A cluster randomized controlled trial of brief follow-up practice sessions on intervention maintenance. J Sch Psychol 2021; 88:31-46.

Abstract
Despite considerable knowledge of the factors that influence initial intervention response, little is known about how to sustain successful intervention response over time. The current study examined spring literacy outcomes for kindergarten (n = 177), second (n = 149), and third grade students (n = 204) who successfully exited an evidence-based tutoring program during the fall semester. Successful responders in kindergarten, second, and third grade were randomly assigned by school to receive either no follow-up support or access to a once-weekly oral practice session. Results were mixed across grades and outcomes, but in kindergarten and third grade, treatment corresponded to an approximately 15% increased likelihood of meeting year-end benchmarks on targeted literacy skills. Findings are discussed in the context of suggestions for higher-quality longitudinal research designs of educational interventions.

Abstract
In this study, we conducted a review of reading intervention research (1988-2019) for upper elementary struggling readers and examined intervention area (e.g., foundational, comprehension, or multicomponent) and intensity (e.g., hours of intervention, group size, and individualization) as possible moderators of effects. We located 33 studies containing 49 treatment-comparison contrasts, found small effects for foundational reading skills (g = 0.22) and comprehension (g = 0.21), and decreased effects when considering standardized measures only. For intervention area, only multicomponent interventions predicted significant effects for both comprehension and foundational outcomes. For intensity, we did not find systematic evidence that longer or individualized interventions were associated with larger effects. However, interventions implemented in very small groups predicted larger comprehension outcomes. Overall, more research examining the quality of school provided reading instruction and how the severity of reading difficulties may impact effects of more intensive interventions is needed.

Abstract
The visual word form area (VWFA) plays a significant role in the development of reading skills. However, the developmental course and anatomical properties of the VWFA have only limitedly been investigated. The aim of the current longitudinal MRI study was to investigate dynamic, bidirectional relations between reading, and the structure of the left fusiform gyrus at the early-to-advanced reading stage. More specifically, by means of bivariate correlations and a cross-lagged panel model (CLPM), the interrelations between the size of the left fusiform gyrus and reading skills (an average score of a word and pseudo-word reading task) were studied in a longitudinal cohort of 43 Flemish children (29M, 14F) with variable reading skills in grade 2 (the early stage of reading) and grade 5 (the advanced stage of reading) of primary school. Results revealed that better reading skills at grade 2 lead to a larger size of the left fusiform gyrus at grade 5, whereas there are no directional effects between the size of the left fusiform gyrus at grade 2 and reading skills at grade 5. Hence, according to our results, there is behavior-driven brain plasticity and no brain-driven reading change between the early and advanced stage of reading. Together with pre-reading brain studies showing predictive relations to later reading scores, our results suggest that the direction of brain-behavioral influences changes throughout the course of reading development.

Abstract
LAY ABSTRACT Many children and young students with autism have difficulties learning how to read. This study investigated early literacy development in children with autism spectrum disorder during their first year of formal schooling. The study found that children with autism spectrum disorder differ greatly on their early literacy skills, with some showing strengths in their understanding of the alphabet, spelling, and reading words. Other students in the sample had difficulties with these early reading skills. The findings of this study are important to better understand the most effective way to teach early literacy skills to children with autism spectrum disorder.

