The effectiveness of collaborative learning model with challenging task on students mathematical problem-solving skills

AbstrakRendahnya kemampuan pemecahan masalah matematika siswa menyebabkan siswa kurang mampu menyelesaikan soal yang bersifat non rutin dan siswa masih kurang mengembangkan ide dan kemampuan yang dimilikinya. Penelitian ini bertujuan untuk mengetahui kemampuan pemecahan masalah matematika siswa melalui model Problem Based Learning berdasarkan Kemampuan Awal Matematika (KAM) siswa. Metode penelitian yang digunakan adalah kualitatif. Hasil penelitian ini menunjukkan bahwa kemampuan pemecahan masalah matematika siswa melalui model Problem Based Learning menjadi lebih baik. Sampel dalam penelitian ini adalah siswa kelas VIII-7 SMP Negeri 12 Padang yang terdiri dari 32 orang. Siswa yang awalnya berkemampuan rendah meningkat menjadi siswa berkemampuan sedang dengan peningkatan sebesar 75 %. Siswa yang awalnya tergolong berkemampuan sedang meningkat menjadi siswa berkemampuan tinggi sebesar 26 %. Siswa sudah mampu 1) memahami masalah, 2) menyusun rencana penyelesaian, 3) melaksanakan penyelesaian, dan 4) mengecek kembali jawaban.

Problem Solving Skills

Difficulties of primary school students in solving mathematical problems that require problem solving or reasoning abilities indicate the existence of problems in the process of learning mathematics, because one of the purposes of learning mathematics in primary school is to develop the students’ mathematical problem-solving skills. As a solution to overcome the problems, this research aims at understanding how the implementation of the guided discovery learning model influences mathematical problem-solving skills. This research employs a quasi-experimental design by involving all fifth-grade students at one of primary schools in Tebo Regency, Jambi. The simple random sample was conducted to obtain class VB as experimental class, and class VA as control class. Based on the results of the final score, experiential class obtained an average score of 86.00, and control class obtained an average score of 76.93. The results of hypothesis test using t-test obtained tcount = 2,203 > ttable = 2,020, which indicated that H0 was rejected, and H1 was accepted. Therefore, the guided discovery learning model influenced the fifth-grade students’ mathematical problem-solving skills, thus it is recommended for teachers to be able to use the guided discovery learning model in the mathematics learning process.
