Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan hasil belajar penjumlahan dan pengurangan pecahan menggunakan model kooperatif tipe Teams Games Tournamet (TGT) dengan Student Teams Achievement Divicion (STAD) di kelas V SD. Desain penelitian ini quasi eksperiment dengan bentuk nonequivalent control group design. Sampel dalam penelitian ini adalah kelas V SDN 56 Payakumbuh sebagai kelas TGT dan SDN 32 Payakumbuh sebagai kelas STAD. Hasil penelitian menunjukkan bahwa terdapat perbedaan hasil belajar matematika siswa dengan menggunakan model kooperatif tipe TGT dengan model kooperatif tipe STAD di Gugus III Kota Payakumbuh. Hal ini dibuktikan dengan hasil thitung 2.98 dan ttabel pada taraf signifikansi 0,05 sebesar 1,68595, sehingga thitung > ttabel.

Abstract

The purpose of this study is to describe students' mathematical problem-solving abilities when answering HOTS questions on the material scale. The research method is descriptive, qualitative, and quantitative. The subjects of this study were students, namely 32 students of SD Negeri 36 Payakumbuh who had been taught scale material. The data collected are the written responses of the students as well as the results of student interviews. Problem-solving ability is measured by referring to the indicators of the National Council of Teachers of Mathematics (NCTM). From the results of the written answer data analysis, the researcher determined 6 research subjects, namely, 2 subjects each belonging to the upper, middle, and lower groups. The results of this study indicate the ability of group problem solving to be able to understand the problem and choose the right, systematic strategy. Middle-class problem-solving ability is defined as the ability to understand the problem, select the best strategy, and not be methodical. Lower-class problem-solving ability: unable to understand the problem, unable to choose the right strategy, and not systematic in solving the problem.
