate with other participants in the loop. You can read more on the functionality of the different nodes in the article "Loops 10 nodes". You can also go to the loop Build a learning loop, in the library, to see an example of how to use the different nodes.
