Virtual manipulatives are interactive and dynamic visual objects on a screen, which allow students to manipulate them to construct mathematical knowledge. The purpose of this study was to synthesize the literature on interventions that used virtual manipulatives to improve the mathematics performance of K-12 students with learning disabilities. A…

This meta-analysis synthesized the findings of experimental and quasi-experimental studies to determine the efficacy of math interventions for enhancing the word problem-solving accuracy of students with mathematics difficulties in Grades 4 to 12. Further, we identified intervention and design characteristics that moderate the effectiveness of…

Meta-analysis is one approach for synthesizing research studies to identify generally effective instructional practices for students with learning disabilities (LD). In this article, we define core components of meta-analytic literature reviews, discuss how to interpret findings from meta-analyses, and provide guidelines for how research consumers…

This study aimed to evaluate the effects of intervention using graphic organizers on the cognitive and affective improvement of students with intellectual disability (ID), with learning disability (LD), without disability, and at-risk learners in Korea. A total of 49 peer-reviewed journals and dissertations for the last 20 years were included for…

The purpose of the systematic review of mathematics intervention syntheses was to identify patterns and gaps in content areas, instructional strategies, effect sizes, and definitions of learning disabilities (LD), mathematics LD (MLD), and mathematics difficulty (MD). Using rigorous inclusion criteria, we evaluated 36 syntheses that included 836…

The purpose of this systematic review was to examine the effectiveness of proportional reasoning interventions for students with learning disabilities (LD) or mathematics difficulty (MD). We evaluated fifth to ninth grade interventions on proportional reasoning content, instructional features, and disability and difficulty identification. The nine…

This study employed a meta-analytic approach to examine the effectiveness of graphic organizers (GOs) in improving academic and behavioral outcomes for K-12 students with disabilities, drawing from the single-case special education literature. Moderators at participant and study level were analyzed in addition to the main effects. A comprehensive…

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…

This systematic review article summarizes the effects of explicit text structure instruction on expository text comprehension for adolescents with learning disabilities or at risk for reading failure. A thorough literature search with four databases and backward citation search identified nine studies published in the past 22 years for inclusion…

Algebra problem solving is one of the most difficult areas in the mathematics curriculum for secondary students with learning disabilities (LD) due to the higher-order reasoning demands and strategic thinking required. The purpose of this review is to examine how effective algebra problem-solving interventions conceptualize the cognitive processes…

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…

This paper provides a current and thorough review of the literature on the use of video modeling for students with learning disabilities published over the last four and a half decades. Eight video modeling intervention studies were retrieved and grouped into four areas: (a) mathematics, (b) reading, (c) social studies, and (d) social behavior.…

Opportunities for students to learn mathematics through innovative, authentic experiences in an inquiry-based instructional approach have become much more common for students in regular and advanced math classes. Yet, the same cannot be said for students with learning disabilities. One of the primary reasons is that key tenets of the inquiry…

We conducted a comprehensive synthesis of computer-assisted instruction (CAI) research that aimed to facilitate the learning of mathematical word problem solving involving elementary and secondary school students with learning disabilities or difficulties in mathematics. We examined a total of 13 studies under the four instructional categories:…

Writing in science can be challenging for all learners, and it is especially so for students with cognitive or language-based learning difficulties. Yet, we know very little about how to support students with learning disabilities (LD) or who are English learners (EL) when asked to write for authentic purposes during science instruction.…
