We review published single subject design (SSD) studies that examine the effects of interventions for English learners at‐risk or with learning disabilities. Results of our literature search yielded 10 studies, five in reading, one in reading and behavior, and four in mathematics that met our inclusion criteria. Seven studies targeted Spanish‐speaking English learners, and three studies included students who spoke other languages than English and/or English only students. Two studies in mathematics included native language instruction. Six studies included English learners in second grade and above, and one study included high school students. We were able to calculate effect sizes (Hedges g) for eight of the 10 studies. Findings indicated a significant effect of the intervention for 12 of the 18 dependent variables measured. SSD methodology has the potential to help researchers and practitioners better understand what interventions work for English learners, and under what circumstances.  相似文献

Two studies were conducted to examine the effects of Tier 2 and Tier 3 mathematics interventions on students with mathematics learning difficulties. In the first study, the work of Bryant et al. was replicated and expanded upon by documenting the sustained effects of a Tier 2 mathematics intervention on mathematics performance by second graders. In the second study, the Tier 2 intervention was intensified to a Tier 3 intervention through increases in two instructional features: group size and dosage. The results of the first study showed that the Tier 2 intervention improved mathematics performance for the majority of student participated in the study, and the effect of the intervention was sustained for the majority of students who responded to the Tier 2 intervention. The results of the second study showed that intensified Tier 3 intervention that involved one‐on‐one instruction and extended time for daily lessons may benefit students who have persistent difficulties with learning mathematics.  相似文献

ABSTRACT

Over the past decades, there has been a significant increase in the use of computers and mobile devices in schools as part of mathematics instruction for students with learning disabilities (LD). The purpose of this synthesis was to provide a systematic review of the research on the effects of computer-assisted instruction (CAI) for both computers and mobile devices when teaching mathematics to students with LD. Twenty studies met the selection criteria that were published between 1980 and 2017. Findings revealed a wide range of effect sizes across the studies, but in general, the results represent a medium intervention effect and a large maintenance effect of using CAI for students with LD on their mathematics progress. In addition, findings revealed a relationship between the number of evidence-based instructional variables embedded in the CAI instruction and the effect on student performance. Overall, results indicated that well designed CAI with effective instructional variables should be considered as a promising intervention to support mathematics instruction for students with LD.  相似文献

This investigation examined the impact of preintervention word-reading ability on reading comprehension outcomes for ninth graders with learning disabilities, reading difficulties, and English learners in treatment and comparison conditions. Secondary data analyses were conducted for two separate but related experimental studies of intensive reading interventions. Both studies provided yearlong intensive reading interventions to ninth graders. The study included replication of a post hoc analysis employed in a previous study of ninth graders who also received 1 year of intervention. Results from both studies demonstrated that the effects of treatment were not moderated by decoding level for reading comprehension. Statistically significant effects of verbal ability were found. These findings suggest the effectiveness of intervention and that higher verbal skills improve students’ comprehension, though the effects were more pronounced for Study One than Study Two.  相似文献

As classrooms begin to adopt a greater number of digital technologies such as computers and tablets, it is important for educators to understand how effective such tools can be in aiding in the delivery of instruction to students who struggle in mathematics, such as those identified with a learning disability in mathematics. One digital‐based instructional strategy with a limited research base for students with a learning disability is video modeling. Through a single subject alternating treatments design, this study compared the use of video modeling to face‐to‐face explicit instruction for teaching geometry word problems to three secondary students with a learning disability in mathematics. Across 10 sessions of intervention, all three students demonstrated improved performance on all dependent variables with both interventions, while the explicit instruction condition produced slightly greater accuracy scores for two of the three students. The results and their implications for the field of mathematics are discussed.  相似文献

This article quantitatively summarizes experimental and quasi‐experimental studies on teaching students with mathematics difficulties (MD) published between 2000 and 2014, research that was available following earlier syntheses. It reports the analysis of effect sizes of 25 intervention studies on participant characteristics, intervention parameters, domains of mathematics interventions, and instructional approaches and components. Results indicate that several participant characteristics (e.g., grade level and level of mathematics difficulties) and intervention parameters (e.g., methodological soundness, intervention agent, and grouping) mediated the treatment effects. In addition, different types of instructional approaches and several instructional components contributed to the improvements in mathematics performance in students with MD.  相似文献

Abstract The purpose of this article is to provide an overview of research‐based interventions that incorporate self‐regulation strategies to improve mathematics performance of students with learning disabilities (LD). Self‐regulation is a metacognitive function essential to academic success. Students with LD are notoriously poor at self‐regulation and must be taught explicitly to monitor and control their cognitive activities as they engage in academic tasks such as mathematical problem solving. This article describes intervention studies that use self‐regulation strategies to improve mathematics performance of students with LD at the elementary, middle, and secondary school levels. Several techniques to facilitate effective implementation of self‐regulation instruction in the classroom are presented.  相似文献

The purpose of this synthesis is to summarize the effectiveness of peer‐mediated interventions on the mathematics performance of both students with disabilities and those at risk for mathematics disabilities. Meta‐analytic techniques were used to calculate mean effect sizes for 17 studies that met inclusion criteria. Results indicate that peer‐mediated interventions in mathematics are moderately effective for improving students' mathematics performance. Also, findings are strongest for students at risk for mathematics disabilities, elementary‐aged participants, and mathematics computation content. Recommendations for future research and practical implications are discussed.  相似文献

