The pivotal role of Algebra in the educational trajectories of U.S. students continues to motivate controversial, high-profile policies focused on when students access the course, their classroom peers, and how the course is taught. This random-assignment partnership study examines an innovative district-level reform--the Algebra I…

Over the years, the nation's large urban school districts have consistently learned from the progress of their peer districts across the country. Great City School districts that have embraced the challenge of educating America's urban children have recognized the value of benchmarking their performance and growth against the progress of others.…

In this study, the authors highlight the differences in classroom-, teacher-, and school-level factors in 8th and 9th grade algebra experiences along socioeconomic and racial/ethnic lines using nationally representative survey data from the American Mathematics Educator Study. Several takeaways emerge from this analysis. The analysis shows that…

This Data Point uses data from the High School Longitudinal Study of 2009 (HSLS:09), a nationally representative, longitudinal study of more than 23,000 ninth-graders in 2009, to examine the association between the timing of Algebra I coursetaking and enrollment in postsecondary education. HSLS:09 cohort members were asked when they last took…

From 2016 to 2021, the Better Math Teaching Network (BMTN) aimed to transform high school mathematics teaching in New England. Researchers and teachers worked together to make high school Algebra I classes more student centered. The BMTN was piloted with a group of nine teachers during the 2015-2016 school year and added teachers the following…

Purpose: The purpose of the study was to evaluate the implementation and impact of the IDEA Public Schools' Mathematics Curriculum Redesign (MCR) effort, funded by an Innovation and Research (EIR) grant. Methods: The study used a quasi-experimental matching design to examine the effect of MCR on student achievement outcomes. The study compared…

This document provides the two appendixes that accompany the full report, "Algebra I and College Preparatory Diploma Outcomes among Virginia Students Who Completed Algebra I in Grades 7-9." Appendix A, "Methods," details the data sources, study population, and analysis methods used in the study. Appendix B, "Supporting…

On the Partnership for Assessment of Readiness for College and Careers (PARCC) assessments, the attainment of performance level 4 is intended to indicate college readiness or being "on track" to college and career readiness. Students who achieve Level 4 should have a 0.75 probability of attaining at least a C in entry-level,…

These are the appendixes for the report, "District Changes in Student Achievement and Local Practice under Georgia's District and School Flexibility Policy." Five appendixes are included in the document: (1) About the study; (2) Data and methods; (3) Supporting analysis; (4) Survey instrument; and (5) Interview protocol. [For the full…

This report provides a first look at selected findings from the first follow-up of the High School Longitudinal Study of 2009 (HSLS:09). HSLS:09 focuses on understanding students' trajectories from the beginning of high school into higher education and the workforce. The core research questions for the study explore secondary to postsecondary…

This study examined teacher perceptions of online and face-to-face professional development (PD) in four large school districts implementing an integrated school improvement initiative. The online PD component of this study was designed to support core 9th grade mathematics curriculum, and aligned safety net programs in literacy and mathematics.…

Unlike in elementary school, high-school teacher effects may be confounded with both selection to tracks and unobserved track-level treatments. I document sizable confounding track effects, and show that traditional tests for the existence of teacher effects are likely biased. After accounting for these biases, high-school algebra and English…

This First Look presents findings from the base-year survey of the newly launched High School Longitudinal Study of 2009 (HSLS:09), the first round of a study that will follow a ninth-grade cohort through high school and into their postsecondary years. HSLS:09 is the fifth in a series of National Center for Education Statistics (NCES) high school…

Understanding the meaning of rational numbers and how to perform mathematical operations with those numbers seems to be a perennial problem in the United States for both adults and children. Based on previous work, we hypothesized that giving students more time to practice using rational numbers in an environment that enticed them to apply their…

In 2006-07, seven Wake County Public School System (WCPSS) middle schools piloted Algebraic Thinking as an alternate approach to teaching middle school mathematics. Algebraic Thinking was developed to help students in grade 6 reach higher mathematics courses by combining the regular and advanced middle school mathematics courses into one…
