Using the test scores of more than 2,250,000 students who participated in the American Mathematics Competitions (AMC) from 2009 to 2019, this study examined the direction and magnitude of the trends in gender disparity in participation and high achievement in self-select mathematics exams. The results of this study indicated that the male to…

This study evaluated the forecasting accuracy of trend estimation methods applied to time-series data from computer adaptive tests (CATs). Data were collected roughly once a month over the course of a school year. We evaluated the forecasting accuracy of two regression-based growth estimation methods (ordinary least squares and Theil-Sen). The…

Although Montessori is the most common unconventional education model, no multi-state study has compared standardized test proficiency of Montessori schools with districts. Here we report on this for the 10 states/regions with the most public Montessori schools (n = 195). In 3rd grade, Montessori schools were less proficient in math but more…

More than a quarter of all U.S. students in grades K-12 are Latinx. Examining what Latinx texts are included in classroom literature anthologies is essential to ensuring cultural representativeness of the increasing Latinx student population, especially in states such as Texas and California, whose Hispanic student population is more than 40…

Although Montessori is the most common unconventional education model, no multi-state study has compared standardized test proficiency of Montessori schools with districts. Here we report on this for the 10 states/regions with the most public Montessori schools (n = 195). In 3rd grade, Montessori schools were less proficient in math but more…

Different approaches are employed when teaching environmental issues. One approach, termed the "environmental scientific approach," perceives environmental education as part of life or earth sciences, providing factual, scientific knowledge. Another approach, termed the "environmental sustainability citizenry approach",…

This paper examines national gaps and trends in geography achievement in eighth grade from 1994 to 2018. Statistical models comprising student- and school-level variables were developed to predict achievement using data provided by the National Assessment of Educational Progress (NAEP). Although there were statistically significant relationships…

The International Large-Scale Assessment (ILSA) is a rapidly growing field in education which has gained considerable attention of stakeholders across the globe. Historically, ILSA emerged from the developed context which has drifted to the developing contexts in a short span of time due to globalisation. Pakistan has participated in ILSA (i.e.,…

Homework is a common instructional practice that is used to motivate students, develop students' studying skills and habits, inform parents about student learning, and increase student achievement. Homework provides an opportunity for students to revisit daily topics, and improve students' understanding of math concepts and problem-solving skills,…

The number of charter schools grew rapidly for a quarter-century after the first charter opened its doors in 1992. But since 2016, the rate of increase has slowed. Is the pause related to a decline in charter effectiveness? To find out, the authors tracked changes in student performance at charter and district schools on the National Assessment of…

This article reports on two professional development programs for mathematics teachers and their effects on student achievement. The projects' design and their implementation within a larger municipality in Sweden, working together with over 90 teachers and 5000 students in elementary school, are described by using a set of core critical features…

We use a quadratic equation to estimate trends in cohort performances in the charter and district sectors on the National Assessment of Educational Progress in 4th and 8th grade between 2005 and 2017. Data consist of over four million test observations of nationally representative samples of students on seven separate math and reading tests. We…

Educational inequality is a highly debated yet empirically understudied topic in Malaysia. This paper examines the patterns and trends of academic achievement gaps by student social groups in Malaysia, drawing upon nationally representative data for the most recent four cohorts (1999, 2003, 2007, and 2011) of eighth-grade Malaysian students from…

South Africa participated in TIMSS from 1995 to 2015. Over these two decades, some positive changes have been reported on the aggregated mathematics performance patterns of South African learners. This paper focuses on the achievement patterns of South Africa's high-performing Grade 9 learners (n = 3378) in comparison with similar subsamples of…

Of the handful of national studies tracking trends in adolescent substance use in the United States, only the Health Behavior in School-Aged Children (HBSC) study collects data from 6th through 10th graders. The purpose of this study was to examine trends from 1998 to 2010 (four time points) in the prevalence of tobacco, alcohol, and marijuana use…
