Abstract
This research aims to investigate the effect of cooperative learning model Course Review Horay (CRH) towards learning outcomes for chemisty subject matter of stoichiometric solution students in class X MIPA SMAN 1 Praya Tengah. Quasi experimental in the form of posttest only control group design is the type of this study. The population of this research was all students of X MIPA SMAN 1 Praya Tengah. Random sampling method was chosen to be the sampling method of this study. The sample of this study were X IPA 2 as the experiment class and X IPA 1 as control class. In experiment class, cooperative learning model Course Review Horay (CRH) was given, whereas conventional learning model was applied in control class. The result of statistic t-test to test the hypothesis at significant level (5%) showed that t count (2,291) > t table (1,671) which means H 0 is rejected. Based on this results, it can be concluded that the implementation of cooperative learning model Course Review Horay (CRH) provides better impact towards learning outcomes for chemistry subject matter of stoichiometric solution students in class X MIPA SMAN 1 Praya Tengah.
