Single-case research design is a useful methodology for evaluating the presence of a functional relation between an intervention and the mathematical performance of students with a learning disability. However, a functional relation cannot be established with threats to internal validity of the design. External validity is impacted if researchers…

Students with exceptionalities who do not make adequate progress with core instruction in mathematics require more intensive research-based interventions such as explicit instruction or video modeling to address instructional needs. This study examined the effects of combining point-of-view video modeling, explicit instruction, and augmented…

This meta-analysis examined the ecological and population validity of intervention research for students with low mathematics achievement (SWLMA). Forty-four studies published between 2005 and 2019 that met the inclusionary criterion were included in this analysis. Our findings suggest, to improve the external validity and generalizability of…

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…

This study used a multiple probe across participants design, replicated across two interventions and counterbalanced across participant groups to examine the effects of number sense intervention and extensive practice intervention on strategy transformation when students with mathematics learning disabilities (MLD) solved basic fact problems. In…

Secondary students with a learning disability in mathematics often struggle with the academic demands presented in advanced mathematics courses, such as algebra and geometry. With greater emphasis placed on problem solving and higher level thinking skills in these subject areas, students with a learning disability in mathematics often fail to keep…

This study assessed the efficacy of experimental analysis for determining a best intervention program for improving oral reading fluency for students with learning disabilities. Following a two-session baseline condition, four treatments to increase reading fluency (repeated reading, listening passage preview, repeated reading with easier…

The effectiveness of two techniques to help nine elementary learning disabled students generalize a computation skill was investigated. Results showed that demonstration and modeling plus feedback was sufficient to increase some Ss' ability, but that others require further intervention. (Author/CL)

Using a learning strategies approach, the article outlines specific procedures to promote acquisition and generalization of learning strategies in LD adolescents. First, students are taught a specific strategy in isolation before being asked to apply it to controlled materials and later, to transfer the strategy to regular class content. (Author)

A survey of 66 experts in learning disabilities (LD) found treatment maintenance, generalization, and assessment and remediation of academic problems ranked highest as research priorities. Analysis of two leading LD journals found current topics to include academic assessment and remediation, while ignoring generalization and maintenance of…

The study investigated whether 25 intermediate grade learning disabled students would generalize creativity training to increased competence on a spontaneous writing task. Following creativity training, including such activities as nonjudgmental brainstorming, the experimental group's writing significantly improved in number of thought units,…

The "count-by" technique of multiplication was taught to a fourth grade student with learning disabilities. The student learned to count by numbers not typically taught (e.g., fours, sevens, and eights). The method resulted in substantial increases in correct multiplications performed per minute, which were maintained and generalized to…

A demonstration-plus-feedback technique was applied in an attempt to reduce the systematic inversion errors in subtraction in nine learning disabled students (ages 9-11 years). Journal availability: see EC 112 927. (DLS)

Preskills and strategy training were shown to be effective in helping four eight- to nine-year-old learning disabled children acquire basic multiplication and division skills. (Author)

A metacognition model that can help understand general problem-solving deficits in learning disabled students is presented. Two components of metacognition are highlighted: executive processes and attributional beliefs. An educational package combining these components with specific strategy training is illustrated as an approach to improving…
