Based on a preliminary study at SDN Karangsono 1 that students had difficulty to solve problem-solving questions or questions presented in the form of stories, especially geometric material. The purpose of this study was to determine the ability to solve mathematical problems with the PBL model with the RME approach better than the PBL learning model. This study used a quantitative design with an experimental class and a control class. Data collection techniques used are tests and non-tes. The data analysis technique in this research is prerequisite test and hypothesis test. The results of this study were that the average mathematical solving ability of students using the PBL model with the RME approach is better than using the PBL model alone. This can be proved from the experimental class, the average indicator 1 during the pretest is 70 and when the posttest becomes 77, in indicator 2 during the pretest the average is 60 and becomes 73 during the posttest, in indicator 3 during the pretest the average is 50 and becomes 80 during the posttest, on the other hand in indicator 4 during the pretest the average is 53 and becomes 73 during the posttest. Meanwhile, in the control class in indicator 1 the average pretest was 50 and it became 65 during the posttest, in indicator 2 the average during the pretest was 60 and it became 70 during the posttest, in indicator 3 the average was 50 and it became 60 when posttest, and on indicator 4 the average is 55 to 60 during the posttest. This shows that students' mathematical problem-solving skills in the experimental class are better than those in the control class.

The cause of the lack of mathematical problemsolving ability of students in grade VIII.1 SMPN 16 Solok Selatan was because the learning model was still concentrated on the teacher. One effort that can be done to overcome this problem was to apply the PBL model. The objective of the study was to describe the process of improving students' mathematical problem-solving skills through learning with PBL model. The type of research was classroom action research. The study consisted of two cycles consisting of five meetings for each. The last meeting of each cycle was filled with the final test. This research consisted of four components, namely: action plan; action implementation; observation; and evaluation of the action (reflecting). The research was conducted on the students of class VIII.1 SMPN 16 Solok Selatan in the even semester of the academic year 2013/2014. Research subject amounted to 20 students. The collected data were analyzed descriptively. The result of this research indicated that there was an increase in problem-solving skills of mathematics students using the PBL model. The increase was seen from the increase of the average value of the final test cycle that examined the problem-solving and the percentage of mastery of student learning outcomes. It can be concluded that the PBL model can improve the problem-solving ability of students of grade VIII.1 SMPN 16 Solok Selatan in the even semester of the academic year 2013/2014.

Dalam belajar matematika dasar mahasiswa kurang aktif dan masih mengalami kesulitan dalam memecahkan masalah. Bahan ajar yang digunakan, pemecahan masalahnya belum berdasarkan kepada masalah nyata Oleh karena itu diperlukan bahan ajar berupa modul yang berbasis masalah dan meningkatkan kemampuan pemecahan masalah yaitu berbasis problem based learning (PBL). Tujuan Penelitian ini adalah mengembangkan modul berbasis PBL untuk meningkatkan kemampuan pemecahan masalah. Metode penelitian yang digunakan adalah penelitian pengembangan dengan tahapan: analisis, desain, pengembangan, implementasi, dan evaluasi. Hasil penelitian ini adalah: pada tahap analisis diperoleh hasil pentingnya mengembangkan modul berbasis PBL untuk meningkatkan pemecahan masalah. pada tahap desain, menyusun kerangka dan materi modul dengan langkah-langkah PBL yaitu: menyajikan, mendeskripsikan dan memecahkan masalah, menyajikan hasil dan kesimpulan, serta menyusun instrumen. Pada tahap pengembangan, produk dikembangkan dan diuji melalui validasi ahli, diperoleh hasil sebesar 82% (sangat valid). Tahap implementasi dilakukan uji coba kelompok kecil sebesar 87% (sangat praktis). Tahap evaluasi dilakukan untuk menilai produk, diperoleh hasil bahwa produk valid dan praktis digunakan serta dapat meningkatkan kemampuan pemecahan masalah sebesar 7,4 dalam kategori baik. Mahasiswa tertarik mempelajari modul dan terbantu dalam memecahkan masalah. Kesimpulannya adalah Modul Matematika Dasar berbasis PBL telah valid, praktis dan dapat meningkatkan kemampuan pemecahan masalah. Dalam penggunaan modul disarankan untuk memotivasi mahasiswa dan memberikan penjelasan materi dengan langkah-langkah PBL Kata kunci: modul Matematika Dasar, pemecahan masalah, problem based learning
