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…

Researchers have long postulated the existence of a big-fish-little-pond effect (BFLPE) in which a student's relative academic standing in class or school affects his or her academic self-concept. Few studies, however, use causal research designs to identify whether the BFLPE exists and whether it is generalizable across a wide variety of…

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…

The underrepresentation of women in science, technology, engineering, and mathematics (STEM)-related fields remains a concern for educators and the scientific community. Gender differences in mathematics and science achievement play a role, in conjunction with attitudes and self-efficacy beliefs. We report results from the 2011 Trends in…

Bullying victimisation is a reality in most schools around the world, with thousands of students being victimised on a daily basis. Given the prevalence of bullying victimisation at school, examination of what might prompt or prevent such behaviours is required. Therefore, this study examined the relationship of a number of individual and…

This article presents a new perspective on measuring gender differences in the large-scale assessment study Trends in International Science Study (TIMSS). The suggested empirical model is directly based on the theoretical competence model of the domain mathematics and thus includes the interaction between content and cognitive sub-competencies.…

On international comparisons, the development of Oman's education system in terms of the increase in educational enrolment rates and in the level of teacher qualifications has been remarkably rapid. Almost 100% access to basic education has been achieved, and almost all students progress onto post-basic education. A report from the World Bank in…

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…

This dissertation explores how country-level cultural values are associated with gender differences in the enrollment in and completion of science, technology, engineering, and mathematics (STEM) Massive Open Online Courses (MOOC), national achievement in mathematics and science, and students' science achievement. Study 1 explored how gender-equal…

The purpose of this study is to compare and contrast student, teacher, and school factors that are associated with student mathematics achievement in South Korea and the United States. Using the data from the Trends in International Mathematics and Science Study (TIMSS) 2011, this study examines factors that are linked to teachers who deliver…

Relationships among motivational constructs from the 2011 Trends in International Mathematics and Science Study (TIMSS 2011) were investigated for eight-graders in all the five participating African countries, representing 38,806 (49 % girls). First, we investigated the psychometric properties (factor structure, reliabilities, method effect, and…

The detrimental effects of school violence on students' physical and emotional health are well studied, and research has shown that school violence affects students in every nation across the globe. However, few cross-national studies have compared direct, physical forms of school violence to indirect, emotional forms such as teasing. Using…

Due to the scarcity of cross-cultural comparative studies in exploring students' self-efficacy in science learning, this study attempted to develop a multi-dimensional science learning self-efficacy (SLSE) instrument to measure 316 Singaporean and 303 Taiwanese eighth graders' SLSE and further to examine the differences between the two student…

The prevalence of women in the teaching profession has been claimed by various scholars to be responsible for the low school performance among boys. Based on this claim there have been widespread calls for increasing the share of male teachers as a means of improving boys' school performance. There is, however, very little empirical evidence…
