This study analysed secondary TIMSS 2019 data for respondents from South Africa and proposed a model containing ten constructs; nine independent variables (socio-economic status and eight variables about safety aspects in schools) and one independent variable (mathematics achievement). Qualitative data was also collected using interviews and field…

Research related to the "teacher characteristics" dimension of teacher quality has proven inconclusive and weakly related to student success, and addressing the teaching contexts may be crucial for furthering this line of inquiry. International large-scale assessments are well positioned to undertake such questions due to their…

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 aim of this study was to explore principals' perceptions of school practices that have ethical meaning through a transnational perspective based on the 8th grade TIMSS 2015 international assessment. The sample comprised 8353 principals from 8353 different schools and 280,130 students that participated in the TIMSS 2015 survey. We used…

The aim of this study is to investigate the relationship between a variety of non-cognitive factors and the mathematics performance levels of eighth grade students in the Trends in International Mathematics and Science Study (TIMSS). The sample group consists of 4077 Turkish students who took part in TIMSS 2019. Data were collected using the…

This study aims to investigate the effects of school-level and student-level variables on Mathematics achievement of Turkish students. The study adopted quantitative research design. The participants were composed of 4498 students in 146 schools. Both schools and students were selected randomly, and they took part in the study on voluntary basis.…

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 book presents the main findings of a study on school learning environments and student outcomes, which the World Bank conducted in 2019 in three regions of the Russian Federation. Using data collected through the [Organisation for Economic Co-operation and Development] OECD School User Survey and the pilot "Trends in Mathematics and…

School safety is an important factor in schools. Data from the IEA's Trends in International Mathematics and Science Study (TIMSS) indicate that perceptions of school safety are directly related to academic success. School safety seems to be particularly relevant for immigrant students, as their perceptions of safety appear to be more strongly…

School bullying is a complex social phenomenon that negatively impacts the psychosocial well-being of students, as well as the overall culture and climate of schools. Designing appropriate interventions to combat bullying in South African schools requires nuanced information about this phenomenon. This paper examines the extent and nature of…

International research has shown that the quality of school leadership and management (SLM) is important for teaching and learning, particularly in schools where there is acute resource deprivation. This article explores the relationship between leadership and academic achievement in South African secondary schools with varying socio-economic…

Surveys like the recent Trends in International Mathematics and Science Study (TIMSS) and Progress in International Reading Literacy Study (PIRLS) enable educators, policy makers and the wider community to compare Australian students with each other, as well as their counterparts across the world. An essential part of a positive school climate…

This study concerns the assessment of the effects of Index of Principals' Perception of School Climate (PPSC), intimidation of students and gender in Moroccan public schools on student performance in science. The study focused on fourth grade students who participated in the TIMSS 2007. The objective of this study is to answer the following…

We study whether changes in school emphasis on academic success (SEAS) and safe schools (SAFE) may explain the increased science performance in Norway between TIMSS 2007 and 2011. Two-level structural equation modelling (SEM) of merged TIMSS data was used to investigate whether changes in levels of SEAS and SAFE mediate the changes in science…
