This study examined group differences in online reading comprehension (ORC) using student data from the 2016 administration of the Progress in International Reading Literacy Study (ePIRLS). An explanatory item response modeling approach was used to explore the effects of item properties (i.e., item format, text complexity, and cognitive…

The aim of this study was to explore the differential relationships between students' science performance and their ICT availability, ICT use, and attitudes toward ICT based on the data from the Program for International Student Assessment (PISA) 2015 across the countries and regions including South/ Latin America, Europe, and Asia and Pacific.…

The few studies on the achievement differences of mainstream and immigrant primary school students in large-scale assessments point to an achievement gap in many subject areas, with immigrant students trailing mainstream students. A recurrent methodological problem of these studies is that the two student groups do not come from comparable…

We examined Differential Item Functioning (DIF) and the size of cross-cultural performance differences in the Programme for International Student Assessment (PISA) 2012 mathematics data before and after application of propensity score matching. The mathematics performance of Indonesian, Turkish, Australian, and Dutch students on released items was…

Lower reading and mathematics performance of Turkish immigrant students as compared to mainstream European students could reflect differential learning outcomes, differential socioeconomic backgrounds of the groups, differential mainstream language proficiency, and/or test bias. Using PISA reading and mathematics scores of these groups, we…

Turkish students on average had lower scores than OECD countries on mathematics, science, and reading at international assessment programs. As PISA measures the extent to which 15-year-old students are prepared to handle the challenges they may encounter in their future lives, and evaluates students' ability to reflect and to apply their knowledge…

This study makes an important contribution to an expanding body of international comparative studies by exploring factors predicting differences in science and mathematics achievement by students in Turkey and the Republic of Korea on the 2011 TIMSS assessment. While these countries are similar with regards to population size, cultural beliefs…

There are many studies that focus on factors affecting achievement. However, there is limited research that used student characteristics indices reported by the Programme for International Student Assessment (PISA). Therefore, this study investigated the predictive effects of student characteristics on mathematics performance of Turkish students.…

Large-scale studies, such as the Trends in International Mathematics and Science Study (TIMSS), provide data to understand cross-national differences and similarities. In this study, we aimed to identify factors predicting mathematics achievement of Turkish students by comparing to Australian students. First, construct equivalence and item bias…
