This study focused on the relationships between teacher characteristics and students' mathematics achievement in EU countries, including Hungary, Italy, Lithuania, Malta, Slovenia, Sweden, and Turkey, which are the only EU countries participated in TIMSS 2015 at the eighth-grade level. The data consisted of the sample of 31,969 eighth-grade…

This study examined outcomes for AP® Calculus and AP Physics students on the 2015 Trends in International Math and Science Study (TIMSS) relative to other participating countries and other advanced math and science students in the United States. Compared to other countries in the study, AP Calculus BC and AP Physics C: EM students outperformed all…

This open access book presents original research on effective and equitable teacher practice in mathematics and science education across Nordic countries. It focuses on three key aspects of teacher practice: what teachers teach, how teachers teach, and how teachers assess their students. To provide a comprehensive understanding of teacher…

In the educational literature on peer effects, attention has been brought to the fact that the mechanisms creating peer effects are still to a large extent hidden in obscurity. The hypothesis in the study reported in this article was that the Frame Factor Theory (FFT) can be used to reveal such mechanisms. Using data from the Swedish TIMSS 2015 (N…

This study examined how high school students' attitudes toward advanced physics were predicted by their sense of school belonging, and how gender moderated this relationship. The Trends in International Math and Science (TIMSS) 2015 Advanced data, consisting of responses from 12th grade students enrolled in advanced physics courses among nine…

Classrooms with higher teaching quality were associated with higher learning outcomes in mathematics and science. Classrooms where teachers reported high degrees of limitations to teaching in the classroom--including disruptive students or students with language barriers--were associated with lower learning outcomes. These are two of the important…

The study aimed to determine the extent of associations of physics, mathematics, and between physics and mathematics based on the results of the 2007, 2011, and 2015 Trends in Mathematics and Science Survey achievement tests. Utilizing educational data mining and correlational data analysis (significance set at [alpha] = 0.05), this study's…

This case study investigates, at three Swedish schools, primary school students' knowledge of the equal sign. The schools were chosen as representatives of schools whose students have different socioeconomic backgrounds. The data consist of Grade 3 and 6 students' responses to an assessment form based on Matthews et al. ("JRME,"…

International large-scale assessments (ILSAs) have become an important part of the Swedish evaluation system. It is therefore of crucial importance to validate national measures of Swedish students' achievement with their ILSA test scores. Here, we offer results from such a validation study based on Swedish students' test scores in IEA's Trends in…

Women's underrepresentation in mathematics-related careers continues to concern policymakers, economists, and educators. This study addressed the issue by examining data from two international databases, namely IEA's "Trends in International Mathematics and Science Study 2015," and the World Economic Forum's "Global Gender Gap…

The International Association for the Evaluation of Educational Achievement's (IEA) mission is to enhance knowledge about education systems worldwide and to provide high-quality data that will support education reform and lead to better teaching and learning in schools. In pursuit of this aim, it conducts and reports on major studies of student…

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…

The aim of this study was to examine the association between students' TIMSS (Trends in Mathematics and Science Study) science achievement, and students' school achievements, in terms of national tests and grades from school years 6 and 9. Further to examine the association with TIMSS science achievement and different subgroups of students based…

While professional development has been emphasised in many countries, few comparative studies have examined the degree of teachers' participation in professional development and its effect on teachers. Using the TIMSS 2007 data, this study analyses to what extent teachers participated in professional development in 50 TIMSS countries and examines…

This article addresses the conceptual question "what is lesson study?" as an issue that arises in the context of the globalisation of lesson study as a method for improving teaching and learning beyond its presumed origins in the Japanese education system. To what extent can adaptations of the method in different national settings be…
