The acquisition of numerical competency is regarded as imperative for quality of life and economic well-being. Many children have significant mathematical learning difficulties known as dyscalculia. The aim of this research was to systematically review the available literature for interventions with children presenting with dyscalculia in primary…

Requirements for reasoning, explaining, and generalizing mathematical concepts increase as students advance through the educational system; hence, improving overall mathematical proficiency is critical. Mathematical proficiency requires students to interpret quantities and their corresponding relationships during problem-solving tasks as well as…

The primary goal of this review is to highlight current research and theories describing the neurobiological basis of math (MD), reading (RD), and comorbid math and reading disability (MD+RD). We first describe the unique brain and cognitive processes involved in acquisition of math and reading skills, emphasizing similarities and differences in…

Through a review of the literature on mathematical learning disabilities (MLD) and low achievement in mathematics (LA) we have proposed a model classifying mathematical skills involved in learning mathematics into four domains (Core number, Memory, Reasoning, and Visual-spatial). In this paper we present a new experimental computer-based battery…

Two years of language study is a requirement in most colleges and universities for many degree programs and, at the high school level, an expectation for college-bound students. However, some very capable students with specific learning disabilities (SLD) have difficulty learning a second language. Recent research has identified characteristics of…

Discusses cognitive, affective, and linguistic influences on foreign language learning. It proposes the Linguistic Coding Differences Hypothesis (LCDH) model for understanding foreign language learning problems. The empirical support for the LCDH model is reviewed. Diagnostic, pedagogical, and policy implications are addressed. (Author/DB)

The article reviews the literature on the quantification of achievement-aptitude differences in learning disabled students, outlines and discusses criteria for new and more adequate procedures, and presents step-by-step procedures that can be routinely followed. (Author/DLS)

A critical review of the literature dealing with quantification of achievement-aptitude differences for identifying learning disabled (LD) readers revealed that methods developed to date suffer from grave inadequacies. Among the methods considered were those of the following individuals: G. Bond and M. Tinker, M. Monroe, A. Harris and E. Sipay, H.…

Specific aptitude clusters from the Woodcock-Johnson Psycho-Educational Battery (WJPEB) are examined to determine their effectiveness in evaluating aptitude-achievement discrepancies. Advantages of the Scholastic Aptitude clusters over the Broad Cognitive Ability clusters are outlined. Major types of discrepancies, rationale, and research on the…

Examines WAIS-R profiles of 194 college students diagnosed with learning disabilities (LD) to assess where they yield unique and interpretable profiles. Results show nearly 94% match profiles found in the WASI-R standardization sample. Also, shapes fail to explain a significant proportion of variation in student academic skills. (Author/JDM)

This review of research finds that, when IQ and reading ability are controlled, "true" math deficits of students with learning disabilities, attention deficit disorders, and attention deficit hyperactive disorders (ADHD) are specific to mathematical concepts and problem types. Slow computation affects problem solving by increasing attentional…

In this interview, two collaborators in research on teaching foreign languages to learning-disabled students are questioned regarding specific foreign language learning disabilities, possible subtypes, diagnosis, policies of colleges regarding students unable to meet foreign language requirements, and recent research in the field.

The article provides an overview of a special topical issue on information processing as it relates to learning disabilities. Components of information processing theory are described, a model of information processing is presented, and subsequent articles in the special issue are summarized. (JW)

The importance of neuropsychological paradigms of higher order human information processing in providing remedial services to learning-problem children and in providing a guide to the habilitation of learning for all children is explained. The conceptual requirements of such models as well as their implementation are described. (Author/AL)

The article examines the relationship between biological defects and educational aptitude and achievement. (Author/PHR)
