Özet:PISA is one of the international large-scale surveys to assess the level of knowledge and skills of the 15-year-old students. In PISA 2015, the main theme was scientific literacy. Correspondingly, this study aims to determine factors that might affect the degree of scientific literacy of the Turkish students. Elastic net regression, which is one of the shrinkage methods was used to select a subset of variables. Then, these variables were modelled by using backward elimination technique manually in multiple linear regression. Based on the analysis, the study revealed that test anxiety, environmental awareness, interest in broad topics in science, playing video games after school, mathematics literacy, reading literacy, and collaborative problem-solving skills were the factors that contributed most to the degree of scientific literacy.
