The overall aim of this study was to examine the different self-reported students' socioeconomic status (SES) measures in the Trends in Mathematics and Science Study (TIMSS) in comparison to national SES measures obtained from Swedish official registers. A further aim was to determine if the same conclusions could be drawn if different student…

Using data collected from 4329 students in the 2015 iteration of the Trends in Mathematics and Science Study (TIMSS), we explore two mediators for the relationship between socioeconomic status (SES) and TIMSS-results in mathematics among Norwegian fifth graders. First, we explore how the students' motivation and self-concept mediate the…

This study investigated the status of equity in mathematics education in Hong Kong based on data from TIMSS 2011 to 2019 and the changes in education equity across the three cycles. The effects of various student-, family-, and school-level variables on students' mathematics achievement were examined and compared using multilevel modeling. Results…

An extensive body of research exists on the background characteristics that predict learner achievement. However, in South Africa, little attention has been paid to the level of educational aspirations and the factors that shape the level of aspirations. Using a bio-ecological systems theory of development, we explored the role of gender,…

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…

Today's economy demands higher order thinking skills (HOTS), and the public education system has a critical role in supporting students' acquisition of HOTS. Yet, numerous studies documented inequity in access to higher quality instruction that promotes HOTS, which could result in wide test score gaps in HOTS. In this study, I examined test score…

Socioeconomic status (SES) is considered a major predictor of student and school achievement. In most cases, SES is not malleable or available for manipulation to improve students' learning and achievement. Therefore, we explored other student and school-related factors that may be malleable to reduce achievement differences between students and…

Equity is a fundamental value and guiding principle of education policy and practice, but it is not necessarily actualised in schools and education systems around the world. There are large variations across PISA-participating countries and economies in the magnitude of the difference that socio-economic status makes in students' learning,…

Background: The present study investigates what factors related to the school context influence student achievement on TIMSS mathematics tests across countries. A systematic review of the literature on PIRLS, TIMSS, and ICCS was conducted upstream to identify those school, teacher, and classroom factors shown to be useful predictors of student…

It is well documented that academic achievement of students from families of low socioeconomic status (SES) tends to be below their more socially advantaged peers. Several studies have identified factors and conditions that facilitate academic success for disadvantaged students (i.e., promote academic resilience). However, one of the main…

Achievement in mathematics of eighth-grade students is modeled as a function of within-school, between-school and cross-country differences. The data were obtained from 217,728 students, within 7,216 secondary schools, in 48 countries, who participated in the 2007 Trends in International Mathematics and Science Study. Multilevel analysis showed…

The authors explored how gender and socioeconomic status (SES) predicted physics achievement as mediated by metacognition and physics self-efficacy. Data were collected from 338 high school students. The model designed for exploring how gender and SES-related differences in physics achievement were explained through metacognition and physics…

This study examined the individual, class, and school level variability of the students' science achievement. It was hypothesized that there are school or teacher effects which contribute toward explaining achievement differences, besides the student level differences. Owing to the nested structure of the data in Trends in International…

In this study, we analyse the predictive power of home and school environment-related factors for determining pupils' aggression. The multiple regression analyses are performed for fourth- and eighth-grade pupils based on the Trends in Mathematics and Science Study (TIMSS) 2007 (N = 8394) and TIMSS 2011 (N = 9415) databases for Slovenia. At the…

This paper reports on secondary analysis of TIMSS 2003 data with the aim of explaining the difference in science achievement of Korean and South African learners. The question asked by this research, i.e. which factors at various educational levels influence science achievement in Korea and South Africa respectively, is addressed from the…
