Reading research in the United States has mainly focused on early or, less frequently, middle grades and on monolingual (MN or English-only) rather than on multilingual (ML) students. To address these gaps, we focused on factors contributing to high school ML students' reading achievement. In particular, we first used machine learning to identify…

This study analyzes how students' reported teaching practices of their teachers and their attitudes towards science are related to the science achievements of four high-performing countries/economies in PISA 2015: Hong Kong, China, Canada, and Finland. A study of these regions can shed light on the commonalities of and differences between the…

The purpose of this study is to analyze scientific literacy levels relevant to science and technology classes among gifted students that participate in scientific activities at science and art centers. This study investigated whether there was a significant difference in scientific literacy levels among gifted students according to the areas of…

This study aims to investigate the predictors of reading performance and how reading performance predicts mathematics and science performances in PISA 2018 study. For this purpose, the country in the focus (Turkey), the highest performer (China [B-S-J-Z]) in the world, and the lowest performer (Mexico) among the OECD members countries were…

The relationships among future-oriented motivation, self-efficacy, task values of science, and achievement outcomes were investigated among 15-year-olds across four Asian nations who participated in the Program for International Student Assessment (PISA) of the Organization for Economic Cooperation and Development (OECD). The factor structure of…

This paper reports how the context in which a mathematics item is embedded impacts on students' performance. The performance of Year 10 students on four PISA items was compared with performance on variants with more familiar contexts. Performance was not better when they solved items with more familiar contexts but there was some evidence that…

Since 2003, Turkey regularly participates in PISA. According to the PISA 2012 results, 15-year-old students in Turkey performed below both OECD countries and participating countries. Defining the relations between students' characteristics and their scientific literacy skills is thought to provide deeper understanding for the nature of this…
