Abstract:. Problem solving is one of ways to develop higher order thinking skills. Strategy of problem solving that can be developed in mathematics learning is Polya's strategy. This study aims to analyze the problem solving difficulties of elementary school students based on Polya strategy. To support this research,descriptive analysis is used on seven elementary school students . The results show that, the difficulty of mathematical problems solving of elementary school students consist of the difficulty of understanding the problem, determining the mathematical formula/concepts that is used, making connections between mathematical concepts, and reviewing the correctness of answers with questions. These happened because the problem presented is in a story problem, that is rarely studied by the students. Students usually solve mathematical problems in a form of routine questions, which only require answers in a form of algorithmic calculations. Abstrak: Pemecahan masalah adalah salah satu cara dalam mengembangkan kemampuan berpikir tingkat tinggi. Salah satu strategi pemecahan masalah yang dapat dikembangkan pada pembelajaran matematik adalah strategi Polya. Penelitian ini bertujuan menganalisis kesulitan pemecahan masalah siswa sekolah dasar berdasarkan strategi Polya. Untuk mendukung penelitian ini digunakan analisis deskriptif pada tujuh orang siswa sekolah dasar. Hasilnya menunjukkan bahwa, kesulitan pemecahan masalah matematik siswa sekolah dasar meliputi, kesulitan memahami masalah, menentukan rumus/konsep matematik yang digunakan, membuat koneksi antar konsep matematika, dan melihat kembali kebenaran jawaban dengan soal. Hal tersebut disebabkan, masalah yang disajikan berupa soal cerita yang jarang dipelajari siswa. Siswa biasanya menyelesaikan masalah matematik berupa soal rutin, yang hanya menuntut jawaban berupa perhitungan algoritmik.

Education functions to upgrading, forming, character and develop civilization nation. Having the ability to think and actions to effective and creative in the realm of abstract and concrete can be used as self development independently. Students need to armed with critical thinking skills, systematic, logical, creative, and cooperate effectively to obtain, choose, and manage an information. Mathematics learning is directed to develop critical thinking skills and discussed open and objective because mathematics having strong and structure clear and links between the concept of the one with another concept. By analyzing learning needs of mathematics, formulate and designed a learning programs, choose a strategies and evaliated them correctly to get good results. The ability critical thinking is very important in studying new matter and that known way, and learn to ask effectively and reach a conclusion consistent with the facts. Mathematic learning with problem based learning is the concept of better used activity of the student during learning. In accordance with statements from Westwood (2008: 31) stated that PBL: 1) propel oneself directly in learning, 2) prepared students to critical thinking and analytical, 3) give opportunity to students to identify, find and use numerous this approuch in should think, 4) is the learning is very closely related to the real world and motivate students, 5) involving activeness in integrating information and skills of various the discipline, and 6) knowledge and strategy by the possibility of will be maintained and tranferred to the learning situation other, improve the ability to communicate and the social skills needed to cooperation and teamwork. By chance the learning process as an alternative in solving mathematical problems with using the ability critical think an to cultivate the scientific attitude of student.

This study aims to: 1) find out whether students' mathematical problem solving abilities that are taught with problem based learning are better than students who are taught by direct learning. 2) find out whether the mathematical problem solving ability of students who have high learning motivation is better than students who have low learning motivation. 3) find out whether there is an interaction between learning and student learning motivation towards students' mathematical problem solving abilities. This study uses a quasi-experimental method with a 2x2 factorial design. The study population was fifth grade students (five) in the odd semester of the 2017/2018 Academic Year at SDN 0407 Mondang which consisted of two classes with a sample of 50 students. The class used as the sample of the experimental group is class V A with 25 students and the control class is class V B with 25 students. Thus the sample selection is done by total sampling technique. Data was collected by student achievement test and student motivation instrument. The collected data was processed statistically using a two-way variance (anava) analysis technique with a significance level of 0.05. The results showed that (1) There was an influence of problem-based learning methods on the mathematical problem solving ability of Class V students of SD Negeri 0407 Mondang 2017/2018 Academic Year; (2) There is an influence of student learning motivation on the mathematical problem solving ability of fifth grade students of SD Negeri 0407 Mondang for the Academic Year 2017/2018; and (3) There is an interaction between problem-based learning methods and students' motivation to the mathematical problem solving ability of students of Class V of SD Negeri 0407 Mondang 2017/2018 Academic Year. Practically, this study recommends that teachers use problem-based learning methods in mathematics learning and pay attention to the level of student motivation so that the learning design is adjusted to that motivation level. Theoretically, this study contributes to adding knowledge related to problem-based mathematics learning in elementary schools. Further studies can deepen studies related to the suitability of student characteristics with the selected learning method because these aspects are indicated as one of the key factors for student learning success.
