UPAYA MENINGKATKAN MINAT DAN PRESTASI BELAJAR MATEMATIKA MELALUI MODEL PEMBELAJARAN KOOPERATIF TIPE STUDENT TEAMS-ACHIEVEMENT DIVISION (STAD) SISWA KELAS VII B MTsN SIDOHARJO KULONPROGO

The purpose of the research to increase student interest and improve learning achievement of students in mathematics class VII B MTsN Sidoharjo Kulonprogo through cooperative learning model Student Team - Achievement Division (STAD). The research was Classroom Action research (CAR) conducted a minimum of two cycles . The subjects in this study class VII B MTsN Sidoharjo Kulonprogro totaling 21 students. Instrument in this study was the observation sheets, questionnaires interest in learning, and individual tests. The main data source in this study were students, teachers, and observations during the action learning in the classroom. The results indicate that the implementation of learning with cooperative learning model Student Team - Achievement Division (STAD) can improve student achievement class VII B MTsN Sidoharjo Kulonprogro. This is evidenced by the increase in the average value of 56.43 into 68.45 before the action in the first cycle and then on the second cycle increased to 75.07. Implementation of learning with cooperative learning model Student Teams - Achievement Division (STAD) can also increase students' interest in learning mathematics. This is evidenced by the increased percentage of each indicator that is the pleasure of a 65 % increased to 79 %, the concentration of learning from 76% to 82 %, the motivation to learn 65 % to 81 %, and interest or curiosity in mathematics from 64 % to 82 %. Suggestion of this research is for researchers who want to conduct similar research, plans should be more mature. And researchers should pay more attention to the maximum again in every student so that the expected interest and achievement can be increased to the maximum
