Abstract

Mathematics learning is very important given in order to the students can have problem-solving abilities. This study aims to test the effectiveness of cooperative problem solving (CoPS) learning assisted by the GeoGebra 3D on students' problem-solving abilities and describe problem solving abilities in terms of students' GeoGebra 3D usage. This research is a type of quantitative and qualitative. The study was conducted in a junior high school named SMP Islam Al Azhar 14 Semarang in the 2018/2019 academic year. The research subjects were eighth grade students consisting of one experimental class with cooperative problem solving learning assisted by GeoGebra 3D treatment and one control class. Then two students were selected for each of the high, medium, and low GeoGebra 3D usage categories. Hypothesis testing uses one-party proportion test and average difference test. The results of the study showed that cooperative problem solving (CoPS) learning assisted by GeoGebra 3D was effective on students' problem-solving abilities. Students with medium and high usage categories of GeoGebra 3D can reach all indicators of problem-solving even though several indicators of problem-solving are achieved with insignificant errors. Students with medium and high GeoGebra 3D usage categories can implement the steps of problem-solving according to Polya's steps, even they are as good at the carry out the plan step. Students with low GeoGebra 3D usage category cannot carry out the Polya's steps well. Students with low GeoGebra 3D usage category faced difficulties to devise problem-solving plan, carry out problem-solving plan, and looking-back step is not done.

Abstract

Tujuan penelitian ini adalah untuk mengetahui apakah kemampuan pemecahan masalah matematika siswa dengan pembelajaran kooperatif Think Pair Share (TPS) berbantuan worksheet dengan menyisipkan jeda strategis scrambled mencapai ketuntasan belajar dan untuk mengetahui apakah kemampuan pemecahan masalah siswa menggunakan pembelajaran kooperatif TPS berbantuan worksheet dengan menyisipkan jeda strategis scrambled lebih tinggi daripada prestasi belajar siswa menggunakan model pembelajaran ekspositori. Populasi penelitian ini adalah semua siswa kelas VII SMP N 22 Semarang tahun pelajaran 2012/2013. Dengan teknik cluster random sampling terpilih sampel siswa kelas VII-D sebagai kelas eksperimen dan kelas VII-E sebagai kelas kontrol. Data penelitian berupa data kemampuan pemecahan masalah dengan metode tes. Data tersebut diuji dengan uji proporsi dan uji t. Hasil penelitian menunjukkan kemampuan pemecahan masalah matematika siswa dengan pembelajaran kooperatif TPS berbantuan worksheet dengan menyisipkan jeda strategis scrambled mencapai ketuntasan belajar dan kemampuan pemecahan masalah siswa dengan pembelajaran kooperatif TPS berbantuan worksheet dengan menyisipkan jeda strategis scrambled lebih tinggi dari kemampuan pemecahan masalah siswa dengan pembelajaran ekspositori. Jadi, pembelajaran kooperatif TPS berbantuan worksheet dengan menyisipkan jeda strategis scrambled efektif terhadap kemampuan pemecahan masalah matematika siswa.
