The FATIH project was the largest K-12 level ed-tech integration project in Turkey. Its aim was to enhance the quality of education by improving technology in classrooms. To determine the outcome of the project a systematic literature review was carried out and the perspectives of in-service teachers were considered. The literature was searched…

Previous researchers have identified socioeconomic status as a significant predictor of achievement/literacy. However, it is important to recognize that the influence of socioeconomic status on literacy may vary at different levels of socioeconomic status. Thus, this study analyzes the relationship between socioeconomic status and literacy scores…

This study aimed to evaluate the item model fit by equating the forms of the PISA 2018 mathematics subtest with concurrent common items equating in samples from Türkiye, the UK, and Italy. The answers given in mathematics subtest Forms 2, 8, and 12 were used in this context. Analyzes were performed using the Dichotomous Rasch Model in the WINSTEPS…

The purpose of this research is to determine whether PISA 2018 mathematical literacy test items show a differential item functioning across countries. For this purpose, only the items in booklet number three were examined using the MIMIC method with Latent Class Analysis (LCA) approach. PISA 2018 tests are mostly developed in English. Therefore,…

The purpose of this study is to examine the effect of missing data imputation methods, namely regression imputation (RI), multiple imputation (MI) and k-nearest neighbor (kNN) on differential item functioning (DIF). In this regard, the datasets used in the research were created by deleting some of the data via the missing completely at random…

Bayesian Networks (BNs) are probabilistic graphical statistical models that have been widely used in many fields over the last decade. This method, which can also be used for educational data mining (EDM) purposes, is a fairly new method in education literature. This study models students' science success using the BN approach. Science is one of…

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 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…

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…

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…

In the 21st century, international interaction in social, economic, cultural, and educational fields has increased. Consequently, international standards have become essential in national education policies, reforms, and practices. As an international assessment, PISA has started to function as a prominent tool in this regard. However, the impact…

Students' out-of-school learning environment is one of the most prominent factors affecting their school success, which is mostly a source of inequity unfavoring disadvantaged groups. In some countries including Turkey, bilingual students are among disadvantaged groups because most of them are from immigrant families with low socioeconomic status.…

This study examines the factors affecting the mathematics achievement of 8th-grade students in Türkiye using data from the TIMSS in 2011, 2015, and 2019. The data were analysed with multilevel (two-level) modelling. The first level was the student, and the second level was the school. At the student level, such affective characteristics as…

"Introduction:" In this study, it was aimed to examine the relationships between the variables that related the reading skills of the students and the variables related to the opportunities that the student, family, and the school have. Variables related to students' reading skills (reading skills scores/PV1READ, perception of competence…

This study aimed to examine the achievements of 2019 Turkish Language Curriculum regarding main idea teaching in terms of PISA 2018 Reading Skills Test. In this regard, the overlap of the achievements in 2019 Turkish Language Curriculum in Turkey and the proficiency levels in PISA 2018 Reading Test were examined in the context of main idea…
