Knowledge structures are often represented in the form of networks or maps of concepts. The coherence and connectivity of such knowledge representations is known to be closely related to knowledge production, acquisition and processing. In this study we use network theory in making the clustering and cohesion of concept maps measurable, and show how the distribution of these properties can be i...

To enhance collaboration opportunities in this situation, KA provides information about the activities of the learners within the shared knowledge space. For instance, the messages are “someone is looking at the same knowledge that you are looking at,”...
