The main goal of this study was to enhance the field's understanding of early reading comprehension development and its underlying subcomponent skills, with the intent of better understanding the development of comprehension in students who display risk for reading difficulties and disabilities. A sample of first-grade readers ( = 314) were assessed at three timepoints across the first-grade year. These data were utilized to derive empirical latent classes based on reading comprehension performance across the first-grade year. Reading subcomponent skill assessments (phonological awareness, word reading, decoding, linguistic comprehension, and reading fluency), measured in the fall of first grade, were compared across latent classes to examine how they related to growth across the first-grade year. Results suggest that there were four distinct latent classes with differential reading comprehension development, each of which could also be distinguished by the subskill assessments. These findings are presented within the context of the broader reading research base, and implications for practice are discussed.

The articles address multiple aspects of a model of DBDM that includes the role of teacher knowledge, skills, beliefs, and sources of professional learning and the role of systems-level factors in improving student achievement. In this article, the conclusions of each paper are described in terms of that model. The papers illustrate that DBDM can improve achievement for students with learning disabilities through a DBDM process called data-based individualization (DBI)-especially if teachers have innovative supports (e.g., new technologies). For teachers, DBDM professional development (PD) can improve DBDM knowledge and implementation, but PD may not be adequate in all cases, with practical experience playing a central role. In addition, classroom-level DBDM may not translate to success for students with learning disabilities. Finally, the articles reveal a need to focus more on systems-level factors in successful DBDM systems like DBI-especially when implemented outside the experimental context. These findings provide a contemporary lens on DBDM as it related to students with learning disabilities and establish foci for future research.

A major challenge to these efforts is how to define and operationalize dyslexia. In this article, we argue that rather than defining dyslexia on the basis of an underlying condition, dyslexia is best viewed as a label for an unexpected reading disability. This view fits well with a preventive approach in which risk for reading disability is identified and addressed prior to children experiencing reading failure. A risk-resilience model is introduced that proposes that dyslexia is due to the cumulative effects of risk and resilience factors. Evidence for the multifactorial causal basis of dyslexia is reviewed and potential factors that may offset this risk are considered. The implications of a cumulative risk and resilience model for early identification and intervention is discussed.

The participants were 246 eighth-grade students from an English-immersion program in a middle school in China. Latent profile analysis identified three reading groups in each language: (a) a typically developing reader group with average or above-average word-reading and reading comprehension, (b) a group with poor decoding/word-reading skills and weak reading comprehension, and (c) a group with poor reading comprehension in the absence of poor decoding/word reading. The overlap in profile characteristics across languages for typically developing readers and poor decoders was high (about 68% for typically developing readers and 54% for poor decoders), whereas the overlap for being poor comprehenders in each language was moderate (about 37%). Furthermore, poor decoders in either language performed more poorly than the typically developing and poor comprehender groups on word reading in the other language, while poor comprehenders in either language performed more poorly than the typically developing and poor decoder groups on reading comprehension in the other language. The comparison of the reading groups' performance on English reading-related language comprehension measures showed that poor comprehenders and poor decoders performed worse than typically developing readers. Implications for identification and instruction of ESL children with reading difficulties are discussed.

One byproduct of this most challenging situation has been the interruption of scientific inquiry in many fields, including educational research. Using a framework of self-leadership, in this feature article, we provide reflections to guide discussion among scholars involved in school-based research during and after the COVID-19 pandemic. Based on lessons learned in our own mentee-mentor relationships and from our collective experiences, the purpose of this article is to offer considerations primarily for early-career scholars, but also to engage dialogue among mid- and late-career scholars to promote school-based inquiry in this defining moment in history, at a time when educators are concerned with mitigating learning loss. We focus on (a) revisiting and refining programmatic lines of inquiry, (b) crafting articles to disseminate lessons learned from research conducted to date-including those with lost time points, (c) retooling in a focused area of inquiry (e.g., methodology), (d) conceptualizing future studies featuring procedures that do-and do not-allow for interpersonal contact, and (e) appreciating and acknowledging individuals who have facilitated inquiry. We conclude with a note of encouragement and call to action for future educational research.

In this series, we bring together international researchers from both special and general education to address teachers' use (or non-use) of data for instructional decision making. Via this special series, we aim to increase understanding of the challenges involved in teachers' data-based instructional decision making for students with or at-risk for learning disabilities, and to further the development of approaches for improving teachers' ability to plan, adjust, and adapt instruction in response to data.

What drives these individual differences remains unclear. In the current article, data from the Twin Early Development Study were used to investigate the genetic and environmental influences on psychopathology in children and adolescents with DLD ( = 325) and those without DLD ( = 865). Trivariate models were fitted to investigate etiological influences on DLD and psychopathology, and bivariate heterogeneity and homogeneity models were fitted and compared to investigate quantitative differences in etiological influences on psychopathology between those with and without DLD. The genetic correlation between DLD and internalizing problems in childhood was significant, suggesting that their co-occurrence is due to common genetic influences. Similar, but nonsignificant effects were observed for externalizing problems. In addition, genetic influences on internalizing problems, but not externalizing problems, appeared to be higher in young people with DLD than those without DLD, suggesting that the presence of DLD may exacerbate genetic risk for internalizing problems. These findings indicate that genetic influences on internalizing problems may also confer susceptibility to DLD (or vice versa) and that DLD serves as an additional risk factor for those with a genetic predisposition for internalizing problems.

