Using expert reviews and item response theory (IRT), this study evaluated the language- and culture-related construct-irrelevant variance and reliability of the 2019 TIMSS sense of school belonging scale (SSBS) for grades 4 and 8. The five items of the SSBS, which were identical for both grades, were reviewed for the language- and culture-related…

Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or might instead be a methodological artifact reflecting item response theory (IRT) model misspecification.…

This study provides a comparison of the results of latent class analysis (LCA) and mixture Rasch model (MRM) analysis using data from the Trends in International Mathematics and Science Study -- 2011 (TIMSS-2011) with a focus on the 8th-grade mathematics section. The research study focuses on the comparison of LCA and MRM to determine if results…

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…

This study provides the results of a latent class analysis (LCA) using data from the Trends in International Mathematics and Science Study -- 2011 (TIMSS-2011) with a focus on the 8th grade mathematics section. The study presents the analysis of item data with Mplus 7.31 to determine if results obtained yielded distinct latent subgroups. The data…

This article exemplifies how assessment design might be grounded in theory, thereby helping to strengthen validity claims. Spanning work across multiple related projects, the article first briefly summarizes an assessment system model for the elementary and secondary levels. Next the article describes how cognitive-domain theory and principles are…

The aim was to develop a new instrument for measuring length of sleep as well as television and computer habits in school-age children. A questionnaire was constructed for use when children visit the school health care unit. Three aspects of the validity of the questionnaire were examined: its face validity, content validity, and construct…

This study presents a conceptual and evidentiary study pertaining to the micro and macro level factors influencing the achievement gap among migrant children from a cross-national standpoint. First, this study provides the most systematic investigation of the immigrant educational paradox theory, which asserts that on average, immigrants'…

There are four sources of large-scale self-report survey data on victim rates, cross-nationally. These are EU Kids Online, Global School Health Survey, Trends in International Mathematics and Science Study, and Health Behaviour of School-aged Children. There are some differences in methodology between these surveys, but all use pupil self-report…

In the development of the national economies, the economy education in school curricula has an important place, because students may not have received the necessary economic realities and requirements. For that reason, it is necessary to determine the perception of wants and needs of children. In this study, it was aimed to develop a scale for…

Geometry plays an important role in the school mathematics curriculum all around the world. Teaching of geometry varies a lot (Hoyls, Foxman, & Kuchemann, 2001). Many countries revise the objectives, the content, and the approaches to the geometry in school. Studies of the processes show that there are not common trends of these changes…

The purpose of this study was to examine the impact of dimensionality, common-item set format, and different scale linking methods on preserving equity property with mixed-format test equating. Item response theory (IRT) true-score equating (TSE) and IRT observed-score equating (OSE) methods were used under common-item nonequivalent groups design.…

Students' attitude towards science (SAS) is often a subject of investigation in science education research. Survey of rating scale is commonly used in the study of SAS. The present study illustrates how Rasch analysis can be used to provide psychometric information of SAS rating scales. The analyses were conducted on a 20-item SAS scale used in an…

Research has shown that emotions play a significant role in the learning process and academic achievement. However, the fact that measurement of emotions during or after instruction usually requires written responses on lengthy research instruments has been given as a reason why researchers have tended to avoid research on this topic in…

This technical report summarizes student-level analyses conducted with the SEL Skills Survey and the Student Climate Survey to determine if a single measure of students' SEL skill acquisition and perceptions of school climate is possible. A separate research brief of this report also was published. [This report was supported by St. David's…
