Employing Zearn Math usage metrics and administrative data from the Louisiana Department of Education, the results indicate that grade levels that programmatically used Zearn Math scored, on average, about .03 standard deviation units higher on Louisiana’s statewide math assessment. A placebo test using English-language arts scores and several robustness checks suggests that this may be an underestimate of the true effect. These findings come at a crucial time because pandemic-related school closures have led to a 20-fold increase in public school spending on Zearn-related materials between July 2019 and July 2021, and its presence continues to expand across the nation.  \nKeywords: blended learning, curricular effects, digital curriculum, mathematics instruction  \nCurriculum choice has long been touted as a low-cost, quick, and easy way to raise student achievement and to alleviate income-based achievement gaps (Boser et al., 2015) . Some researchers have even argued that a substantial share of the gap in math performance between economically advantaged and disadvantaged students is related to curriculum inequalities (Schmidt et al., 2015) . As such, states such as California, Louisiana, Tennessee, and others have made it part of their primary academic strategies to provide teachers with high-quality instructional materials. Many of these states have allocated immense resources to vet instructional materials through rigorous review processes to support administrators in their selections. However, these reviews and rankings are often based primarily on alignment with the state’s content standards rather than on instructional quality or efficacy in improving student outcomes. Moreover, research on curriculum adoption processes indicates that administrators rarely consider external evaluation sources when making their selections (Polikoff et al., 2020) . This could be due, in part, to the fact that rigorous efficacy studies on specific curricular materials are scarce (Koedel et al., 2017), making it challenging for administrators to make holistic decisions based on both alignment and effectiveness.  \nResearch pertaining to technology-based curricula is even more limited despite a drastic shift in the curriculum market toward digital resources (Otten et al., 2019) . Nearly half of the 12 elementary math curricula that have been reviewed by EdReports now have a comprehensive digital offering, including enVision Math, Eureka Math, HMH Into Math, i-Ready, and Zearn. Of these five, the What Works  \nClearinghouse—a repository of education research—only lists efficacy studies for three, and none of those studies were conducted recently enough to reflect the relatively newly developed digital formats ofthe curricula. Instead, the limited studies that do exist on these programs tend to be developer-commissioned studies, which may suffer from publication bias or lack external validity (Wolf et al., 2020) .  \nThis study aims to alleviate this gap in the literature by independently evaluating one such technology-based elementary math curriculum, Zearn Math. Despite its recognition on several states’ lists of high-quality instructional materials, Zearn Math has not yet been subjected to a rigorous test of its impact on student achievement. This work also contributes to the larger body of literature on blended learning—a pedagogic approach that combines teacher instruction with digital learning—which suggests t","cbCairAAoKCarPiH","https://ap.wps.com/l/cbCairAAoKCarPiH","pdf",1494250,"English","# Background\n## COVID-19 and blended learning context\n# Study design and evaluation\n## Data sources and learning metrics\n## Results and placebo/robustness checks","[{\"question\":\"What question does the study investigate about Zearn Math?\",\"answer\":\"It examines how using Zearn Math affects third to fifth grade students’ mathematics achievement in Louisiana.\"},{\"question\":\"What data and methods are used to estimate the program’s impact?\",\"answer\":\"The study uses Zearn Math usage metrics together with administrative data from the Louisiana Department of Education, complemented by placebo tests and robustness checks.\"},{\"question\":\"What do the results suggest about the program effect size?\",\"answer\":\"Grades that programmatically used Zearn Math scored about 0.03 standard-deviation units higher on Louisiana’s statewide math assessment, and the placebo and robustness checks suggest this may be an underestimate of the true effect.\"}]","Measuring the Efficacy of Zearn Math in Louisiana | PDF",1792069157,48]
