Trends in International Mathematics and Science Study (TIMSS) 2019 data revealed that Grade 8 science teachers in several Asian countries (Chinese Taipei, Hong Kong SAR, Japan, and South Korea) reported lower job satisfaction levels than the international average. For example, while Japanese Grade 8 students ranked among the highest in science…

One of the main objectives of international large-scale assessments is to make comparisons between different countries, education policies, education systems, or subgroups. One of the main criteria for making comparisons between different groups is to ensure measurement invariance. The purpose of this study was to test the measurement invariance…

This study examines the direct and indirect relationships between key motivational constructs and science achievement using TIMSS 2019 data sets for Japan, Norway, and the United States. The sample of the study includes 4,446 and 8,698 eighth graders in Japan and the United States, with 4,575 ninth graders in Norway. The structural equation model…

This study aims to first investigate the effect of the extreme response style (ERS) which could lead to an attitude-achievement paradox among the countries participating in the Trends in International Mathematics and Science Study (TIMSS 2015), and then to determine the individual- and country-level relationships between attitude and achievement…

This brief examines Trends in International Mathematics and Science Study (TIMSS) science achievement of the 20% highest and the 20% lowest performing fourth and eighth graders in 11 countries. To do so, the authors compare achievement distributions across countries, using measures of relative equality within countries. Such an examination…

International comparative assessments of student achievement are constructed to assess country-level differences and change over time. A coherent understanding of the international trends in educational outcomes is strongly needed as suggested by numerous previous studies. Investigating these trends requires long-term analysis, as substantial…

Modelling ability is one of the essential elements of the latest educational reforms, and Trends in International Mathematics and Science Study (TIMSS) is a curriculum-based assessment which allows educational systems worldwide to inspect the curricular influences. The aims of this study were to examine the role of modelling ability in the…

Purpose: Cross-cultural comparisons based on ordinal Likert-type rating scales have been threatened by response style which is systematic tendencies to respond to items regardless of the item content. So, this study aimed to investigate the effect of extreme response style and acquisance response style on TIMSS 2015 data. Method: The sample of…

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…

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the correlations of science classroom teachings with eighth graders' science…

Since 1995, the International Association for the Evaluation of Educational Achievement (IEA) implemented the Trends in International Mathematics and Science Study (TIMSS) as an international comparative study. This article aims at identifying the correlations of science classroom instructions with TIMSS science achievement of eighth graders among…

Trends in International Mathematics and Science Study (TIMSS) data reveal that setting high standards for the overall mathematics curriculum and ensuring teachers adhere to these standards may not necessarily lead to better learning outcomes for students. There are significant gaps between the intended and implemented grade 8 mathematics curricula…

This study analyzed the responses of Korean students to interest, confidence, value, and instructional clarity in science and mathematics. To achieve this, the raw data of the recent student survey of TIMSS were analyzed. A one-way ANOVA was performed, and a post hoc test was performed. Additionally, a cohort analysis was performed to determine…

In the literature, response style is one of the factors causing an achievement-attitude paradox and threatens the validity of the results obtained from studies. In this regard, the aim of this study is two-fold. Firstly, it attempts to determine which item response tree (IRTree) models based on the generalized linear mixed model (GLMM) approach…

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the affective factors contributing to eighth graders' science achievement in TIMSS…
