Evidence‐Based Strategies for Reading Instruction of Older Students with Learning Disabilities

Over a quarter of 8th‐grade students and more than one‐third of 4th graders do not read well enough to understand important concepts and acquire new knowledge from grade‐level text. For students with learning disabilities, the numbers are more troubling. This article describes features of evidence‐based instruction for students who continue to struggle with reading in late elementary, middle, and high school. Recommendations are organized into 5 areas that are critical to the reading improvement of older struggling readers: (1) word study, (2) fluency, (3) vocabulary, (4) comprehension, and (5) motivation. Much of the content in this article reflects our efforts with the Special Education and Reading Strands at the National Center on Instruction, funded by the Office of Special Education Programs and the Office of Elementary and Secondary Education. Two reports, both available at http://www.centeroninstruction.org/ , have particular relevance—Interventions for Adolescent Struggling Readers: A Meta‐Analysis with Implications for Practice and Academic Literacy Instruction for Adolescents: A Guidance Document from the Center on Instruction.     

Evidence‐Based Strategies for Improving the Reading Comprehension of Secondary Students: Implications for Students with Learning Disabilities

Reading comprehension is a complex skill that places significant demands on students, beginning with elementary school and continuing through the secondary grades. In this article, we provide an overview of possible factors associated with problems in reading comprehension among secondary students with learning disabilities. Discussion underscores the fact that comprehension problems are evidenced by a heterogeneous group of students. We argue that it is important for teachers to align an intervention with a specific area of difficulty (e.g., teaching prefixes and suffixes to increase reading vocabulary). We highlight research‐based interventions advocated by the National Reading Panel and offer ways that teachers can match specific strategies with the individual needs of students with problems in reading comprehension. Finally, we emphasize that whatever strategy is selected, it should be structured, explicit, scaffolded, and intense ( Williams et al., 2005 ).     

Taking the Guesswork out of Locating Evidence‐Based Mathematics Practices for Diverse Learners

Legislations mandates that educators use evidence‐based practices (EBPs) that are supported by scientifically based research. EBPs have demonstrated a likelihood to work for students with disabilities. EBPs should match targeted needs of the student receiving the instruction, which sometimes requires educators to search for the best intervention to meet specific student needs. This article discusses the impetus for practices supported by evidence, where to find interventions and strategies, and what to do when targeted interventions do not exist. Additionally, this article emphasizes the need to evaluate effectiveness of intervention at the student level.     

A Follow‐Up of Mathematics Interventions for Secondary Students with Learning Disabilities

Abstract This article extends a previous review of the literature ( Maccini & Hughes, 1997 ) on mathematics interventions for secondary school students with learning disabilities (LD). A systematic review of the literature from 1995 to 2006 yielded 23 articles that met the criteria for inclusion. It was determined that a number of practices demonstrated significant gains for secondary school students with LD in math, including mnemonic strategy instruction, graduated instructional approach, cognitive strategy instruction involving planning, schema‐based instruction, and contextualized videodisc instruction. We also discuss the nature and focus of math interventions and implications for both research and practice based on the findings.     

The Effect of Visual‐Chunking‐Representation Accommodation on Geometry Testing for Students with Math Disabilities

Students who struggle with learning mathematics often have difficulties with geometry problem solving, which requires strong visual imagery skills. These difficulties have been correlated with deficiencies in visual working memory. Cognitive psychology has shown that chunking of visual items accommodates students’ working memory deficits. This study investigated the effects of visual‐chunking representation as a testing accommodation for improving students’ geometry problem‐solving performance. Participants were four third‐graders with difficulties in mathematics. An adapted reversal design was employed to examine the students’ performance changes during standard testing conditions and accommodated testing conditions. During the accommodated condition, students were presented with visual‐chunking images. Results suggested that the visual‐chunking representation accommodation improved students’ performance on geometry problem‐solving tasks, and an interview confirmed students’ preference for the visual‐chunking representation approach.     

