Many U.S. students possess only a weak knowledge of fraction arithmetic. I hypothesize that textbooks are a critical reason for students' poor performance on fraction arithmetic. This is not because of what textbooks contain but rather because of what they lack. Distributions of fraction arithmetic problems in textbooks are imbalanced, with…

Many undergraduate students avoid mathematics classes due to math anxiety. This curtails options, particularly STEM majors where workers are needed and jobs are prevalent. This study aimed to investigate whether self-efficacy, mindfulness, and self-compassion predicted math anxiety. Participants of this study were undergraduate students (N = 345)…

English language proficiency (ELP) assessment scores are used by states to make high-stakes decisions related to linguistic support in instruction and assessment for English learner (EL) students and for EL student reclassification. Changes to both academic content standards and ELP academic standards within the last decade have resulted in…

Despite recent efforts to support learners from traditionally minoritized backgrounds in mathematics, inequities in math achievement and participation still exist, particularly for women and people of color. Additionally, much of how math is taught in schools aligns with a particular epistemology that comes from western mathematicians and…

Students' understanding of the meaning of the equal sign develops slowly over the primary grades. In addition to updating their representations of equations to recognize that the equal sign represents an equivalence relation rather than signaling an operation, students need to move beyond full computation to efficiently solve equivalence problems.…

Despite the appeal of promoting and forming collaborative relationships between schools, empirical evidence for an association between school-to-school collaboration and school outcomes is still somewhat lacking. This study utilized data from 76 schools nested within 56 districts in the United States to examine the association between a school's…

Machine learning (ML) methods for causal inference have gained popularity due to their flexibility to predict the outcome model and the propensity score. In this article, we provide a within-group approach for ML-based causal inference methods in order to robustly estimate average treatment effects in multilevel studies when there is cluster-level…

The purposes of this study included conducting a meta-analysis and reviewing the study reporting quality of math interventions implemented in informal learning environments (e.g., the home) by children's caregivers. This meta-analysis included 25 preschool to third-grade math interventions with 83 effect sizes that yielded a statistically…

Intelligent tutoring systems (ITSs) aim to deliver personalized learning support to each learner, aligning with the educational aspiration of many countries, including China. ITSs' personalized support is mainly achieved by providing individual prompts to learners when they encounter difficulties in problem-solving. The guiding principles and…

The current study is a conceptual replication of the influence of an advanced educational opportunity and several student propensities to learn on a college-readiness assessment for mathematics (ACT scores) among an important and under-studied group of students. We focused on a sample of predominantly Black students from economically-disadvantaged…

In previous research, gamified classroom management has been found to improve high school students' classroom participation. This study applied gamification classroom management through a "Class of Oz" in an elementary school to cultivate students' learning. Two classes were randomly assigned to the experimental group, and the other two…

Playing mathematical games helps many senior secondary school students--especially girls--acquire basic mathematical skills, but it can be difficult. Thus, this study examined how gender-related mathematical gameplay affects secondary school students' performance. The design of the study was quasi-experimental. Purposively, a sample of fifty…

The retention of foundational knowledge is crucial in learning and teaching mathematics. However, a significant part of university students do not achieve long-term knowledge and problem-solving skills. A possible tool to increase further retention is testing, the strategic use of retrieval to enhance memory. In this study, the effect of a special…

There is a strong need for fifth-grade students to become proficient in mathematical problem-solving using fractional computations because it will have a lasting impact on student achievement. Traditionally, mathematics is taught inside a brick-and-mortar classroom, grounded in rote memorization of facts, rules, and formulas. In recent years, more…

This quantitative, nonexperimental study used Bronfenbrenner's process-person-context-time (PPCT) model to determine if mathematics scores of underprivileged, minority third- and fourth-grade students attending an inner-city school in a Central Oklahoma school district differed between their traditional 2018-2019 school year and post-lockdown…
