he background of this study is the low learning outcomes of English students. Of the 22 students only 9 studentsreached KKM. On this basis researchers do research by applying cooperative learning model type NHT toimprove English learning outcomes. This research is a classroom action research conducted in SMPN 1 Inuman,the subject of this study is the students of class VII with the number of 22 students. The results suggest that thelearning outcomes of English have increased in each cycle. This is evidenced by: In the basic score of thenumber of students who reached KKM or complete is 9 students (40.90%), the UH I has increased with thenumber of 17 students (77.27%) and in UH II increased with the number of 20 students (90.90%). In the basicscore of the learning result of the students get the value of 51,25 with the low category, at UH I experiencing theincrease of learning result with the acquisition value of 65,76 with the medium category, and at UH II studentlearning result again increase with the acquisition value equal to 79,25 with high category.

Abstract: The problem in this study is the lack of student activeness in learning causes low learning outcome percentage 52,94%. The form of research I use is classroom action research (PTK). Data were collected through observation, questionnaires, interviews, and test sheets, and the research phase was conducted in 2 cycles. The result of the research shows that the study of cooperative type listening team in the implementation of cycle 1 turns out that the students have not maximized their opinions so that the achievement of the value has not been maximized. It is seen from the students' learning result in cycle 1, the highest score is 80, the lowest score is 50, average 66 and the percentage of mastery of 58.82%. However, in cycle 2 students have been able to express the answers in groups well, and in cycle 2 ended the teacher's efforts to improve the learning outcomes with the highest score of students obtained by 90, with an average of 76, and the percentage of mastery of 94.11%. To improve student learning outcomes, teachers use the appropriate learning model and in accordance with the material that is taught, and critical thinking patterns and responsiveness of students can be honed by expressing opinions in front of the class.Keyword: Cooperative Learning Model Type Listening Team Improves Learning OutcomesAbstrak: Masalah dalam penelitian ini adalah kurangnya keaktifan siswa dalam belajar menyebabkan hasil belajar yang rendah persentasenya 52,94%. Bentuk penelitian yang saya gunakan adalah penelitian tindakan kelas (PTK). Data dikumpulkan melalui  observasi, angket, wawancara, dan lembar tes, serta tahap penelitian ini dilakukan dalam 2 siklus. Hasil penelitian menunjukan pengkajian terhadap hasil belajar menggunakan cooperative tipe listening team dalam pelaksanaan siklus 1 ternyata siswa belum maksimal  mengemukakan pendapat sehinga menyebabkan pencapaian nilai belum maksimal hal tersebut dilihat dari hasil belajar siswa pada siklus 1, nilai tertinggi 80, nilai terendah 50, nilai rata-rata 66 serta persentase ketuntasan sebesar 58,82%. Namun pada siklus 2 siswa telah mampu mengungkapkan jawaban dalam kelompok dengan baik, dan pada siklus 2 berakhirlah upaya guru untuk meningkatkan hasil belajar dengan nilai tertinggi siswa di peroleh sebesar 90, dengan rata-rata 76, serta persentase ketuntasan sebesar 94,11%. Untuk meningkatkan hasil belajar siswa, guru menggunakan model pembelajaran yang tepat dan sesuai dengan materi yang di ajarkan, dan pola berpikir kritis dan tanggap dari siswa dapat diasah dengan mengemukakan pendapat didepan kelas.Kata kunci: Model Cooperative Learning Tipe Listening Team meningkatkan Hasil Belajar

This research aimed to investigate the implementation of cooperative learning model in the type of Think Pair Square (TPSq) in order to improve students’ achievement. The design of the research was a Classroom Action Research with the techniques of collecting the data were through the observation sheet of students’ learning activities and summative test. The subject of the research were the 1st grade students of SMPN 4 Bengkulu City academic year of 2018/2019 with total amount of students were 32 consist of 16 males and 16 females students. The research was conducted in three cycles from 7th September 2018 until 13 October 2018. The result of the research showed that the implementation of cooperative learning model type Think Pair Square improved students’ achievement in Mathematic. Students’ learning activities were improved by giving the students work sheet that contains a completion process so that facilitate students in working on the students work sheet, appreciating the student with applause after they delivered their opinion, and dividing students in heterogenous groups based on their academic skills. The improvement on students’ achievement can be seen from the increasing on the mean of students’ scores from first cycle to third cycle namely: 74.35; 79.91; 81.14 and the percentage of classical learning completeness from first cycle to third cycle is : 76.67%; 83.33%; 93.33%.

This study aims to determine the improvement of students’ mathematical understanding abilities in class VII-2 SMP St. Thomas 3 Medan by applying the cooperative learning model type STAD assisted by geoboard. The method used in this research is classroom action research (CAR). The subjects in this study were students of class VII-2 St. Thomas Private School 3 Medan in the 2018/2019 Academic Year consisting of 32 students, 18 men and 14 women. From the research results it can be seen that there is an increase in students in students’ understanding ability by applying the geoboard-assisted type STAD cooperative learning model as follows: In the students’ mathematical early comprehension ability test is still realatively low, namely classical completeness obtained by 18.75% with very low categories. The results of the first cicle students’ mathematical understanding test that is obtained classical completeness of 53.12% with the medium category The results of the second cycle mathematical understanding test students obtained classical completeness 0f 84.37% with a high category. It can be seen that there is an increase starting from the ability of initial understanding, the ability to understand mathematical cycle I and mathematical understanding ability ability cycle II. So it can be concluded that the increase in students mathematical understanding abilities through the Geoboard-assisted STAD cooperative learning model increased from cycle I to cycle II, amounting to 31.25%.

The purpose of this study is to improve the mathematical problem-solving ability of students in class VII-1 MTs Islamiyah Medan through the STAD type cooperative learning model. This research is a Class Action Research (CAR). The subjects of this study were 40 students of grade VII-1 MTs Islamiyah Medan. The object in this study is to improve students' mathematical problem-solving abilities through the STAD Type Cooperative learning model on the subject of rectangular flat shapes. This research instrument uses tests of mathematical problem-solving abilities, observation, and interviews. Based on the preliminary results of the interviews conducted with the mathematics teacher, it was obtained that the mathematical problem-solving ability of students in class VII-1 MTs Islamiyah Medan was still not optimal. From the data obtained only 17.5% of students met the mathematical problem-solving ability criteria. This research was conducted in two cycles by providing treatment using STAD learning. Based on the results of data analysis students' mathematical problem-solving abilities in the first cycle obtained that 70% of students meet the criteria. But because it has not reached 85% completeness then continued with the second cycle. In the second cycle, 90% of students who met the criteria of mathematical problem-solving ability were obtained. The conclusion of this study is an increase in students' mathematical problem-solving abilities from cycle I to cycle II.
