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…

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)

Results suggested that LD adolescents do not automatically generalize recently learned social skills to novel role playing situations and the natural environment. Also, high performance in a novel role playing situation does not necessarily mean that a student will show a correspondingly high performance in the natural environment. (Author/SEW)

A study involving four male beginning readers with learning disabilities compared the effects on gains in fluency of two types of mastery criteria. One required students to reread a passage until they demonstrated 3 successive improvements; the other required rereading until 90 correct words per minute were reached. Both were successful;…

This paper proposes for consideration by intervention researchers two instructional parameters that potentially can promote transfer of learned strategies in students with learning disabilities. The two parameters are mediating student mindfulness during strategy learning and at transfer and engaging in transfer-promoting instruction. (JDD)

Steps for enhancing skills and motivation for solving interpersonal problems are included. In addition, reference is made to planning intervention for learning disabled students. (Author/SEW)
