Students at all grade levels in the United States are experiencing significant difficulties in the area of written expression (Salahu-Din, Persky, & Miller, 2008; U.S. Department of Education, 2012). Although performance feedback is an effective evidence-based intervention for improving the writing fluency of elementary-aged students,…

Although research suggests that certain cognitive functions predict the likelihood of intervention response for students who receive Tier 2 instruction through a response to intervention framework, researchers know less about cognitive predictors of response to Tier 3 instruction. This study measured 2nd and 3rd graders' performance on 7 cognitive…

Most research on early identification of reading disabilities has focused on word reading problems and little attention has been given to reading comprehension difficulties. In this study, we investigated whether measures of language ability and/or response to language intervention in kindergarten uniquely predicted reading comprehension…

Current research suggests that certain cognitive functions predict the likelihood of intervention response for students who receive Tier 2 instruction through an RTI-framework. However, less is known about cognitive predictors of responder status at a theoretically more critical point of divergence within the RTI model: Tier 3. Moreover, no…

We explored the usefulness of first and second grade reading measures and responsiveness criteria collected within a response-to-intervention (RtI) framework for predicting reading disability (RD) in third grade. We used existing data from 387 linguistically diverse students who had participated in a longitudinal RtI study. Model-based predictors…

Despite flexibility waivers granted to states by the United States Department of Education from some provisions of the No Child Left Behind Act, our nation's public schools continue to struggle to improve reading proficiency as measured by high stakes assessments. To reach state targets for reading proficiency schools must use data at the earliest…

This study examined students' movement in and out of special education and predictors for later special education placement. The sample ( N = 556) came from a response to intervention (RTI) study, specifically, a cluster-randomized control field trial that undertook the development and study of a hybrid Tier 1 (classroom instruction) and Tier 2…

The purpose of this study was to explore the utility of a dynamic assessment (DA) of algebraic learning in predicting third graders' development of mathematics word-problem difficulty. In the fall, 122 third-grade students were assessed on a test of math word-problem skill and DA of algebraic learning. In the spring, they were assessed on…

Reading is the most valuable skill children must master early in schooling. Unfortunately, many students struggle to read and may be identified as having a Reading Disability (RD). In this dissertation, I explored the usefulness of the Response-to-Intervention (RtI) framework for identifying children with RD by examining the use of 1st and 2nd…

The purpose of this study was to document the relationship between two commonly-used indicators of reading proficiency (i.e., Oral Reading Fluency [ORF] and Retell Fluency [RTF]) and two reading outcome tests in the state of Montana. Third and fourth grade students were assessed over 1 school year (2005-2006). Each student was assessed at three…

A fundamental assumption in the identification of specific learning disabilities (SLD) has been that the presence of a severe discrepancy between ability and academic achievement is a valid marker for the presence of a SLD. This assumption is based on the notion that discrepant low achievers constitute a unique group of children who are different…
