This research is experimental research which aims to determine the effect of the advance organizer model on physics learning outcomes in terms of prior knowledge. This research uses a one group pretest-posttest design type . The sample in this research was class X MIA 1 SMAN 8 Mataram which consisted of 24 students. The data collection technique uses test sheets in the form of pre-test and post-test given before and after treatment. The pre-test data results were obtained with an average of 35.6 and 81.5 for the post-test average . The results of the prerequisite test with the Shapiro Wilk test showed that the pre-test and post-test data were normally distributed. Then, a t-test was carried out using a paired sample t-test showing a significant value (sig. 2 tailed) of 0.000, which means (sig. 2 tailed) < 0.005 so it can be concluded that there is an influence of the advance organizer learning model on physics learning outcomes in terms of priors knowledge.
