Tujuan dari penelitian ini adalah untuk menelaah pencapaian kemampuan pemecahan masalah matematik siswa SMP yang pembelajarannya menggunakan pendekatan open ended. Subjek  Penelitian  ini adalah seluruh siswa SMP kelas VIII yang ada di Kabupaten Bandung, sebagai sampelnya ialah salah satu sekolah yang ada di Kabupaten Bandung, kelas VIII A sebagai kelas eksperimen yang memperoleh perlakuan dengan pendekatan open ended dan kelas VIII B sebagai kelas kontrol yang mendapatkan perlakuan dengan pendekatan saintifik. Metode penelitian yang digunakan yaitu metode kuasi eksperimen dengan desain pretes and postes. Instrumen yang digunakan dalam penelitian ini berupa tes kemampuan pemecahan masalah matematik berjumlah 5 butir soal uraian. Data diperoleh dari hasil pretes dan postes kemudian diolah dengan menggunakan software microsoft excel. Hasil penelitian menunjukan bahwa pencapaian kemampuan pemecahan masalah matematik siswa yang pembelajarannya menggunakan pendekatan open ended lebih baik dibandingkan dengan yang pembelajarannya menggunakan pendekatan saintifik. Kata kunci: kemampuan pemecahan masalah, pendekatan open ended, pendekatan saintifik. ABSTRACT The aim of this study is to examine the achievement of mathematical problem-solving abilities of junior high school students whose learning uses the open-ended approach. The subjects of this study were all eighth-grade junior high school students in Bandung regency, the sample was one of the schools in Bandung regency, class VIII A as an experimental class that received treatment with an open-ended approach and class VIII B as a control class that received treatment with a scientific approach. The instrument used in this study was in the form of a test of mathematical problem-solving abilities totaling 5 items of description items. Data obtained from the results of the pretest and posttest are then processed using Microsoft Excel software. The results showed that the achievement of students' mathematical problem-solving abilities for learning using the open-ended approach was better than learning using the scientific approach. Keywords: problem solving abilities, open ended approach, scientific approach.

This study is a quasi-experimental research, which aims to examine the achievement and improvement of problem-solving skills of mathematics and the independence of junior high school students learning through a realistic approach. The population in this study is all students of class VIII SMPN 4 Subang. Samples were taken by random class, obtained two classes of class VIII H as the experimental class and VIII.F as control class. The instrument in this study is a set of mathematical problem-solving test and a set of learning independence scales. The study found that the achievement and improvement of students' mathematical problem-solving ability and the independence of student learning whose learning using realistic learning are better than that of learning using ordinary learning in terms of the initial ability level of students. There is an interaction of mathematical problem-solving abilities between students whose learning uses a realistic approach with a student's initial ability level. Meanwhile, there is no interaction between realistic learning with the level of initial ability of students in generating student self-reliance. Besides, there is no association between mathematical problem solving ability and student learning independence, both in class that use realistic and classroom learning using ordinary learning. The picture of student's performance during realistic learning is more active, it shows the involvement of students both individually and in collaboration with the group, so that it can improve the problem solving ability of mathematics as well as student's learning independence. The description of the students' difficulties in solving the problem of mathematical problem solving ability lies in the indicator about number 5 which is about making the mathematical model because of the lowest percentage indicator.

This study aimed to examine comprehensively the effect of the application of REACT learning models based on the Malay cultural context of Riau on students’ mathematical problem-solving abilities. The research was a quasi-experimental research with Pretest-post-test control group design. The sample of this study was all students of class VII SMP 12 Pekanbaru. The results of data analysis were: (1) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning; (2) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning in terms of aspects of student ability levels, (3) There was no interaction between the learning model and the level of students’ ability to the ability to solve mathematical problems; (4) There was a difference in the mathematical problem-solving ability of Pekanbaru junior high school students who learned to use the REACT learning model based on the Malay Malay cultural context in terms of aspects of student ability levels.
