EFFORTS TO IMPROVE STUDENT LEARNING OURCOMES BY USING COOPERATIVE LEARNING TYPE OF STUDENT TEAMS ACHIEVEMENT DIVISION (STAD)

Study the researchers did was an effort to improve student learning outcomes by using cooperative learning type Student Teams Achievement Divisions (STAD) that Classroom Action Research (CAR). This study aims to improving student learning outcomes after the use of learning model STAD. The subjects in this study were students of class VIII-H SMPN 1 Cianjur, which amounts to 46 people with a minimum completeness criteria of 70.00. Increased student learning outcomes are good, the first cycle of the average of 75.54 formative test increased to 76.09 in the second cycle, and than increased again in the third cycle becomes 79.46. While the formative test average of 77.03 for the third cycle and this can be seen also incr ease with the average cumulative test reached 80.54. The level of mastery learning students on the subject of geometry and geometrical measurements, the first cycles from 41 people increased to 43 people in the second cycle, and continued to increase in the third cycle to 46 people. So clasical increased absorption of the first cycles 59 % to 71.85 % in the second cycle, and became 78.91 % at the end of the third cycle or cycles obtained. The result show that Cooperative Learning type STAD, can be made as one solution to fix the future mathematics learning and improve student learning outcomes
