The purpose of this analysis was to examine achievement gaps on fractions for very-low-performing students as a function of whether they receive inclusive fraction instruction or specialized fraction intervention and with the shift to Common Core State Standards (CCSS). In three randomized control trials conducted in 3 consecutive years, 203…

The Common Core State Standards for Mathematics will place more pressure on special education and math teachers to raise the skill levels of all students, especially those with disabilities in math (MD). The purpose of this study was to assess the effects of enhanced anchored instruction (EAI) on students with and without MD in co-taught general…

This study investigated the role of strategy instruction on solution accuracy in children with and without serious math difficulties (MD) in problem solving. Children's posttest solution accuracy was compared on standardized and experimental measures as a function of strategy conditions. Strategy conditions included curriculum materials that…

This study used a large statewide database to examine the oral reading fluency development of second- and third-grade students with emotional disturbance or learning disabilities and their general education peers. Oral reading fluency measures were administered to 185,367 students without disabilities (general education), 2,146 students identified…

Despite the high prevalence of comorbidity between attention deficit/hyperactivity disorder (ADHD) and learning disabilities (LD) or emotional disturbances (ED), few studies have examined the long-term effects of these comorbid relationships on student outcomes. We estimated the longitudinal academic, social, and behavioral outcomes in children…

The purpose of this study was to determine the efficacy of specific, individualized training for students with different levels of mathematical difficulties. Fifty-four students, with either severe or mild math difficulties, were assigned to individualized training or to a control condition. Ten students with severe math difficulties…

In this meta-analysis, the impact of writing interventions on the quality of writing produced by students with learning disabilities (LD) was assessed. Ancestral and electronic searches were used to locate experimental, quasi-experimental, and within-subjects design studies with participants in Grades 1-12 with documented LD. The effects of…

The relationship between basic oral language and early numeracy has been studied extensively, but results hardly include kindergartners' math language, which might mediate this relationship. The aim of this study was to investigate the development of basic language skills--specifically, math language and low early numeracy. Dutch children…

Stakeholders are debating the value of cognitively focused instruction for students who have not benefited from a skills-based approach. Much of the discussion, however, is occurring without recognition of research that has been conducted in the past 2 decades. In this article, we reviewed the research. Electronic databases and hard copies of…

This study analyzed the longitudinal development of occupational aspiration prestige scores over a 12-year period (Grade 8 to 8 years postsecondary) to better understand this aspect of career choice from adolescence into adulthood for people with high-incidence disabilities. A curvilinear trajectory was detected where aspirations increased during…

Promoting self-determination has become a best practice in special education. There remains, however, a paucity of causal evidence for interventions to promote self-determination. This article presents the results of a group-randomized, modified equivalent control group design study of the efficacy of the Self-Determined Learning Model of…

This experimental study reports findings on the effects from a year-long reading intervention providing daily 50-min sessions to middle school students with identified learning disabilities (n = 65) compared with similar students who did not receive the reading intervention (n = 55). All students continued to receive their special education…

Using data from the Special Education Elementary Longitudinal Study (SRI International, 2002), this study estimated reading growth trajectories in a nationally representative sample of 3,421 students with disabilities ages 7 to 17 representing 11 federal disability categories. Reading achievement in all disability categories increased with age,…

Many schools are implementing multitier response-to-intervention (RTI) models to reduce reading difficulties. This study was part of our larger ongoing longitudinal RTI investigation within the Florida Learning Disabilities Center grant and was conducted in 7 ethnically and socioeconomically diverse schools. We observed reading instruction in 20…

Educators have widely used cognitive strategy instruction to address reading comprehension deficits evidenced by students with learning disabilities. However, no one has yet conducted a review of the quality of this literature. This review applies the quality indicators advocated by Gersten et al. (2005) and Horner et al. (2005) to evaluate the…
