Variability is underemphasized in domains such as engineering. Statistics and data science education research offers a variety of frameworks for understanding variability, but new frameworks for domain applications are necessary. This study investigated the professional practices of working engineers to develop such a framework. The Neglected,…

The present research aims to examine whether the questions in the Program for the International Student Assessment (PISA) 2009 reading literacy instrument display differential item functioning (DIF) among the Turkish, French, and American samples based on univariate and multivariate matching techniques before and after the total score, which is…

Teacher autonomy positively impacts various profession-related variables, including professional self-efficacy, motivation, job satisfaction, organizational commitment, teacher success, and job performance. The development and adaptation of sound instruments will contribute to achieving a complete understanding of teachers' autonomous behavior and…

This study aimed to adapt Teacher Academic Optimism Scale--Secondary (TAOS-S) to Turkish culture. A total of 453 public school teachers in Turkey participated in the study. We examined the validity, reliability, and measurement invariance of the scale across school levels. The results indicated good internal consistency of the TAOS, suggesting a…

In this study, Kernel test equating methods were compared under NEAT and NEC designs. In NEAT design, Kernel post-stratification and chain equating methods taking into account optimal and large bandwidths were compared. In the NEC design, gender and/or computer/tablet use was considered as a covariate, and Kernel test equating methods were…

The aim of this study is to investigate the cross-cultural measurement invariance of the reading skills items of the PISA 2018 at test and item level. Another aim of the study is to determine the item bias for items that do not show cross-cultural measurement invariance in line with expert opinions. A survey model was used in the study. The study…

Studies that focus on measurement invariance are of significant importance in proving the validation of high-stake tests, and in order to provide fairness from the results of these exams for special needs students. The aim of this study is to examine the measurement invariance of the "Central Examination for Secondary Education…

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…

One of the important theories in education and psychology is Generalizability (G) Theory and various properties distinguish it from the other measurement theories. To better understand methodological trends of G theory, a thematic content analysis was conducted. This study analyzes the studies using generalizability theory in the field of…

The purpose of this research is to examine measurement invariance of collaborative problem solving skills measured by PISA 2015 Xandar subtest for Singapore, Norway, and Turkey. The research was conducted with 2990 participants' data obtained from Turkey (1032), Norway (923), and Singapore (1035) on PISA 2015 collaborative problem solving study.…

Applying a measurement instrument developed in a specific country to other countries raise a critical and important question of interest in especially cross-cultural studies. Confirmatory factor analysis (CFA) is the most preferred and used method to examine the cross-cultural applicability of measurement tools. Although CFA is a sophisticated…

This work is intended to develop a measuring tool for determining teacher perception of informal relationships. The pool of items created by researchers through a literature review has been presented with expert assessment of the validity of the content, face, and meaning, and a draft scale has been created by making necessary revisions to the…

This study aims to reveal the trends in the related field by examining the researches evaluating the measurement invariance in education and psychology between 2008-2019. Accordingly, 99 articles published in three journals that were selected using the purposive sampling method among the journals indexed on Social Sciences Citation Index (SSCI)…

Foreign language testing is a multi-dimensional phenomenon and obtaining objective and error-free scores on learners' language skills is often problematic. While assessing foreign language performance on high-stakes tests, using different testing approaches including Classical Test Theory (CTT), Generalizability Theory (GT) and/or Item Response…

When students present writing tasks that require higher order thinking skills to work, one of the most important problems is scoring these writing tasks objectively. The fact that raters give scores below or above their performance based on several environmental factors affects the consistency of the measurements. Inconsistencies in scoring…
