A previous meta-analysis indicated that eight instructional factors--Questioning, Sequencing and Segmentation, Skill Modeling, Organization and Explicit Practice, Small-Group Setting, Indirect Teacher Activities (e.g., homework), Technology, and Scaffolding-captured the majority of successful intervention programs for adolescents with learning disabilities (LD). Most important was the Organization/Explicit factor, which contributed significant variance (16%) to effect size. This factor included two important instructional components: advance organization and explicit practice. In this article, we convert these findings into practical guidelines to direct instructional practice.  相似文献

The present article provides a meta-analysis of instructional research with samples of children and adolescents with learning disabilities in the domains of word recognition and reading comprehension. The results of the synthesis showed that a prototypical intervention study has an effect size (ES) of .59 for word recognition and .72 for reading comprehension. Four important findings emerged from the synthesis: (a) Effect sizes for measures of comprehension were higher when studies included derivatives of both cognitive and direct instruction, whereas effect sizes were higher for word recognition when studies included direct instruction; (b) effect sizes related to reading comprehension were more susceptible to methodological variation than studies of word recognition; (c) the magnitude of ES for word recognition studies was significantly related to samples defined by cutoff scores (IQ > 85 and reading < 25th percentile), whereas the magnitude of ES for reading comprehension studies was sensitive to discrepancies between IQ and reading when compared to competing definitional criteria; and (d) instructional components related to word segmentation did not enter significantly into a weighted least square hierarchical regression analysis for predicting ES estimates of word recognition beyond an instructional core model, whereas small-group interactive instruction and strategy cuing contributed significant variance beyond a core model to ES estimates of reading comprehension. Implications related to definition and instructional components that optimize the magnitude of outcomes are discussed.  相似文献

Thirty years of intervention research on the effects of reading comprehension strategies for students with learning disabilities was reviewed in this quantitative synthesis. Specifically, researchers targeted studies that contained self‐regulated learning components. A systematic search yielded 18 studies from nine research journals that met specified inclusion criteria. Studies were evaluated for methodological quality and to identify types of instructional and self‐regulation components within interventions. Large effect sizes were found immediately after instruction and after a time delay, suggesting that instruction in reading comprehension strategies that contain self‐regulation components may have a long lasting impact on student performance. Implications for research and practice are discussed.  相似文献

This article summarizes single-subject-design intervention studies that include students with learning disabilities. Effect sizes of 85 studies were analyzed across instructional domains (e.g., reading, mathematics); sample characteristics (e.g., age, intelligence); intervention parameters (e.g., number of instructional sessions, instructional components); and methodological procedures (e.g., internal validity, treatment integrity, sample representation). The major findings were as follows: (a) All domain areas except handwriting yielded effect sizes at or above Cohen's .80 threshold for a substantial finding; (b) instructional components related to drill-repetition-practice-review, segmentation, small interactive groups, and the implementation of cues to use strategies contributed significant variance (15%) to estimates of effect size; (c) strategy instruction (SI) models better predicted effect size estimates than direct instruction (DI) models when the results were qualified by the reported intellectual and reading levels of the participants; (d) high-IQ discrepancy groups yielded lower effect sizes compared to low-IQ discrepancy groups in the domain of reading, whereas the reverse effect occurred when treatment outcomes were not reading measures; and (e) the low-IQ discrepancy groups yielded higher effect sizes for a Combined DI and SI Model when compared to competing models. The results are supportive of the pervasive influence of cognitive strategy and direct instruction models across treatment domains and of the notion that variations in sample definition moderate treatment outcomes.  相似文献

This article presents a systematic review of the literature for studies that utilized computer‐based graphic organizers for students with learning disabilities. A comprehensive search yielded 12 studies that were coded and analyzed. The authors investigated the effectiveness of the treatments on academic outcomes, and selected integral instructional and methodological features for evaluation in order to delineate practical implications and prioritize future research. Findings revealed high effect sizes on social studies measures and encouraging results for written expression, while comprehension results were less promising. This review found no evidence suggesting that these treatments were efficacious without the use of explicit instruction and guided practice.  相似文献

This study examined the effects of a multicomponent social communication intervention to promote language learning and peer‐directed social interactions in preschool children with disabilities. Participants were eight children with developmental disabilities who met the specified criteria for the study. The intervention consisted of three components: (a) a planning period for instructional purposes, (b) a play session to practice skills, and (c) a brief reporting period to review skill performance. A multiple baseline design across two dyads replicated across two additional dyads was used. Results indicated an increase in peer‐directed requests, verbal requests, and word diversity for 6 of the 8 participants postintervention. Implications of the results are discussed. © 2008 Wiley Periodicals, Inc.  相似文献

