Conceptual replications are part and parcel of education science. Methodologically rigorous conceptual replication studies permit researchers to test and strengthen the generalizability of a study's initial findings. The current conceptual replication sought to replicate the efficacy of a small-group, first-grade mathematics intervention with 240…

The purpose of this study was to determine the effectiveness of a systematic, explicit, intensive Tier 3 (tertiary) intervention on the mathematics performance of students in second grade with severe mathematics difficulties. A multiple-baseline design across groups of participants showed improved mathematics performance on number and operations…

In this article, the authors summarize results from 5 randomized controlled trials assessing the effects of intervention to improve the fraction performance of fourth-grade students at risk for difficulty in learning about fractions. The authors begin by explaining the importance of competence with fractions and why an instructional focus on…

As empirical studies have consistently shown, low achievement in mathematics at the secondary level can often be traced to deficits in the understanding of certain basic arithmetic concepts taught in primary school. The present intervention study in middle schools evaluated whether such learning deficits can be reduced effectively and whether the…

The purpose of this study was to examine the cognitive and academic profiles associated with learning disability (LD) in reading comprehension, word reading, applied problems, and calculations. The goal was to assess the specificity hypothesis, in which unexpected underachievement associated with LD is represented in terms of distinctive patterns…

The LD first graders were found to have a lower level as well as greater variability in their understanding of basic concepts. The greatest discrepancy of the LD group was found on concepts of quantity, space, and miscellaneous, respectively. (Author)

To focus on the importance of concept development and metacognitive processes to the act of writing, curricular changes must be made, including shifting the emphasis from mechanics to content and meaning. Six suggestions are offered for improving the quality and quantity of the written product of learning disabled students. (CL)

The paper reviews research which presents evidence that learning disabled (LD) children, like other groups that show performance deficiencies, do not spontaneously employ appropriate goal directed task strategies in many situations. (Author/PHR)

A longitudinal investigation on development of conservation skills in 31 learning disabled (LD) children suggested that delayed transition between preoperational and concrete operational thought may be an important factor in understanding the continued school failure of learning disabled children.

Male and female retarded readers (N=80) at two age levels (6.5 to 8.5 years and 10.5 to 12.5 years) did not differ significantly on a number of perceptual, visual-motor, linguistic, and concept formation abilities. (Author)

This article introduces a series of papers that explain and illustrate how a higher order thinking curriculum can be designed for a full spectrum of students, including students with learning disabilities. The article discusses an approach in which concepts, rules, and strategies are taught by organizing content around the process of noting…

Three curricular approaches to spelling instruction are discussed: whole word; phonemic; and morphemic. Sameness analysis is used to indicate the theoretical potential of each approach for helping students with learning disabilities to achieve generalization in their spelling, and the influence of generalization upon retention and transfer is…

Discussed is the spatial concept model of J. Piaget in terms of the child's development from topological spatial relationships to Euclidean and projective relationships with implications for assessment and remediation of perceptual dysfunction. (DB)

Twenty-five studies were reviewed which reported scores of 883 disabled readers, 7 to 18 years of age on subtests of the Wechsler Intelligence Scale for Children. (Author/MC)

The study involving 54 children (10 to 15 years old) was concerned with identification of conceptual functioning as an avenue of differentiating between auditory processing problems and primary ego development difficulties within the context of appropriate instructional/remediation strategies.