This study investigated the impact of cognitive strategy instruction (CSI) on mathematical word problem solving of students with mathematics disabilities. A sample of fourth-grade students in a Chinese primary school was divided into a treatment group (75 students) and a comparison group (75 students). The sample consisted of students with mathematics disabilities only, students with both mathematics and reading disabilities, as well as average- and high-achieving students. Results showed that students at all ability levels (except high-achieving students) in the treatment group outperformed significantly their counterparts in the comparison group; the intervention effect was stronger for students with mathematics disabilities only than for those with both mathematics and reading disabilities. The present study indicates that CSI is a contextually and pedagogically appropriate model that has a strong potential to improve mathematical word problem solving.  相似文献

The purpose of this article is to describe features of interventions that are empirically validated for use with first‐grade students at risk for reading disabilities who are English language learners (ELLs) and whose home language is Spanish. The empirical evidence supporting these interventions is summarized. Interventions for improving oral language and reading abilities with struggling readers who are ELLs taught in either Spanish or English are described as a means to assist school districts and teachers in defining and implementing effective interventions for ELLs at risk for reading difficulties. The interventions described may be useful to educators seeking information about Response to Intervention as a means of identifying ELLs who require services for learning disabilities.  相似文献

Responsiveness to intervention (RTI) is an innovative approach to the identification of learning disabilities (LD). The central assumption is that RTI can differentiate between two explanations for low achievement: poor instruction versus disability. If the child responds poorly to validated instruction, then the assessment eliminates instructional quality as a viable explanation for poor academic growth and instead provides evidence of a disability. For children who do respond nicely, RTI serves a critical prevention function. Most of RTI research has been focused on early reading. In this article, we describe two ongoing programs of research on RTI in the area of mathematics: one on a comprehensive mathematics curriculum at first grade and the other focused on word problems at third grade. For each research program, we describe the sample, explain how students are identified as at risk for mathematics disability, provide an overview of the interventions to which responsiveness is gauged, and describe some results to date.  相似文献

Middle school students with learning disabilities often struggle with reading and literacy skills, including vocabulary, and require support in content-area classes such as mathematics where weak vocabulary knowledge can negatively affect learning, achievement, and deep understanding. However, in general, middle school mathematics teachers do not receive training in literacy instruction, much less in explicit vocabulary instruction. Additionally, relatively few studies have examined content-area vocabulary instruction at the middle or secondary school level. This study addressed these gaps in the research by examining the effect of a performance feedback and coaching intervention on middle school mathematics teachers’ use of explicit mathematics vocabulary instruction. Results of the study indicate that performance feedback and coaching had moderately positive effects on teachers’ use and quality of explicit mathematics vocabulary instruction.  相似文献

Students who demonstrate persistent mathematics difficulties and whose performance is severely below grade level require intensive intervention. Intensive intervention is an individualized approach to instruction that is more demanding and concentrated than Tier 2 intervention efforts. We present the elements of intensive intervention that teachers should consider when planning for, implementing, and monitoring intensive intervention in mathematics. Each of these elements is based on evidence from validated interventions. We also highlight strategies for intensifying instruction. We provide two examples of intensive intervention, one of which launches from a Tier 2 intervention platform and the other which is completely generated by a teacher. We conclude with considerations for intensive intervention in mathematics.  相似文献

The purpose of this study was to examine whether English language learners (ELLs) would increase their vocabulary scores in the areas of word recognition, word meaning, and word application when iPads were used during vocabulary instruction. Five third-grade ELLs, at risk of being diagnosed as having learning disabilities, participated in the study. All students demonstrated low test scores in learning vocabulary words during the baseline. During the intervention, 36 vocabulary words selected from the third-grade’s Dolch word list were taught and practiced using the iPad application Learning Touch, First Sight Words Pro. All students were assessed and their vocabulary scores increased in the areas of word recognition, word meaning, and word application. Using the iPad and iPad app appears to provide a potential avenue for ELLs in learning English vocabulary words.  相似文献

The premise of a great deal of current research guiding policy development has been that accommodations are the catalyst for student performance differences. Rather than accepting this premise, two studies were conducted to investigate the influence of extended time and content knowledge on the performance of ninth‐grade students who took a statewide mathematics test with and without accommodations. Each study involved 1,250 accommodated students (extended time only) with learning disabilities and 1,250 nonaccommodated students demonstrating no disabilities. In Study One, a standard differential item functioning (DIF) analysis illustrated that the usual approach to studying the effects of accommodations contributes little to our understanding of the reason for performance differences across students. Next, a mixture item response theory DIF model was used to explore the most likely cause(s) for performance differences across the population. The results from both studies suggest that students for whom items were functioning differently were not accurately characterized by their accommodation status but rather by their content knowledge. That is, knowing students' accommodation status (i.e., accommodated or nonaccommodated) contributed little to understanding why accommodated and nonaccommodated students differed in their test performance. Rather, the data would suggest that a more likely explanation is that mathematics competency differentiated the groups of student learners regardless of their accommodation and/or reading levels.  相似文献

This article focuses on the cognitive factors that impact on students in the middle school years experiencing learning difficulties in basic mathematics. It begins with a review of selected literature providing information about the learning difficulties in mathematics. Focus then shifts to an implementation of the QuickSmart intervention. QuickSmart is a basic academic skills intervention designed for persistently low-achieving middle-years' students. In this small-scale study, 12 middle school students experiencing learning difficulties participated in the QuickSmart mathematics program. Comparisons are made between the mathematics progress of the intervention group and eight average-achieving peers. The results indicate that on measures of response speed and accuracy QuickSmart participant students were able to narrow the gap between their performance and that of their average-achieving peers. Further, on standardized tests of more general mathematical knowledge, participant students improved significantly from pre-test to post-test. Implications are drawn regarding the importance of interventions that emphasize automaticity in basic mathematics for middle years students with learning difficulties.  相似文献
