Grit students outperformed the control group by 21% (using a median score) or 52% (using an average score).
In the course of a month, Grit students were given the use of tablets for about 1 hour a day for a total of 18 hours. There was a control group who were part of the same class as Grit students. The students in this control group did not use tablets. Both Grit students and the control group students were given the same level of math teaching, and nothing extraordinary (eg extra classes) were given during that month. The only difference is that Grit students access math material through tablets.
Both Grit students and the control group were tested at the start of the program using a US based Common Core Grade 3 math test (this is harder than the Cambodian curriculum). This is the "baseline" score. After 20 school days, the students were tested again using a similar test (the skills tested are the same but the questions change). The scores on this test are compared with the baseline score.
The average improvement of Grit students between tests was 114%, the average improvement of students in the control group was 61%. Grit students outperformed their peers by 52%.
As there were some extreme outliers (one Grit student improved by 700%), a median score may be more representative. In this case, the median improvement of Grit students between tests was 60%, and the median improvement of students in the control group was 39%. Grit students outperformed their peers by 21%.
