This research is motivated by the low ability to solve mathematical problems in fifth grade students of SDN Kaliabang Tengah 1 Bekasi Utara. Seen when researchers provide exercises in the description of mathematical problems in the form of stories on fraction material. There is still a lack of student knowledge regarding fractional material. When working on the story problem students simply add up or subtract the denominator by the denominator and the numerator by the numerator, without first equating the denominator. Students have not been able to solve problems correctly and many are still wrong. The lack of students' ability to infer results obtained from mathematical story problems. Enthusiastic students are lacking in solving mathematical story problems that are considered difficult. This study aims to improve the ability to solve mathematical problems using problem solving models in fifth grade students at SDN Kaliabang Tengah 1, North Bekasi. The research method uses Classroom Action Research (CAR) which consists of 3 cycles.. The conclusion of this study is the problem solving model can improve the ability to solve mathematical problems in fifth grade students at SDN Kaliabang Tengah 1 Bekasi Utara.

This research is motivated by the lack of reasoning and problem-solving skills math class V students on the subject of the story about the multiplication and division of fractions. Students are less able to understand and decipher the core issues contained in the matter of the story. In addition, students difficulty changing story problems into mathematical form. This makes the learning achievements of students who achieved less than the maximum.Issues examined in this study were (1) Is the mathematical reasoning fifth grade students Karangayu SD N 02 Semarang can reach the learning criterion was after receiving RME? (2) Is there any difference in the ability to solve mathematical problems Karangayu fifth grade students of SDN 02 Semarang after receiving RME learning?This research is quantitative. By using the design / design study pre-experimental design types of one- group pre-test-post-test design. Based on the pre-test and post-test reasoning variables obtained average value of 51.38 in the pre-test criteria for low and average value of the post-test 65.06 on the criterion of moderate / normal. The research hypothesis has been mentioned that, H01 is rejected and thank Ha1 the mathematical reasoning fifth grade students Karangayu SD N 02 Semarang reach criterion medium / normal after getting learning RME (Realistic Mathematic Education). While the t-test on the variable math problem-solving skills obtained t count> t table = 5.971> 2.021. The research hypothesis has been mentioned that, H01 and thank Ha1 denied that there are differences in the ability to solve mathematical problems graders V SD N Karangayu 02 Semarang after getting learning RME.

Problem Solving Strategies

Mathematical reasoning is the ability to think about mathematical problems, namely by thinking logically about mathematical problems to get conclusions about problem solutions. There are several factors that can affect students' mathematical reasoning, including mathematical abilities. Dissimilarity of students' mathematical abilities allows for dissimilarity in their mathematical reasoning abilities. So, this research intends to describe students' mathematical reasoning abilities in solving social arithmetic problems based on dissimilarity in mathematical abilities. The purpose of this research was to describe qualitative data about the mathematical reasoning abilities of students with high, medium, or low abilities in solving social arithmetic problems. The instrument used was the Mathematical Ability Test to determine the three research subjects, followed by a Problem Solving Test to get qualitative data about students' mathematical reasoning abilities, then interviews to get deeper data that was not obtained through written tests. Thus, the research data were analyzed using mathematical reasoning indicators. From the result of data analysis, it was found that all students understood the problem well. Students with high and medium mathematical abilities are determining and implementing problem solving strategies properly, namely writing down the step for solving them correctly and making accurate conclusions by giving logical argumens at aech step of the solution. However, students with low mathematical abillities have difficulty in determining and implementing problem solving strategies because they do not understand the concept, thus writing the steps to solve the problems incorrectly and not giving accurate conclusions about the correctness of the solution.
