Students were able to create relations between nodes and help connect the concepts they learned to concepts other students learned. Immediately following S9's creation of the node "Eliminating Confounders" on March 15, 2020, S9 then linked it to a concept discussed in this node, "Randomized Controlled Trials (RCT)." This shows how students were able to connect the concepts they learned with concepts others learned because the system allowed them to make relations between the nodes.

The system also allowed others to make improvements on others' nodes, allowing for others to add more information and help clarify misconceptions. This was showcased when S9 was able to immediately make a change to improve their own node, as described above, and then later when S10 added the method "front-door criterion" to the list on April 2, as the students were continuing to learn new concepts. This was also displayed when S11 restructured the node and its title on April 12 to help better categorize and specify aspects of the methods and making clearer distinctions between them, which were not initially present in the first iteration of this node.
