摘要：The aims of this study are to know the increasing of students’ achievement and to improve students’ achievement on polynomial by using cooperative learning type Jigsaw in Indonesia. The type of this research was a Classroom Action Research . The research was conducted in the second grade, State Senior High School of Kisaran, Indonesia which consist of 32 students and objects in this study was increasing of students’ achievement in polynomial by using the jigsaw method. The data was taken from the test of students’ achievement and observation. The form of Achievement test was essay test and it conducted in the end of cycle. The goals of observation to see the ability of researchers in the learning management in the learning process. The results of observation showed that there was increasing of students’ achievement. The average of student’s achievement in initial formative was 55.78 where there are 21 students who can not achieve the mastery learning or approximately 65.63% of the 32 students. On achievement test I, there was increasing in average student’s achievement to be 67.56 where there are 9 people who can not achieve the mastery learning or approximately 58.12% of the 32 students. On achievement test II, there was increasing average of student’s achievement to be 80.09 where there are 4 students who did not complete. This means that there are 87.5% of students who achieved mastery learning. Then we can conclude that the increasing of students’ achievement is enough significant. Based on the observation of each meeting, the ability of researchers are quite good at classroom management by implementing cooperative learning model jigsaw. Because of that, it suggests to mathematics teacher in order to use cooperative learning type Jigsaw in learning process as an alternative learning to improve students' achievement.
