Problem Solving Skills

Problem solving must be developed and internalized in mathematics<br />learning, so students have problem solving skills that students can<br />transfer to their daily lives when facing problems or difficulties.<br />There is a mental attitude that affects a person's success to become a<br />successful problem solver, namely adversity quotient. This mental<br />attitude affects the mindset and emotions so it is not easy to give up<br />in solving problems. This study aims to measure the relationship<br />between adversity quotient and problem solving abilities of junior<br />high school students in mathematics learning. This research is a<br />correlation study. The population was students of SMPN 1 Padang<br />Panjang 2014/2015 academic year, while 32 samples were selected<br />by purposive sampling. The data was collected using an adversity<br />quotient scale and a mathematical problem solving ability test. Data<br />were analyzed by regression correlation techniques. The results of<br />data analysis showed a correlation coefficient between adversity<br />quotient variables with mathematical problem solving abilities of r =<br />0.756&gt; rtable (0.297), meaning that there was a significant positive<br />relationship between adversity quotient and mathematical problem<br />solving abilities. The coefficient of determination obtained is r2 =<br />0.572 indicating that adversity quotient has an effect of 57.2% on<br />mathematical problem solving abilities of junior high school<br />students, while 42.8% is influenced by other factors

Tujuan penelitian ini adalah untuk meningkatkan kemampuan siswa SMA dalam pemecahan masalah dan komunikasi matematik melalui pendekatan problem posing dalam pembelajaran matematika. Metode penelitian yang digunakan adalah metode kuasi eksperimen. Populasi penelitian ini adalah siswa di salah satu SMA Negeri di Kabupaten Garut. Sampel penelitian dipilih secara acak berdasarkan kelas, sampelnya adalah kelas XII IPA 1 yang mendapat pembelajaran menggunakan pendekatan problem posing dan siswa kelas XII IPA 3 yang mendapat pembelajaran konvensional. Simpulan hasil penelitian ini adalah bahwa dalam pembelajaran matematika di SMA: 1. Kemampuan pemecahan masalah matematik siswa yang mendapatkan pendekatan problem posing lebih baik dibandingkan dengan konvensional, 2. Tidak terdapat perbedaan kemampuan komunikasi matematik antara siswa yang mendapatkan pendekatan problem posing dengan konvensional, 3. Tidak terdapat kaitan yang signifikan antara kemampuan pemecahan masalah matematik dengan kemampuan komunikasi matematik pada siswa yang mendapatkan pendekatan problem posing. The purpose of this research is to improve the ability of high school students in problem solving and communication of mathematics through problem posing approach to learning mathematics. The method used is a quasi-experimental method. The study population was one of the students in high schools in Garut. Samples were selected randomly based on the class, the sample is a class XII IPA 1 gets learning using problem posing approach and class XII IPA 3 students who received conventional learning. Conclusion The results of this study is that the study of mathematics in high school: 1. mathematical problem solving ability of students to get a better problem posing approach compared to conventional, 2. there is no difference in the ability of mathematical communication between students who received conventional approach to problem posing, 3. there was no significant association between mathematical problem solving skills with communication skills in students who get a mathematical problem posing approach.

The aim of this research is to find the difficulties of students in solving word problems in the three-variable linear equation systems subject. Before they took a mathematical problem-solving exam, the learners were given reinforcement of prerequisite knowledge of the intended subject. The problem-solving test indicators used in this study were taken from Polya's problem-solving steps consisting of (1) recognizing the question, (2) making a plan for problem-solving (developing a plan), (3) implementing the plan for problem-solving, and (4) looking back. The research method used in this study was a qualitative descriptive. The subject in this study was 15 students who were 10 th graders of senior high school. The data were obtained from a student performance who took mathematical problems solving test. The result obtained from this study can be seen from the number of students whose achievement indicators formulate a plan of 49.6%, achievement in completing plans 14.1%, and achievement in checking solutions 2.2%. However, the indicators of understanding the problem area in the good category, namely 80%. The result of this study showed that the students were only able to solve the word problems for understanding the problem (good category) and devising the plan steps (mediocre category), whereas they got difficulties in solving the word problems in carrying out the plan and looking back (low category).

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.
