<![CDATA[Abstract: This research aims to find out the application of the Children Learning In Science (CLIS) learning model in class XII of SMA Negeri 1 Montasik, and to find out how much influence the Children Learning In Science (CLIS) learning model has on the learning outcomes of class XII students at SMA Negeri 1 Montasik. This research uses a quantitative approach with a type of Pre-experimental design research, in the form of one group pretest posttest design where there is only one group. The population in this study is all students in class XII which is 5 Class. The sample in this study is students in class XII.IPA3 which totals 33 Students. The sampling technique in this study uses Purposive sampling technique. The In data analysis techniques using tests Normality, homogeneity test, and t-test are two average differences.
