Penelitian ini bertujuan untuk mendeskripsikan penerapan NHT-TGT dalam meningkatkan motivasi dan pemahaman konsep materi matematika SMA dari mahasiswa Kelas 2C Program Studi Pendidikan Matematika Universitas Islam Malang. Penelitian ini dilatarbelakangi oleh hasil studi pendahuluan yang kurang memuaskan. Skor motivasi mahasiswa tergolong dalam kriteria “sangat rendah” dengan skor 48,4. Hasil tes pemahaman konsep mahasiswa juga masih kurang memuaskan, hanya 22,6% mahasiswa “tuntas”, yaitu mahasiswa yang mendapatkan nilai Penelitian ini merupakan penelitian tindakan kelas yang dilaksanakan dalam 2 siklus dimana masing-masing siklus terdiri atas 4 pertemuan. Hasil dari siklus pertama menunjukkan persentase mahasiswa yang tuntas dalam pemahaman konsep mahasiswa meningkat menjadi 48,3%. Pada akhir siklus I, motivasi mahasiswa juga meningkat ke kategori “rendah” dengan skor 66. Selanjutnya, di siklus II motivasi kembali meningkat dan masuk kategori “tinggi” dengan skor 84,8. Demikian juga dengan persentase mahasiswa yang tuntas dalam pemahaman konsep meningkat menjadi 90,3%. Jadi penerapan NHT-TGT terbukti dapat meningkatkan pemahaman konsep dan motivasi mahasiswa.Kata Kunci: Number Head Together (NHT), Team Games Tournament (TGT), motivasi, pemahaman konsep, materi matematika SMA Implementation of NHT-TGT Learning Model to Improve Motivation and Conceptual Understanding of Mathematics for Senior High SchoolAbstractThe study aims to describe the application of NHT-TGT to improve students of Class 2C Mathematics Education Program University of Islam Malang’s motivation and understanding of high school mathematics material concept. The study is motivated by the results of preliminary studies were less than satisfactory. Student motivation score belonging to the criteria of "very low" with a score of 48.4. Student conceptual understanding test results are still unsatisfactory, only 22.6% of the students "completes", that is student scores ≥60. The study is a classroom action research which performed in 2 cycles with each cycle consisting of 4 meetings. The results of the first cycle show the percentage of students who complete the understanding of the concept increased to 48.3%. At the end of the first cycle, the students’ motivation also increased to the category of "low" with a score of 66. Furthermore, in the second cycle motivation score increased and categorized of "high" with a score of 84.8. Likewise, the percentage of students who complete the understanding of the concept increased to 90.3%.

Publisher : Program Studi Pendidikan Matematika Program Pascasarjan Universitas Negeri Yogyakarta

Tujuan penelitian ini adalah untuk: mendeskripsikan keefektifan pendekatan CTL setting NHT dan TGT; membandingkan keefektifan pendekatan CTL setting NHT dan pendekatan CTL setting TGT ditinjau dari prestasi belajar, kemampuan komunikasi matematis, dan sikap matematika siswa SMP kelas VII dalam belajar bangun datar. Penelitian ini merupakan penelitian eksperimen semu dengan desain pretest-posttest non-equivalent comparison-group design. Untuk mengetahui keefektifan pendekatan CTL setting NHT dan TGT pada masing-masing variabel, digunakan uji one sample t-test. Selanjutnya, untuk membandingkan keefektifan pendekatan CTL setting NHT dan TGT, data dianalisis menggunakan uji T2 Hotteling’s. Jika terdapat perbedaan keefektifan, maka dilakukan uji lanjut t-univariat. Hasil penelitian menunjukkan bahwa: pembelajaran matematika menggunakan pendekatan CTL setting NHT dan TGT efektif ditinjau dari prestasi belajar dan sikap matematika siswa, namun tidak efektif ditinjau dari kemampuan komunikasi matematis; tidak terdapat perbedaan keefektifan antara pembelajaran menggunakan pendekatan CTL setting NHT dan pembelajaran menggunakan pendekatan CTL setting TGT ditinjau dari prestasi belajar, kemampuan komunikasi matematis, dan sikap matematika siswa. Kata Kunci: pendekatan CTL setting NHT, pendekatan CTL setting TGT, prestasi belajar, kemampuan komunikasi matematis, sikap matematika siswa The Comparison of the Effectiveness of CTL Approach of NHT Type and CTL Approach of TGT Type in Learning Planes AbstractThis research aims to: describe the effectiveness of teaching mathematics by using the CTL approach of NHT type and the CTL approach of TGT type; compare the effectiveness of the CTL approach of NHT type and CTL approach of TGT type in terms of mathematics learning achievement, mathematical communication ability, and mathematics attitude of 7th grade junior high school students in learning planes. This research is a quasi-experimental research with the pretest-posttest non-equivalent comparison-group design. To determine the effectiveness of the CTL approach of NHT type and CTL approach of TGT type on each variable, one sample t-test was used. Furthermore, to compare the effectiveness of the CTL approach of NHT type and CTL approach of TGT type, the data were analyzed using a multivariate test of T2 Hotteling’s. If there were differences in effectiveness, then further study of t-univariate was done to determine certain variables that contributed to the overall difference. The results showed that: the teaching of mathematics using the CTL approach of NHT type and using the CTL approach of TGT type are effective in terms of mathematics learning achievement and mathematics attitude, but is not effective in terms of mathematical communication ability; there is no difference between the effectiveness of teaching using the CTL approach of NHT type and teaching using the CTL approach of TGT type in terms of mathematics learning achievement, mathematical communication ability, and mathematics attitude. Keywords: CTL approach of NHT type, CTL approach of TGT type, mathematics learning achievement, mathematical communication ability, mathematics attitudes of students.