The Common Core State Standards for literacy in history and social studies present opportunities and challenges for teachers of and adolescents with learning disabilities (LD). In addition to reading challenges, students must engage in higher order thinking and reasoning. To provide opportunities for students to successfully respond to such challenges, teachers must have an understanding of the expectations in the Standards, and of the learning needs of students with LD. Teachers can assure success for adolescents with LD by selecting proven instructional procedures and engaging in collaboration to provide students with the supports they need. Examples of one evidence‐based practice, Content Enhancement, are provided to illustrate instructional protocols for teachers of diverse classes that include adolescents with LD.  相似文献

The Lesson Study for Accessible Science (LSAS) project created middle school teams comprised of both science and special education teachers who engaged in collaborative work to improve instruction in inclusive classrooms. The intervention is based on Lesson Study, a professional development approach that originated in Japan, which supports the systematic examination of practice and student understanding. Using an experimental design, teams of teachers were randomly assigned to the LSAS intervention or to a wait‐list comparison group. The results of this study suggest that science and special educators in the LSAS intervention were able to generate more accommodations for students with learning disabilities, and they increased their ability to set an instructional context and adapt an instructional plan to meet science learning goals for all students in an inclusive classroom. They did not, however, show significant increases in their knowledge of science content or learning disabilities. © 2012 Wiley Periodicals, Inc. J Res Sci Teach 49: 1012–1034, 2012  相似文献

This article synthesizes the experimental literature on reading interventions for upper elementary and middle school students identified with reading disabilities on norm‐referenced reading measures. Ten studies (12 independent samples) yielded 70 effect sizes on norm‐referenced reading measures with an aggregated mean of 0.41 (SE= .04) in favor of the experimental condition. Moderate effect sizes emerged on norm‐referenced measures of word identification (M= 0.41), decoding (M= 0.43), and comprehension (M= 0.73) and low effect sizes for fluency (M=–.29). Intervention outcomes did not significantly vary as a function of the reading skills measured, type of reading instruction, and/or variations in sample characteristics. Studies yielding low and relatively moderate effect sizes shared a number of instructional components. Overall, the magnitude of the results for experimental reading intervention studies for students with reading disabilities in the middle school age range was small to moderate. Implications of the study were discussed.  相似文献

Sixty children with severe reading disabilities were randomly assigned to two instructional programs that incorporated principles of effective instruction but differed in depth and extent of instruction in phonemic awareness and phonemic decoding skills. All children received 67.5 hours of one-to-one instruction in two 50-minute sessions per day for 8 weeks. Both instructional programs produced very large improvements in generalized reading skills that were stable over a 2-year follow-up period. When compared to the growth in broad reading ability that the participants made during their previous 16 months in learning disabilities resource rooms, their growth during the intervention produced effect sizes of 4.4 for one of the interventions and 3.9 for the other. Although the children's average scores on reading accuracy and comprehension were in the average range at the end of the follow-up period, measures of reading rate showed continued severe impairment for most of the children. Within 1 year following the intervention, 40% of the children were found to be no longer in need of special education services. The two methods of instruction were not differentially effective for children who entered the study with different levels of phonological ability, and the best overall predictors of long-term growth were resource room teacher ratings of attention/behavior, general verbal ability, and prior levels of component reading skills.  相似文献

Marking major changes in professional role performance, response to intervention (RTI) is now in the Individuals with Disabilities Education Act (IDEA, 2004) as a possible method to improve the identification of specific learning disabilities. Moreover, RTI and related concepts and initiatives have fundamentally influenced more general methods of prevention, instruction and intervention services, and decision making in schools. Although RTI will continue to evolve, core characteristics of RTI that form the basis of state initiatives are well founded in intervention and instructional research and practice. These core characteristics (i.e., data‐based decision making, evidence‐based intervention, teaming, and problem solving) represent skills immediately needed by professionals‐in‐training. This article reports collaboration between school psychology and special education faculty in designing and implementing an integrative field experience in RTI. Training, student, and program outcomes are used summatively for accountability. © 2008 Wiley Periodicals, Inc.  相似文献

Abstract. The complex nature of written expression presents difficulty for many students, particularly those with learning disabilities (LD). The literature in the area of written expression and students with learning disabilities indicates that explicit, rule‐based instruction can enhance the writing skills of struggling students. Research in Direct Instruction (DI) writing programs is promising, but limited at this time to a small number of group design studies. The purpose of this study was to investigate the effects of the DI writing program, Expressive Writing, for high school students with learning disabilities using a single‐subject design methodology. Results indicated that the Expressive Writing program improved the writing skills of the students in this study. Students also were able to generalize and maintain the writing skills learned during intervention.  相似文献

