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…

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…

This study compared effects of two approaches to hands-on science, supported inquiry science (SIS) and activity-based science, in six urban and two suburban fourth-grade general education classrooms involving 172 students, 33 of whom had learning disabilities (LD). The study found that students with and without LD demonstrated greater concept…

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…

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 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. (Author/CL)

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)

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)

Shortcomings of mathematics curricula are described and research on the use of sameness analysis with learning-disabled and at-risk students is outlined. The paper then illustrates how to teach addition-subtraction and multiplication-division relationships and their interrelationships in the context of solving word problems in mathematics.…

This paper describes common practices in social studies instruction and proposes a conceptually based model of history instruction for learning-disabled students, involving sameness analysis and integrating concepts into a network of knowledge. The model includes preskill instruction, problem-solution-effect analysis and note taking, vocabulary…
