This study evaluated whether schema-based instruction (SBI), a promising method for teaching students to represent and solve mathematical word problems, impacted the learning of percent word problems. Of particular interest was the extent that SBI improved high- and low-achieving students' learning and to a lesser degree on the indirect effect of…

The purpose of the present review was to evaluate the quality of the research and evidence base for representation of problems as a strategy to enhance the mathematical performance of students with learning disabilities and those at risk for mathematics difficulties. The authors evaluated 25 experimental and quasiexperimental studies according to…

This study compared number sense instruction in three first-grade traditional mathematics textbooks and one reform-based textbook ("Everyday Mathematics" [EM]). Textbooks were evaluated with regard to their adherence to principles of effective instruction (e.g., big ideas, conspicuous instruction). The results indicated that traditional textbooks…

The purpose of this follow-up study was to evaluate the effectiveness of two consultation-based models to enhance the educational functioning of children with attention deficit hyperactivity disorder (ADHD) after 1 year of no treatment. Children (N = 167) meeting "Diagnostic Statistical Manual" (4th ed., text revision; 2000) criteria for attention…

A within-subject pretest-posttest comparison design was used to explore the effectiveness of a planning and writing intervention in improving the argumentative writing performance of five fourth-grade students with learning disabilities. Students were taught to collaboratively plan and revise their essays and independently write their essays using…

The purpose of this study was to examine the tenability of a curriculum-based mathematical word problem-solving (WPS) measure as a progress-monitoring tool to index students' rate of growth or slope of achievement over time. Participants consisted of 58 third-grade students, who were assessed repeatedly over 16 school weeks. Students were measured…

The purpose of this study was to evaluate the effectiveness of supplemental reading instruction on the reading performance of four (two boys, two girls) second graders who were English learners (ELs) and poor readers through the use of a multiple probe across-participants design. All students received instruction from a commercial reading program,…

Concept-teaching procedures in five basal language programs for kindergarten were analyzed on the basis of 11 design-of-instruction criteria. Concepts such as position, color, shape, size, and directionality were examined. Results suggest that the programs' concept-teaching procedures failed to adhere to essential principles for designing…

The present study evaluated the effectiveness of an instructional intervention (schema-based instruction, SBI) that was designed to meet the diverse needs of middle school students by addressing the research literatures from both special education and mathematics education. Specifically, SBI emphasizes the role of the mathematical structure of…

This study evaluated the validity of curriculum-based word problem-solving measures as indicators of proficiency in mathematics with a sample of 77 children in third grade. In the winter and spring of third grade, children completed a battery of general achievement tests in mathematics in addition to curriculum-based problem-solving and…

We previously conducted a curriculum analysis of third-grade mathematics textbooks aimed at investigating the extent to which teaching the recommended methods for problem solving adhered to the 2000 National Council of Teachers of Mathematics (NCTM) Standards and instructional design criteria. In this article, we extend the previous findings by…

The present study examines the effects of computer-assisted instruction (CAI) on the mathematics performance and classroom behavior of three second-through fourth-grade students with ADHD. A controlled case study is used to evaluate the effects of the computer software on participants' mathematics performance and on-task behavior. Participants'…

Four middle school students with learning disabilities and low mathematics performance received schema strategy training in problem schemata (conceptual understanding) and problem solution (procedural understanding). Results indicated that the schema-based strategy was effective in substantially increasing the number of correctly solved word…

This meta-analysis examines the effectiveness of functional mathematics instruction, specifically purchasing skill instruction, for individuals with disabilities. Twenty-eight intervention studies were identified and reviewed. Because all studies employed single-subject research designs, a nonparametric procedure, the percentage of nonoverlapping…

Few studies have comprehensively examined possible gender differences in the school functioning of children with attention deficit hyperactivity disorder (ADHD). This study investigated differences in academic, social, and emotional and behavioral functioning between 133 male and 42 female elementary school students who met research diagnostic…