Using the 6S Pyramid to Identify Research‐Based Instructional Practices for Students with Learning Disabilities

To optimize students’ learning outcomes, educators are increasingly expected to use instructional practices shown to be effective by credible research. To help make this possible, organizations and scholars are producing resources that summarize research related to various instructional practices. However, as the collection of resources grows in size and complexity, it can be difficult and frustrating for practitioners to locate and utilize this information. In this article, we describe the 6S Pyramid (DiCenso, Bayley, & Haynes, 2009), a framework for efficiently and accurately prioritizing different types of research evidence. We also identify and briefly summarize Internet resources corresponding with each level of the Pyramid that can be used to identify research‐based practices for students with learning disabilities. To illustrate how the 6S Pyramid can be used in school and classroom settings, we begin and end the article with vignettes featuring a pair of co‐teachers seeking to improve instruction for their students who struggle with reading.     

Using Evidence‐Based Practices to Build Mathematics Competence Related to Conceptual,Procedural, and Declarative Knowledge

Abstract Mathematics continues to be one of the most difficult components of the school curriculum for students with learning disabilities (LD). The National Council for Teachers of Mathematics, in conjunction with current educational legislation, challenges teachers to maintain high standards for student performance in mathematics. Fortunately, over the past two decades, researchers have identified and validated a number of instructional practices that help students with LD understand and use mathematics in meaningful ways. The purpose of this article is to discuss instructional guidelines and evidence‐based practices for building conceptual, procedural, and declarative knowledge within a comprehensive mathematics curriculum. The importance of balancing these three knowledge areas across mathematics content areas is noted.     

An Investigation of Counselor Educators' Attitudes Toward Evidence‐Based Practices

Evidence‐based practices (EBPs) receive little attention in counselor education curricula despite the ethical obligation for counselor educators to teach EBPs to counseling students. This study investigates counselor educators’ attitudes toward EBPs along with perceived barriers to the inclusion of EBPs in counselor education curricula.     

Explicitly Teaching for Transfer: Effects on the Mathematical Problem‐Solving Performance of Students with Mathematics Disabilities

The purpose of this study was to explore methods to enhance mathematical problem solving for students with mathematics disabilities (MD). A small‐group problem‐solving tutoring treatment incorporated explicit instruction on problem‐solution rules and on transfer. The transfer component was designed to increase awareness of the connections between novel and familiar problems by broadening the categories by which students group problems requiring the same solution methods and by prompting students to search novel problems for these broad categories. To create a stringent test of efficacy, we incorporated a computer‐assisted practice condition, which provided students with direct practice on real‐world problem‐solving tasks. We randomly assigned 40 students to problem‐solving tutoring, computer‐assisted practice, problem‐solving tutoring plus computer‐assisted practice, or control, and pre‐ and posttested students on three problem‐solving tasks. On story problems and transfer story problems, tutoring (with or without computer‐assisted practice) effected reliably stronger growth compared to control; effects on real‐world problem solving, although moderate to large, were not statistically significant. Computer‐assisted practice added little value beyond tutoring but, alone, yielded moderate effects on two measures.     

A Systematic Review of Function‐Based Interventions for Students with Learning Disabilities

Students with learning disabilities (LD) experience pervasive academic deficits requiring extensive academic intervention; however, they may also engage in problem behaviors that adversely affect teaching and learning, thus lessening the potential impact of specialized instruction and supports. The learning deficits of students with LD are prevalent in the extant research, but behavioral needs appear to receive less attention. The authors report the results of a systematic review investigating the evidence‐base for function‐based interventions for students with LD using the What Works Clearinghouse (WWC) criteria for evaluating single‐case studies. Fourteen studies with 17 participants met inclusion criteria, with the majority occurring in elementary settings. Although interventions tended to be effective, few included maintenance and generalization measures. Because of the small number of studies (n = 4) that met WWC design and effectiveness standards, the authors conclude that function‐based interventions, although promising, cannot currently be considered an evidence‐based practice for students with LD. Implications for practice, areas for future research, and study limitations are reported.     

Fraction Instruction for Students with Mathematics Disabilities: Comparing Two Teaching Sequences

Abstract. This study investigated the effects of teaching middle school students with mathematics disabilities equivalent fraction concepts and procedures using the concrete‐representational‐abstract (CRA) instructional sequence or the representational‐abstract (RA) instructional sequence. Twenty‐six students formed the CRA group, and 24 students formed the RA group. The two treatment groups received carefully sequenced instruction over 10 lessons. The only difference between the two treatment groups was that the CRA group used concrete manipulative devices for the first three lessons while the RA group used representational drawings. Analyses of the data indicated that students in both treatment groups improved overall in their understanding of fraction equivalency from pretest to posttest. On all achievement measures, students in the CRA group had overall higher mean scores than did students in the RA group. Implications for classroom instruction and suggestions for further research are discussed.     

