Abstract

Problem solving skills are essential skill for students to live in a challenging world. Teachers are required to carry out the mathematics instruction that could train these skills. One of the learning models that can be used is problem based learning (PBL) with rich mathematical tasks. Therefore, the purpose of this study is to apply the PBL-based Rich Tasks model to develop students' problem solving skills. This study used one-shot case study experimental design involving 21 grade 9 students from one of the junior high schools in Banda Aceh. The results showed that PBL with Rich Mathematical Tasks was able to develop students' problem solving skills with an average achievement before treatment (pre-test) equal to 2.92 which then improve after treatments given with the score equal to 70.82. In addition, the score of each of the end lesson tests also risen with 62.14 for PB1 and 67.75 for PB2. This improvement was gained because the PBL with rich tasks approach has the potentials to facilitate student learning mathematics. Teachers are advised to use the PBL with rich tasks approach continuously in the daily mathematics instruction, so that students’ problem solving skills can be improved in the future.

Abstrak

Keterampilan pemecahan masalah merupakan skil penting yang harus dimiliki peserta didik agar dapat hidup bertahan dalam dunia yang penuh dengan tantangan. Untuk itu guru dituntut agar mampu melaksanakan proses pembelajaran matematika yang dapat melatih keterampilan tersebut. Salah satu model pembelajaran yang dapat digunakan adalah model belajar PBL berbasis Rich Tasks Matematika. Oleh karena itu tujuan penelitian ini adalah untuk menerapkan model PBL berbasis Rich Tasks untuk menumbuhkembangkan keterampilan pemecahan masalah siswa. Penelitian ini menggunakan desain eksperimen one-shot case study yang melibatkan 21 siswa kelas IX dari salah satu sekolah menengah pertama di Banda Aceh. Hasil penelitian menunjukkan bahwa PBL berbasis Rich Tasks mampu mengembangkan keterampilan pemecahan masalah siswa, dengan rata-rata nilai tes awal sebesar 2.92 yang meningkat pada tes akhir dengan nilai rata-rata sebesar 70.82. Begitu juga dengan nilai tes matematika di akhir setiap pertemuan terus meningkat yaitu 62,14 (P1) dan 67.75 (PB2). Hal ini disebabkan karena model PBL berbasis rich tasks sangat potensial dalam memfasilitasi siswa belajar. Guru disarankan untuk terus dapat menggunakan rich tasks secara kontinue dalam proses pembelajaran matematika sehari-hari, sehingga keterampilan pemecahan masalah siswa dapat ditingkatkan dimasa yang akan datang.
