The purpose of this study was to investigate whether preschool children with language impairments (LI), a group with documented reading difficulties, also experience writing difficulties. In addition, a purpose was to examine if the writing outcomes differed when children had concomitant cognitive deficits in addition to oral language problems. A…

In this longitudinal study, we investigated the role of word reading and mathematical difficulties measured in 9th grade as factors for receiving educational support for learning in upper secondary education in Grades 10 to 12 (from ages 16 to 19) and furthermore as predictors of dropout from upper secondary education within 5 years after…

Two reasons may be responsible for the poor grasp of the linguistic concepts related to literacy acquisition by preservice and in-service teachers: a lack of attention given to such concepts by teacher educators (college faculty members) and a lack of relevant information provided in the textbooks used in college courses. In an earlier study, the…

The purpose of this article is to describe the current research base and identify research needs related to response to intervention (RTI) frameworks in primary-grade reading. Research is reviewed on early reading instruction and intervention, the implementation of multitiered reading interventions, and the determination of intervention…

The Education for All Handicapped Children Act (EHCA) was legislated in 1975 in part to provide funding to states, parent centers, and research centers, for supporting access to public education for students with disabilities. In 1975, the intent of EHCA was to find children with disabilities and ensure that children were evaluated, identified,…

Despite the emerging evidence base on response to intervention, there is limited research regarding how to effectively use progress-monitoring data to adjust instruction for students in Tier 2 intervention. In this study, we analyzed extant data from a series of randomized experimental studies of a kindergarten supplemental reading intervention to…

Many college students receiving accommodations for specific learning disability (SLD) do not meet objective criteria for the disorder. Furthermore, whether students meet criteria depends on the diagnostic decision model used by their clinician. The authors examined whether the relationship between diagnostic model and likelihood of meeting…

The purpose of this study was to examine the construct and predictive validity of a dynamic assessment (DA) of decoding learning. Students (N = 318) were assessed in the fall of first grade on an array of instruments that were given in hopes of forecasting responsiveness to reading instruction. These instruments included DA as well as…

This study investigated the hypothesis that the contributions of oral language comprehension ("C") and word recognition ("D") to reading comprehension ("R") in the simple view of reading (SVR) are not independent because a component of "C" (vocabulary knowledge) directly contributes to the variance in…

To explore possible reasons for low self-identification rates among undergraduates with learning disabilities (LD), we asked students (38 with LD, 100 without LD) attending two large, public, research-intensive universities to respond to a questionnaire designed to assess stereotypes about individuals with LD and conceptions of ability. Responses…

Babbling between the ages of 8 and 19 months was examined in 19 children, 13 of whom were at high risk for reading disorder (RD) and 6 normally reading children at low familial risk for RD. Development of syllable complexity was examined at five periods across this 11-month window. Results indicated that children who later evidenced RD produced a…

This article compares and contrasts the main features of dynamic testing and assessment (DT/A) and response to intervention (RTI). The comparison is carried out along the following lines: (a) historical and empirical roots of both concepts, (b) premises underlying DT/A and RTI, (c) terms used in these concepts, (d) use of these concepts, (e)…

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…

In this article, the authors consider the power and limitations of responsiveness-to-intervention (RTI) for reducing the need for ongoing and intensive services for the segment of the school population traditionally identified as having a learning disability in mathematics. To assess the robustness of RTI, the authors describe four studies with…

This article focuses on some of the linguistic components that underlie letter-sound decoding skills and reading comprehension: specifically phonology, morphology, and syntax. Many children who have reading difficulties had language deficits that were detectable before they began reading. Early identification of language difficulties will…
