Persistent Interaction Analysis.
(A) Temporal Evolution of the total number of interactions in all groups. The y-axis indicates the number of interactions per group per week normalised to the value of the week when the maximum number of interactions was recorded for that group. This figure pools normalised data from all three courses available. High performing students start to interact before and keep interactions throughout the whole course. The same applies to mid performing students, although their interactions start a bit later in the course. Low performing students start interacting later than high performing ones and their interactions drop with time. The maximum values used for normalising these curves were 150, 36, 57 and 63 all, high, mid and low interactions, respectively. (B, C and D) Evolution of the % of persistent interactions (relative to the average total # of interactions of that group) per week and per student group (low, (B); mid, (C); and high, (D)) relative to the total number of interactions per group per week. Continuous lines represent the fit of a curve to the points as indicated in Methods. As can be observed, the % of persistent interaction increases as the course progresses for all groups of students. High performing students achieved a higher % of persistent interactions than mid and low performing ones.