Eighty-four Cantonese-speaking children officially diagnosed with dyslexia ( = 103 months) and 48 age-matched typically developing (TD) children were tested. Cluster analysis with performances on Chinese syllable awareness (CSA), Chinese phonemic awareness (CPA), Chinese phonological memory (CPM), Chinese orthographic awareness (COA), and matrix reasoning (MR) yielded three cognitive subtypes: the phonological deficit (PD) subtype, the orthographic deficit (OD) subtype, and the global deficit (GD) subtype. After controlling for English language experience, age, and gender, all three dyslexia subtype groups performed significantly worse in English word reading fluency and dictation than the TD children. In addition, the PD group performed worse in English PA; the OD group performed worse in English OA; and the GD group performed worse in all English skills except English PM. We compared the level of impairment in literacy between languages and dyslexia subtypes. In word reading fluency, all subtype groups experienced less impairment in English than Chinese, while the OD group showed the largest English advantage. In dictation, only the OD group showed a significant language effect favoring English. The findings suggest that different subtypes of Chinese dyslexia bear different risks for difficulties in English literacy.

The current study evaluates whether students' baseline word reading skills predict their response to a MCRI. Data from a randomized controlled trial for third- and fourth-grade students with reading difficulties ( = 128) were analyzed. Results demonstrate that baseline word reading was a significant predictor of students' end-of-year reading comprehension performance. Treatment group students who had lower baseline word reading compared with those students with comparatively higher word reading scores performed significantly lower on posttest reading comprehension. Findings denote the importance of word reading instruction for upper elementary students who are below-average word readers and also indicate the need for tailoring reading intervention to align with individual reader needs.

To support teachers in adapting instruction to these heterogeneous classrooms, we have developed learning progress assessment (LPA) and reading instructional materials, the (RS), in line with the theoretical framework of data-based decision-making, which has led to beneficial effects in several studies. However, data from these studies have not been analyzed to examine effects for low-performing readers. Data within and across six quasi-experimental studies conducted by our team in Grades 2 to 4 were reanalyzed to examine the effects of LPA on students whose reading fluency scores were at or below the 25th percentile ( = 1,346 students from 264 classes). In each study, students had been assigned to a control group (with business-as-usual instruction), an LPA group only, or an LPA-RS group (i.e., with teachers provided with LPA and the RS). Separate multilevel regression results were integrated by means of meta-analytical methods to investigate the consistency of results. Overall, findings from the single studies indicated no positive effects of LPA with or without the RS compared with the control group. The integrated analyses showed small positive effect trends on reading fluency and intrinsic reading motivation.

In this meta-analysis, we determined summary effects of mean and variance differences in creativity between groups with and without dyslexia. Twenty studies were included ( = 770 individuals with dyslexia, = 1,671 controls). A random-effects robust variance estimation (RVE) analysis indicated no mean ( = -0.02, = .84) or variance ( = -0.0004, = .99) differences in creativity between groups. The mean summary effect was moderated by age, gender, and creativity domain. Compared with adolescents, adults with dyslexia showed an advantage over nondyslexic adults in creativity. In addition, a higher proportion of males in the dyslexia group was associated with poorer performance compared with the controls. Finally, the dyslexia group showed a significant performance disadvantage in verbal versus figural creativity. Regarding variance differences, they varied across age and creativity domains. Compared with adults, adolescents showed smaller variability in the dyslexia group. If the creativity task measured verbal versus figural or combined creativity, the dyslexia group exhibited smaller variability. Altogether, our results suggest that individuals with dyslexia as a group are no more creative or show greater variability in creativity than peers without dyslexia.

Children classified as having DD often have a history of early language delay (ELD) or language impairments. Nevertheless, studies have reported conflicting results as to the association between DD-ELD and the extent of current language difficulties in children with DD. To examine these relationships, we queried the parents of school-age children with reading difficulties on their child's early and current language ability. Siblings were also examined. Children were directly assessed using quantitative tests of language and reading skills. To compare this study with the literature, we divided the sample ( = 674) into three groups: DD, intermediate readers (IR), and skilled readers (SR). We found a significant association between DD and ELD, with parents of children in the DD/IR groups reporting their children put words together later than the SR group. We also found a significant association between DD and language difficulties, with children with low reading skills having low expressive/receptive language abilities. Finally, we identified early language predicted current language, which predicted reading skills. These data contribute to research indicating that children with DD experience language difficulties, suggesting early recognition may help identify reading problems.

