Innovative learning environments such as massively online open courses (MOOCs) present interesting questions about traditional in-class, on-campus learning experiences. We previously demonstrated that in-person social networks can significantly influence student performance and retention. For example, women who know the most connected or the top students in class experience 13-15% rise in their grades relative to those who did not. Yet, key questions remain about how these networks develop and why they are effective. For example, how do in-person student networks form over the course of a semester? What do students gain from these networks? Do students cluster based on their Felder-Soloman learning styles, grades, or connectivity? How does classroom seating correlate with student performance and course evaluations? This talk will discuss our findings for each of these questions.
