Has the achievement of U.S. students improved over the past half century? Have gaps between racial, ethnic, and socioeconomic groups widened or narrowed? These and similar questions provoke near-constant conversation. But answers are uncertain, partly because research to date has yielded inconsistent findings. In this article, the authors bring…

The International Association for the Evaluation of Educational Achievement (IEA) Research for Education series represents a further effort by IEA to capitalize on it's unique datasets, so as to provide powerful information for policymakers and researchers. Each report focuses on a specific topic and is produced by a dedicated team of leading…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

In poor-performing, resource-constrained education systems, such as South Africa, solutions to improve academic achievement have tended to focus on resources and cognitive factors. An area that requires more attention is the importance of non-cognitive, psychosocial factors and their relationship with academic performance. These factors are…

This study examines the role of self-concept regarding mathematical ability in explaining the gender gap in advanced mathematics performance of US high school students. The study is based on data generated from the Third International Mathematics and Science Study (TIMSS 1995-2015), a large-scale project which investigated the relationship between…

Globally girls' performance in mathematics has improved over the years as measured by TIMSS results. Inconsistency in mathematics performance of boys and girls is still an area of great concern. This study examines the relationship between mathematics achievement and gender of South African Grade 9 learners from TIMSS 2015 data. The data were…

Students' perceived values and costs of learning chemistry influence their performance and intentions of choosing chemistry-related majors or careers. Based on Situated Expectancy-Value Theory, this study adopted a mixed method approach to examine the conceptualization of values and costs among Chinese high school students and identify their…

Due to the fixed school start in Norway in August of the calendar year of students' sixth birthday, the age span in one class is up to twelve months. This can impact academic performance both in the early years and later. In this paper, we investigate the relationship between birth month and mathematics performance by paying attention to the…

Gender differences in math-related professional achievements have been identified as a worldwide problem. Academic achievement assessments, however, have repeatedly revealed gender similarities. The observed gender similarity might be due to biased assessments that heavily rely on reading skills, which favors girls. The current study analyzed 29…

It is widely acknowledged that understanding of science is key to becoming global citizens and to embrace technological advancements. Although research suggests that girl's performance in science has improved over the years, there are still concerns about the under-representation of women in science, technology, engineering and mathematics (STEM)…

Concerns about the breadth of the U.S. income distribution and limited intergenerational mobility have led to a focus on educational achievement gaps by socio-economic status (SES). Using intertemporally linked assessments from NAEP [National Assessment of Educational Progress], TIMSS [Trends in International Mathematics and Science Survey], and…

This study examined how high school students' attitudes toward advanced physics were predicted by their sense of school belonging, and how gender moderated this relationship. The Trends in International Math and Science (TIMSS) 2015 Advanced data, consisting of responses from 12th grade students enrolled in advanced physics courses among nine…

This research examined the experiences of immigrant students and emergent bilinguals in mathematics. The purpose of these studies was to identify, describe, and understand some of the various factors that impact mathematics achievement and success for these student groups through qualitative case studies and quantitative analysis of the 2015 TIMSS…

In the United States (US) and in the United Arab Emirates (UAE) students are still attaining poorly in high school mathematics despite efforts from educational leaders to improve the math curricula both in middle and high schools. Results of the Program for International Student Assessment (PISA) revealed that 31 countries out of 65 had better…

This Brown Center Report (BCR) on American Education is the sixth and final edition in the third volume and the 16th issue overall. The series began in 2000. As in the past, the report comprises three studies. Also in keeping with tradition, the first section features recent results from state, national, or international assessments; the second…
