Transition matrices and total phase times. The top rows show the transition matrices for the test (first row) and control groups (second row) for the first, second, third, and last 10 min of the activity. The entries in the matrices denote the total number of transitions made between the different phases for each group. Transitions with higher occurrences are highlighted with darker colors. The last row shows the total time spent in each phase by both groups for the four quarters of the activity. Colored dots show data points for each student of the test (blue) and control (red) groups. Dark horizontal lines indicate the mean values, dark-colored areas one standard deviation, and light-colored areas the 95% confidence intervals
