GLOBAL WARMING AND ITS IMPACT ON THE ECOSYTEM USING THE ROLE PLAYING MODEL ON STUDENTS’ LEARNING OUTCOME IM GRADE VII JUNIOR HIGH SCHOOL STUDENTS

Abstract

Based on observations and interviews in SMP N 1 Rembang obtained information that students are less actively participate in the learning so they get low score. Starting from this, it is necessary to have a variety of interesting learning, innovative and make students active. One of learning model that can make students active is role playing learning model. This study aims to determine whether role playing learning model effect on learning result of theme of global warming and its effect on research ecosystem in grade VII and how many the effect is. The design of this research was a pretest-posttest control group design. Sample is class VII A (experimental class) and VII E (grade control) SMP N 1 Rembang. For the data collection, this research used documentation methods, test methods, observation method and questionnaire result. Influence of Role Playing Learning Model can be seen from the increase in pretest and posttest results with the classical N-gain was 0.695 (medium category). The result of its effect as measured by the correlation biseria (rb) is 0.695 (strong category) and the coefficient of determination (KD) is 48.34%. The average score of affective is 91.7% of experimen class, while control class is 88%. The average score of psychomotor experiment class is 89,8% and 88,3% of the control class. The overall results affective and psychomotor aspects score of experiment class is higher than control class. The result of student questionnaire respon towards learning process using role playing models is 31 students give a good response from 32 students. Conclusion on the research is model of role playing learning model of theme of global warming and its effects on ecosystem give positive effect on cognitive learning results is 48.34% and give positive effect in affective and psycomotor.
