Over the past decade, parent advocacy groups led a grassroots movement resulting in most states adopting dyslexia-specific legislation, with many states mandating the use of the Orton-Gillingham approach to reading instruction. Orton-Gillingham is a direct, explicit, multisensory, structured, sequential, diagnostic, and prescriptive approach to reading for students with or at risk for word-level reading disabilities (WLRD). Evidence from a prior synthesis and What Works Clearinghouse reports yielded findings lacking support for the effectiveness of Orton-Gillingham interventions. We conducted a meta-analysis to examine the effects of Orton-Gillingham reading interventions on the reading outcomes of students with or at risk for WLRD. Findings suggested Orton-Gillingham reading interventions do not statistically significantly improve foundational skill outcomes (i.e., phonological awareness, phonics, fluency, spelling; effect size [ES] = 0.22; p = .40), although the mean ES was positive in favor of Orton-Gillingham-based approaches. Similarly, there were not significant differences for vocabulary and comprehension outcomes (ES = 0.14; p = .59) for students with or at risk for WLRD. More high-quality, rigorous research with larger samples of students with WLRD is needed to fully understand the effects of Orton-Gillingham interventions on the reading outcomes for this population.

Because of the importance of teaching reading comprehension to struggling young readers and the infrequency with which it has been implemented and evaluated, we designed a comprehensive first-grade reading comprehension program. We conducted a component analysis of the program's decoding/fluency (DF) and reading comprehension (COMP) dimensions, creating DF and DF+COMP treatments to parse the value of COMP. Students (N = 125) were randomly assigned to the 2 active treatments and controls. Treatment children were tutored 3 times per week for 21 weeks in 45-min sessions. Children in DF and DF+COMP together performed more strongly than controls on word reading and comprehension. However, pretreatment word reading appeared to moderate these results such that children with weaker beginning word reading across the treatments outperformed similarly low-performing controls to a significantly greater extent than treatment children with stronger beginning word reading outperformed comparable controls. DF+COMP children did not perform better than DF children. Study limitations and implications for research and practice are discussed.

This study examined how differences in listening comprehension and word reading at the beginning of the school year influence changes in reading comprehension for English learners (ELs) with significant reading difficulties compared to non-ELs with significant reading difficulties. The study investigated heterogeneity in response to instruction among 400 struggling readers in fourth grade (n = 183 for non-EL; n = 217 for EL) who received an intensive reading intervention. At pretest, word reading, listening comprehension, and reading comprehension were measured, and at posttest, reading comprehension was measured again. Results from moderated multiple regression analyses showed a significant three-way interaction such that reading comprehension at posttest was higher for ELs than non-ELs with similar levels of low word reading but relatively higher levels of listening comprehension. However, non-ELs outperformed ELs with similar levels of relatively high word reading and average to high listening comprehension. The findings suggest that pre-intervention skill profiles may need to be interpreted differently for ELs and non-ELs with significant reading difficulties in relation to language and literacy outcomes.

The purpose of this analysis was to assess whether effects of 1^st-grade mathematics intervention apply across the range of at-risk learners' initial skill levels. Students were randomly assigned to control (n=213) and 2 variants of intervention (n=385) designed to improve arithmetic. Of each 30-minute intervention session (48 over 16 weeks), 25 minutes were identical in the 2 variants, focused on number knowledge that provides the conceptual bases for arithmetic. The other 5 minutes provided non-speeded conceptual practice (n=196) or speeded strategic practice (n=199). Contrasts tested effects of intervention (combined across variants) versus control and effects between the variants. Moderation analysis indicated no significant interactions between at-risk children's pre-intervention mathematics skill and either contrast on any outcome. Across pre-intervention math skill, effects favored intervention over control on arithmetic and transfer to double-digit calculations and number knowledge and favored speeded over non-speeded practice on arithmetic.

Nonmainstream American English, or dialect, among children may have important implications for reading research and practice. However, much of the research involving relations between dialect and literacy has analyzed dialect use in only one context and has omitted students with speech, language, and learning disabilities. Consequently, we examined dialect use in an oral narrative and two writing samples in relation to concurrent and longitudinal reading outcomes in a diverse sample of students, including those with diagnosed disabilities. Overall, most students used features of dialect in oral and written language. Dialect use was significantly and negatively predictive of reading outcomes the same year and 2 years later. Moderator analyses indicated a similar relationship between dialect use and reading for students with speech, language, and learning disabilities, suggesting that students with these disabilities who also use dialect may be at increased risk for reading difficulties. Implications for practice and future research are provided.

Combining data from a series of three planned, consecutive independent randomized controlled trials (RCTs), the present study investigates two literacy interventions for preschool children with autism spectrum disorder (ASD). For the first cohort, children were randomized to interactive book reading treatment (IBR)or a business-as-usual (BAU) control condition; in Cohort 2, children were randomized to phonological awareness treatment (PA)or BAU; in Cohort 3, children were randomized to IBR or PA. Both treatments were implemented weekly in the classroom from November to May. Combined across cohorts, data from n =47 IBR, n =42 PA, and n =44 BAU students from 57 classrooms in 8 districts were available for analysis. Model results showed that IBR had significantly greater pretest-posttest gains than the sample mean on expressive vocabulary and listening comprehension (d*=0.29 and 0.30), whereas PA had significantly greater phonological awareness gains (d*=0.39).

Teacher stress and burnout have a detrimental effect on the stability of the teaching workforce. However, the possible consequences of teacher burnout on teaching quality and on student learning outcomes are less clear, especially in special education settings. We applied Maslach and Leiter's model (1999) to understand the direct effects of burnout on teaching in general and stress arising from interaction with a specific student on the IEP outcomes of young children with autism spectrum disorder. We also examined indirect effects through teaching quality and student engagement. The results indicated that one of the three components of burnout-teacher personal accomplishment-was directly related to IEP outcomes, a distal effect, whereas stress was directly related to teaching quality and student engagement, which were more proximal effects. Additionally, teacher stress, emotional exhaustion, and depersonalization had indirect effects on IEP outcomes through teaching quality and student engagement.

We identified child-level predictors of responsiveness to 2 types of mathematics (calculation and word-problem) intervention among 2nd-grade children with mathematics difficulty. Participants were 250 children in 107 classrooms in 23 schools pretested on mathematics and general cognitive measures and posttested on mathematics measures. We assigned classrooms randomly assigned to calculation intervention, word-problem intervention, or business-as-usual control. Intervention lasted 17 weeks. Path analyses indicated that scores on working memory and language comprehension assessments moderated responsiveness to calculation intervention. No moderators were identified for responsiveness to word-problem intervention. Across both intervention groups and the control group, attentive behavior predicted both outcomes. Initial calculation skill predicted the calculation outcome, and initial language comprehension predicted word-problem outcomes. These results indicate that screening for calculation intervention should include a focus on working memory, language comprehension, attentive behavior, and calculations. Screening for word-problem intervention should focus on attentive behavior and word problems.
