Using the United States data from the 2019 Trends in International Mathematics and Science Study, which included a total of 9924 randomly selected students in grade eight from 325 randomly selected schools, the present study examined the relationship between the students' attitudes toward mathematics and the mathematics achievement of the…

This open access book uses multiple IEA Assessments to examine the relationship between socioeconomic segregation between classrooms and student outcomes. By examining Socioeconomic status (SES) segregation between classrooms as well as between schools, it produces a more accurate estimate of student sorting. Further, this study examines 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…

This study examined the factors that determined the science achievement of fourth-grade students on the Trends in International Mathematics and Science Study (TIMSS) 2019 in the USA. The data were retrieved from the TIMSS international database and imported to the R program for manipulation. The EdSurvey package was used to conduct multilevel…

In this study, the effects of some student (e.g., gender, bullying, etc.) and school variables (e.g., emphasis on academic achievement, clarity of teaching, etc.) on the TIMSS 2015 science and mathematics achievement of eighth grade students in Türkiye were examined by controlling for the socioeconomic status of the students at the student and…

This is the second of 2 reports that look at the results of TIMSS 2023 and Australia's performance. This report, Volume II, presents the results from the contextual questionnaires, and examines the home, school, and classroom contexts in which learning and achievement occur, as well as student attitudes. Each chapter focuses on different…

This Brown Center Report (BCR) on American Education is the sixth and final edition in the third volume and the 16th issue overall. The series began in 2000. As in the past, the report comprises three studies. Also in keeping with tradition, the first section features recent results from state, national, or international assessments; the second…

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 examined the associations between school entry skills and science achievement at both the student and school levels among fourth-grade students in South Korea, Singapore, Japan, Chinese Taipei, and Hong Kong. Data of the five Asian regions in the 2015 Trends in International Mathematics and Science Study (TIMSS) were analysed. Variables…

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…

School climate which is strongly related with the students' outcomes includes some of the components, among which disciplinary climate in schools was expressed as the dominant one. Safety and order in schools which is strongly related with the physical and emotional security stated as one of the indicator of disciplinary climate in schools. In…

This study examined the relationships among school leadership practices, parental involvement, disciplinary climate, students' perceptions on reading, and student achievement with sample obtained from the combined data of Progress in International Reading Literacy Study (PIRLS) and Trends in International Mathematics and Science Study (TIMSS) 2011…

The Council of the European Union has set the goal of reducing low achievement in reading, mathematics and science among 15-year-olds to less than 15 % by 2020. How are European countries going to achieve this? One of the key elements in the learning process is the instruction time available to students. In fact, not only the quality of…

This report examines the recommended minimum instruction time in full-time compulsory general education in 2016/17 in 42 European education systems. It includes national diagrams illustrating the data by country and by subject. The comparative overview examines the policy changes that have taken place over the last year regarding the recommended…
