This research type is a quasy experiment, with non-equivalent control group design. The subject of research is junior high school class 8. Sampling technique in this study is cluster random sampling that is random sampling conducted if the population is homogeneous and normally distributed. This research was conducted at SMPN 11 Yogyakarta. Research data were obtained by using research instrument that is pretest-posttest in the form of description and observation sheet of science literacy competency aspect. The question instrument that has been empirically tested has a reliability level of 0.644. Data analysis technique in this research is statistical parametric. The result of the research shows that there is a significant difference in scientific literacy between before and after student learning with NOS within guided inquiry approach in science learning by test-independent sample t-test with sig value. (2 tailed) of 0,000.
