The piecewise latent growth models (PWLGMs) can be used to study changes in the growth trajectory of an outcome due to an event or condition, such as exposure to an intervention. When there are multiple outcomes of interest, a researcher may choose to fit a series of PWLGMs or a single parallel-process PWLGM. A comparison of these models is…

This study examined group differences in online reading comprehension (ORC) using student data from the 2016 administration of the Progress in International Reading Literacy Study (ePIRLS). An explanatory item response modeling approach was used to explore the effects of item properties (i.e., item format, text complexity, and cognitive…

To explore the wider educational environment included in the dynamic model of educational effectiveness, this paper reexamines the association between student achievement and two national culture dimensions: Monumentalism-Flexibility and Collectivism-Individualism. Using Programme for International Student Assessment (PISA) 2018 data of 317,127…

Reading research in the United States has mainly focused on early or, less frequently, middle grades and on monolingual (MN or English-only) rather than on multilingual (ML) students. To address these gaps, we focused on factors contributing to high school ML students' reading achievement. In particular, we first used machine learning to identify…

Physical activity can meaningfully influence educational outcomes. However, physical activity among youth remains insufficient (World Health Organization, 2018).Youth who are not physically active are more likely to encounter chronic health issues including obesity, depression, and anxiety (Bartelink et al., 2019, Bélair et al., 2018, Krebs,…

It is known that the reading performance of disadvantaged students is lower when compared to non-disadvantaged students. It has always been discussed that being disadvantaged affects teachers' bias in scoring students' reading performance. Therefore, the existence and effect of the teacher factor in the low level of reading performance of students…

This quantitative study explores the success rate of middle school students who chose to participate in virtual learning during the 2020-2021 school year. Students were provided access to the internet and Chromebooks and had attendance requirements within the program. Families that chose the virtual learning option agreed to give the students…

This causal-comparative study analyzed third grade reading scores from the National Center for Education Statistics, Early Childhood Longitudinal Study (ECLS) K-2011, by one of five school types, and four U.S. geographical regions. Forty-one of 50 states were represented. The problem studied is the unexplained elementary reading performance…

This quantitative study aimed to examine the relationships between third grade reading instructional strategies in high-performing Title-One schools compared to low-performing Title-One schools in four school districts in South Carolina. The study was framed through the lens of Marzano's Theoretical Framework which outlined specific instructional…

The Institute for Multi-Sensory Education's (IMSE) mission of "empowering districts, schools, teachers, and parents to be agents of change toward equitable literacy instruction for all learners that is driven by research" is reflected in the organization's structured literacy approach to the Orton-Gillingham (OG) curriculum and their…

The reading achievement gap between Black and White students was 29 points in Florida, depicting an alarming eight-point increase over that of the United States. Within School District A, the reading achievement gap was over 40% for over 4 years resulting in a district-wide plan for reconciliation and to determine the contributing factors of the…

The purpose of this study was to investigate the differences in the reading assessment performance between Black male students and their same grade level counterparts. Assessment results and teacher perceptions were analyzed to reveal instructional supports to demonstrate reading achievement. The mean scores and pass rates based on race and gender…

This dissertation consists of two chapters that examine the impact of educational and positive youth development programs on students' academic and behavioral outcomes. In the first chapter, I evaluate the effect of the Community Eligibility Provision (CEP) program, a school meal provision allowing schools meeting the eligibility requirements to…

Students' academic motivation has been highlighted as one of the most significant and malleable factors that influence their academic behaviors, college major and career choices, and academic performance. The AIR National Assessment of Educational Progress (NAEP) research team has conducted four studies focused on the role of motivation, relating…

The OECD Programme for International Student Assessment (PISA) examines what students know in mathematics, reading and science, and what they can do with what they know. It provides the most comprehensive and rigorous international assessment of student learning outcomes to date. Results from PISA indicate the quality and equity of learning…
