In this article, the authors consider the power and limitations of responsiveness-to-intervention (RTI) for reducing the need for ongoing and intensive services for the segment of the school population traditionally identified as having a learning disability in mathematics. To assess the robustness of RTI, the authors describe four studies with…

Teacher knowledge and instructional expertise have been found in correlational and pre- and post-test studies to be related to student reading achievement. This article summarizes data presented in this special issue and additional research to address four questions: (a) What do expert reading teachers know? (b) Why do teachers need to acquire…

This article advocates an approach to supporting students who experience difficulties in learning, irrespective of nosology, particularly in the key areas of literacy and numeracy. In the state of Queensland, Australia, a distinction has been made between students' experiencing learning difficulties and those who have learning disabilities (LD).…

A conceptual overview of the Regression Discrepancy Model (RDM) for assessing discrepancy between intelligence quotient and achievement scores is offered. Six RDM goals are identified, and figures from a RDM computer output show basic outcomes. Strengths and weaknesses of the RDM are discussed, without the use of complex mathematical descriptions.…

Five components were identified as crucial to the success of the mainstreamed peer tutoring program (selection, training, matching, supervision, and communication with/support for the regular classroom teacher). Data provided support for the conclusion that the on task behavior of tutees improved significantly as a result of the program. (SB)

The possibility that four famous men--Thomas Alva Edison, Woodrow Wilson, Hans Christian Andersen, and Leonardo da Vinci--might have been reading disabled is considered by examining information concerning: (1) biographical records, (2) cognitive characteristics, (3) neuropsychological characteristics, and (4) biological characteristics. (Author/DB)

Adolescents (n=18) with learning disabilities or low achievement were trained to use interactive dialogs to collaboratively plan and revise individually written opinion essays. Analysis indicated that, when compared with untrained controls, trainees improved significantly from pretest to posttest in clarity and cogency of their writing and…

The article explores information processing models of spelling performance and argues that an adequate theory of spelling processes must include: (1) qualitative changes in performance as a function of maturation that underlie development of automaticity; (2) transactional development of spelling-related knowledge structures and efficient…

An overview is presented of information processing analyses of knowledge and performance in three areas of the elementary mathematics curriculum: basic addition and subtraction facts, complex procedures such as multicolumn subtraction, and the solution of word problems. Theories of the knowledge associated with "expert" performance are discussed.…
