Fractions test scores increased by 15 percent on average in an edtech study conducted by GameDesk. In the study, USC professor Michelle Riconscente watched as 122 fifth graders play Motion Math, a fractions app for elementary school children, 20 minutes a day for five days. What they found was a significant increase in test scores: “The results of this study suggest that what children learn through gameplay can help them perform better on the kinds of questions asked on state and national standardized tests,” says the research group.