In this intervention study, teachers tried to implement four instructional principles derived from the literature on research-based, explicit reading comprehension instruction in their fifth-grade classrooms. The principles focused on relevant background knowledge, reading comprehension strategies, reading-group organization, and reading motivation. Results indicated that during a five-month intervention period, students in the intervention group increased their strategic competence and comprehension performance relative to controls. However, no effect was found on reading motivation. The overall pattern of results is explained in relation to the implementation quality of the four instructional principles, with implementation data indicating that the principles of reading-group organization and reading motivation were particularly difficult for the teachers to translate into classroom practice.  相似文献

Although science has received much attention as a political and educational initiative, students with learning disabilities (LD) perform significantly lower than their nondisabled peers. This meta‐analysis evaluates the effectiveness of instructional strategies in science for students with LD. Twelve studies were examined, summarized, and grouped according to the type of strategy implemented. Effect sizes (ES) were calculated for each study. Across all studies, a mean ES of .78 was obtained, indicating a moderate positive effect on students with LD science achievement. Findings also align with past reviews of inquiry‐based instruction for students with special needs, indicating that students with LD need structure within an inquiry science approach in order to be successful. Additionally, results suggest that mnemonic instruction is highly effective at increasing learning disabled students' acquisition and retention of science facts.  相似文献

The Common Core State Standards and the continued inclusion of students with learning disabilities (LD) in Tier 1 classrooms are changing how close reading of texts occurs in English Language Arts classrooms. Therefore, understanding the potential impact of literacy‐related evidence‐based practices during Tier 1 instruction that includes students with reading‐related disabilities is essential. This article reviews the research on story‐structure instruction for students with LD and at‐risk for failure. Findings across 16 studies indicate several features of strong methodological designs including random assignment and inclusion of students with LD. However, substantial limitations in the research base include contradictory outcomes, limited outcomes disaggregated for students with LD, reliance on researcher‐developed measures, a lack of instructional features to support students with LD, and limited features of feasible implementation.  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

The changing job market requires a sophisticated array of literacy skills that adolescents with learning disabilities reading below grade level have not yet acquired. This summary of the research on reading comprehension highlights emerging findings and related instructional conditions necessary to achieve optimal student outcomes with limited instructional time. Limitations in the existing evidence base are addressed via four factors for future research and development agendas: (a) use theory to inform research and practice, (b) study the role that dosage plays as an independent variable, (c) study tiered models of instruction that are applicable for use in middle and high school settings, and (d) study factors that can enhance scaling of reading comprehension interventions.  相似文献

Improving the algebraic concepts and skills of secondary school students with learning disabilities is critical for their success in college and in the job market. This research reviewed 12 studies to examine interventions for students with learning disabilities in relation to algebraic notions and competencies. The results indicate that in regard to the Common Core State Standards for Mathematics (CCSSM) Content Standards, the majority of the studies address linear equations and expressions, linear inequalities, and quadratic expressions; they show that following interventions, students’ performance improved with respect to algebraic concepts and skills. The Tau-U and Hedges’ g of the intervention effects computed were typically large or very large. The most commonly used instructional components in the interventions were multiple representations, a sequence and/or range of examples, and explicit instruction. Limitations and suggestions for future research are discussed.  相似文献

This study was an investigation into the effectiveness of a color‐coded, onset‐rime–based decoding intervention with first‐graders at serious risk for reading disabilities using a single‐subject multiple probe design. Students increased their ability to decode instructional words on average 73% over baseline. For novel words from instructed rime patterns, scores increased by an average of 56%. Transfer at the vowel level to uninstructed rime patterns was limited, with scores improving by an average of 29%. Students maintained decoding gains at 1‐week and 1‐month maintenance. While acknowledging the difficulty in predicting reading disabilities based on first‐grade performance, the effectiveness of the early intervention is a promising step in finding an instructional approach that is successful with the most at risk or disabled students who often do not respond to effective remedial programs.  相似文献

Students with disabilities often struggle with writing tasks. In order to improve the written expression performance of high school students with deficits in written expression, a Direct Instruction writing program was implemented. The participants were six high school students in programs for individuals with learning disabilities. Three of the six students were served in programs for students who are English Language Learners. Using a multiple‐probe across‐participants design, the effect of the writing program was examined. The intervention was implemented over a 5‐week period with maintenance checks conducted 2 and 4 weeks after the termination of instruction. Results were variable, but there appeared to be a positive trend in student writing performance as measured by correct word sequence, length of text, and the TOWL‐3. Implications for practice and future directions are also provided.  相似文献
