McREL Research Study

Updated 7 months ago by Mackenzie Maddox

McREL International conducted evidence-based research and used a quasi-experimental (matched comparison) design that conforms with the requirements of the Every Student Success Act (ESSA) evidence standards for providing Tier 2 Moderate Evidence. The outcomes of interest were grade-level gain (from third to fourth grade) on the mathematics and reading scales of the State of Texas Assessment of Academic Readiness (STAAR) assessment. Achievement gain of Education Galaxy user schools was compared to gain of non-user schools from 2016-17 to 2017-18 school years, controlling for prior achievement and other school-level demographic variables to ensure baseline equivalence of the two groups. Schools in the study utilized Education Galaxy and Liftoff programs and answered a minimum number of questions based on recommended usage levels.
