Can a school or district improve student achievement simply by switching to a higher quality textbook or curriculum? We conducted the first multi-textbook, multi-state effort to estimate textbook efficacy following widespread adoption of the Common Core State Standards (CCSS) and associated changes in the textbook market. Pooling textbook adoption…

A formative pilot study of a fractions intervention was conducted to address the intervention's potential for improving fifth-grade struggling students' knowledge of fractions, and to identify any logistical or instructional design issues, before scaling up for a randomized control trial. In the first section, we provide details of the formative…

The purpose of this study was to explore the efficacy of fractions intervention with and without an embedded self-regulation (SR) component for third-grade students at risk for mathematics disabilities. Fractions intervention focused on magnitude understanding and word problems. Embedded SR was designed to support a growth mindset (fostering…

We estimate relative achievement effects of the four most commonly adopted elementary mathematics textbooks in the fall of 2008 and fall of 2009 in California. Our findings indicate that one book, Houghton Mifflin's "California Math," is more effective than the other three, raising student achievement by 0.05 to 0.08 student-level…

The Common Core Mathematics Standards have raised expectations for schools and students in the United States. These standards demand much deeper content knowledge from teachers of mathematics and their students. Given the increasingly diverse student population in today's classrooms and shortage of qualified special education teachers,…

Research shows that some elementary math curricula are more effective than others at increasing student achievement. Most studies in this research base typically included teachers and classrooms that differ, so the results represent "average" curriculum effects, which raises an important question: Are curricula that are effective on…

This study examined the effects of an academic music intervention on conceptual understanding of music notation, fraction symbols, fraction size, and equivalency of third graders from a multicultural, mixed socio-economic public school setting. Students (N = 67) were assigned by class to their general education mathematics program or to receive…

We use data from one of the few states where information on curriculum adoptions is available--Indiana--to empirically evaluate differences in performance across three elementary-mathematics curricula. The three curricula that we evaluate were popular nationally during the time of our study, and two of the three remain popular today. We find large…

This brief is directed to researchers and adds to the research base about instructional practices that are related to student achievement. Additional evidence on these relationships can suggest specific hypotheses for the future study of such instructional practices, which, in turn, will provide research evidence that could inform professional…

This study compared mathematics achievement in Illinois elementary schools using the "Everyday Math" and "Saxon Math" curricula. The Illinois Standards Achievement Test (ISAT) was used as the measure of student achievement. Multiple correlation analyses showed that the type of curriculum used was a significant predictor of…

The purpose of this study was three-fold. First, the study determined the effects of mathematics teaching strategies on the performance of elementary students on a state-standardized test. More specifically, this study was concerned with the influence of the Everyday Math teaching strategies versus the Sharon Wells' teaching strategies on the…

This appendix provides the details that underlie the analyses reported in the evaluation brief, "After Two Years, Three Elementary Math Curricula Outperform a Fourth." The details are organized in six sections: Study Curricula and Design (Section A), Data Collection (Section B), Construction of the Analysis File (Section C), Curriculum…

This article examines the effectiveness of four elementary school math curricula: (a) "Investigations in Number, Data, and Space"; (b) "Math Expressions"; (c) "Saxon Math"; and (d) "Scott Foresman-Addison Wesley Mathematics" ("SFAW"). These curricula are distinct from one another and represent many…

Homework represents one research-based instructional strategy linked to student achievement. However, challenges abound with its current practice. This paper presents the results of three 2-year longitudinal interventions of the Teachers Involve Parents in Schoolwork (TIPS) homework program in elementary mathematics, middle school language arts,…

This nonexperimental, quantitative, cross-sectional, explanatory study (Johnson 2001, p. 10) investigated the differences between a reform-based elementary school mathematics program, traditional elementary school mathematics programs, and General Education student achievement in high-socioeconomic districts on the New Jersey Assessment of Skills…
