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…

This study examined the quality of the research base related to strategy instruction priming the underlying mathematical problem structure for students with learning disabilities and those at risk for mathematics difficulties. We evaluated the quality of methodological rigor of 18 group research studies using the criteria proposed by Gersten et…

Reading achievement scores for adolescents with disabilities are markedly lower than the scores of adolescents without disabilities. For example, 62% of students with disabilities read "below" the basic level on the NAEP Reading assessment, compared to 19% of their nondisabled peers. This achievement gap has been a continuing challenge…

This quasi-experimental study examined effects of a 12-week, teacher-delivered, morphologically focused intervention on writing outcomes for fifth-grade U.S. students. In order to help students gain control over the morphologically complex words that typify academic writing, the intervention called students' attention to the morphological…

The authors conducted a synthesis of studies of reading comprehension interventions for middle school students (Grades 6-8) identified with a learning disability. They identified 12 studies between 1979 and 2009 with treatment and comparison designs and 2 single-participant studies. Findings from the studies indicate large effect sizes for…

The teaching of mathematics in Australian schools has received considerable attention over the past decade. States and territories have designed and implemented new mathematics syllabi, and education sectors have supported teachers through sustained professional learning initiatives. Whereas the major focus of these initiatives has been on…

The poor achievement of secondary students with learning disabilities in mathematics is often affected by prior low achievement, low expectations for success, and inadequate instruction. Good instruction involves careful selection of examples; explicit instructional design; a parsimonious use of time and resources; and techniques such as direct…

Describes and illustrates five areas of instructional design in mathematics well suited to students with learning disabilities. Suggested learning strategies for teachers to incorporate include using big ideas and conspicuous strategies; teaching efficient use of time; giving clear, explicit instruction on strategies; and taking time for…

This article reflects on others serialized in the same publication and the general call for a scientific pedagogy in curriculum development around the field of learning disabilities. Curriculum design, textbook adoption processes, and ongoing curriculum alignment are discussed in terms of scientific pedagogy in general and sameness analysis in…

This study compared using explicit rule-based instruction and a basal-reader activity-based approach for teaching 40 fourth-grade students with learning disabilities to determine character motive in three types of narrative texts. Rule-based instruction was superior to the activity-based approach when teaching character motives irrespective of…

This article summarizes single-subject design intervention studies that include students with learning disabilities. Effect sizes of 85 studies were analyzed across instructional domains, sample characteristics, intervention parameters, and methodological procedures. Findings are supportive of the pervasive influence of cognitive strategy and…

This article presents research-based examples of effective instructional approaches for improving the quality of stories and essays written by students with learning disabilities. A common goal of the studies examined was to teach students how to organize writing tasks, generate ideas about the writing topics, and produce final written products…

This article explains reasons for focusing on social studies as an untapped domain in which to foster thinking and problem solving skills of students with disabilities, discusses the use of multimedia technology in supporting projects in the social studies, explores considerations in implementing multimedia design projects, and examines challenges…

Discusses the use of cognitive strategy instruction to improve students' performance in mathematics. The theoretical and research base for strategy instruction is reviewed, and developmental characteristics of students who have difficulties in mathematics are examined. A practical example of cognitive strategy instruction illustrates assessment…
