The focus of this study is to use the mixture item response theory (MixIRT) model while implementing the no-U-turn sampler as a technique for investigating the presence of latent classes (i.e., subpopulations) among eighth-grade students who were administered TIMSS 2019 mathematics subtest in paper format from the gulf cooperation council (GCC)…

Background: Teaching quality is assumed to be an essential prerequisite for student learning outcomes such as mathematics confidence and mathematics achievement. Notwithstanding its significance, empirical research examining the relations between teaching quality and learning outcomes is still limited, particularly among primary school students.…

Unfavorable test-taking behaviors, such as speededness and disengagement, have long been a validity concern for large-scale low-stakes assessments. Understanding the presence and extent of such behaviors is important for ensuring the validity of inferences based on test scores. This study examined test-taking behaviors using item response time…

Background: In recent years, data derived from international large-scale assessments have significantly influenced the discourse surrounding educational equity. However, the use of such data has often neglected the full spectrum of dimensions that equity encompasses, while being limited to exploring the relationship between achievement variations…

This paper extends existing work on teacher weighting in student-centered surveys by looking into aspects of practical implementation of deriving and using weights for teacher-centered analysis in the Trends in International Mathematics and Science Study (TIMSS) and the Progress in International Reading Literacy Study (PIRLS). The formal…

Background: Evaluations of effectiveness of educational reforms are often based on the level of improvement in student performance from one cycle of a particular assessment to the next. However, improvements in overall performance do not necessarily translate to improved equality. Indeed, improvements that favour certain subgroups of students can…

This study explored the influence of early literacy and numeracy skills on fourth-grade math achievement using the Trends in International Mathematics and Science Study (TIMSS). The study utilized valuable information collected by TIMSS about context related questionnaires such as home resources for learning, early literacy and numeracy…

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.…

In 2017, the mathematics assessments that are part of the National Assessment of Educational Progress (NAEP) program underwent a transformation shifting the administration from paper-and-pencil formats to digitally-based assessments (DBA). This shift introduced new interactive item types that bring rich process data and tremendous opportunities to…

Background: Socioeconomic characteristics are persistently and systematically related to academic outcomes, despite long-standing efforts to reduce educational inequality. Ireland has a strong policy focus on alleviating educational disadvantage and has seen significant improvements in mathematics and science performance in recent years. This…

In cognitive diagnosis assessment (CDA), the impact of misspecified item-attribute relations (or "Q-matrix") designed by subject-matter experts has been a great challenge to real-world applications. This study examined parameter estimation of the CDA with the expert-designed Q-matrix and two refined Q-matrices for international…

Large-scale international assessment studies such as Trends in International Mathematics and Science Study (TIMSS) or Programme for International Student Assessment (PISA) provide researchers and policy makers the opportunity to conduct secondary analyses to answer questions related to educational outcomes and compare the impact of certain inputs…

Socioeconomic status (SES) is considered a major predictor of student and school achievement. In most cases, SES is not malleable or available for manipulation to improve students' learning and achievement. Therefore, we explored other student and school-related factors that may be malleable to reduce achievement differences between students and…

Background: TIMSS 2019 is the first assessment in the TIMSS transition to a computer-based assessment system, called eTIMSS. The TIMSS 2019 Item Equivalence Study was conducted in advance of the field test in 2017 to examine the potential for mode effects on the psychometric behavior of the TIMSS mathematics and science trend items induced by the…

This study statistically investigates the characteristics of the intended curriculum for Japanese primary science, focusing on the learning content. The study used the TIMSS 2011 Grade 4 Curriculum Questionnaire data as a major source for the learning content prescribed at the national level. Confirmatory factor analysis was used to determine the…
