The effectiveness of cooperative learning model with peer assisted tutors method complementation with student activity sheet on the students grade X SMAN 13 Semarang

The purpose of this research is to know the effectiveness of cooperative learning model with peer assisted tutorial method complementation with student activity sheet on work and energy material of student grade X SMAN 13 Semarang. The research design was used post-test only control group design. The sample determination method was used the random Sampling technique, which is to determine the control and the experimental class. Indicators of effectiveness in this study are interest, activities and cognitive learning outcomes of students of experimental class higher than the control class. Based on the data analysis, it is found that in the experimental class, students who are taught by cooperative learning model with peer assisted tutor's method have higher interest, activity and cognitive learning outcomes compared to the control class. For example, in the interest of students on the physics learning, in the experimental class the percentage of students who are very interested and enough interest to learn the physics on work and energy material are 18.9% and 81.1%, respectively, while the control class is 16.2% and 75.65%, respectively. Meanwhile, in the experiment class, there were no students who were not interested in physics learning when applied cooperative learning model with peer-assisted tutors, while in the control class taught by lecture method and information discussion there were 8.1% of students who were less interested in learning. Thus, it can be concluded that the application of cooperative learning model with peer assisted tutorial method complementation student activity sheet on work and energy material is quite effective.