Abstract
Background Low levels of numeracy and literacy skills are associated with a range of negative outcomes later in life, such as reduced earnings and health. Obtaining information about effective interventions for children with or at risk of academic difficulties is therefore important. Objectives The main objective was to assess the effectiveness of interventions targeting students with or at risk of academic difficulties in kindergarten to Grade 6. Search Methods We searched electronic databases from 1980 to July 2018. We searched multiple international electronic databases (in total 15), seven national repositories, and performed a search of the grey literature using governmental sites, academic clearinghouses and repositories for reports and working papers, and trial registries (10 sources). We hand searched recent volumes of six journals and contacted international experts. Lastly, we used included studies and 23 previously published reviews for citation tracking. Selection Criteria Studies had to meet the following criteria to be included: Population: The population eligible for the review included students attending regular schools in kindergarten to Grade 6, who were having academic difficulties, or were at risk of such difficulties. Intervention: We included interventions that sought to improve academic skills, were conducted in schools during the regular school year, and were targeted (selected or indicated). Comparison: Included studies used an intervention-control group design or a comparison group design. We included randomised controlled trials (RCT); quasi-randomised controlled trials (QRCT); and quasi-experimental studies (QES). Outcomes: Included studies used standardised tests in reading or mathematics. Setting: Studies carried out in regular schools in an OECD country were included. Data Collection and Analysis Descriptive and numerical characteristics of included studies were coded by members of the review team. A review author independently checked coding. We used an extended version of the Cochrane Risk of Bias tool to assess risk of bias. We used random-effects meta-analysis and robust-variance estimation procedures to synthesise effect sizes. We conducted separate meta-analyses for tests performed within three months of the end of interventions (short-term effects) and longer follow-up periods. For short-term effects, we performed subgroup and moderator analyses focused on instructional methods and content domains. We assessed sensitivity of the results to effect size measurement, outliers, clustered assignment of treatment, risk of bias, missing moderator information, control group progression, and publication bias. Results We found in total 24,414 potentially relevant records, screened 4247 of them in full text, and included 607 studies that met the inclusion criteria. We included 205 studies of a wide range of intervention types in at least one meta-analysis (202 intervention-control studies and 3 comparison designs). The reasons for excluding studies from the analysis were that they had too high risk of bias (257), compared two alternative interventions (104 studies), lacked necessary information (24 studies), or used overlapping samples (17 studies). The total number of student observations in the analysed studies was 226,745. There were 93% RCTs among the 327 interventions we included in the meta-analysis of intervention-control contrasts and 86% were from the United States. The target group consisted of, on average, 45% girls, 65% minority students, and 69% low-income students. The mean Grade was 2.4. Most studies included in the meta-analysis had a moderate to high risk of bias.The overall average effect sizes (ES) for short-term and follow-up outcomes were positive and statistically significant (ES = 0.30, 95% confidence interval [CI] = [0.25, 0.34] and ES = 0.27, 95% CI = [0.17, 0.36]), respectively). The effect sizes correspond to around one third to one half of the achievement gap between fourth Grade students with high and low socioeconomic status in the United States and to a 58% chance that a randomly selected score of an intervention group student is greater than the score of a randomly selected control group student.All measures indicated substantial heterogeneity across short-term effect sizes. Follow-up outcomes pertain almost exclusively to studies examining small-group instruction by adults and effects on reading measures. The follow-up effect sizes were considerably less heterogeneous than the short-term effect sizes, although there was still statistically significant heterogeneity.Two instructional methods, peer-assisted instruction and small-group instruction by adults, had large and statistically significant average effect sizes that were robust across specifications in the subgroup analysis of short-term effects (ES around 0.35-0.45). In meta-regressions that adjusted for methods, content domains, and other study characteristics, they had significantly larger effect sizes than computer-assisted instruction, coaching of personnel, incentives, and progress monitoring. Peer-assisted instruction also had significantly larger effect sizes than medium-group instruction. Besides peer-assisted instruction and small-group instruction, no other methods were consistently significant across the analyses that tried to isolate the association between a specific method and effect sizes. However, most analyses showed statistically significant heterogeneity also within categories of instructional methods.We found little evidence that effect sizes were larger in some content domains than others. Fractions had significantly higher associations with effect sizes than all other math domains, but there were only six studies of interventions targeting fractions. We found no evidence of adverse effects in the sense that no method or domain had robustly negative associations with effect sizes.The meta-regressions revealed few other significant moderators. Interventions in higher Grades tend to have somewhat lower effect sizes, whereas there were no significant differences between QES and RCTs, general tests and tests of subdomains, and math tests and reading tests. Authors’ Conclusions Our results indicate that interventions targeting students with or at risk of academic difficulties from kindergarten to Grade 6 have on average positive and statistically significant short-term and follow-up effects on standardised tests in reading and mathematics. Peer-assisted instruction and small-group instruction are likely to be effective components of such interventions.We believe the relatively large effect sizes together with the substantial unexplained heterogeneity imply that schools can reduce the achievement gap between students with or at risk of academic difficulties and not-at-risk students by implementing targeted interventions, and that more research into the design of effective interventions is needed.

