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…

It is well understood that when students are experiencing hunger, their ability to learn suffers. What is less understood is why this is the case and the role of the learning environment. Using Trends in International Mathematics and Science Study (TIMSS) 2019 data, this brief examines how student hunger is correlated with how disorderly the…

While numerous studies have reported the effect of school socioeconomic status (SES) on achievement, the factors that can cause this relationship are not well established. This study is, therefore, an attempt to understand school SES and students' mathematics achievement relationship by assuming that this relationship occurs through a correlation…

We investigated effects of tracking students into higher, more academic, and lower, less academic, school types immediately after primary school (early tracking) instead of having a comprehensive secondary school system (late tracking) on school gender segregation and gender gaps in achievement outcomes. We assumed that, in early tracking…

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…

In TIMSS 2015, while two-thirds of students in grade 4 reported feeling very safe at school, by grade 8, less than half of the students surveyed reported feeling a high level of safety. Overall, girls were more likely to report feeling safe than boys. For both genders, feeling safe at school seemed to be positively related to academic achievement…

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…

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…

International studies suggest that the U.S. ranks below many Asian and European countries in the 21st century in terms of mathematics and science achievement. Few have looked beyond the classroom to understand these differences. Absolute and relative time spent in various out-of-school time (OST) activities may provide one explanation. This study…
