The COVID-19 pandemic significantly impacted educational outcomes, including reading achievement in grades 3-5, particularly in schools primarily serving high-poverty communities of color. This study evaluates the 95 Phonics Lesson Library (95 PLL), a targeted phonics intervention program, in a low socio-economic status, ethnically diverse,…

This study, conducted by LXD Research, evaluates the 95 Phonics Lesson Library (95 PLL), a targeted phonics intervention program in a majority low SES, ethnically diverse midwestern school district from 2023-2024. Using a quasi-experimental mixed-method design, this study compares reading outcomes of fourth and fifth graders using 95 PLL with a…

Many initiatives have emphasized the importance of challenging students in text using readability formulas. Almost all formulas employ mean word frequency yet long-standing issues abound. Researchers question using a singular mean with a skewed variable like frequency. They also question the degree to which frequency pinpoints complex words,…

The primary goal of this study was to examine a key but understudied link between early career teachers' expectations (as outcomes) and their thinking styles (as teacher factors). A second goal was to explore whether teacher self-efficacy, discipline, and grade level would moderate this relationship. We collected self-report data from 390 school…

Graphical literacy or graphicacy is a critical component of scientific literacy. Graphs are used to integrate and represent complex sets of information requiring abstraction from perceptual experience. They form essential parts of the Mathematics and Science curriculum across school curricular stages. A key to developing meaningful pedagogic…

Vertical scales are frequently developed using common item nonequivalent group linking. In this design, one can use upper-grade, lower-grade, or mixed-grade common items to estimate the linking constants that underlie the absolute measurement of growth. Using the Rasch model and a dataset from Curriculum Associates' i-Ready Diagnostic in math in…

Online one-on-one tutoring serves as a supplementary approach to traditional classroom instruction. It has been shown to enhance personalized learning and academic performance. However, the dynamics of dialogic interactions within this educational setting are not fully understood. Thus, we present a computational analysis of dialogic interactions…

This dissertation explores the relationship between teacher experience, defined by years of service and grade span, and trust levels in educational leadership and among stakeholders within the school community. Trust is critical in fostering positive educational environments, enhancing collaboration, and ensuring the successful implementation of…

Purpose: Graphotactic regularities are statistical regularities governing orthographic systems that children are sensitive to from the start of their literacy learning. The current study observed changes in children's sensitivity to a set of graphotactic patterns across different grades in elementary school and measured the contribution of skills…

Motivation plays a crucial role in mathematical competence, with motivated students tending to perform better than those who lack motivation. Given that teachers can play a significant role in fostering student motivation, the aim of this study was to investigate teachers' influence on students' motivation to learn mathematics. Alongside the…

We examined how often teachers' targeted interventions fail in stopping bullying and to what extent this varies between schools vs. between students involved. In addition, we investigated which student-level factors were associated with intervention failure. Data were collected annually in 2011-2016 via online questionnaires and included responses…

In education, assessment helps shape teaching practices and student outcomes, as it influences how teachers perceive their roles, approach instruction, and engage with students. This study investigated 3rd-8th grade English Language Arts and mathematics teachers' conceptions of the NWEA MAP Growth assessment, focusing on four key factors: (1)…

Student absenteeism, which skyrocketed during and after the COVID-19 pandemic, has negative consequences for student engagement and achievement. This study examines the impact of the High-Impact Tutoring (HIT) Initiative, implemented by the Office of the State Superintendent of Education in Washington DC, on reducing absenteeism. The HIT…

The purpose of this study was to investigate if differences in perceived professional self-efficacy were due to various demographic characteristics for educators in a rural East Texas school district. Participants in this study were full-time teachers within the school district. The district consists of 2 elementary schools, 1 middle school, and 1…

This dissertation explored the unique experiences of general education teachers teaching in an inclusive classroom (which will also be referred to as a "mainstream classroom") with a combination of students with and without autism (which will also be referred to as "autism spectrum disorder" and "ASD"). This was a…