Abstract
Purpose This research note presents a secondary data analysis of language impairment (LI) prevalence rates of children in public schools before and after a statewide mandate for response-to-intervention (RTI) implementation. Method Statewide and district-level LI prevalence rates were compared across 10 school years. Prevalence data from 67 school districts located in 1 state in the United States are reported as the proportion of the general student population (students ages 3-21 years) who were identified with a primary disability of LI. Results The mandated implementation of RTI within special education prereferral, evaluation, and eligibility processes coincided with significant changes in LI prevalence as a primary disability for most of the school districts. The majority of school districts experienced an increase in LI prevalence within 1 school year following RTI implementation. However, the degree and direction of change in prevalence rates varied across some of the school districts. Similar degrees of change were not evident across the other years of prevalence data review, suggesting the systemic change that occurred via RTI requirements coincided with fluctuations in the LI prevalence rates for the majority of school districts in the state. Conclusion A causal relation between RTI and LI prevalence cannot be established with the current data; however, this study establishes a temporal connection between the timing of RTI implementation and changes in LI prevalence in public schools of 1 very large state. Implications are presented for further research investigating the potential impact of systemic mandates on the identification of school-age children with LI.

Microstructural properties of white matter pathways in relation to subsequent reading abilities in children: a longitudinal analysis. Brain Struct Funct 2019; 224:891-905.

Abstract
Microstructural properties of white matter pathways are associated with concurrent reading abilities in children. In this longitudinal study, we asked whether properties of white matter pathways at the onset of learning to read would be associated with reading abilities at older ages. Children (N = 37) with a wide range of reading abilities completed standardized measures of language and phonological awareness and diffusion MRI at age 6 years. Mean tract-fractional anisotropy (FA) was extracted from reading-related pathways. At age 8, the same children were re-assessed using a standardized reading measure. Using linear regressions, we examined the contribution of tract-FA at age 6 to reading outcome at age 8, beyond known demographic and pre-literacy predictors of reading. Tract-FA of the left arcuate, left and right superior longitudinal fasciculus (SLF), and left inferior cerebellar peduncle (ICP) made unique contributions to reading outcome after consideration of sex and family history of reading delays. Tract-FA of the left and right SLF and left ICP made unique contributions to reading outcome after the addition of pre-literacy skills. Thus, cerebellar and bilateral cortical pathways represented a network associated with subsequent reading abilities. Early white matter properties may be associated with other neuropsychological functions that predict reading or may influence reading development, independent of reading-related abilities. Tract FA at early stages of learning to read may serve as a biomarker of later reading abilities.

Abstract
Empirical studies investigating supplemental reading interventions for students with or at-risk for reading disabilities in the early elementary grades have demonstrated a range of effect sizes. Identifying the findings from high quality research can provide greater certainty of findings related to the effectiveness of supplemental reading interventions. This meta-analysis investigated how four variables of study quality (study design, statistical treatment, Type I error, and fidelity of implementation) were related to effect sizes from standardized measures of foundational reading skills and language/comprehension. The results from 88 studies indicated that year of publication was a significant predictor of effect sizes for both standardized measures of foundational reading skills and language/comprehension, with more recent studies demonstrating smaller effect sizes. Results also demonstrated that with the exception of research design predicting effect sizes on foundational reading skills measures, study quality was not related to the effects of supplemental reading interventions. Implications for research and practice are discussed.

