This Statistics in Brief (SiB) uses data from the 2011 and 2019 Trends in International Mathematics and Science Study (TIMSS), and explores how achievement gaps between high- and low-performing 4th- and 8th-grade students in the U.S. and other education systems have changed over time. Achievement gaps are defined as the differences in scores…

The consistent prevalence of computer science in our society and the urgent need for STEM professionals in the U.S. raised the need for computer science education at the K-8 level. Researchers have examined the challenges, possible approaches, and contents of teaching computer science. However, there has been limited research on teachers'…

The main objective of this research is to determine the perception of elementary school students on school security by means of metaphors. In order to achieve this objective, the participants were asked to write down their metaphor on the "school security". Raw data obtained by completing sentences such as "I think the school…

The Native American Astronomy Outreach Program (NAAOP) at Lowell Observatory is an in-class STEM enrichment program that pairs astronomers with 4th-8th grade teachers at Native-serving schools in northern Arizona. The astronomer works with the teacher to present hands-on astronomy activities to their class with the goal of getting students excited…

The purpose of this study was to evaluate the "Wit and Wisdom" ("WW") curriculum's impact on District A's student literacy in Tennessee, compare its effectiveness with similar districts, and analyze teacher perceptions, including variations in curriculum favorability, self-efficacy, and implementation. Spanning the academic…

Family socioeconomic status (SES) has a significant influence on children's academic success and is related to parents' attitudes toward education. Moreover, according to the expectancy-value theory, parental expectations are linked to their children's perceptions of school, which, in turn, influences the way their children invest themselves in…

This article explains the process behind estimating a National Education Cost Model (NECM) and generating from that model projections of per-pupil costs to achieve 2016 national average outcomes (reading and math grades 3 to 8) across all districts in the United States, from 2019-20 to 2020-21. This article is a follow-up to a preliminary report…

In this brief we examine how variability in students' math and reading test scores changed across the pandemic, including whether increased dispersion was concentrated at one part of the test score distribution. Using reading and math assessment data from a sample of 8 million students in grades 3-8 in 24,000 public schools who took MAP Growth…

The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, "The Widening Achievement Divide during COVID-19." The authors investigated two main research questions in this brief: (1) To what degree have students' reading and math…

The purpose of this single descriptive case study was to describe how an externship program in the central United States impacts K-8 teachers' investment in and integration of work-based learning (WBL) practices in the classroom. The need to investigate how best to encourage teachers to buy into WBL is driven by misalignment among teacher…

Given the important role played by students' spatial reasoning skills, in this paper we analyse how students use these skills to solve problems involving 2D representations of 3D geometrical shapes. Using data from in total 1357 grades 4 to 9 students, we examine how they visualise shapes in the given diagrams and make use of properties of shapes…

Although prior knowledge is an important predictor of future performance in mathematics, few studies have analyzed which areas of the subject are most critical. Most evidence is based on small- and medium-scale studies from developed countries, with results that cannot be generalized. We explore which areas of mathematics are the most important…

This brief examines Trends in International Mathematics and Science Study (TIMSS) science achievement of the 20% highest and the 20% lowest performing fourth and eighth graders in 11 countries. To do so, the authors compare achievement distributions across countries, using measures of relative equality within countries. Such an examination…
