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:

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.

Overview of Student

Shows what items a Student is has linked their item to. Can be used to track progress.

Learning path

The complete path to an item (here: Virtual Cameras) and what's next.

NOTE: Color coding was currently not possible for this specific case.

Course Work