Abstract
Although several measures exist for frequently monitoring early reading progress, little research has specifically investigated their technical properties when administered on a frequent basis with kindergarten students. In this study, kindergarten students ( N = 137) of whom the majority was receiving supplemental intervention for reading skills were monitored using Letter Sound Fluency, Phoneme Segmentation Fluency, Word Reading Fluency, Nonsense Word Fluency, Highly Decodable Passages, and Spelling on a biweekly basis between February and May. Acceptable reliability was observed for all measures. Analyses of slope validity using latent growth models, latent change score models, and slope differences according to level of year-end achievement indicated that the relation of slope to overall reading skills varied across the measures. A suggested approach to kindergarten students' reading progress is offered that includes Letter Sound Fluency and a measure of word-reading skills to provide a comprehensive picture of student growth toward important year-end reading outcomes.

Abstract
This meta-analysis extends previous work on extensive Tier 3 type reading interventions (Wanzek & Vaughn, 2007; Wanzek et al., 2013) to Tier 2 type interventions by examining a non-overlapping set of studies addressing the effects of less extensive reading interventions for students with or at risk for reading difficulties in Grades K-3. We examined the overall effects of these interventions on students' foundational skills, language, and comprehension as well as the intervention features that may be associated with improved outcomes. We conducted four meta-analyses on 72 studies to examine effects on (1) standardized foundational skill measures (mean ES = 0.54), (2) not-standardized foundational skill measures (mean ES = 0.62), (3) standardized language/comprehension measures (mean ES = 0.36), and (4) not-standardized language/comprehension measures (mean ES = 1.02). There were no differences in effects related to intervention type, instructional group size, grade level, intervention implementer, or the number of intervention hours.

Abstract
Two primary purposes guided this quasi-experimental within-teacher study: (1) to examine changes from baseline through two years of professional development (Individualizing Student Instruction) in kindergarten teachers' differentiation of Tier 1 literacy instruction; (2) to examine changes in reading and vocabulary of three cohorts of the teachers' students (n = 416). Teachers' instruction was observed and students were assessed on standardized measures of vocabulary and word reading. Results suggested that teachers significantly increased their differentiation and students showed significantly greater word reading outcomes relative to baseline. No change was observed for vocabulary. Results have implications for supporting teacher effectiveness through technology-supported professional development.

Abstract
We explored the usefulness of first and second grade reading measures and responsiveness criteria collected within a response-to-intervention (RtI) framework for predicting reading disability (RD) in third grade. We used existing data from 387 linguistically diverse students who had participated in a longitudinal RtI study. Model-based predictors of RD were analyzed using logistic regression; isolated measure/criteria combinations for predicting RD were analyzed using classification analysis. Models yielded superior classification rates compared to single measure approaches and did not systematically misclassify English learners. However, particular first and second grade measure/criteria combinations also showed promise as isolated predictors of RD in word reading/text fluency. Model-based approaches were required for acceptable classification of students with RD in comprehension. Although the former finding is promising for early identification of students in need of more intensive instruction in lexical or fluency-based skills, the latter finding reaffirms literature attesting to the complexity of RD in comprehension and difficulty of predicting deficits using early measures of reading, which primarily assess word reading skill. Results replicated well with an independent sample, thus enhancing confidence in study conclusions. Implications regarding the use of RtI for predicting RD are discussed.

