The Dependency Graph
At the lowest level the graph is structured by linking learning contents to its prerequisite(s) and useful resources. A student can now use these links to determine how items depend on each other, and what knowledge is required to understand a specific item.
In the end the graph turns into a big interconnected structure:
In order to make this amount of data useable, several Structure-Items have been defined to help group items into abstract categories.
For a more detailed explanation of the entire underlying structure go to GraphStructure or take a quick look at these following diagrams:
The base structure
Connection of courses
Dependencies and use
Using the Graph
The graph itself is more a database, than a tool. In order to make it usable several ideas have been devised and implemented. Here's a quick example of what is possible on site.
