"Networks identify productive forum discussions" is published online this month in the journal Physical Review Physics Education Research, a publication of the American Physical Society.

Gavrin is studying the forums in collaboration with Adrienne Traxler of Wright State University and Rebecca Lindell of Tiliadal STEM Education Solutions. They found that when the online forum showed denser collaboration networks, the students who were most central in the network were more likely to achieve a higher final course grade.
