Since the onset of COVID-19 pandemic, there has been a significant rise in student absenteeism in the US and elsewhere. Meanwhile, food insecurity remains a persistent issue across the globe, including in the US. Food insecurity shapes students' immediate and wider contexts and may worsen school attendance. Applying ecological systems theory, we…

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…

The Programme for International Student Assessment (PISA) student questionnaire, despite being designed for low cognitive demand, may induce test burden due to its 306-item length, resulting in increased item nonresponse toward the questionnaire's end. Using the PISA 2018 response data from 80 countries and a cross-classified mixed effects model,…

A prior randomized trial found a school social intervention yielded significantly better outcomes (social and autism features) immediately following intervention compared to typical school programming (services-as-usual [SAU]) for children on the autism spectrum. In that study, children in the SAU condition subsequently completed a summer social…

The use of multistage adaptive testing (MST) has gradually increased in large-scale testing programs as MST achieves a balanced compromise between linear test design and item-level adaptive testing. MST works on the premise that each examinee gives their best effort when attempting the items, and their responses truly reflect what they know or can…

Previous research has indicated that attitudes influence various factors contributing to scientific achievement. Inadequate performance in science can limit career opportunities, underscoring the importance of comprehending how attitudes towards science can enhance overall scientific achievement. This study explored the mediating effect of…

Reading engagement is a strong predictor of students' reading outcomes, but its consistent positive effects across diverse student groups remain unclear. Research on the reading engagement of multilingual adolescents is notably limited. We investigated the interactions of affective and cognitive dimensions of reading engagement in relation to…

The purpose of this study was to evaluate the population invariance of equating functions across country subgroups in TIMSS 2015 mathematics tests in relation to the raw-score distribution, DIF, and DTF. We used equipercentile and IRT observed-score equating methods. The results of the study indicate that there is a relationship between the…

This study seeks to explore the effect of tools of school governance advanced by the global reform agenda (1) on student performance and (2) on reducing the effect of sociodemographic variables on this performance. To do so, we compare two Nordic welfare states with an egalitarian tradition: Sweden and Finland. The Swedish school system has…

The research aims to determine the factors affecting PISA 2018 reading skills using the Random Forest and MARS methods and to compare their prediction abilities. This study used the information from 5713 students, 2838 (49.7%) male and 2875 (50.3%) female, in the PISA 2018 Turkey. The analysis shows the MARS method performed better than the Random…

This study aims to evaluate mathematics curriculum used in social sciences high schools' preparatory classes based on Stufflebeam (CIPP) evaluation model in terms of context, input, process and product dimensions. With this aim, this study seeks to answer "How is preparatory class mathematics curriculum (PCMC) evaluated in terms of its…

Although scholars have proposed school climate as a key mediator through which school-based management (SBM) can improve educational outcomes, empirical evidence on the relationship between SBM and school climate improvement is sparse. In this article, we use three waves of Programme for International Student Assessment (PISA) data across 57…

The purpose of this study was to evaluate the distribution of students with varying levels of reading competence according to their selection of metacognitive methods from the 2018 Programme for International Student Assessment (PISA) survey. The research group consisted of 6,890 pupils from the Republic of Turkey who participated in the PISA 2018…
