Excellence gaps are differences in advanced education outcomes among student groups. This study replicates and extends an earlier study on the prevalence and magnitude of excellence gaps based on student sex and immigrant status using Grade 8 TIMSS data. Data were included for the 12 countries that have participated in each TIMSS administration…

Globally, the private school share of enrollment increased from about 14 percent in 2000 to about 18 percent in 2019. We estimate the systemic effect of private enrollment share on learning outcomes. Estimates of the systemic effect of private school enrollment capture any competitive effects as well as any differences between public and private…

Absenteeism and students' attitudes toward science have an impact on the exam results among eighth-grade students in Malaysia and Singapore. This study employed weighted least squares and quantile regression techniques on the Trends in International Mathematics and Science Study (TIMSS) 2019 data to analyze the net effect of these two factors in…

Our study is among the first to provide a comprehensive review of cross-national patterns of gender differences in various STEM-related constructs--achievement, beliefs, attitudes, aspirations, and participation, concerning country-level gender equality. We complement our review with empirical analyses utilizing rigorous methodologies and richer…

Collaboration is an aspect of engagement that focuses on learning through group work and having discussions with other learners. Active learning approaches are a way to foster collaborative engagement because they provide more opportunities for interaction among learners. Process Oriented Guided Inquiry Learning (POGIL), a socially mediated active…

This study analyzes how students' reported teaching practices of their teachers and their attitudes towards science are related to the science achievements of four high-performing countries/economies in PISA 2015: Hong Kong, China, Canada, and Finland. A study of these regions can shed light on the commonalities of and differences between the…

We aimed to examine the effect of ICT use, parental support and student hindering on science achievement in Turkey, USA and South Korea with using PISA 2018 data. PISA is one of the biggest international assessment study aiming comparison of students' academic capabilities in science, mathematics and reading among participant countries. For this…

Information and Communication Technology (ICT) engagement, as a multidimensional construct, plays an increasingly important role in education. The main purpose of this research was to explore the effects of ICT engagement factors on science performance across Singapore and Turkey conditional to the sufficient degree of measurement invariance of…

This study examines the direct and indirect relationships between key motivational constructs and science achievement using TIMSS 2019 data sets for Japan, Norway, and the United States. The sample of the study includes 4,446 and 8,698 eighth graders in Japan and the United States, with 4,575 ninth graders in Norway. The structural equation model…

The quality of education is a predictor of a country's economic performance -- which is why comparative international education surveys are important. South Africa performed poorly in the Trends in International Mathematics and Science Study (TIMSS) in 2019. The score of 374 for mathematics and 324 for science is poor compared to the mid-point of…

The aim of this study was to investigate the comparability of feedback across culturally diverse countries by assessing the measurement invariance in PISA 2015 data. A multi-group confirmatory factor analysis showed that the feedback scale implemented in PISA 2015 was not invariant across countries. The intercepts and residuals of the factor model…

International studies of science education, such as the Trends in Mathematics and Science Study (TIMSS), have revealed considerable national disparities in students' achievements in science education. The results have prompted many nations to compare their science education systems and practices to those of others, to gain insights for…

This paper compares the learning gain over one year of schooling among 15-year-old students in Austria and Scotland (United Kingdom). Common metrics for reading, mathematics and science learning, as established by the Programme for International Student Assessment (PISA), are used. In order to overcome the limitations of a cross-sectional,…

PISA has extensively measured student achievement for over 15 years. But cognitive performance is only one aspect of success at school; another is general well-being. The PISA 2015 questionnaire included a comprehensive section on student well-being designed to understand students' mental health, satisfaction with life, aspirations and…

While science self-concepts of secondary school students have received considerable attention, several important aspects of chemistry self-concepts have not yet been understood: gender relations, the impact of students' cultural backgrounds, and the impact of chemistry self-concept on learning processes. In the present study, (i) we could confirm…
