The purpose of this study was to determine the differences in the improvement of students' mathematical problem-solving abilities with the Contextual Teaching and Learning approach in the material of the two-variable linear equation system in class X SMA Negeri 2 Pematangsiantar. This study used an experimental method with the aim of being in accordance with the previous statement to determine the difference in students' mathematical problem-solving abilities with a contextual approach and an expository approach, with a randomized pretest-posttest control group design. The average increase in problem-solving abilities in the control class was 0.1688 while the increase in problem-solving abilities in the experimental class was 0.0085. By using the t-test (SPSS), with a value of Fcount = 10.907 and a significant level of 0.05, a significant probability is obtained 0.002 <0.05, it can be concluded that there is a difference in normalized gain or an increase in problem-solving ability with conventional and contextual approaches. Based on the average gain of the control and experimental classes, the increase in the control class using the conventional approach is higher than the experimental class with the contextual approach. The difference in increasing problem-solving abilities in conventional classrooms is possible due to differences in students' entry-level abilities, which can be seen in the average pretest of each class.

Mathematical problem solving and critical thinking is two skills that need to be improved through learning mathematics. Metacognitive approach is one approach to improve them. This study aims to examine differences in the improvement of problem solving skills and mathematical critical thinking between students who get learning with a metacognitive approach and students who get conventional learning. This research is an experimental study with a pre-test post-test control group design research design. The population was all students of class XI of SMAN 3 Banda Aceh by taking samples of two classes, namely the experimental class and the control class through purposive sampling technique. Data collection was carried out using problem solving ability tests and mathematical critical thinking tests. Data analysis used t-test and analysis of variance. The results show that overall the improvement of students' mathematical problem solving and critical thinking skills that are learning with a metacognitive approach are better than students who obtain conventional learning, and there is an interaction between learning approaches and student ratings on mathematical problem-solving abilities

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.

This study aims to see how the efforts in improving the mathematical problem solving ability of high school students by learning STAD type cooperative strategies. This research is based on the importance of mathematical problem solving abilities that must be possessed by students, but the reality on the ground that these abilities are still very low. This research is an experiment with a pretest-posttest control group design. This is done in order to find out how much improvement in the ability to solve mathematical problems taught by learning mathematics in STAD type cooperative strategies. For the experimental group, students are taught with STAD type cooperative strategies, while in the control group, students are taught by direct learning. The population of this study was high school students, while the sample was students of class XI IPA of Laksamana Martadinata Medan Private High School. Five classes were randomly selected, class XI IPA 3 class as the experimental class and XI IPA 1 as the control class. The instrument used in the form of problem solving problems. Based on the results of the analysis, it can be concluded that: 1) there is a mean difference between students who are taught with STAD type cooperative strategies and those who are in direct learning. 2) Improvement of students' mathematical problem solving abilities that get cooperative learning type STAD gets direct learning ineffective.

This study is a pre test-post test experimental control group design having a goal to analyze  the role of contextual teaching and learning (CTL)  on students’ mathematical problem solving ability  (MPSA) and disposition (MD). The study involved 40  tenth grade students of a Madrasah Alyah (MA), a mathematical problem solving test, a mathematical  disposition scale. The study found that on MPSA, its gain, and on MD, students getting treatment with CTL attained better grades than grades of students taught by conventional teaching. Even if, both students’ grades on MPSA were still at very low level, on MD,  first group students’ grade on MD  was at medium level and the second group students’ grade was at low level.  Many students still realized difficulty on compiling MPSA. The other findings, there was no association between MPSA and MD, but students performed good perception toward CTL approach.

This research is motivated by the importance and still not optimal problem solving ability of student mathematical problem. This study examines the improvement of students 'mathematical problem-solving abilities that acquire Guided Inquiry learning with Concrete-Representational-Abstract approach (ITCRA) and students who have received conventional learning, in terms of overall and math skills categories KAM (high, middle, low). This research is a quasi experiment with non-equivalent control group design. The population is grade VIII SMPN 1 Padang Panjang Lesson Year 2014/2015, and the samples are two classes from seven existing classes. Instruments used in the form of tests, observation sheets, and interview guidelines. The data obtained were analyzed using the difference test, ie t-test and mann-whitney. The results showed that: 1) The achievement and improvement of mathematical problem solving ability of students who received ITCRA learning overall better than those who received conventional learning, 2) the increased mathematical problem solving ability of moderate KAM and low KAM better than those with conventional learning, whereas in high KAM, students who received ITCRA learning was no better than that of conventional learning, and 3) there was a difference in the improvement of students' mathematical problem solving abilities of high KAM categories with KAM moderate and low category students who received ITCRA learning. However, there were no significant differences between moderate and low KAM category studentsKeywords: Guided Inquiry, concrete-representational-abstact, problem solving
