The primary goal of the present systematic review was to examine the criteria and measures used for assessing students with "specific comprehension deficit" (SCD) who have adequate decoding skills but still perform poorly on reading comprehension assessments. From a systematic review of 32 studies, we found four predominant selection…

This research synthesizes studies that used a Digitalized Interactive Component (DIC) to assess K-12 student mathematics performance during Computer-based-Assessments (CBAs) in mathematics. A systematic search identified ten studies that categorized existing DICs according to the tools that provided language assistance to students and tools that…

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…

Students with specific poor comprehension (SPC) can sound out words accurately, but have difficulty understanding what they read. However, most existing reading intervention studies on students with reading disabilities did not differentiate students with SPC from other types of students with reading disabilities who accompany with decoding…

An overview of the literature on developmental dyslexia is offered, and two approaches to the subtyping problem are illustrated and briefly discussed. Potential implications of some aspects of the interactive reading theories for the study of reading dysfunction are explored. (Author/CL)

The historical background of alexia (loss or impairment of the ability to comprehend written or printed language based on damage to the brain) is reviewed, classification and symptomatology considered, theories on the involvement of right hemisphere reading are noted, and the neural basis of reading is postulated. (CL)

Calls into question the validity and usefulness of classifying poor readers into learning disability and nonlearning disability categories on the basis of the discrepancy between their IQs and reading achievement scores. A review of the research indicates that the premises on which this classification rests are not valid. (SLD)

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)

This paper discusses studies of visual dyslexia, the nature of visual processes involved in word recognition, and the contribution of visual memory to word recognition. The paper concludes that, though defects in the physiological aspects of visual processing can lead to reading difficulties, evidence does not indicate the existence of visual…

This article discusses research on the traditional use of the IQ-achievement discrepancy to define specific reading disability. It highlights results from a study which found that IQ scores did not differentiate between poor readers who were found to be readily remediated and poor readers who were difficult to remediate. (Contains references.)…

Specific reading disability/dyslexia is examined as the one type of learning disability for which research results are consistent enough to suggest a model. The implications of this model are considered and three types of learning disabilities are discussed: specific language impairments, specific reading disability/dyslexia, and specific math…

It is suggested that reading is not a unitary process, but the acquisition of a succession of skills. Different retarded readers may break down at different stages in the acquisition of these. Each disability type may be associated with a particular type of deficiency in conceptual thinking. (Author/SJL)

This article first describes two types of assessment (problem solving and standard treatment protocol) within a "responsiveness-to-instruction" framework to identify learning disabilities. It then specifies two necessary components (measures and classification criteria) to assess responsiveness-to-instruction, and present pertinent findings from…

This paper discusses distinguishing learning disabilities and attention deficit hyperactivity disorder (ADHD) from each other and from other problems of childhood; a new conceptual model and working definition for reading disability; distinction between the psychological construct of "attention" and ADHD, the disorder; and the need for a…

Poor readers often know only the most common meanings or nuances of multimeaning (polysemic) words frequently encountered in reading materials. Teacher-directed, systematic vocabulary instruction must focus on specific problem areas. A three-step plan for teaching multimeaning words is proposed, emphasizing recognition and classification of word…