The participants consisted of 124 students in Grade 6 who were randomly assigned to an experimental group or a control group. Each group was further divided into readers with dyslexia, poor readers, and typical readers groups. The experimental group participated in an English intervention program designed for this study. All participants were administered a battery of pre- and post-treatment tests in linguistic and meta-linguistic skills in Hebrew and in English. The findings supported the existence of CRT from skills in English to skills in Hebrew with reference to most of the variables in the domains of reading, writing, and language skills. The improvement in most of the linguistic and meta-linguistic tasks in both English and Hebrew was significantly higher in the experimental group compared with the control group. The innovation of this study was in testing CRT of linguistic and meta-linguistic skills from English to Hebrew. Limitations and direction for future research are discussed.

The purpose of this study was to synthesize the literature on interventions that used virtual manipulatives to improve the mathematics performance of K-12 students with learning disabilities. A total of 19 single-case design studies (16 peer-reviewed articles and three dissertations) were selected using specific selection criteria. Overall, students with learning disabilities demonstrated mathematical improvement after receiving interventions involving virtual manipulatives. Although many students with learning disabilities maintained and generalized the intervention effects, further research is required to verify the current findings.

A prediction based on this view is that the same spelling training should be equally effective for learning to spell in a shallow (Italian, native language) or an opaque (English, additional language) orthography. We tested this prediction by teaching 6- to 9-year-old Italian children to use multiletter spelling units to spell words in Italian and English. The children were trained on the spelling of Italian words containing orthographic difficulties that required switching from phoneme-grapheme spelling correspondences to larger grain size (multiletter) spelling units. In a stepped-wedge cluster randomized trial, 108 Italian children (ages 6-9 years) were assigned to the experimental spelling training or a waiting list condition. Their ability to spell the trained (Italian and English) word lists and to generalize the acquired knowledge to new (untrained) words was assessed. Similar learning effects were found in the two languages for the trained word lists. However, generalization of the acquired spelling knowledge to new words occurred only in English. The influence of language-specific factors on learning to spell could account for these findings.

We begin by summarizing a recent meta-analysis of CBM-DBI studies focused on academic outcomes. We then reconsider studies from that meta-analysis to further explore the supports required to enrich teachers' instructional decision-making within CBM-DBI and improve student learning. We next draw conclusions and propose a renewed program of instructional utility CBM-DBI research for capitalizing on technology's potential to enhance productive instructional decision-making for students who require intensive intervention, fulfill DBI's potential, and bring CBM-DBI to scale.

This study represents an initial investigation of whether classroom teachers' intervention fidelity (exposure, adherence, and quality) of targeted reading instruction (TRI, formerly called targeted reading intervention), a professional development program with embedded student intervention and weekly webcam literacy coaching support, was related to spring reading and oral vocabulary gains for students at risk for reading-related disabilities. The study also examined whether teachers' years of participation in TRI (1 year vs. 2 years) moderated associations between intervention fidelity and students' reading and oral vocabulary outcomes. Findings suggested that teachers' adherence to TRI strategies was directly associated with students' vocabulary gains as well as word reading skills for teachers in their second year of participation. Furthermore, when teachers provided students with more TRI exposure during their second year of participation, students made greater gains in word reading and reading comprehension.

Sixty-nine CBM instructional sources were reviewed, including 45 presentations, 22 manuals, and two books. The content of the presentations and manuals/books was coded into one of four categories: (a) general CBM information, (b) conducting CBM, (c) data-based decision-making, and (d) other. Results revealed that only a small proportion of information in the CBM instructional materials was devoted to data-based decision-making (12% for presentations and 14% for manuals/books), and that this proportion was significantly smaller than (a) that devoted to other instructional topics, (b) that expected were information to be equally distributed across major instructional topics, and (c) that recommended by experienced CBM trainers. Results suggest a need for increased attention to data-based decision-making in CBM professional development.

We investigate whether the intervention affects not just reading comprehension levels, but also how variables within the reading system interrelate. This approach allows the focus to shift from intervention as influencing a change in reading comprehension status to a complex set of processes. We fit structural equation models (SEMs) to evaluate the DIME model at baseline and a change model that included reading comprehension and word reading at posttest. There were no significant mean differences between groups in reading comprehension. However, significant differences emerged on the direct and indirect effects of background knowledge, vocabulary, word reading, strategies, and inferencing on comprehension across grade levels and treatment conditions. Related to treatment groups, background knowledge, vocabulary, and inferencing were significantly related to comprehension at posttest for students who received text processing and/or foundational skills interventions. The results have implications for the direct instruction of higher-order reading skills in the context of multicomponent interventions.

The search yielded 17 studies examining reading fluency and comprehension outcomes. Most studies examined repeated reading (RR) interventions to improve reading fluency for struggling readers at these grade levels, resulting in improved fluency but few positive effects on reading comprehension outcomes, similar to trends observed in prior systematic reviews. Reading connected text with an equivalent word count to word counts of RR sessions did not result in increased reading fluency, a finding aligned with a prior synthesis. Few studies used a fluent reader as a model prior to RRs, despite previous support for modeling within fluency interventions.
