This study is an examination of the incremental validity of Cattell-Horn-Carroll (CHC) broad clusters from the Woodcock-Johnson III Tests of Cognitive Abilities (WJ III COG) for predicting scores on the Woodcock-Johnson III Tests of Achievement (WJ III ACH). The participants were children and adolescents, ages 6-18 (n = 4,722), drawn from the WJ…

Fluency is an essential part of skilled reading that has only recently begun to receive its deserved attention. However, programs that meaningfully engage adult learners in fluency training have not been widely explored in research. In this article, the authors describe an evidence-based adult Guided Repeated Reading program developed for…

This study investigates second language acquisition of learners enrolled in a dual language/two-way bilingual immersion program. Two groups of third-grade students participated in this study. The first group was composed of Spanish-dominant participants learning English, and the second group was composed of English-dominant students learning…

Research indicates the primary difference between strong and weak readers is their phonemic awareness skills. However, there is no consensus regarding which specific components of phonemic awareness contribute most robustly to reading comprehension. In this study, the relationship among sound blending, sound segmentation, and reading comprehension…

This experimental study examined the efficacy of a multicomponent reading intervention compared to a control condition on the reading comprehension of adolescent students with low reading comprehension (more than 1½ standard deviations below normative sample). Ninth-grade students were randomly assigned to treatment (n = 25) and comparison (n =…

In the context of a persistent achievement lag among low-income children despite substantial investments in early education, policymakers and practitioners continue to seek ways to improve the quality of children's preschool experiences. The Making Pre-K Count study addresses whether strengthening prekindergarten (pre-K) instruction in math,…

The Cross-Battery Assessment (XBA) approach to identifying a specific learning disorder (SLD) is based on the postulate that deficits in cognitive abilities in the presence of otherwise average general intelligence are causally related to academic achievement weaknesses. To examine this postulate, we conducted a classification agreement analysis…

Expressive writing is important for school and life success, but remains challenging for many students with emotional and behavioral disabilities. Emerging evidence reveals promise for teaching students with learning and behavioral issues to improve written expression with self-regulated strategy development instruction. In that research, students…

This randomized control study compares the efficacy of two response-to-intervention (RTI) models: (1) Dynamic RTI, which immediately refers grade 1 students with the weakest skills to the most intensive intervention supports (Tier 2 or Tier 3); and (2) Typical RTI, which starts all students in Tier 1 and after 8 weeks, decides whether students who…

Reading comprehension is an important skill for college academic success. Much of the research pertaining to reading in general, and reading comprehension specifically, focuses on the success of primary and secondary school-age students. The present study goes beyond previous research by extending such investigation to the reading comprehension of…

Despite data supporting the benefits of early reading interventions, there has been little evaluation of the long-term educational impact of these interventions, with most follow-up studies lasting less than 2 years (Suggate, 2010). This study evaluated reading outcomes more than a decade after the completion of an 8-month reading intervention…

This paper capitalizes on the addition of geocodes for Head Start centers in which children were randomly assigned to address questions about the role of neighborhood characteristics in moderating impacts of assignment to the Head Start program. Researchers explore the extent to which impacts of assignment to Head Start on outcomes for children…

This article examines the effect of improvements in timing/rhythmicity on mathematics achievement. A total of 86 participants attending 1st through 4th grades completed pre- and posttest measures of mathematics achievement from the Woodcock-Johnson III Tests of Achievement. Students in the experimental group participated in a 4-week intervention…

Students with mild intellectual disability generally garner less individual attention in research, as they are often aggregated with students with moderate and severe intellectual disability or students with other high incidence disabilities. This study used the National Longitudinal Transition Study-2 (NLTS2) to look at the personal…

This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that…
