Bullying generally has been shown to have a number of negative outcomes for student well-being. IEA's TIMSS (Trends in Mathematics and Science Study) 2019 data shows that cyberbullying is correlated with traditional forms of bullying and is particularly relevant in more recent times. The relationship between the two forms of bullying is strong and…

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…

Before school closures due to the COVID-19 pandemic, the frequency with which teachers used computer activities to teach a class varied across education systems. However, many teachers across the board reported the need for professional development to teach using technical devices. Using results from TIMSS (Trends in International Mathematics and…

This article, based on a 2-year study of working strategically with Years 5 to 8 priority learners, concludes that what is effective writing instruction for all students is particularly effective for priority learners. It also suggests, however, that knowing your students well and making adaptations to some dimensions of effective writing…

Women's underrepresentation in mathematics-related careers continues to concern policymakers, economists, and educators. This study addressed the issue by examining data from two international databases, namely IEA's "Trends in International Mathematics and Science Study 2015," and the World Economic Forum's "Global Gender Gap…

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…

The OECD Future of Education and Skills 2030 (E2030) project's overall goal is that of looking to the future in terms of how school curricula should evolve given the technological advances and other changes that societies are now facing. Towards that end, the E2030 project centres on the idea that education needs to equip students with the…

The International Association for the Evaluation of Educational Achievement's (IEA) mission is to enhance knowledge about education systems worldwide, and to provide high-quality data that will support education reform and lead to better teaching and learning in schools. In pursuit of this aim, it conducts, and reports on, major studies of student…

The objective of this paper is to investigate differences in the academic achievement of students who report experiencing both bullying and a lack of belonging within their school settings as compared to their peers who report neither of these experiences. This study will expand upon existing research by using a cross-national sample of students…

This study presents empirical findings demonstrating predictive validities of noncognitive variables for mathematics achievement among primary and secondary school students from cross-country perspectives. Results based on TIMSS 2015 assessment showed that confidence was a moderately strong predictor of mathematics achievement in all TIMSS…

Girls and women, especially the most vulnerable, are more likely to be excluded from education than their male counterparts. Exclusion and gender disparities in access to and performance in education are also observed among immigrant children, with immigrant girls often being the most disadvantaged. Data from the International Association for the…

We utilised four waves of TIMSS data in addition to the information we have collected on countries' educational systems to examine whether different degrees of standardisation, differentiation, proportion of students in private schools and governmental spending on education influence students' math achievement, its variation and socioeconomic…

Background: The present study investigates what factors related to the school context influence student achievement on TIMSS mathematics tests across countries. A systematic review of the literature on PIRLS, TIMSS, and ICCS was conducted upstream to identify those school, teacher, and classroom factors shown to be useful predictors of student…

The different strategies and methodologies used by teachers in their day-to-day activity may have an impact on the academic performance of their students. Indexes constructed to summarize how teachers address different teaching tasks can be used to quantify the teaching activities' associations with academic results. In the IEA's Trends in…

Writing is a demanding, multidimensional process that is, cognitively and socially, highly complex. Success in writing is vital to success in education and in the workforce. Writing is increasingly used to demonstrate learning through schooling and has the potential to contribute toward understanding and learning in the content areas. The project…
