The ability for students to understand numbers and other mathematical symbols is a crucial part of success in mathematics. Accordingly, it is important for researchers to understand the nature of symbolic number processing -- the connections between a symbol or collection of symbols that convey numerical information (e.g., Arabic digits,…

The research-to-practice gap in special education refers to educators' limited use of practices that are supported by empirical evidence. Procedures specifying criteria for the determination of evidence-based practices (EBPs) in special education have the potential to address challenges associated with identifying EBPs. Although meta-analyses and…

The purpose of this study was to examine the validity of two widely used Curriculum-Based Measurement (CBM) in reading--oral reading and maze task--in relation to reading comprehension on state tests using a meta-analysis. A total of 61 studies (132 correlations) were identified across Grades 1 to 10. A random-effects meta-analysis was conducted…

A quantitative meta-analysis research study was undertaken to analyze literature on teacher perceptions regarding the use of technology integration from 2002 to 2012. During this time period, technology applications were developing at a fast pace and skills in technology use were increasingly required in the workplace. In response, schools began…

An increase has occurred in the number of students identified as having high functioning autism (HFA), who are being served in the regular education setting with their non-disabled peers. Many of these students have difficulty with academic and social expectations in this setting, and a minimal amount of information is available to educators…

This research is an examination of the instructional leadership practices of effective rural superintendents who oversee school districts in small, rural school districts in the most northern New England states of Maine, New Hampshire, and Vermont. The study looked at the successful leadership practices of school district superintendents who have…

Intelligence tests and adaptive behavior scales measure vital aspects of the multidimensional nature of human functioning. Assessment of each is a required component in the diagnosis or identification of intellectual disability, and both are frequently used conjointly in the assessment and identification of other developmental disabilities. The…

The purpose of this meta-analysis was to examine the effectiveness of early numeracy interventions for young students, including students with disabilities or those at-risk for mathematics difficulty (MD). This study evaluated preschool, kindergarten, and first-grade interventions on early numeracy content, instructional features, and…

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disability characterized by symptoms of inattention, hyperactivity and impulsiveness, which may cause impairment in a variety of cognitive, social, behavioral, and emotional domains. Extensive research has been conducted to determine the best course of treatment for…

In the current document, an integrative CBT-TTF framework is created, which proposes: technologies that require large amounts of working memory are best at improving outcomes that require little working memory to develop, and vice versa. Then, a meta-analysis of virtual reality (VR) training programs (which require great amounts of working memory)…

In contrast to Early Intensive Behavioral Intervention (EIBI), there are far fewer meta-analyses evaluating Naturalistic Developmental Behavioral Interventions (NDBIs) (Schreibman et al., 2015). Indeed, Pivotal Response Treatment (PRT)--a prominent NDBI--lacks meta-analytic studies. In the context of developing a line of research on the…

This dissertation examines the role of conceptions of data's value in data practices. Based on a study of three small teams of scientists carrying out ecological research at a biological station, my study addresses the following main question: How do scientists conceive of the value of their data, and how do scientists enact conceptions of value…

Despite decades of research supporting family engagement's benefits on children's social, emotional, behavioral, and academic development (Hill & Tyson, 2009; Jeynes, 2012; Patall et al., 2010; Sheridan et al., 2010), teachers are not always adequately prepared to work with families (Chavkin & Williams, 1988; Epstein & Sanders, 2006;…

How parents interact with their children impacts many crucial facets of children's lives. Over the last 4 decades, researchers have identified four different parenting styles: authoritative, authoritarian, permissive, and disengaged. Hundreds of studies conducted all over the world, have identified correlations between parenting style and many…

This meta-analysis synthesized the findings from 23 published and five unpublished experimental or quasi-experimental group design studies on word problem-solving instruction for K-12 students with learning disabilities (LD) and mathematics difficulties (MD). A secondary purpose of this meta-analysis was to analyze the relation between treatment…
