In this commentary, I examine some of the distinctive, foundational difficulties in learning fractions and other types of rational numbers encountered by students with a mathematical learning disability and how these differ from the struggles experienced by students classified as low achieving in math. I discuss evidence indicating that students…

Errors in written multi-digit computation were investigated in children with math difficulties. Third- and fourth-grade children (n = 291) with coexisting math and reading difficulties, math difficulties, reading difficulties, or no learning difficulties were compared. A second analysis compared those with severe math learning difficulties, low…

The present study explored the double-deficit hypothesis (DDH) in a sample of 146 college students with and without reading disabilities (RD). The results indicated that although both phonological awareness (PA) and visual naming speed (VNS) contributed to performance on measures of decoding and comprehension, their relative contribution was…

This study examined the relations between reading-related cognitive skills and word reading development of Chinese children with dyslexia in their Chinese language (L1) and in English (L2). A total of 84 bilingual children--28 with dyslexia, 28 chronological age (CA) controls, and 28 reading-level (RL) controls--participated and were administered…

This study examined achievement, neuropsychological, and intervention outcomes at a mean age of 11 years in children with very low birthweight (VLBW, < 1,500 g) compared with a term-born control group. To assess the prevalence and correlates of specific learning disabilities (LD), the sample was limited to children without neurosensory disorders…

The teaching of mathematics in Australian schools has received considerable attention over the past decade. States and territories have designed and implemented new mathematics syllabi, and education sectors have supported teachers through sustained professional learning initiatives. Whereas the major focus of these initiatives has been on…

"QuickSmart" is a basic academic skills intervention designed for persistently low-achieving students in the middle years of schooling that aims to improve the automaticity of basic skills to improve higher-order processes, such as problem solving and comprehension, as measured on standardized tests. The "QuickSmart" instructional program consists…

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…

Issues and needs identified in a 1984 survey of professionals in the field of learning disabilities are summarized and grouped as follows: (1) theory and research; (2) practice and related applied research (subtyping, differential programming, intervention focus, efficacy, and prevention/early intervention); (3) training (including categorical…

A group of seventh- and eighth-grade Italian students with low achievement (LA) in learning English as a foreign language (FL) was selected and compared to a group with high achievement (HA) in FL learning. The two groups were matched for age and nonverbal intelligence. Two experiments were conducted to examine the participants' verbal and…
