1) The study evaluated the effectiveness of the MathDali program on improving the mathematics performance of 4th grade students. It found that the students' test scores increased significantly from pre-to-post testing after receiving the MathDali intervention, which included videos, games, and teacher training.
2) Analysis of difficulty indexes showed the test questions were of average difficulty for students both before and after the intervention. However, the students' overall combined scores improved from approaching proficiency to approaching advanced.
3) Comparisons of pre-and post-test scores between the two participating classes found the increases in scores were statistically significant, indicating the MathDali program was effective at improving 4th grade mathematics performance.
