This study is a qualitative research by using the descriptive method that aims to examine the behaviour of eighteen students in Bandung, Indonesia. Six issues related to geometry were given to eighteen of second-grade junior high school students with heterogeneous abilities. The problems given to the students contained all of the problem-solving strategies such as guessing and checking, make a picture, make a list, make a table, working backwards, looking patterns, and using a logical reason, solving simple problems and making questions. Data collection was conducted through mathematical problem-solving tests, recording students’ presentations, and interviewing among researchers and students after doing the problems. The result of recording was a video during the presentation process, and the interview would explore their understanding of the given problems to see the behaviour used by subjects of the research. The data in this research showed that many students’ behaviour identified; in the relevant literature, there are terms of the behaviour of problem-solving naive, routine, and sophisticated. However, the category "naïve," "routine," and "sophisticated" did not fully draw various behaviours observed, it was obtained additional category termed behavioural problem solver "naïve," "routine," "semi-sophisticated" and "sophisticated". It was due to the category of regular students can be divided into two, some students can be directed, and some of them cannot be directed to sophisticated behaviour. Thus, the routine category can be classified into two categories: routine and semi-sophisticated.

This study is a quasi-experimental research, which aims to examine the achievement and improvement of problem-solving skills of mathematics and the independence of junior high school students learning through a realistic approach. The population in this study is all students of class VIII SMPN 4 Subang. Samples were taken by random class, obtained two classes of class VIII H as the experimental class and VIII.F as control class. The instrument in this study is a set of mathematical problem-solving test and a set of learning independence scales. The study found that the achievement and improvement of students' mathematical problem-solving ability and the independence of student learning whose learning using realistic learning are better than that of learning using ordinary learning in terms of the initial ability level of students. There is an interaction of mathematical problem-solving abilities between students whose learning uses a realistic approach with a student's initial ability level. Meanwhile, there is no interaction between realistic learning with the level of initial ability of students in generating student self-reliance. Besides, there is no association between mathematical problem solving ability and student learning independence, both in class that use realistic and classroom learning using ordinary learning. The picture of student's performance during realistic learning is more active, it shows the involvement of students both individually and in collaboration with the group, so that it can improve the problem solving ability of mathematics as well as student's learning independence. The description of the students' difficulties in solving the problem of mathematical problem solving ability lies in the indicator about number 5 which is about making the mathematical model because of the lowest percentage indicator.

Problem-solving ability is a characteristic of mathematical activities and a major ability in developing mathematical understanding. Mathematical problem-solving ability can be seen from several dimensions, one of which is cognitive style. Cognitive style is a unique way for each individual to acquire, process, store, use the information to respond to tasks or situations, and build knowledge. FD and FI cognitive styles are one type of cognitive style that are categorized by general ways of thinking, solving problems, learning, and dealing with other people so that they have a relationship with problem-solving abilities. The subjects in this study involved 72 students (around the age of 13-14 years), namely 33 students with FD cognitive style and 39 students with FI cognitive style. The problem-solving ability test instrument in this study was a mathematical problem-solving ability test that had been validated by experts and tested for reliability. The cognitive style test instrument is the Group Embedded Figure Test (GEFT) item developed by Witkin. The problem-solving ability of junior high school students with FI cognitive style is better than FD students even though the difference is not much different.

This study aimed to examine comprehensively the effect of the application of REACT learning models based on the Malay cultural context of Riau on students’ mathematical problem-solving abilities. The research was a quasi-experimental research with Pretest-post-test control group design. The sample of this study was all students of class VII SMP 12 Pekanbaru. The results of data analysis were: (1) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning; (2) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning in terms of aspects of student ability levels, (3) There was no interaction between the learning model and the level of students’ ability to the ability to solve mathematical problems; (4) There was a difference in the mathematical problem-solving ability of Pekanbaru junior high school students who learned to use the REACT learning model based on the Malay Malay cultural context in terms of aspects of student ability levels.

Kemampuan pemecahan masalah matematis adalah salah satu kemampuan yang harus dikuasai oleh siswa agar mampu secara matematis memecahkan masalah sering dijumpai di kehidupan nyata. Indikator kemampuan pemecahan masalah matematis meliputi mampu memahami masalah, merencanakan strategi pemecahan masalah, melakukan strategi atau prosedur pemecahan masalah, dan memeriksa kebenaran jawaban atau hasil yang diperoleh. Penelitian ini bertujuan untuk mengetahui kemampuan pemecahan masalah matematis siswa SMP ditinjau dari Kemampuan Awal Matematik (KAM). Metode yang digunakan pada penelitian ini adalah deksriptif. Subjek penelitian yaitu siswa kelas VIII F SMP Angkasa Lanud Sulaiman yang berjumlah 30 orang. Instrumen yang digunakan dalam penelitian berupa tes soal uraian kemampuan pemecahan masalah matematis sebanyak 5 soal. Analisis data yang digunakan dalam penelitian ini adalah dengan mengelompokkan siswa berdasarkan hasil Penilaian Tengah Semester (PTS) sebagai kemampuan awal siswa. Siswa dibagi menjadi tiga kelompok, yaitu kelompok KAM atas, kelompok KAM menengah dan kelompok KAM bawah. Hasil penelitian menunjukkan bahwa siswa kesulitan mengerjakan soal nomor 5 dan baik siswa kelompok KAM atas, KAM menengah maupun KAM bawah, siswa kurang menguasai indikator ke-4 yaitu memeriksa kebenaran jawaban. Kata kunci: kemampuan awal matematika, kemampuan pemecahan masalah matematis.   ABSTRACT Mathematical problem solving ability is one of the abilities that must be mastered by students in order to be able to mathematically solve problems often found in real life. Indicators of mathematical problem solving capabilities include being able to understand problems, plan problem solving strategies, perform strategies or procedures for problem solving, and check the truth of answers or results obtained. This study aims to determine the mathematical problem solving abilities of junior high school students in terms of Early Mathematical Ability (KAM). The method used in this study is descriptive. The research subjects were class VIII F Space Junior High School Sulaiman Air Base which numbered 30 people. The instrument used in the study was a test of the questions about the mathematical problem solving abilities of 5 questions. Analysis of the data used in this study is to classify students based on the results of the Middle Semester Assessment (PTS) as students' initial abilities. Students are divided into three groups, namely the upper KAM group, the middle KAM group and the lower KAM group. The results showed that students had difficulty working on the number 5 questions and both the upper KAM group students, the middle KAM and the lower KAM students, students did not master the 4th indicator, namely checking the correctness of the answers. Keywords: initial mathematical abilities, mathematical problem solving abilities.
