This research is motivated by the students 'mathematical problem solving ability is still low, because mathematics learning in the classroom is not built to hone problem solving skills and the student worksheets used do not help students in honing students' mathematical problem solving skills, so the writer applies Polya's learning strategy with the help of problem solving sheet on social arithmetic material. This study aims to describe the steps of implementing Polya's learning strategy with the help of problem solving sheets in solving mathematical problems in social arithmetic material and to test mathematical problem solving skills by applying Polya's learning strategies with the help of problem solving sheets is it better than not implementing learning strategies Polya. This research was conducted using a quasi experimental method, with a population of all students of class VII Junior High School 3 Cisauk, Indonesia. The sample was selected using purposive sampling technique, namely students of class VII-6 and grade VII-7. Collecting data on students' mathematical problem-solving abilities using the final test (posttest). The results showed that Polya's learning strategy with the help of problem solving sheets on social arithmetic material was implemented properly and in accordance with Polya's steps. Based on the statistical test, it shows that the mathematical problem solving ability of students whose learning applies Polya's learning strategy with the help of problem-solving sheets is better than students whose learning does not apply Polya's learning strategy on class VII social arithmetic material at SMP Negeri 3 Cisauk, Indonesia.

ABSTRAKPada umumnya kemandirian belajar dan kemampuan pemecahan masalah matematika siswa SMP masih rendah. Guru sebagai pelaksana kegiatan belajar mengajar, menjadi faktor utama yang menjadi penyebab masalah tersebut terjadi. Salah satu upaya yang dapat dilakukan guru adalah menciptakan suasana belajar yang cocok dengan jenis gaya belajar siswa (auditorial, visual, ataupun kinestetik), sehingga diharapkan tujuan pembelajaran dapat dicapai secara efektif. Penelitian ini dilakukan di SMP Negeri 2 Tarogong Kidul kelas IX pada tahun ajaran 2015-2016 semester ganjil. Metode penelitian yang digunakan berupa penelitian eksplanatif komparatif-asosatif. Dari hasil penelitian terungkap bahwa: 1) Tidak terdapat perbedaan kemampuan pemecahan masalah matematik, antar siswa ditinjau dari jenis gaya belajarnya. 2) Tidak terdapat perbedaan tingkat kemandirian belajar matematika antar siswa ditinjau dari gaya belajarnya. 3) Kemandirian belajar siswa mempengaruhi tingkat kemampuan pemecahan masalah matematis siswa. Dari hasil penelitian tersebut menunjukkan bahwa setiap siswa, baik yang mempunyai gaya belajar auditorial, visual, ataupun kinestetik mempunyai tingkat kemandirian belajar dan kemampuan pemecahan masalah matematik yang sama. Selain itu, diketahui pula bahwa semakin tinggi tingkat kemandirian belajar siswa, maka semakin tinggi pula kemampuan pemecahan masalah matematis siswa.ABSTRACTIn general, independent learning and problem solving ability mathematics junior high school students is still low. Teachers practice teaching and learning activities, the main factor that causes the problem from happening. One of the efforts that teachers can do is to create a learning environment that matches the kind of student learning styles (auditory, visual, or kinesthetic), so hopefully learning objectives can be achieved effectively. This research was conducted in Tarogong South Junior High School 2 class IX in odd semester of school year 2015-2016. The method used in the form of comparative research explanation-associative. From the results of the study revealed that: 1) There is no difference in mathematical problem solving skills, among students in terms of the type of learning style. 2) There is no difference in the level of independence of learning mathematics among students in terms of learning styles. 3) Independence of student learning affects the level of students' mathematical problem solving ability. From the results of these studies indicate that each student, both of which have auditory learning style, visual, or kinesthetic have this level of independent learning and problem solving skills the same mathematical. In addition, it is also known that the higher the level of independence of student learning, the higher the students' mathematical problem solving ability.

This research aims to describe the mathematical problem solving skills of junior high school students in relationship materials and functions with Polya strategy. The method used in research is a qualitative descriptive method. This research was conducted at SMP Negeri 35 Palembang with a class XI.6 research sample of 30 people. The research subjects were taken by 6 students, who were grouped into three categories, namely high, medium and low who were taken 2 people each from each category.. The data collection techniques in this study are tests, interviews and documentation. The results of the data obtained are then analyzed using data reduction analysis techniques, data presentation and verification. So the results of the study show that: 1) students who have high category problem solving skills are able to carry out all stages of problem solving, 2) students who have problem solving skills category are able to carry out the problem solving stages of the problem, but at the stage of carrying out planning and problem solving students make mistakes in operation and are not able to perform the stage of planning the answer correctly, 3) students who have low category problem solving skills are only able to carry out one stage that is understanding the problem and not being able to carry out the stage of planning the solving strategy planning and troubleshooting and re-examining the answers obtained correctly.

Salah satu pembelajaran untuk meningkatkan kemampuan pemecahan masalah matematis adalah pembelajaran berbasis masalah. Tujuan penelitian ini adalah untuk mengetahui peningkatan kemampuan pemecahan masalah matematis siswa sebagai akibat dari pembelajaran berbasis masalah. Penelitian ini adalah kuasi eksperimen yang menerapkan dua pembelajaran yaitu pembelajaran berbasis masalah dan pembelajaran konvensional. Populasi dalam penelitian ini adalah siswa di salah satu SMK di Kabupaten Garut. Pengambilan sampel dilakukan secara purposive sampling, dan diperoleh dua kelas sebagai sampel penelitian. Instrumen penelitian yang digunakan adalah tes kemampuan pemecahan masalah matematis. Berdasarkan hasil analisis tersebut diperoleh kesimpulan bahwa: (1) peningkatan kemampuan pemecahan masalah matematis siswa yang mendapat pembelajaran berbasis masalah lebih baik daripada siswa yang mendapat pembelajaran konvensional, (2) Kesalahan-kesalahan yang dilakukan oleh siswa ketika mengerjakan soal-soal yang berkaitan dengan kemampuan pemecahan masalah matematis adalah kesalahan karena kecerobohan atau kurang cermat, kesalahan mentransformasikan informasi, kesalahan keterampilan proses, dan kesalahan memahami soal.ABSTRACTThis research is motivated by the results of previous studies that showed that students' mathematical problem solving ability is not as expected. One lesson to improve mathematical problem solving is based learning problems .

Learning problem-solving skills emphasizes reasoning abilities to determine conclusions based on-premises, determining alternative solutions in decision making, thinking creatively in building alternatives to get keys, and critical thinking to evaluate the best solutions in answering problems. This study aims to identify biased publications using the trim and fill method in determining the effectiveness of learning on the problem-solving abilities of junior high school students. This research is a quantitative study with a meta-analysis approach. Data collection based on quantifiable variable numerical information analysis results from mathematical problem-solving abilities in two different learning groups. The data analysis technique uses bias publication analysis with the trim and fills method with the analysis procedure of calculating the effect size, heterogeneity test, calculating the summary effect using the random-effect model, and forest-plot analysis and biased publication analysis. The results showed no publication bias. The validity of differences in innovative and conventional learning effectiveness was valid on junior high school students' mathematics problem-solving skills. This shows that innovative learning effectively improves the mathematical problem-solving ability of junior high school students.
