This is specially difficult for a distance education teacher who is trying to monitor the performance of his/her students. How do we know that we are spending more time on one student and forgetting others. In the preceding posts I pointed out that isolates are a good measure of triaging assistance to students who cannot keep up with the forum. Another measure may be ego networks. With it, a teacher could easily spot with which student he/she is not interacting enough with, and which student he/she is spending too much of his/her time with.
Here is a toy graph of 13 nodes to illustrate my point.
