There are three classes which were choiced as the research samples. Xb as the first experiment class (TPS), Xa as the second experiment class (TGT) and Xf as the control class. The three samples were tested for normality using the Liliefors test and for homogenity using the Bartlett test. The analyze of hypotesis is using t-test. Based on the result of data analysis, the cooperative learning models TPS and TGT can improve the student’s achievement (tobserved = 1,96 > ttable = 1,67 ; tobserved = 3,12 > ttable = 1,67). The are no significant differences between the aplication of the TPS and TGT models in improving the student’s achievement (tobserved = 1,78 < ttable = 2,00).Keywords : Comparison Study, Think Pair Square (TPS), Team Games Tournament (TGT), Student’s Achievement, Hydrocarbons.]]>
