Common lesson motifs. The most common motifs for both grades are listed here. For each grade, the first row lists the most common length-3 motifs that do not significantly extend to other variables and prevalence r gives the fraction of lessons in which the paths are present. The second and third rows present length-4 motifs. Motifs with broken arrows indicate the possible terminations of a common stem of three indicators. For these motifs we show r for each possible ending adjacent to the final node together with the total prevalence of all alternatives.
