This quantitative, correlational study aimed to investigate the relationships between collective teacher efficacy (CTE), its enabling conditions (EC-CTE), and student achievement in third through eighth grades in Colorado. Leveraging the theoretical foundations established by Rotter (1954), Bandura (1977) and expanded by Tschannen-Moran et al.…

(Purpose) This study aimed to evaluate the efficacy of Imagine Math by comparing the performance of program users and non-users on the NWEA MAP Growth Math assessment. (Methods) Propensity score matching was utilized to compare statistically similar southeastern U.S. charter school students who used or did not use the Imagine Math program during…

This quantitative, causal-comparative research study investigated whether school configuration has an impact on the reading performance of sixth-grade students by comparing the End-of-Grade (EOG) reading assessment Grade Level Proficiency (GLP) scores of sixth-grade students in K-8 configured schools to sixth-grade students enrolled in 6-8 grade…

This paper presents results of a score interpretation study for a computer adaptive mathematics assessment. The study purpose was to test the efficacy of item developers' alignment of items to Range Achievement-Level Descriptors (RALDs; Egan et al.) against the empirical achievement-level alignment of items to investigate the use of RALDs as the…

This project revealed the positive impact of the "SSS for SEL Success" program (SSS-SEL) on students' academics and perceived social/emotional adeptness. SSS-SEL, a new iteration of the "Student Success Skills" (SSS) program, teaches critical social/emotional concepts and strategies and was modified in this study to be…

Using a national sample of kindergarten to eighth grade students from Catholic and public schools who took MAP Growth assessments, we examine achievement growth over time between sectors. Our findings suggest that while Catholic school students score higher in math and reading than public school students on average, they also enter each school…

Montessori instructional approach closely aligns with The Science of Reading. Standardized test scores and student background data from statewide data sets were reviewed to produce empirical evidence that students instructed in reading in schools using Montessori methods and curriculum achieve results significantly higher than the state average…

Action towards planetary well-being requires more than environmental awareness, acquisition of knowledge, or technological fixes; it necessitates a sacred connection, recognizing interdependence, and an ethic that maintains dignity for all non-human beings. It requires a shift in our ecological consciousness from the dominator and exploitative…

The opioid crisis is widely recognized as one of the most important public health emergencies of our time, and an issue that is particularly acute for rural communities. We propose a simple model of how opioids in a community can impact the education outcomes of children based on both the extent of exposure to opioids in the community and the…

This brief continues ongoing research by NWEA® examining the degree to which the COVID-19 pandemic, and its associated school closures, influenced student learning. Prior research focused on math and reading and found that the pandemic's negative impact steadily accumulated during the 2020-2021 school year, with significant disparities in…

We examine the relationship between absenteeism and achievement since the onset of COVID-19. Applying first-differences models to North Carolina administrative data, we estimate that each absence was associated with a 0.0032 standard deviation (SD) decline in math achievement in 2022-23. As students averaged 3.3 more absences in 2022-23 than…

Important educational policy decisions, like whether to shorten or extend the school year, often require accurate estimates of how much students learn during the year. Yet, related research relies on a mostly untested assumption: that growth in achievement is linear throughout the entire school year. We examine this assumption using a dataset…

Propelled by accountability policies, leaders have touted data-driven decision making as a means to improve K-12 student outcomes and drive equity, as teachers analyze data to change instruction. However, many data-driven decision-making reforms have failed to challenge inequity. Melanie Bertrand and Julie Marsh's study of six middle schools shows…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction that met Curriculum Associates' recommended usage levels on mathematics achievement, as measured by the Massachusetts Comprehensive Assessment System (MCAS) mathematics assessment. This study compared mathematics achievement growth of students who used…

This dissertation analyzes data in order to answer the research question, "Do eighth grade students who have participated regularly in their school band programs for four consecutive years achieve higher scores in New Jersey's Grade Eight PARCC Assessment than students of similar ability who do not play a musical instrument?" Data was…
