The COVID-19 pandemic has affected student learning; according to the National Assessment of Educational Progress (2022), scores for students in the United States have shown a decline in mathematics. . One way educators can strengthen students' current mathematical knowledge and bridge to new content is through Number Talks. Number Talks are brief…

We used the Stanford education data archive (SEDA) data to examine the heterogeneity among urban school districts in the United States. The SEDA 2.1 includes data sets on students' mathematics (Math) and English language arts (ELA) achievement from 2008 to 2014 at the district level. Growth mixture modeling was used to uncover the underlying…

The development of math reasoning and 3-d mental rotation skills are intertwined. However, it is currently not understood how these cognitive processes develop and interact longitudinally at the within-person level -- either within or across genders. In this study, 553 students (52% girls) were assessed from fifth to seventh grades on 3-d mental…

Over the past 30 years, numerous policies have focused on closing the achievement gap in the United States. Despite this emphasis on mastery and proficiency, students continue to perform below expectations. We use standardized math test performance to explore whether schools have been able to eliminate the achievement gap across middle-level…

Ethnoracial inequality in educational achievement and attainment is a long-standing feature of the American education system. For example, national reading assessments show that White fourth graders scored nearly a standard deviation higher than Black or Hispanic students on average in 2015 (NCES, 2015). The measurement and analysis of differences…

We draw on novel district-level test score data to describe novel approaches for measuring ethnoracial achievement gaps and assessing trends toward achievement equity from 2009 to 2016. Using SEDA data, we estimate gap trends for each grade over time in each district. We measure trends in both within-district gaps--comparing Black or Hispanic to…

This study presents estimates of Black-White, Hispanic-White, and income achievement gaps using data from two different types of reading and mathematics assessments: constructed-response assessments that were likely more cognitively demanding and state achievement tests that were likely less cognitively demanding (i.e., composed solely or largely…

Test-score data show that both low-income and racial-minority children score lower, on average, on states' elementary-school accountability tests compared with higher-income children or white children. This report explores the relationship between racial and socioeconomic test-score gaps in New England metropolitan areas and two factors associated…

A comparison of Chicago public school students' standardized test scores in 2009-2014 with those of public students across the U.S. reveals two striking patterns. First, Chicago students' scores improved dramatically more, on average, between third and eighth grade than those of the average student in the U.S. This is true for students of all…

While the contents of K-6 basal readers have been recently examined (Dewitz, Leahy, Jones, Sullivan, 2010; Moss, 2008; Moss & Newton, 2002), the contents of secondary school literature anthologies have been vastly ignored in the last 2 decades. Given the Common Core State Standards' division of literary and informational text across content…

This study addressed the effects of multiyear, response-based, tiered intervention for struggling readers in grades 6-8. A sample of 768 sixth-grade students with reading difficulties was randomized to a response-based, tiered-intervention condition or "business as usual," and initial treatment status was maintained over the three-year…

Research on science achievement disparities by gender and race/ethnicity often neglects the beginning of the pipeline in the early grades. We address this limitation using nationally representative data following students from Grades 3 to 8. We find that the Black-White science test score gap (-1.07 SD in Grade 3) remains stable over these years,…

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…

In support of the national movement to improve mathematics instruction and assessment, states and districts are looking for the best tools to measure student progress toward proficiency. There is a national dialogue about how to use 8th-grade measurements like ACT EXPLORE and NAEP as predictors of student success and school accountability. This…

Math Snacks animations and support materials were developed for use on the web and mobile technologies to teach ratio, proportion, scale factor, and number line concepts using a multi-modal approach. Included in Math Snacks are: Animations which promote the visualization of a concept image; written lessons which provide cognitive complexity for…
