There is no consensus about whether a teacher-centred or student-centred instructional approach is more effective for students' maths achievement. Prior studies have highlighted the role of students' maths self-concept as a predictor and mediator for maths achievement. This study examined whether instructional approaches were related to students'…

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…

School-based learning experiences are often designed with the "typical" student in mind. However, this may not be an optimal approach, given the variability of prior learning that exists in most classrooms. We investigated the variance in achievement within U.S. fourth- and eighth-grade mathematics classrooms using Trends in…

Students living in poverty tend to perform worse in school than their peers from better-off families. This paper examines whether computer availability helps narrow down educational inequalities in Slovakia, using TIMSS and PIRLS data. The results show that computer availability in reading lessons improves reading scores and that the effect is…

Children possess different beliefs regarding their ability to succeed in math and science, as well as different levels of enjoyment and interest in these topics. These motivational processes are important because they often shape learning-related behaviours which in turn predict academic outcomes, over and above previous performance. But, what are…

The aim of this study is examining the relationship between student achievement and bringing interesting materials to the classroom in 4th grade mathematics in Saudi Arabia, Qatar, Turkey, and Singapore. This study used TIMSS 2015 data to investigate the relationship between student achievement and bringing interesting materials to the classroom…

This correlative study examined the role of teacher qualities and working conditions in 4th- and 8th-grade Turkish students' mathematics achievement in TIMSS 2019. Teacher qualifications were defined based on the teacher questionnaire used in TIMSS 2019 and were discussed in three categories: personal characteristics, teacher qualifications, and…

The purpose of this study is to explore elementary educators' perceptions regarding what it means to conceptually understand mathematics, the emphasis teachers place on utilizing evidence-based teaching processes, as identified as effective by National Council of Teachers of Mathematics (NCTM), and how these perceptions influence their…

Declining academic achievement across U.S. schools, particularly in mathematics and science, has prompted several initiatives to increase the quality of teaching in science, technology, engineering, and mathematics (STEM). The National Science Foundation initiated the Innovative Technology Experiences for Students and Teachers (ITEST) program in…

This study presents empirical findings demonstrating predictive validities of noncognitive variables for mathematics achievement among primary and secondary school students from cross-country perspectives. Results based on TIMSS 2015 assessment showed that confidence was a moderately strong predictor of mathematics achievement in all TIMSS…

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…

This paper reports an exploration into Indonesian fourth graders' difficulties in fractions and their relation to the opportunity to learn fractions students got at schools. The concept of "opportunity to learn" is often considered as a framework to investigate possible reasons for students' difficulties. The data for this study was…

This open access book brings together national experts from across the Dinaric region to rigorously review IEA's Trends in International Mathematics and Science Study (TIMSS) 2019 grade four data to develop a multidimensional and culturally sensitive perspective on their TIMSS 2019 primary-level results. The Dinaric region, named after the Dinaric…

Does teacher quality differ within and between countries, and how are measures of teacher quality related to instructional alignment and instructional time in mathematics? Fourth-grade classroom data from the IEA's Trends in Mathematics and Science Study (TIMSS) 2015 revealed that although measures of teacher quality were only weakly related to…

STEM education was a systematic teaching and/or learning process in the STEM fields and a positive correlation existed between STEM education, and the economic prosperity and power of a nation in the globalized world. In recent years, rising concerns have emerged about American STEM education. Many stakeholders wondered that whether the nation has…
