The instruments used in this study are the pretest-posttest sheet about students scientific literacy. The SAS stated effective if the posttest result for each domain of scientific literacy get percentage >75% with high or very high category The results showed that effectiveness includes scientific literacy test get high and very high category. From this research, the students scientific literacy has increased from pretest to posttest. The percentage of each domain of scientific literacy are Science Contex about 79,16%; Science Knowledge, Content knowledge about 75%, Procedural knowledge about 91,67%, Epistemic knowledge about 100%; Science Competence about 100%; and Science attitude about 100%.
