AbstrakKemampuan problem solving dan problem posing matematis merupakan kemampuan matematis yang perlu dimiliki oleh mahasiswa. Melalui kedua kemampuan ini, seorang mahasiswa dapat lebih kreatif dalam mengungkapkan ide serta gagasannya dengan cara menghubungkan pengetahuan yang dia peroleh sebelumnya dan mengaitkannya dengan pengetahuan yang dia diperoleh sekarang; serta mampu menuangkan gagasan/ide dalam menyelesaikan persoalan matematis yang dihadapinya. Namun pada kenyataannya, masih banyak mahasiswa yang belum memiliki kedua kemampuan ini, sehingga perlu diadakan perbaikan pembelajaran melalui pendekatan yang tepat. Pada penelitian ini, pendekatan pembelajaran yang dijadikan sebagai solusinya adalah pendekatan Realistic. Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan problem solving dan problem posing matematik mahasiswa melalui pendekatan Realistic. Metode penelitian yang digunakan pada penelitian ini adalah metode kuantitatif. Instrumen yang digunakan pada penelitian ini berupa tes diagnostik berupa pre-test dan pos-test, dan angket. Hasil dari penelitian ini, kemampuan problem solving dan problem posing mahasiswa cenderung meningkat. Rekomendasi bagi peneliti lain adalah melakukan penelitian sejenis ini dengan subjek penelitian yang berbeda, seperti mahasiswa calon guru.AbstractMathematical problem solving and problem posing skill are the mathematical skills that need to be owned by students. By having this skill, students can be more creative in expressing ideas by connecting the knowledge that they held previously. But in reality, there are some students who are lack of problem solving skill; therefore it is really important to improve learning through appropriate approach. Realistic approach had been chosen as the learning theory to be applied in the class. This study has the objective to find out whether the use of realistic approach enhances students’ mathematical problem solving and problem posing skills. The research methodology used in this study is a quantitative research. The instrument used diagnostic tests (pre-test and post-test); and questioner. The results of this study, the mathematical problem solving and problem posing skills students tend to increase. Recommendations for other researchers are do the research of mathematical problem solving and problem posing skills in other populations, especially prospective teachers.

Mathematical problem solving is a problem solving that uses mathematical problem solving. Students in the problem solving did not use the polya method so that students succeeded in difficulties. Educators still use conventional learning models so that students become bored, passive and reluctant to ask whether going forward working on the questions given by the educator, so that new learning models need to be applied. The e-learning learning model assisted with Edmodo learning media is an online presentation material on an Edmodo account using the mobile phone of students. PAM is the knowledge learned by students before getting learning material. This study aims to study the interaction of e-learning learning models assisted by Edmodo learning media to solve mathematical problems. This study is quantitative research. Data collection used with tests, interviews, collection and collection. The data analysis technique uses two-way anava test with cells that are not the same. From the results of the analysis, the influence of the e-learning learning model on mathematical problem solving abilities. It is necessary to question the high, medium, and low mathematical initial knowledge of Great mathematical problem solving ability, then there is no difference between assisted e-learning learning models edmodo, mathematical initial knowledge of mathematical problem solving abilities.

This study is a quasi-experimental research using factorial design. This study aimed at finding the facts that had been resulted from the different influence caused by the use of Open-Ended method and that of STAD method on the students’ mathematical problem-solving skills in terms of learning achievement. The learning achievement was categorized into two types namely the high achievement and the low achievement. The population in this study was Grade V students from SD Negeri Serayu. The data were analyzed by ANAVA univariate test. The results of the study were as follows. First, there have been differences in the mathematical problem-solving skills of the students who had been taught using Open-Ended method and those who had been taught using the STAD method. Second, there were also differences on the students’ score. For the students who had been taught using the Open-Ended method, the highest posttest average score of their learning achievement was 95.71 while the lowest post-test average score of their learning achievement was 63.92. These students’ total average score of learning achievement was 81.04. On the other hand, for the students who had been taught using STAD the highest posttest average score of their learning achievement was 95.50 while the lowest posttest average score of their learning achievement was 70.00. These students’ total average score of learning achievement was 89.13. Third, there has not been any differences between the Open-Ended method and the STAD method.

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.
