This study capitalizes on response and process data from the computer-based TIMSS 2019 Problem Solving and Inquiry tasks to investigate gender differences in test-taking behaviors and their association with mathematics achievement at the eighth grade. Specifically, a recently proposed hierarchical speed-accuracy-revisits (SAR) model was adapted to…

It is well understood that when students are experiencing hunger, their ability to learn suffers. What is less understood is why this is the case and the role of the learning environment. Using Trends in International Mathematics and Science Study (TIMSS) 2019 data, this brief examines how student hunger is correlated with how disorderly the…

This study comprises two meta-analyses conducted to investigate relations between socioeconomic status (SES) and academic achievement, with a focus on macro-level, micro-level, and methodological moderating variables in primary and secondary education. The first meta-analysis is based on 326 empirical studies with 949,699 students from 47…

The purpose of the present study was to examine the effect of individual and school average achievement on students' self-concept in science. The data of the last four Trends in International Mathematics and Science Study (TIMSS) cycles were used, and a two-stage individual data meta-analysis was conducted to examine the relationship between…

Background: Home mathematics environment (HME) research has focused on parent--child interactions surrounding numerical activities as measured by the frequency of engaging in such activities. However, HME survey questions have been developed from limited perspectives (e.g., "Early Childhood Research Quarterly," 27, 2012, 231;…

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…

It is generally understood that both clear teacher instruction and orderly classroom climates support student achievement in mathematics. However, to what extent does instructional clarity "compensate" for classroom disorder? In this exploratory study, we analyse data from 8,864 Year 8 students sampled by TIMSS 2019 to investigate the…

A wide range of reforms to improve the teaching capacities of pre-service and in-service teachers have been carried out in Kosovo. In assessing the success of these previous interventions, large-scale assessment data is invaluable. In 2019, 4754 students from 145 schools participated in the TIMSS assessment. Results reveal that student's…

Using data from the Trends in International Mathematics and Science Study (TIMSS), this study examines the student and school characteristics that contribute to students' mathematics performance in early elementary school in Chile. Previous research has separately analyzed the association of student and school factors with mathematics performance.…

There is a common belief that the more the time students spend in the classroom the more they learn; a conception which has been supported by considerable empirical research. However, most of these studies are correlational, which does not provide solid support for their conclusions. In this research work we intend to go a step further in the…

Boys in the Kingdom of Saudi Arabia consistently and significantly underperform compared to girls across different grades and subjects, forming one of the largest gender gaps in student achievement in the world. Saudi Arabia offers a unique setting in which boys and girls attend separate schools on a universal basis starting from grade 1. This…

This research aims to scrutinize the moderating effect of teacher interaction on the relationships between students' self-efficacy and achievement in mathematics in three countries, Korea, Singapore, and the USA. We analyzed the Trends in International Mathematics and Science Study (TIMSS) 2015 data with hierarchical linear modeling. The findings…

Using data from the Trends in International Mathematics and Science Study (TIMSS) 2015 assessment of fourth-grade students in 32 countries, a series of mean comparisons and regression analyses were conducted to determine (1) the gender gap in students' self-concept in mathematics; (2) to what extent student achievement, student gender, and…

The study addresses the phenomenon of science teachers' innovative work activities referring to Rogers' Diffusion theory of innovation (RDI) based on four countries (Sweden, Norway, Lithuania, Italy) TIMSS 2015 data set. The countries were chosen according to different criteria: 1 -- years of teaching; 2 -- gender; 3 -- hours spent for…

Extant literature has demonstrated the importance of individual and school-related factors in improving mathematics achievement. Despite this, there is still a gap in research to understand the mediating role of educational aspiration in mathematics achievement. The aim of the present study is to test the relationship between self-efficacy, school…
