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.

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 research was motivated by the low mathematical problem-solving ability of the seventh grade students of Al-Falah Islamic Junior High School Jambi. This research is a quasi-experimental study with Nonequivalent Pretest-Posttest Control Group Design design and a pattern that is all students of Al-Falah Islamic Middle School in the academic year 2017/2018. Sampling used purposive sampling, which is a sample consisting of three classes namely class VII.1, VII.2 and VII.4 where the given sample is different. The instruments used in this study are teaching materials and mathematical solution ability tests. The research data were analyzed using non parametric Kruskal Wallis H. statistical results. The results showed that there were differences faced by students who studied with two types of Two Stay-Two Stray (TS-TS), Problem Based Learning (PBL) learning models, and models conventional learning. After further using the Games-Howell test, the differences in the TS-TS class and PBL class then become PBL classes and Conventional classes.Keywords: Mathematical problem solving ability, Two stay-Two Stray (TS-TS), Problem Based Learning (PBL).

Mathematical Problems

One of the main goals of school mathematics is the achievement of mathematical problem-solving abilities through problem-based learning. It is expected that these abilities can be achieved well by students. However, the complexity of the problem and minimum confidence become a problem when students experience complex situations created in the problem-based learning process. Scaffolding becomes essential because of the differences in each student's knowledge stored in long term memory. The purpose of the study was to analyze differences in mathematical problem-solving abilities with two different learning and based on initial mathematical abilities. Learning in the experimental class is problem-based learning with scaffolding, and then control class learning is problem-based without scaffolding. The research method used was a quasi-experimental design with a matching-only pretest-posttest control group design. Sample selection using purposive sampling to get samples with the same characteristics, the total number of samples is 60 students with each division 30. The initial mathematics ability has the same role in the mathematical problem-solving ability in the experimental and control classes. That is when students are in the high category then the ability of severe mathematical problem-solving. However, when the two classes are compared, the results are significantly different. Scaffolding becomes a factor that distinguishes the ability to solve mathematical problems.

This research is motivated by the low ability of students' mathematical problem solving. The purpose of research to determine the effect of Problem Based Learning (PBL) model of learning to improve students' mathematical problem solving abilities. This research was conducted at SMP Alijtihad II Kutabaru Tangerang Regency. The research method used is quasi experiment with design of non equivalent control group design. Sampling was done by using purposive sampling technique, student of class VIIIB as experiment class using PBL model and class VIIID students as control class with conventional method. The instrument used is a test to measure the ability to solve mathematical problems in the form of a description. Test instrument data were analyzed using the t-test and the Mann-Whitney U Test. Based on the result of calculation using t-test at 0.05 significance level, obtained tcount ≥ ttable (3,3841 ≥ 1,9966), so that PBL learning model can influence student's mathematical problem solving ability. The Mann-Whitney U Test showed that Zhitung ≥ Ztable (2.82 ≥ 1.92) thus enhanced mathematical problem-solving abilities in the class using the PBL model better than the conventional method. The improvement of students' highest mathematical problem solving abilities in the PBL class is on the indicators of planning the completion, whereas in the conventional class is on the indicators understand the problem

The Difference

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.
