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…