Math Is Not a Universal Language: Supporting Middle School Students with Learning Disabilities Using Explicit Vocabulary Instruction in Mathematics Classrooms

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.     

Science Instruction for Students with Learning Disabilities: A Meta‐Analysis

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.     

Team‐Based Learning for Students with High‐Incidence Disabilities in High School Social Studies Classrooms

We examined the effectiveness of implementing team‐based learning (TBL) practices on content acquisition for 11th grade students with high‐incidence disabilities enrolled in general education social studies courses. TBL components focus on collaborative discourse within heterogeneous teams. TBL, which requires critical thinking and the application of content knowledge for problem‐solving, was implemented for three units of instruction. Results indicated no statistically significant differences between groups on a measure of content knowledge, although a moderate effect size was noted (ES = 0.50). Significant and large effects (ES = 1.01) favoring the TBL treatment were noted for items related to content‐area vocabulary. There were no significant differences on items measuring comprehension of historical events, facts, and issues (ES = 0.38). Practical implications for content‐area instruction are discussed.     

Math,Science, and Foreign Language: Evidence‐Based Accommodation Decision Making at the Postsecondary Level

Accommodations in postsecondary settings have become commonplace for many students with learning disabilities (LD) who have documented needs. Many of the accommodations professionals recommend for students with LD are based on an analysis of the course demands, the student's functional limitations, and a basic understanding of how the accommodation can facilitate the demonstration or acquisition of knowledge. However, little is known about which accommodations are recommended for math, science, and foreign language courses as well as the effectiveness of those accommodations. Because these content areas pose substantial hurdles for secondary students with LD who may transition to postsecondary settings, a review of the literature was conducted to evaluate current practices in the provision of accommodations to postsecondary students with LD in math, science, and foreign language courses. Findings indicate strong empirical evidence for extended test time for algebra exams and emerging research in changes to foreign language instruction. Recommendations for further research are provided.     

Using Number Lines to Solve Math Word Problems: A Strategy for Students with Learning Disabilities

Students with learning disabilities (LD) consistently struggle with word problem solving in mathematics classes. This difficulty has made curricular, state, and national tests particularly stressful, as word problem solving has become a predominant feature of such student performance assessments. Research suggests that students with LD perform poorly on word problem‐solving items due primarily to deficits in problem representation. Therefore, it is imperative that teachers provide these students with supplemental problem‐solving instruction that specifically targets the development of representational strategies. This article describes how one representational strategy, using number lines, can be used to model word problems as part of a comprehensive problem‐solving intervention to improve the conceptual understanding of math word problems and, subsequently, the problem‐solving performance of students with LD.     

The Test‐Taking Strategy Intervention for College Students with Learning Disabilities

Limited research exists related to empirically validated strategies to assist college students with learning disabilities (LD). Given that students with LD demonstrate both fewer test‐taking skills and higher levels of test anxiety than their peers without LD, and poor test‐taking skills contribute to higher levels of test anxiety, such research is critical. The present study examines the effectiveness of the test‐taking strategy on test performance (timed/untimed), degree of strategy usage, and time on test‐taking task, with a sample of university students with LD. This strategy has been successful with adolescents with LD, but has not been studied with postsecondary populations. Results of a multiple baseline design suggested that the strategy was an effective intervention for these students. Implications are discussed.     

Technology Integration for Students with Disabilities: Empirically Based Recommendations for Faculty

In 3 empirical studies we examined the computer technology needs and concerns of close to 800 college and university students with various disabilities. Findings indicate that the overwhelming majority of these students used computers, but that almost half needed some type of adaptation to use computers effectively. Data provided by the students and by a small sample of professors underscore the importance of universal design in a variety of areas: courseware development, electronic teaching and learning materials, and campus information technology infrastructure. Sex and age of students were only minimally related to attitudes toward computers or their use in our samples. Key findings summarize the problems faced by students with different disabilities as well as the computer related adaptations that are seen as helpful. These are used to formulate concrete, practical recommendations for faculty to help them ensure full access to their courses.     

Cognitive Strategy Instruction for Mathematical Word Problem-solving of Students with Mathematics Disabilities in China

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.
