Spatial thinking is an important predictor of mathematics. However, existing data do not determine whether all spatial sub-domains are equally important for mathematics outcomes nor whether mathematics-spatial associations vary through development. This study addresses these questions by exploring the developmental relations between mathematics…

Children from low-income families often enter kindergarten academically behind their higher income peers. Recent findings also indicate gaps in social-emotional aspects of school readiness, raising questions about cross-domain relations. Using a subsample (N = 3,485) of 3- and 4-year-olds attending center-based programming in the Head Start Impact…

State accountability systems assume standards based instruction and test content are highly aligned and opportunities to learn the content exist equally for all students. This alignment between content taught and tested is important to understand achievement, yet it is rarely examined. Teachers from Grades 3 to 8 participated along with students…

The Stanford Educational Data Archive (SEDA) is the first data set to allow comparisons of district academic achievement and growth from Grades 3 to 8 across the United States, shining a light on the distribution of educational opportunities. This study describes a convergent validity analysis of the SEDA growth estimates in mathematics and…

Potential differences in achievement between female and male students have always been an interesting topic in educational research, as well as having policy and economic implications. This study provides an overview of the so-called "gender gap" in mathematics and science knowledge, based on an in-depth analysis of both extremes of…

If we wish to embed assessment for accountability within instruction, we need to better understand the relative contribution of different types of learner data to statistical models that predict scores and discrete achievement levels on assessments used for accountability purposes. The present work scales up and extends predictive models of math…

We explore the effects of a statewide policy change that increased the number of high school math courses required for admission to four-year public universities in North Carolina. Using data on cohorts of eighth-grade students from 1999 to 2006, we exploit variation by district over time in the math course-taking environment encountered by…

The provision of high-quality early mathematics instruction and intervention is critical to ensure that all students are on track for academic success. Given this, identifying and utilizing assessments that can enable the detection of nonresponse to mathematics instruction is a critical aspect of early intervention. To this end, the current study…

Abstract In a technologically driven society, math and science students in the United States are falling further and further behind their international counterparts, resulting in an influx of STEM focused, reformed K-12 schools, including schools focused on project-based learning (PBL). This article reports a study of the effectiveness of PBL on…

The aim of this research was to study the effect of activity-based teaching and traditional method of teaching on students' achievement in the subject of Mathematics at elementary stage. The research was experimental based on pre-test, post-test control group design. Two units of geometry were selected from seventh grade Mathematics for this…

Women's underrepresentation in mathematics-related careers continues to concern policymakers, economists, and educators. This study addressed the issue by examining data from two international databases, namely IEA's "Trends in International Mathematics and Science Study 2015," and the World Economic Forum's "Global Gender Gap…

This research examines online course-taking in high schools, which is increasingly used by students falling behind in progress toward graduation. The study looks inside educational settings to observe how online courses are used and assess whether students gain academically through their use. Drawing on 7 million records of online instructional…

Although basing instruction on learning trajectories (LTs) is often recommended, there is little direct evidence regarding the premise of a LT approach--that instruction should be presented (only) one LT level beyond a child's present level. We evaluated this hypothesis in the domain of early shape composition. One group of preschoolers, who were…

Based on longitudinal data (n = 338) from the German National Educational Panel Study (NEPS) competence development (mathematics and language) of three groups with different mathematical preconditions (+/- 1 SD) were compared between age 4 to 10. Groups were composed by first measurement of mathematical achievement in pre-school age (5/6 years).…

Diverse stakeholders have an interest in understanding how teacher characteristics--their preparation and experience, knowledge, and mind-sets and habits--relate to students' outcomes in mathematics. Past research has extensively explored this issue but often examined each characteristic in isolation. Drawing on data from roughly 300 fourth- and…
