approach (ranging between 1% - 18% in year 1 and 2% - 35% in year 2). Time spent on the Language approach did increase in year 2 for four teachers with a noteworthy increase of 31% for Ysabel. The Context and Reader approach showed equally diverse but on average less radical changes. Time spent on the Context approach increased for three teachers (ranging between 2% - 19%), decreased for four teachers (ranging between 2% - 12%) and stayed the same for Caitlin. Time spent on the Reader approach showed a similar movement: an increase in time for six teachers (ranging between 5% - 20%) and a decrease in time for two teachers (ranging between 1% - 10%).
We then calculated the deviation of the four approaches from the assumed even distribution of 25% lesson time per approach. Table 6.6 presents the deviation of each of the four approaches as well as the total deviation from the assumed even distribution. It also presents the difference between the total deviation before and after the intervention (Δ).

Before the intervention, on average, the eight teachers deviated between 15% - 35% from the assumed even distribution. This deviation was reduced after the intervention to 8% - 22%. Looking at the changes made by individual teachers, the largest change in deviation between year 1 and year 2 was made by Liz, with a reduction from 35% to 21%. The smallest difference in deviation was made by both Caitlin and Fred with 1%. Furthermore, before the intervention, Fred’s
