The problem addressed in this study is how a College Success course might reverse the trend of lower graduation rates for students with learning disabilities (LDs) who attend a Colorado institution of higher education. Students with LDs graduate at lower rates than the general population, but it is unclear how a College Success course contributes…

Current definitions of specific learning disability (SLD) identify a heterogeneous population that includes individuals with weaknesses in reading, math, or writing, and these academic difficulties often co-occur in many of the same individuals. The Colorado Learning Disabilities Research Center (CLDRC) is an interdisciplinary, multisite research…

Despite historical emphasis on "specific" learning disabilities (SLDs), academic skills are strongly correlated across the curriculum. Thus, one can ask how specific SLDs truly are. To answer this question, we used bifactor models to identify variance shared across academic domains (academic "g"), as well as variance unique to…

This study investigated the relationship between mathematics difficulties and psychopathology in a large community sample (N = 881) of youth (8-18 years of age) in the United States. The primary aims of the study were to (a) test the associations between mathematics difficulties and specific components of internalizing, externalizing, attention,…

As public schools, charter schools are legally required to educate all students regardless of the difficulties they bring with them into the classroom. Nonetheless, many are concerned that the charter sector fails to educate all comers. Charter schools are often criticized for not enrolling similar proportions of students with disabilities as are…

This study evaluated a scheduling methodology referred to as intervention-based scheduling to address the problem of practice regarding the fidelity of implementing Response to Intervention (RtI) in an existing school schedule design. Employing panel data, this study used fixed-effects regressions and first differences ordinary least squares (OLS)…

The factor structure of the CORE Phonics Survey was analyzed using a sample of 165 students in upper elementary school with specific learning disabilities. Confirmatory factor analysis was used to identify the hypothesized constructs of the CORE Phonics Survey and predictive validity of the CORE Phonics Survey to predict students' success in word…

Response to Intervention (RtI) promotes a well-integrated system connecting general, compensatory, gifted, and special education in providing high quality, standards-based instruction and intervention that are matched to students' academic, social-emotional, and behavioral needs. There are three levels to this framework. Tier 1 (or Universal) is…

Two professional development (PD) models for teachers were compared on teacher and student outcomes. Special education teachers participated in Literacy Learning Cohorts (LLC), a PD innovation designed to improve content and pedagogical knowledge for providing reading instruction to upper elementary students with learning disabilities. The LLC,…

Background: Reading disability (RD) and attention deficit/hyperactivity disorder (ADHD) are comorbid and genetically correlated, especially the inattentive dimension of ADHD (ADHD-I). However, previous research indicates that RD and ADHD enter into opposite gene by environment (G x E) interactions. Methods: This study used behavioral genetic…

In this study, we conducted 124 observations of 41 special education teachers teaching reading to their third- through fifth-grade students with learning disabilities to determine the extent to which and in what ways they promoted students' reading comprehension. In 42 lessons, we did not observe any comprehension instruction. In 30 lessons, the…

Response to Intervention (RtI) has promise for helping students, particularly ones with disabilities, achieve higher levels of academic and behavioral success in the general education classroom. What does it mean for gifted students or for those who are gifted and have a learning disability, such as twice-exceptional students? How might current…

As a practicing school psychologist and administrator at Brown International Academy, an inner city elementary school in Denver Public Schools, the author believes that if the RTI model is put into practice, it will greatly impact educational outcomes for all students. Putting RTI into practice is not easy. It requires individuals to think…

This case history of the Colorado Study of Learning Disabilities illustrates a variety of functions an evaluation study may serve for policy shapers at the state level. The impact of the initial evaluation is followed over two years, focusing on its use by influential participants in Colorado's special education policy-shaping community. (BW)

The characteristics of a sample of school-aged children identified as learning disabled (LD) are described. They were characterized by distributions of single variables (e.g., discrepancy between IQ and achievement) and hierarchical classification creating subgroups within the LD sample. Fewer than half the sample exhibited characteristics…
