Students with intellectual disability (ID) have been participating in statewide general and alternate reading assessments during the past two decades. However, these students' reading performance on statewide assessments over time has not been adequately examined. The purpose of this study was to examine the relationship between students with ID's…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

Copying a text quickly and accurately is important both in school and in daily life. However, this skill has never been systematically studied, either in children with typical development (TD) or in children with specific learning disabilities (SLD). The aim of this research was to study the features of a copy task and its relationship with other…

The purpose of this observation study was to identify vocabulary instruction provided to students with Learning Disabilities (LD) and English Learners with LD (dual identified) across seventh and eighth-grade inclusion and self-contained English language arts, science, and social studies classes. The study focused on the amount of time observed on…

According to music educators, persistence beyond a student's initial enrollment in middle and high school music is a problem; however, there has been little research to substantiate this claim. Although several recent large-scale, longitudinal studies of initial selection into music classes have been conducted, longitudinal studies on who…

This dissertation researched the scope of mathematics achievement disparities in the United States and how these disparities can be minimized through a self-efficacy lens. To answer pertinent research questions with data from the National Assessment of Educational Progress (NAEP) 2019 mathematics assessment in Grades 4, 8, and 12, gap analyses,…

A growing body of research demonstrates that school climate is associated with adolescent mental health. Much of the extant literature have focused on identifying risk factors for adverse mental health outcomes, whereas much less work has been done examining factors that are important to foster adolescents' strengths and thereby increase the…

Academic underachievement, as measured on standardised assessments, is commonly reported among students on the autism spectrum. However, little is known about the factors that predict academic (under)achievement, limiting the development of effective and targeted interventions. This study explored teacher ratings of academic skills and enabling…

Dysgraphia, a specific learning disability, impairs legible and automatic letter production by hand, which can interfere with written composing. The goal of the current study was not to investigate effective methods for teaching self-regulated writing to students with dysgraphia, but rather to investigate their self that is involved in their…

This study aims to understand the role that reading motivation plays in middle school reading achievement (including achievement gaps) by analyzing the 2015 grade 8 NAEP reading data. The study focuses on identifying the unique effects of student-level reading motivation and aggregated school-level mean reading motivation on reading achievement.…

Dysgraphia, a specific learning disability, impairs legible and automatic letter production by hand, which can interfere with written composing. The goal of the current study was not to investigate effective methods for teaching self-regulated writing to students with dysgraphia, but rather to investigate their self that is involved in their…

Many adolescents struggle with reading comprehension, despite an emphasis on reading instruction over recent decades. Evidence suggests that informational text is particularly challenging for students. To implement assessments within a multi-tiered framework, schools must have psychometrically adequate tools. Using data of 473 students in Grades 6…

Bullying is grounded in the interactions between an individual and complex social-ecological systems. Therefore, bullying involvement is not just confined to the classroom or school. Recent research suggests that sibling aggression may be a predictor for peer-level aggression. These findings may be more relevant for students with disabilities…

Legislation mandates that students with disabilities be included in achievement testing for accountability purposes, with only a few participating in an alternate assessment (Individuals with Disabilities Education Improvement Act [IDEA], 2004). The current study utilized data from the Special Education Elementary Longitudinal Study (SEELS) to…

We sought to identify which kindergarten children are simultaneously at risk of moderate or severe symptomatology in both attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) as adolescents. These risk factor estimates have not been previously available. We conducted multinomial logistic regression analyses of multiinformant…
