In purpose of learning mathematics exist one aspect must be improved is mathematical problem solving ability. But in fact, a level of students’ ability in pertained to weak. A trigonometry is one of the material which is quite difficult understood students XI grade in SMA ISTIQOMAH Bandung. It is need to be held a solution in learning that is using Problem Based Learning (PBL). This research using the method classroom action research with two cycles, which each cycles has two meetings. At the end of each cycle, students are given a written test in the form of a description. The result of research, show an increase on the mathematical problem solving ability by applying PBL. Seen from the results of the average score on each cycle, pre-cycle results with a score 37, in cycle one the score becomes 69 (42,30%), and in cycle two the score becomes 77 (69,23%).

AbstractThis study aims to determine the increase in mathematical problem solving ability of students and student activities on the material fractions with metacognitive approach in class VII MTs Batang Toru. Subjek in this study were students of class VII MTs Batang Toru with many students of 30 people and the object of this study is improve the ability of mathematical problem solving and student activities through the application of metacognitive approach to the material fractions. After administration of the act of learning with metacognitive approach to problem solving ability test results on material obtained fractions in the first cycle of students who understand the problem 90% (very good), students are able to plan troubleshooting 66, 7% (bad), the students were able to solve the problem 63, 3% (bad), and the students were able to examine the returns of 56, 6% (very bad). The results of the study on the second cycle obtained by students who understand the problem 100% (very good), students are able to plan troubleshooting 86, 7% (good), the students were able to solve the problem of 83, 3% (good), and the students were able to re-examine 83, 3% (good) already meets the performance indicators. Conclusion The application of metacognitive approach can improve students' mathematical problem solving at a fraction of material in class VII MTs Batang Toru. Keywords : Classroom Action Research, Mathematical Problem Solving Ability Of Students,   Metacognitive Approach.

The Difference

AbstrakKemampuan pemecahan masalah merupakan bagian dari kurikulum pendidikan matematika saat ini. Fakta di lapangan menunjukkan bahwa kemampuan pemecahan masalah matematis siswa masih belum optimal, salah satu penyebabnya adalah masih banyak siswa yang menemui kesulitan dalam hal pemahaman konsep dasar. Mengoptimalkan kemampuan pemecahan masalah diantaranya dapat ditempuh melalui pembelajaran yang berpusat pada siswa. Model pembelajaran Learning Cycle 7E dan Problem Based Learning merupakan dua dari beragam model pembelajaran yang berpusat pada siswa. Adapun tujuan dari penelitian ini adalah untuk mengetahui perbedaan pencapaian kemampuan pemecahan masalah matematis antara siswa yang mendapatkan model pembelajaran Learning Cycle 7E dan Problem Based Learning. Hasil dari penelitian menyimpulkan bahwa tidak terdapat perbedaan peningkatan kemampuan pemecahan masalah matematis antara siswa yang mendapatkan model pembelajaran Learning Cycle 7E dan Problem Based Learning. Sementara itu, untuk kualitas peningkatan kemampuan pemecahan masalah matematis siswa yang mendapatkan model pembelajaran Learning Cycle 7E dan Problem Based Learning masing-masing berinterpretasi sedang namun skor perolehan nya berbeda. Secara umum, sikap siswa terhadap pembelajaran matematika menggunakan model pembelajaran Learning Cycle 7E dan Problem Based Learning masing-masing berinterpretasi baik. Abstract (Students’ Problem Solving Ability through Learning Cycle 7E and Problem Based Learning)Currently mathematical problem solving ability was a part of mathematics curriculum. In fact, the mathematical problem solving ability of students was not optimized, one of the reasons is there are still many students who have problems in terms of understanding the basic concepts. To optimizing the mathematical problem solving ability of students, it, can be reached by implementing student-centered learning. Learning Cycle 7E and Problem Based Learning are two of a lot of student-centered learning models. The purpose of this study was to determine the difference of achievement mathematical problem solving ability between students who get Learning Cycle 7E and Problem Based Learning models.  The results of this study are there is not a difference enhancement of mathematical problem solving ability between students who get Learning Cycle 7E and Problem Based Learning models. Meanwhile, the quality of enhancement mathematical problem solving ability students who get Learning Cycle 7E and Problem Based Learning models are in the middle interpretation. In general, students' attitudes toward learning mathematics using Learning Cycle 7E and Problem Based Learning models each in good interpretation.
