The efficacy of a research-based fraction sense intervention for sixth graders with or at risk for mathematics difficulties (N = 52) was examined. The intervention aimed to build understanding of fraction magnitudes on the number line. Key concepts were taught with a narrow range of denominators to develop deep understanding. The intervention was…

This study compared how students with learning difficulties in math (MLD) who were randomly assigned to two instructional conditions answered items on problem solving tests aligned to the Common Core State Standards Initiative for Mathematics. Posttest scores showed improvement in the math performance of students receiving Enhanced Anchored…

This study examined the effect of schema-based instruction (SBI) on the proportional problem-solving performance of students with mathematics difficulties only (MD) and students with mathematics and reading difficulties (MDRD). Specifically, we examined the responsiveness of 260 seventh grade students identified as MD or MDRD to a 6-week treatment…

The purpose of this study was to assess the relative contribution of teacher and tutor ratings of inattentive behavior in two different instructional settings in predicting students' performance on fraction concepts and whole-number calculations. Classroom teachers rated each student's attentive behavior in a whole-class setting and tutors rated…

This publication provides a comprehensive interpretation of the second mathematics assessment completed during the 1977-78 school year by the National Assessment of Educational Progress (NAEP). The NAEP results suggest strong implications for the mathematics curriculum of the 1980's that mathematics educators need to evaluate with care. The…

Poor, minority, and low ability students suffer most from the general lack of sustained opportunity to study mathematics in American public schools. Studies indicate that preschool and kindergarten students show only minor social class or racial differences in mathematical thinking and that differences in mathematical performance among older…
