In the experimental class the think pair share learning model was applied and the control class applied the conventional learning model. The results of the analysis of research data, obtained n-gain cognitive learning outcomes of the experimental class and the control class of 0.605 and 0.518 with the medium category. Based on the analysis of social skill questionnaire data, the n-gain of the social skills of the experimental class and control class was 0.669 and 0.541 with the medium category.
