Low student learning outcomes are an important problem that needs to be solved in colloidal learning in high school. This research aims to find out the effectiveness of LKPD based science literacy on colloidal material. Quasi experiments using pretest-posttest control group design are applied as this research project. Students of grade XI IPA-2 as experimental class and XI IPA-1 as a control class with a total of 30 students being involved as samples of research conducted using total sampling techniques. Test instruments are developed to gather student learning data through pretest and posttest techniques. The effectiveness of LKPD was analyzed using the N-Gain test, independent sample t-test, effect size. The result of N-Gain obtained a rate score of 0.7319 with a high category for the experimental class whereas the control class received a score of 0.5308 with a sufficient category. Based on the results of this study, it can be concluded that LKPD based science literacy is effectively used in improving student learning outcomes on colloidal learning in high school.
