The classes were chosen by using Random Sampling. The Design was Treatment by Block Design. The result of the study showed that: (1) The result of the study of the students who were taught by cooperative learning type Think Pair Share modelwas higher than the result those tought by conventional model. (2) The result study of male students who were taught by using cooperative learning model type Think Pair Share is higher than the those tought by conventional model. (3) The result study of female students who were taught by using cooperative type was higher than those tought by conventional model. (4) There was no interaction between the learning model with gender toward students result study.
