Mathematical problems are generally closely related to daily life. The problem is very important given to elementary school students because in general the story can be used to train students in solving problems. Solving stories can be used as a problem-solving strategy, although the question of mathematics is not necessarily a problem-solving question. The ability needed to solve the story problem is not only skill ability and maybe certain algorithm but also other ability that is ability to make plan and strategy that will be used in reaching completion. In addition, learning about the mixed story can also train the learners in their learning ability related to the three aspects of cognitive, affective, and psychomotor. Therefore, the ability of teachers as educators either personal or professional should take precedence. However, in reality, the teaching-learning process that is implemented tends to passively, where the concepts obtained by learners are still centered on the teacher. So it is necessary to find an alternative learning that can improve student learning outcomes. The constructivism approach is one of the proper approaches used in mathematics learning about mixed counts. Because, according to the expert view of constructivism, every learner has a role in determining what is learned. Emphasis is given to learners in order to form skills and knowledge by linking past experience with future use. Learners are not only given emphasis on facts or concepts but also given emphasis on the process of thinking and communication skills.

Quasi-experimental design was adopted in this study. Pretest-posttest, non- equivalent control group was used. Six intact classes, three of which were randomly assigned to experimental and the other three to control groups are used for the study. Sample of the study consisted of 284 SSII students from Enugu Education Zone. Two research questions and two hypotheses guided the study. Bearing Achievement Test (BAT) was used for data collection. BAT was constructed by the researcher and validated by three research experts. Mean and standard deviation were used to answer the research questions while the hypotheses were tested at .05 level of significance using Analysis of Covariance (ANCOVA). Experimental groups were taught using Polya‟s Problem Solving Strategy (PPSS) while control groups were taught the same topic using expository method. Major findings of the study revealed that students taught bearing with PPSS achieved higher than those taught with expository method. There was no significant difference between the mean achievement scores of male and female students in the study. It was recommended that Mathematics teachers should adopt PPSS for teaching Bearing and distances in senior secondary schools.

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.
