ABSTRAKPenelitian ini dilatarbelakangi oleh hasil-hasil penelitian terdahulu yang menunjukkan bahwa kemampuan pemecahan masalah matematis siswa belum sesuai dengan yang diharapkan. Salah satu pembelajaran untuk meningkatkan kemampuan pemecahan masalah matematis adalah pembelajaran berbasis masalah. Tujuan penelitian ini adalah untuk mengetahui peningkatan kemampuan pemecahan masalah matematis siswa sebagai akibat dari pembelajaran berbasis masalah. Penelitian ini adalah kuasi eksperimen yang menerapkan dua pembelajaran yaitu pembelajaran berbasis masalah dan pembelajaran konvensional. Populasi dalam penelitian ini adalah siswa di salah satu SMK di Kabupaten Garut. Pengambilan sampel dilakukan secara purposive sampling, dan diperoleh dua kelas sebagai sampel penelitian. Instrumen penelitian yang digunakan adalah tes kemampuan pemecahan masalah matematis. Berdasarkan hasil analisis tersebut diperoleh kesimpulan bahwa: (1) peningkatan kemampuan pemecahan masalah matematis siswa yang mendapat pembelajaran berbasis masalah lebih baik daripada siswa yang mendapat pembelajaran konvensional, (2) Kesalahan-kesalahan yang dilakukan oleh siswa ketika mengerjakan soal-soal yang berkaitan dengan kemampuan pemecahan masalah matematis adalah kesalahan karena kecerobohan atau kurang cermat, kesalahan mentransformasikan informasi, kesalahan keterampilan proses, dan kesalahan memahami soal.ABSTRACTThis research is motivated by the results of previous studies that showed that students' mathematical problem solving ability is not as expected. One lesson to improve mathematical problem solving is based learning problems . The purpose of this study was to determine the increase in students' mathematical problem solving ability as a result of problem-based learning. This study is a quasi-experimental study that applies two problem-based learning and conventional learning. The population in this study were students in one of the vocational schools in Garut. Sampling was done by purposive sampling, and obtained two classes as the study sample. The research instrument used was a test of mathematical problem solving abilities.

<p class="JRPMAbstractBodyEnglish">This study aims to examine the effectiveness of Problem Based Learning (PBL) assisted by QR code on students’ mathematical problem solving ability. This experimental research was carried out on students of the Elementary School Teacher Education Study ProgramUniversitas Muria Kudus in the mathematical concept course in the academic year of 2016/2017. The ability to solve mathematical problems is measured by tests. Data analysis techniques used include t-test and proportion test. The results of this study are: 1) the mathematical problem solving ability of students who learn through PBL assisted by QR code is better than the mathematical problem solving ability of students who learn through Direct Instruction learning; 2) the mathematical problem solving ability of students who are taught with PBL assisted by QR code have reached the minimum completeness criteria (MCC) and 3) the proportion of students taught with PBL assisted by QR code that has reached the MCC is better than the proportion of students studying through Direct Instruction learning that have met the minimum completeness criteria (MCC). Thus, the lecturer can develop PBL assisted by QR code to create interesting learning so that students are enthusiastic about the learning, which will have a positive effect on their mathematical problem solving ability.</p>

This research is a quasi-experimental study using one experimental group with the treatment of problem-based learning models combined with writing mathematics and a control group that is only given the treatment of problem-based learning models. Data collection methods consist of tests of mathematical problem solving abilities. Data analysis techniques using two path analysis of variance are not the sam cell. The results showed that the problem-solving ability of students who use problem-based learning models combined with writing mathematics is better than the problem-solving abilities of students who only use problem-based learning models in general or by the category of mathematical early ability. Judging from the early mathematical ability category, high and medium category students showed no significant difference in problem solving abilities while the problem solving ability of high and medium category students was better when compared to the problem solving ability of low category students. Keywords: problem based learning, writing mathematics, problem solving ability, mathematics early ability.

The purpose of this study was to analyze the mathematical problem-solving ability and characters of students who were taught using problem-based learning and ordinary learning based on Islamic perspectives. The instrument used in this study was a test of problem-solving ability and a students’ character questionnaire. This research was a quasi-experimental research with pre-test and post-test control group design. The sample of this research was 84 students from Private Islamic School in Medan, North Sumatera, by using a purposive sampling technique. The data in this research was declared homogenous and normal after being tested using the Levene’s Test and Kolmogorov-Smirnov Test. The hypothesis analyzes used was the Two Way-ANOVA test assisted by SPSS 25. The result showed that there was an improvement in mathematical problem-solving ability and students' characters through problem-based learning based on Islamic perspectives. However, there was no interaction between students' gender and problem-solving ability and character improvement based on Islamic perspectives. The gender factor in problem-based learning was not related to students’ cognitive and affective aspects. Each student with any gender had difference characters, especially related to Islamic perspectives. This research-proven that problem-based learning model had an important role in teaching and learning, and it can be used to improve students' mathematical and character problem-solving ability.

<p>This study aimed to examine the effectiveness of mobile blended compared to conventional problem-based learning on mathematical problem-solving skills and look for students' responses about the use of online learning. The study was conducted using a pretest-posttest quasi-experimental research design supported with descriptive qualitative responses involving 188 students taken by applying cluster random sampling as subjects of research distributed from vocational high schools in <em>Bojonegoro</em> City, East Java, Indonesia. Research findings revealed that mathematical problem-solving skills for students treated with mobile blended problem-based learning were higher than those who have been treated with purely problem-based learning. In addition, students have responded positively to the usage of mobile blended problem-based learning that was applicable and acceptable for effectively improving mathematical problem-solving skills.</p>
