  1. Table 3 summarizes the main results regarding the individual factors examined and is divided into four parts. The upper left part presents the cross-sectional findings without controlling for random effects. The lower left part presents the over time change results without controlling for random effects. The upper right part presents the cross-sectional findings after controlling for random effects at Levels 2 (individual) and 3 (Classroom). The lower right part presents the over time change results after controlling for random effects at Levels 2 (individual) and 3 (Classroom). Controlling for random effects mildly differentiated the results, and therefore, only the results after controlling for random effects were considered and reported in the text (right side of the table)