Abstract
The cognitive model of reading comprehension (RC) posits that RC is a result of the interaction between decoding and linguistic comprehension. Recently, the notion of decoding skill was expanded to include word recognition. In addition, some studies suggest that other skills could be integrated into this model, like processing speed, and have consistently indicated that this skill influences and is an important predictor of the main components of the model, such as vocabulary for comprehension and phonological awareness of word recognition. The following study evaluated the components of the RC model and predictive skills in children and adolescents with dyslexia. 40 children and adolescents (8-13 years) were divided in a Dyslexic Group (DG; 18 children, MA = 10.78, SD = 1.66) and control group (CG 22 children, MA = 10.59, SD = 1.86). All were students from the 2nd to 8th grade of elementary school and groups were equivalent in school grade, age, gender, and IQ. Oral and RC, word recognition, processing speed, picture naming, receptive vocabulary, and phonological awareness were assessed. There were no group differences regarding the accuracy in oral and RC, phonological awareness, naming, and vocabulary scores. DG performed worse than the CG in word recognition (general score and orthographic confusion items) and were slower in naming. Results corroborated the literature regarding word recognition and processing speed deficits in dyslexia. However, dyslexics can achieve normal scores on RC test. Data supports the importance of delimitation of different reading strategies embedded in the word recognition component. The role of processing speed in reading problems remain unclear.

Abstract
This article synthesizes reading intervention research studies intended for use with struggling or at-risk students to determine which studies adequately address population validity, particularly in regard to the diverse reading needs of English language learners. An extensive search of the professional literature between 2001 and 2010 yielded a total of 67 reading intervention studies targeting at-risk elementary students. Findings revealed that many current research studies fail to adequately describe the sample, including the accessible and target populations, and to disaggregate their findings based on demographic characteristics. When population validity issues are not addressed, researchers cannot generalize findings to other populations of students, and it becomes unclear what intervention strategies work, especially with English language learner student populations. However, 25 studies did specifically recognize and address the needs of English language learners, indicating more researchers are taking into consideration the diverse needs of other struggling student populations.

Abstract
In this study, we tested the outcomes of access to a response to intervention (RtI) model in kindergarten or in first grade on end-of-Grade-2 reading achievement and placement in special education. Across five schools, 214 students who began having access to Tier 2 intervention in kindergarten or first grade were compared in Grades 1 and 2 with 208 cohort peers who were average readers and 102 historical control condition second grade poor readers who did not receive Tier 2 intervention. Results demonstrated significant effects on reading achievement for access to RtI in kindergarten at the end of first grade (effects averaged 0.48), but not in second grade, except for students who were English language learners (ELLs), who showed an advantage through the end of second grade. Students with access to RtI overall had significantly higher outcomes at the end of Grade 2 than students in the historical control, with no differences resulting from ELL status. No significant difference in the proportion of students placed in special education was noted; however, a greater proportion of the students found eligible as with learning disabilities had poor reading scores if they were placed after participating in RtI.

Abstract
This article describes a randomized controlled trial conducted to evaluate the effects of an intensive, individualized, Tier 3 reading intervention for second grade students who had previously experienced inadequate response to quality first grade classroom reading instruction (Tier 1) and supplemental small-group intervention (Tier 2). Also evaluated were cognitive characteristics of students with inadequate response to intensive Tier 3 intervention. Students were randomized to receive the research intervention (N = 47) or the instruction and intervention typically provided in their schools (N = 25). Results indicated that students who received the research intervention made significantly better growth than those who received typical school instruction on measures of word identification, phonemic decoding, and word reading fluency and on a measure of sentence- and paragraph-level reading comprehension. Treatment effects were smaller and not statistically significant on phonemic decoding efficiency, text reading fluency, and reading comprehension in extended text. Effect sizes for all outcomes except oral reading fluency met criteria for substantive importance; however, many of the students in the intervention continued to struggle. An evaluation of cognitive profiles of adequate and inadequate responders was consistent with a continuum of severity (as opposed to qualitative differences), showing greater language and reading impairment prior to the intervention in students who were inadequate responders.

Abstract
Based on challenges with the traditional model of school psychology, response to intervention (RTI) has been advanced as a model of special education eligibility decision making and service delivery that may address the drawbacks of the traditional models of assessment and result in improved outcomes for students. In this article, the RTI model is described, and the research base describing its rationale and outcomes is reviewed. Finally, a description of how RTI has been and can continue to be adopted and researched in Canada is provided.

