The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

This report looks at student achievement levels in Arkansas school districts disaggregated by district poverty and by the district's performance relative to other districts. We estimated district performance statistics by subject and grade level (4, 8, and 11-12) for longitudinal student cohorts, using statistical models that adjusted for district…

Literature indicates that technology, including exergaming, is popular among adolescents and can be used as a supplemental tool in the physical education classroom. Therefore, the purpose of this study was to examine third and fourth grade students' perceived enjoyment and exertion levels toward exergaming in relation to traditional physical…

Student achievement in literacy and mathematics for students involved in a Spanish language program at a large and diverse school district in Arkansas, were compared to peers' scores who did not participate in the program. The program was implemented to enroll native English speaking students in a Spanish enrichment program (SEP) with the intent…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

Each state and jurisdiction that participated in the National Assessment of Educational Progress (NAEP) 2011 mathematics assessment receives a one-page snapshot report that presents key findings and trends in a condensed format. Overall results, achievement level percentages and average score results, comparison of the average score in 2011 to…

Guided by a new framework, the NAEP science assessment was updated in 2009 to keep the content current with key developments in science, curriculum standards, assessments, and research. The 2009 framework organizes science content into three broad content areas. Physical science includes concepts related to properties and changes of matter, forms…
