Word problem-solving (WPS) poses a significant challenge for many students, particularly those with mathematics difficulties (MD), hindering their overall mathematical development. To improve WPS proficiency, providing individualized and intensive interventions is critical. This umbrella review examined 11 medium- to high-quality meta-analyses to…

In this synthesis, we reviewed 65 studies involving elementary students (i.e., grades 1-5) identified with mathematics difficulty (MD) in which authors implemented a mathematics intervention. Of these studies, we identified 33 group designs, 9 quasi-experimental designs, and 23 single-case designs. We aimed to synthesize performance differences…

The paper reviews the recent research bearing on the single cause/multiple cause controversy in regard to reading disabilities. The inadequacy of the common practice of comparing a group of disabled readers with a control group is noted. (Author/SW)

Recently, talk of a new type of learning disability (LD)--a foreign language learning disability, or FLLD--has made its way into the LD and foreign language (FL) literature. However, no empirical evidence has been published to support the concept of a "disability" for FL learning by those professionals who use the term. In this article, the author…

A study of 22 learning disabled (LD) and normal children (mean age nine years) was undertaken to illustrate the research problems involved in using analysis of covariance to control for differences between LD and normal children on measures of intelligence. (SW)

Researchers have hypothesized four levels of instructional dialogue and claimed that teachers can improve children's language development by incorporating these dialogue levels in their classrooms. It has also been hypothesized that enhancing children's early language development enhances children's later reading development. This…

A review of 208 studies of children with learning disabilities (LD) published in 10 major journals between 1988 and 1990 examined the extent to which recommendations concerning research design and reporting made in 1980 and 1984 have been implemented. The review found continuing problems, including imprecise subject descriptions, heterogeneous…