Abstract
In 2007, the New Zealand Ministry of Education formally recognized the condition of dyslexia for the first time and has subsequently developed a working definition of the condition. The aim of this article is to draw on contemporary theory and research on reading development, reading difficulties, and reading intervention to describe what the authors believe are four key components of a definition of dyslexia/reading disability.They begin by discussing some preliminary factors that need to be considered in developing a definition of dyslexia. The authors then present the four components of their proposed definition, drawing on a framework for conceptualizing reading difficulties derived from the simple view of reading. They conclude by comparing their definition of dyslexia with the working definition put forward by the ministry.

Abstract
Purpose
This study assessed the effectiveness of a Tier 2 intervention that was designed to increase the phonemic awareness skills of low-income preschoolers who were enrolled in Early Reading First classrooms.
Method
Thirty-four preschoolers participated in a multiple baseline across participants treatment design. Tier 2 intervention for beginning sound awareness was provided twice weekly in small groups over 6 weeks by trained teachers and speech-language pathologists (SLPs).
Results
The intervention was successful for 71% of the children, as indicated by medium to large effect sizes. Comparisons between children who did and did not qualify for intervention suggest that Tier 2 intervention helped narrow the gap in beginning sound awareness that had begun to emerge before treatment. Although children receiving special education and those learning English as a second language were enrolled in the classrooms, they were not overrepresented in the group qualifying for Tier 2 intervention, and most who did qualify demonstrated a positive response to intervention.
Conclusion
In a relatively short period of time, preschoolers' phonemic awareness skills were increased through small-group Tier 2 intervention provided by teachers and SLPs. Findings indicate the potential of Tier 2 interventions to positively impact the future reading skills of children who are at risk for later reading difficulties.

Abstract
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) evidence in support of DT/A and RTI, and (f) expectations associated with each of the concepts. The main outcome of this comparison is a conclusion that both approaches belong to one family of methodologies in psychology and education whose key feature is in blending assessment and intervention in one holistic activity. Because DT/A has been around much longer than RTI, it makes sense for the proponents of RTI to consider both the accomplishments and frustrations that have accumulated in the field of DT/A.

Abstract
Response to intervention (RTI) holds great promise for the early identification and prevention of reading disabilities. The success of RTI rests in part on the accuracy of universal screening tools used within this framework. Despite advancements, screening instruments designed to identify children at risk for reading disabilities continue to have limited predictive validity. In this study, the authors examined a common screening instrument for the presence of floor effects and investigated the impact that these effects have on the predictive validity of the instrument. Longitudinal data (kindergarten to third grade) from a large cohort of children were used. These data included children's performance on five measures from the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) and two reading achievement outcome measures. The results showed that DIBELS measures were characterized by floor effects in their initial administrations and that these effects reduced the predictive validity of the measures. The implications of these findings for early identification are discussed.

Abstract
In this study, response to intervention and stability of reading performance of 41 kindergarten children identified as at risk of reading difficulty were evaluated from kindergarten through third grade. All students were assessed in the fall of each academic year to evaluate need for intervention, and students who fell below the 30th percentile on criterion measures received small-group supplemental intervention. Measures included a combination of commercial normative referenced measures and specific skill and construct measures to assess growth or change in reading risk status relative to 30th percentile benchmarks. Results indicated that consistent with the findings of prior research involving students with comparable entry-level performance, the majority of children identified as at risk in the beginning of kindergarten responded early and positively to intervention. On average, absolute performance levels at the end of kindergarten positioned students for trajectories of later reading performance that exceeded the 50th percentile on the majority of measures. Moreover, changes in risk status that occurred early were generally sustained over time. Only oral reading fluency performance failed to exceed the 30th percentile for the majority of students.
