ABSTRACT
The cognitive and behavioral deficits associated with air pollution exposure may have far-reaching negative effects on children's scholastic achievement. Moreover, air pollution may be conditioning the success of educational investments that support students who face greatest levels of societal adversity. This study examined the direct main effects of cumulative neurotoxicological exposure on annual reading improvement. We also tested the statistical interaction (i.e., moderation) of neurotoxicological exposure and academic intervention sessions on annual reading improvement for a large sample of ethnic minority (95%) elementary school children (n = 6080, k-6th grade) enrolled in a standard literacy enrichment program. These children were all behind grade level in reading and attended predominantly low-income schools (n = 85) in urban settings across the state of California. Multi-level modeling assessments accounted for random effects associated with school and neighborhood environments, and incorporated extensive individual, school, and community level covariates. Findings show individual elementary students of color to progress less in reading when exposed to greater accumulations of neurotoxin air pollution in their home and school environments, with the average deficit equivalent to 1.5 weeks of learning delay per year. Findings also show neurotoxicological exposure to diminish the efficacy of literacy intervention sessions received on reading improvement throughout the school year. Results suggest that pollution abatement can be a salient strategy to help bridge the child educational achievement gap. In addition to several methodological strengths, this study is one of the first to show that ambient pollution can undermine program efficacy of a literacy enrichment program.

ABSTRACT
A majority of reading-related intervention studies aiming to remediate struggling readers' reading outcomes assess student performance immediately following the conclusion of an intervention to determine intervention effects. Few studies collect follow-up data to measure the long-term sustainability of treatment effects. Hence, the aim of the current synthesis was to examine follow-up intervention effects of reading interventions involving adolescent struggling readers in Grades 6 to 12. Our literature search yielded only 10 studies that reported follow-up data for intervention participants, which highlights the dearth of intervention research that examines sustainability of intervention effects. Of the 10 included studies, the weighted mean effect size for all reading outcome measures was gw = 0.78 at immediate posttest and gw = 0.27 at follow-up, in favor of treatment group students. Although the magnitude of difference between treatment and control groups diminished at follow-up time, a comparison of treatment group students' immediate posttest and follow-up scores showed that students mostly maintained gains made during intervention at follow-up time points.

This editorial follows an influential review paper published in Brain Sciences in 2018 (What is Developmental Dyslexia? by John Stein). In this editorial, I present a critical look at the arguments in Stein's review, with a particular view towards "looking ahead". In looking ahead, I will focus on why dyslexia has been largely neglected by psycholinguistics and, in particular, shortfalls in knowledge about sentence processing. I will highlight some things that I think psycholinguistic methodologies can contribute to the understanding of developmental dyslexia. The editorial will then turn to address the larger research context of dyslexia. In short, investigations of dyslexia tend to be conducted across a wide range of disciplines, and by individuals with varied backgrounds, divergent views, and different goals. One argument I advance is that dyslexia has reached a point where "interdisciplinary" collaboration is essential, and in the event that that is not successful, the field would at least benefit from "adversarial collaborations". Finally, I briefly address the issue of interventions (raised by Stein) for older children and adolescents by returning to the contributions that psycholinguistics can provide to dyslexia. The crux of my argument here is that there exists a missing link in interventions, and that missing link is sentence-level language comprehension.
ABSTRACT
Reading achievement scores for adolescents with disabilities are markedly lower than the scores of adolescents without disabilities. For example, 62% of students with disabilities read below the basic level on the NAEP Reading assessment, compared to 19% of their nondisabled peers. This achievement gap has been a continuing challenge for more than 35 years. In this article, we report on the promise of a comprehensive 2-year reading program called Fusion Reading. Fusion Reading is designed to significantly narrow the reading achievement gap of middle school students with reading disabilities. Using a quasi-experimental design with matched groups of middle school students with reading disabilities, statistically significant differences were found between the experimental and comparison conditions on multiple measures of reading achievement with scores favoring the experimental condition. The effect size of the differences were Hedges's g = 1.66 to g = 1.04 on standardized measures of reading achievement.

Spelling is one of the most challenging areas for students with learning disabilities (LD), and improving spelling outcomes for these students is of high importance. In this synthesis, we examined the effects of spelling and reading interventions on spelling outcomes for students with LD in Grades K through 12. A systematic search of peer-reviewed literature published between 2004 and 2014 was conducted using electronic databases and hand searches of relevant journals. To be eligible for inclusion, studies had to meet the following criteria: (a) Participants were identified with LD and were in Grades K through 12, (b) designs were either treatment/comparison or single case, (c) a reading or spelling intervention was implemented, (d) at least one spelling outcome was measured, and (e) instruction was in English. Ten studies met criteria for inclusion in the synthesis, and effectiveness ranged from ineffective to highly effective. Findings demonstrated that spelling outcomes for taught words were improved for students with LD with the use of explicit instruction or self-correction strategies.

The history of research on interventions for struggling readers in Grades 4 through 12 dates back to 19th-century case studies of seemingly intelligent children who were unable to learn to read. Physicians, psychologists, educators, and others were determined to help them. In the process, they launched a century of research on a wide variety of approaches to reading intervention. As shown in this systematic narrative review, much has changed over time in the conceptualization of reading interventions and the methods used to determine their efficacy in improving outcomes for struggling readers. Building on the knowledge gathered over the past 100 years, researchers and practitioners are well-poised to continue to make progress in developing and testing reading interventions over the next 100 years.
ABSTRACT
This study examined the effects of an experimentally derived, peer-delivered reading intervention on the oral reading fluency of a first-grade student who had been referred for poor reading fluency. Same-grade peers were trained to lead the target student through a structured intervention protocol based on the results of a brief experimental analysis. Results indicated that reading improvements were obtained and are discussed in terms of selecting efficient interventions for use by peers.
