Evaluating the Efficacy of a Narrative Language Intervention for Bilingual Students.

PURPOSE: This study examines the narrative language and reading outcomes of monolingual and bilingual students who received instruction with the Supporting Knowledge in Language and Literacy (SKILL) program, a narrative language intervention. METHOD: The main effects of the SKILL program were evaluated in a randomized controlled trial in which students (N = 355) who were at risk for English language and literacy difficulties were randomized to the SKILL intervention or a business-as-usual instruction. This article reports secondary analyses examining the efficacy of SKILL for bilingual (n = 148) and monolingual (n = 207) students who completed measures of oral and written narrative language and reading comprehension in English. RESULTS: Moderation results showed that the effects of SKILL did not differ for monolinguals and bilinguals across most narrative language measures and did not vary for monolinguals or bilinguals based on their pre-intervention language performance. CONCLUSION: These findings that suggest a language-based approach to improving narrative production and comprehension yielded similar results for monolinguals and bilinguals and that neither monolinguals nor bilinguals in this study needed to meet a certain threshold of English language proficiency to benefit from the intervention.

Examining fidelity reporting within studies of foundational reading interventions for elementary students with or at risk for dyslexia.

Early access to evidence-based reading intervention improves outcomes for students with or at risk for reading difficulties. Additionally, teacher implementation of reading interventions plays a key role in the efficacy of reading interventions. Previous research suggests the influence of intervention implementation fidelity on student language and literacy outcomes is more significant for lower-performing students and students with disabilities, such as dyslexia. However, recent syntheses have suggested that less than half of reading intervention studies report treatment fidelity data. This meta-analysis examined fidelity reporting within reading intervention studies for students with or at risk for dyslexia in Grades K-5. We aimed to record the frequency and extent of fidelity reporting, explore associations between study or intervention features and fidelity reporting, and compare mean intervention effect sizes for studies reporting fidelity and those that did not. A total of 51 studies were included. Results indicated that 75% of studies reported fidelity data. Studies reporting fidelity primarily focused on adherence and dosage data with little to no information reported for other dimensions of fidelity (i.e., quality, responsiveness, differentiation). Suggestions for improving reporting of treatment fidelity data are discussed.

A meta-analysis of the effects of foundational skills and multicomponent reading interventions on reading comprehension for primary-grade students.

This meta-analysis examined the effects on reading comprehension of foundational reading skills and multicomponent reading interventions provided to students with or at risk for reading difficulties or disabilities (students with RDs) in kindergarten through Grade 3. The meta-analysis included studies identified by Wanzek et al. (2016) and Wanzek et al. (2018), with an updated search through August of 2019, for a total of 47 included studies (m = 112; total student N = 7446). The weighted average effect on norm-referenced reading comprehension outcomes was estimated as g = 0.37, indicating that primary-grade interventions have an educationally meaningful effect on reading comprehension for students with RDs. Effects did not differ for interventions focused only on foundational reading skills and those that provided both foundational skills and comprehension instruction. Effects were significantly moderated by the measurement timepoint, with follow-up effect sizes being, on average, 0.16 smaller than immediate posttest effect sizes.

Current Research Informing the Conceptualization, Identification, and Treatment of Dyslexia Across Orthographies: An Introduction to the Special Series.

This introduction to the special series summarizes evidence for the genetic and brain bases for dyslexia and cognitive-behavioral indicators (including ones that can be measured even before the onset of reading instruction) that attest to meaningful differences between children with dyslexia and their non-dyslexic peers. Authors review controversies that have surrounded approaches to dyslexia identification and treatment during the last few decades. Finally, they introduce the findings of the articles in the special series and discuss potential implications for dyslexia identification and treatment.

Reading Instruction for English Learners With Learning Disabilities: What Do We Already Know, and What Do We Still Need to Learn?

This paper reviews findings from four research syntheses that report the effects of academic language and/or reading interventions on language and reading outcomes for English learners who have or are at risk for learning difficulties. Studies included in the syntheses varied in research design and addressed multiple areas of reading and language. There was disagreement between syntheses as to the extent of research evidence in favor of particular instructional practices. For ELs with learning difficulties in kindergarten and first grade, however, there was strong consensus that multiple-component reading instruction that includes phonological awareness and phonics instruction is associated with improved word reading outcomes. It may also be beneficial to provide oral language, vocabulary, and reading comprehension instruction; nevertheless, there is a need for future research on instructional interventions that aim to improve reading comprehension outcomes for this population.
