Geometry education is an important aspect of science, technology, engineering, and mathematics (STEM) education, but it is often overlooked in K-12 education in the United States. Chunking strategy reduces the cognitive load demanded in the processing of information, and it has been applied as a testing accommodation for high school students with…

Multifactorial models of dyslexia have expanded how we consider heterogeneity within the population of children with dyslexia. These models are predicated on the idea that cognitive/linguistic risk factors are not deterministic but instead probabilistic, with the likelihood of difficulties involving an interaction between risk and protective…

The purpose of this study was to examine the efficacy of a graphic organizer for improving the expository text comprehension of adolescent Spanish-English bilingual students with learning disabilities. Students were two females and one male. Using a multiple baseline single case design, researchers taught students to create a funnel map graphic…

One of the most persistent areas of difficulty in mathematics for children with learning disabilities (LDs) and difficulties is fractions. We report the development and initial testing of an intervention designed to increase access to and advancement in conceptual understanding. Our asset-based theory of change--a tested and confirmed learning…

The purpose of this single case design study was to examine the efficacy of using double-bubble Thinking Maps to improve the reading comprehension of middle school Spanish-English bilingual middle school students with learning disabilities. Participants included three female Spanish-English bilingual middle school students with learning…

The purpose of this study was to examine geometry interventions for students with learning disabilities. We synthesized nine intervention studies by focusing on the geometry concepts and skills taught to students with learning disabilities, intervention types used, instructional components embedded, and the methodological rigor of the studies.…

Impacts of rational number interventions among U.S. students in Grades 3 through 9 with mathematics difficulties are examined using a systematic review and meta-analysis. The primary goal of the meta-analysis was to identify instructional practices that are key drivers of student impacts. From approximately 1,200 published and unpublished study…

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 pilot study examined the promise of a Tier 2 Grade 6 intervention program for students at risk for difficulties in mathematics. The study utilized a quasi-experimental design. The final sample included 112 students in treatment (Promoting Algebra Readiness) and 86 students in control (standard district practice) conditions. The Promoting…

Previous studies of K-12 dyslexia legislation have described broad trends in legislative content, such as the presence or absence of screening and intervention requirements. This study uses document analysis to provide a finer-grained description of the laws to highlight critical variation in policy that will directly affect (a) the number and…

Few studies have considered academic vocabulary interventions for students who have learning disabilities (LD) and also are English learners (EL). This research explored the effects of the third year of the Creating Habits that Accelerate Academic Language of Students (CHAAOS) vocabulary intervention for eighth-grade students who received English…

The purpose of this review is to determine the evidence base classification of schema-based instruction (SBI) as an intervention to improve word problem-solving outcomes in mathematics for students with learning or mathematics disabilities in Grades K-12. Using the Council for Exceptional Children's quality indicators (QIs) and standards, we…

Interventions for individuals with or at risk for reading disability (RD) need not occur only during the typical school day. Educators and researchers have been actively seeking opportunities to extend literacy learning through home-based, summer, and other tutoring programs. Nevertheless, alternative settings can pose greater difficulty with…

English learners (ELs) with reading disabilities (RDs) have been among the lowest performers on academic achievement tests that assess vocabulary. To meet academic demands and prepare for college or careers, ELs with RDs clearly need support in terms of vocabulary acquisition; however, relevant research is scarce. This study investigated the…

The purpose of this feasibility study was to inform the development of an intervention to support reading and self-regulation for students with significant reading difficulties and disabilities (RDs), including dyslexia. Participants were 21 special educators, dyslexia specialists, and reading interventionists and 48 students in Grades 2 to 4.…
