The current study explored students’ scientific epistemological beliefs in relation to socio-economic status (SES) and gender. Eight grade Turkish elementary school students participated in the study. The analysis indicated that students with a working mother and educated parents as well as greater number of books at home together with a separate study room are more likely to have tentative views and less likely to have fixed views about science compared to students with unemployed mother, uneducated parents, less books at home, and no separate study room.
