The purpose of this article is to offer teacher training and professional development recommendations in mathematics based on the findings of a federally funded 3-year intervention study that improved the problem solving of middle school students with a focus on students with learning disabilities. Over the 3-year project, 29 seventh and eighth…

This article presents a meta-analysis of experimental and quasi-experimental studies in which intermediate and secondary students with learning disabilities were taught science content through the use of graphic organizers (GOs). Following an exhaustive search for studies meeting specified selection criteria, 23 standardized mean effect sizes were…

An overview of research topics and findings from an interdisciplinary, programmatic line of research on writing over the past 25 years is presented. The cross-sectional assessment studies (grades 1 to 9) showed which measures uniquely explained variance in handwriting, spelling, and composing and thus validated their use in assessment. These and…

This study investigated the effectiveness of a multicomponent reading intervention implemented with middle school students with severe reading difficulties, all of whom had received remedial and/or special education for several years with minimal response to intervention. Participants were 38 students in grades 6-8 who had severe deficits in word…

Classroom communication figures prominently in current math reform efforts. In this study, we analyze how one teacher used writing to support communication in a seventh-grade, low-track mathematics class. For one school year, we studied four low-achieving students in the class. Students wrote in journals on a weekly basis. Using classroom…

This study was part of a larger research program designed to investigate how effort interacts with strategy use to mediate the academic performance of successful students with learning disabilities (LD) and how teachers' and students' perceptions influence these relationships. The sample consisted of 46 students with LD and 46 matched students…

This study investigated changes in teachers' and students' perceptions of students' effort, strategy use, and academic difficulties when strategy instruction was infused into the classroom curriculum. The sample consisted of 201 students with learning disabilities, 210 average achievers, and 57 teachers from Grades 4-9 in two urban and suburban…
