Penelitian ini adalah penelitian kualitatif deskriptif yang bertujuan untuk mendeskripsikan kemampuan pemecahan masalah siswa kelas XI SMA dalam menyelesaikan soal-soal pemecahan masalah matematika pada pokok bahasan lingkaran. Subjek dalam penelitian ini adalah 30 siswa di salah satu kelas XI IPA di SMA Negeri 5 Kota Bengkulu yang dipilih secara purposive sampling. Setelah siswa mengerjakan 5 soal pemecahan masalah tentang lingkaran selama 60 menit secara tertulis, jawaban siswa kemudian dianalisis dan diidentifikasi untuk menemukan bagaimana siswa menyelesaikan soal, banyak strategi pemecahan masalah yang digunakan siswa, serta banyak solusi atau jawaban yang didapat. Hasil penelitian menunjukkan bahwa beberapa siswa belum mampu menyelesaikan masalah dengan tepat disebabkan kesalahan dalam langkah mensintesis dan menganalisis soal. Strategi yang mayoritas digunakan oleh para siswa dalam menyelesaikan masalah adalah drawing a picture (menggambar). Siswa juga menggunakan strategi guessing and checking (menebak dan menguji). Berkaitan dengan banyaknya jawaban siswa, siswa menjawab soal tertutup dengan jawaban yang sama, sedangkan untuk soal terbuka ditemukan tiga jawaban berbeda.Students’ problem-solving ability in solving closed and open-ended problems on the subject of the circleAbstractThis research was descriptive qualitative research that aimed to describe the problem-solving abilities of eleventh-grade students in solving mathematical problems on the subject of the circle. The subjects in this study were 30 students in one of the XI Science classes in SMA Negeri 5 Bengkulu City, Indonesia selected by purposive sampling. After students worked on five problem-solving questions about the circle for 60 minutes in writing-form, the students’ answers were then analyzed and identified to find how students solve the problems, how many problem-solving strategies used by students as well as many solutions or answers obtained. The research finding showed that some students have been not able to solve the problems correctly due to their misconceptions when doing the steps of synthesizing and analyzing. The majority of the strategies used by students in solving problems were drawing a picture. Students also used the guessing and checking strategy. Regarding the number of students' answers found, students answered closed questions with the same answers while for open-ended questions, it was found that students were able to find three different answers.

International Student Assessment (PISA) is a system for measuring student’s ability in problem solving. The research aimed to determine the metacognition ability of class VIIA students in solving mathematical problems in the PISA model which include aspects of Planning, Monitoring, and Evaluation. This qualitative research was conducted in VII class of MTS Al-Kamil 2018/2019. The subjects in this study were 3 students of class VIIA who were selected by purposive sampling, namely 1 student with very good metacognition, 1 student with good metacognition, and 1 student with poor metacognition. Data collection techniques using tests in the form of PISA model questions, and metacognition questionnaires. The results showed that students with very good metacognition and students with good metacognition in solving problems with the PISA model were classified as moderate because students had not been able to maximize the aspects of metacognition abilities, however students with poor metacognition in completing PISA questions are classified as low because almost all aspects of metacognition are not considered well. Keywords: metacognition ability, problem solving, PISA model problems.

This study aims to further analyze the ability to solve mathematical problems in terms of extrovert-introvert personality types. This research method is descriptive qualitative research. The number of schools and students used as samples from this study was taken with multistage sampling techniques. The problem solving analysis used is based on the steps of Krulik and Rudnik. The personality types of extrovert students and introverted students do have a different mindset so that even though in some steps using the same representation, the tendency or habit to represent solving a problem uses different forms of representation. While the extrovert type is close to true when compared to introverted students

Solving problem is not only a goal of mathematical learning. Students acquire ways of thinking, habits of persistence and curiosity, and confidence in unfamiliar situations by learning to solve problems. In fact, there were students who had difficulty in solving problems. The students were naive problem solvers. This research aimed to describe the thinking process of naive problem solvers based on heuristic of Polya. The researcher gave two problems to students at grade XI from one of high schools in Palangka Raya, Indonesia. The research subjects were two students with problem solving scores of 0 or 1 for both problems (naive problem solvers). The score was determined by using a holistic rubric with maximum score of 4. Each subject was interviewed by the researcher separately based on the subject’s solution. The results showed that the naive problem solvers read the problems for several times in order to understand them. The naive problem solvers could determine the known and the unknown if they were written in the problems. However, they faced difficulties when the information in the problems should be processed in their mindsto construct a mental image. The naive problem solvers were also failed to make an appropriate plan because they did not have a problem solving schema. The schema was constructed by the understanding of the problems, conceptual and procedural knowledge of the relevant concepts, knowledge of problem solving strategies, and previous experiences in solving isomorphic problems.

Pre-service teachers in primary education often have difficulty in solving mathematical problems, specifically fractions that are presented with a picture. In solving problems, some thought processes are needed by the teacher to reduce students' cognitive barriers. Therefore, this study aimed to reveal the cognitive barriers experienced by students in solving fraction problems. The cognitive barriers referred to in this study are ways of thinking about structures or mathematical objects that are appropriate in one situation and not appropriate in another situation. This study employed a descriptive-qualitative method. Furthermore, participants were followed up with in-depth semi-structured interviews to find out the cognitive barriers that occurred in solving fraction problems. This study discovers that the participants, in solving fraction problems, experienced all indicators of cognitive barrier and two cognitive obstacles are found as new findings that tend to involve mathematical calculations and violates the rules in dividing images into equal parts in the problem-solving procedure.
