This block brings a new possibility of navigation to moodle. After clicking on the minimap of the block a full screen concept map will appear. This map conatins learning activities which are connected in the sense of their semantic relations. For example: "voltage" depends on "electric charge" as well as "current" etc. These semantic relations are visualized by the navigation map. You can click the nodes to get to the corresponding learning activity.
The relations have to be set by you and can also connect learning activities of different courses. Connected courses are organized in "bundles".
Some learners may feel cognitive overloaded by the web. Doesn't matter, they can use the path navigation and get along a predefined (by you) sequence of learning activities by clicking the next and back button of the block.
If you have installed the other blocks of this set, "Learner Adaptation" and "Learner Preferences", the map will be enhanced with adaptive navigation support. The nodes will be colored red, yellow, green and gray (link annotation) to inform the learner, which learning activity is the best one to visit next. You can also choose to navigate along the adaptive path (direct guidance).
Please have a look into the docu (dasis.pdf) to get more information.
