The quality of diagnostic profiles and probability assignment depends on the validity of the proposed attributes and Q-matrix. The rule-space method (RSM), one of diagnostic classification models, provides the quality indices of diagnostic profiles, such as the classification rate and the squared Mahalanobis distance. The study aims to further…

Background: Numerous efforts worldwide have been made to increase diversity in engineering and computer science (ECS), fields that pay well and promote upward mobility. However, in the United States (U.S.), females and students from underrepresented racial/ethnic minority groups (URM) still pursue ECS training far less than do their peers. The…

While achievement gaps have been well-established, much remains to be understood about the manner and extent to which school leadership either increases or decreases student access to opportunity to learn. The current study uses nationally representative samples of U.S. and Flemish students in Grade 4 from the 2011 Trends in International…

Education researchers have long wrestled with the interplay of oppressive structures and individual agency in reproducing, sustaining, and contesting marginalization. In this article, we suggest that Weis and Fine's construct of critical bifocality may assist researchers in understanding and addressing marginalization in mathematics education. We…

Algebraic thinking and strategy flexibility are essential to advanced mathematical thinking. Early algebra instruction uses 'missing-operand' problems (e.g., x - 7 = 2) solvable via two typical strategies: (1) direct retrieval of arithmetic facts (e.g., 9 - 7 = 2) and (2) performance of the inverse operation (e.g., 2 + 7 = 9). The current study…

Problems of developing subject education and science have become more acute during different social changes. The most problematic is the teaching of exact disciplines, including mathematical disciplines (mathematics, algebra, geometry), which form knowledge for working in high-tech industries. It is worth noting that the methodology of teaching…

Students in the United States are not achieving in mathematics as indicated on the NAEP (2019) exams and other measurements of student achievement (NCES, 2019; OECD, 2019; O'Dwyer, et al., 2015). Mathematically gifted and promising students are especially impacted by this phenomenon, though it is not exactly known what factors contribute to…

Helping teachers become more effective in the classroom is a high priority for educators and policymakers. A growing body of evidence suggests that individualized coaching focused on general teaching practices can improve teachers' instruction and student achievement. However, little is known about the benefits of specific approaches to coaching,…

Helping teachers become more effective in the classroom is a high priority for school leaders and policymakers. This Study Highlights presents key findings from a study that examined a promising strategy for improving teachers' effectiveness: providing individualized coaching using videos of teachers' instruction for reflection, practice, and…

In this paper we examine academic recovery in 12 mid- to large-sized school districts across 10 states during the 2021-22 school year. Our findings highlight the challenges that recovery efforts faced during the 2021-22 school year. Although, on average, math and reading test score gains during the school year reached the pace of pre-pandemic…

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…

Analysis of consistent Zearn Math users and a comparable group of non-users in District of Columbia Public Schools (DCPS) shows that students who used Zearn Math consistently had higher levels of academic growth than similar students with low- or no-usage. This analysis used two quasi-experimental methods, Coarsened Exact Matching (CEM) and fixed…

Measurement and statistical investigation are areas of mathematics visibly neglected in educational intervention research, particularly studies involving students with or at risk for mathematics difficulties (MD). This shortage is concerning given the importance these areas hold in students' pursuit of mathematical proficiency. This study…

The purpose of this study was to examine the relationship between high school students' athletics participation, mediated by engagement, and their academic achievement. The study sought to determine if increased athletics participation, and a self-reported increased sense of engagement at school, resulted in higher SAT test scores for high school…
