Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan pemecahan masalah matematis siswa. Kemampuan pemecahan masalah matematis merupakan kemampuan individu dalam memecahkan atau menemukan jawaban suatu masalah matematis. Tujuan penelitian ini adalah untuk mengetahui kemampuan pemecahan masalah matematis siswa pada materi aritmatika di MTsS Pondok Modern dan Tahfidz Nurul Jannah. Prosedur penelitian ini dimulai dari pengembangan instrumen, pemberian soal tes, penentuan subjek, dan wawancara. Berdasarkan hasil analisis data diketahui bahwa analisis kemampuan pemecahan masalah matematis siswa di Kelas VII MTsS Pondok Modern dan Tahfidz Nurul Jannah berdasarkan indikator kemampuan pemecahan masalah menurut Polya siswa dikategorikan menjadi tiga kelompok yaitu siswa dengan kategori tinggi, siswa dengan kategori sedang, dan siswa dengan kategori rendah. Berdasarkan hasil penelitian, siswa mengalami kesulitan dalam pemecahan masalah matematis. Hal ini disebabkan oleh kurangnya latihan dan kebiasaan dalam mengerjakan soal pemecahan masalah serta kurangnya pemahaman terhadap soal. Kemampuan siswa dalam tahapan Polya meningkat saat mereka mampu membuat kesimpulan dari pekerjaan mereka. Pembelajaran berbasis masalah dengan pendekatan Polya sangat penting untuk meningkatkan kemampuan pemecahan masalah siswa, membantu mereka mengembangkan langkah-langkah pengerjaan soal secara lengkap, dan memperluas wawasan yang dapat diterapkan dalam kehidupan sehari-hari.

Abstract

The Hatam tribe is one of the sub-tribes of the Arfak tribe. This study aims to explore the numeracy culture of the Hatam Tribe spoken by the Hatam Tribe community who inhabit Nuhuwei Village, Ransiki District. This research is ethnographic. The techniques used for data collection are interviews, exploration, literature study, desk study, and documentation. Interviews and explorations were conducted with several elders who spoke the Hatam language in Nuhuwei Village. Literature and documentation studies were conducted by looking for other sources of information related to the previously existing Hatam language to obtain accurate results. The Desk Study was conducted to find out the mathematical patterns of the Hatam Tribe. The results obtained from this study are that mathematically, the counting patterns spoken by the Hatam people who inhabit Nuhuwei Village have different dialects from the speech of the Hatam people who inhabit other areas. Besides that, another finding is that the pattern of mentioning numbers spoken by the Hatam tribe inhabiting Nuhuwei Village correlates with the counting pattern on the Jarimatika. We call this latest finding related to counting using the Hatam language-based Jarimatika as Himatam (Calculating Using Jarimatika in the Hatam language). This finding shows that learning numeracy for elementary students in Nuhuwei Village can be done more easily using the Himatam Method.

Abstract

This study intended to investigate the creative thinking dispositions of students who can perform truth-seeking in solving mathematical problems. Truth-seeking behavior tends to show students' thinking disposition when they need to solve math problems. This behavior is very much needed by students in solving math problems, especially HOTS-type questions. This study is qualitative and employs a phenomenological approach. Three students from the Integrated Islamic Junior High School in Manokwari who sought the truth served as research subjects. Their answers on the answer sheets encouraged the determination of the subjects’ tendencies in truth-seeking and creative thinking. The results of thought-based and task-based interviews were then incorporated into the analysis to determine the creative thinking dispositions of truth-seeking students and the relationship between truth-seeking and creative thinking dispositions. The findings of this study indicate that all research subjects have diverse creative thinking dispositions; the more truth-seeker indicators that are met, the more creative thinking dispositions they possess. When solving mathematical problems, students tend to show how they think by how hard they try to find the truth. This result implies that it needs more research on the level of creative thinking disposition and how to increase students' true search.

Abstract

A well-constructed concept can aid pupils in comprehending any learning content. However, as seen by how students solve math problems, the construction process frequently encounters flaws. Students make various conceptual construction errors in online learning. This is a qualitative study conducted on Mathematics Education students of Universitas Papua. The purpose of this study was to determine the errors made by students in constructing concepts of functions during online learning. Five subjects were selected as the subjects. They were chosen by using the purposive sampling technique. The instrument was developed using material from online lectures on functions and has been validated by experts in the field of mathematics education. The findings indicated that there were five misconstruction concepts, i.e. pseudo construction, construction holes, mis-logical construction, mis-analogical construction, and misconstruction in problem-solving. For further research, to avoid unnecessary construction errors, it is recommended that before the learning process is carried out, the teacher should know the construction of students’ concepts, so that the process of students’ conceptual change in online learning can be known.

Abstract

This study aims to analyze students' perceptions of polyhedral constructions in terms of the Van Hiele theory of geometric thinking levels. The method used was descriptive research with a qualitative approach involving 26 ninth-grade students of SMP YAPIS Manokwari. Data were collected through tests and interviews. The tests were used to identify students' geometric thinking levels, while the interviews were conducted to explore students' perceptions of polyhedral constructions and to verify the test results. The data were analyzed through data reduction, data display, and conclusion drawing. The findings revealed that the students were at the visualization and analysis levels. Students at the visualization level tended to understand three-dimensional figures based on their visual appearance and observable shapes, whereas students at the analysis level were able to identify component solids and recognize several geometric properties used in problem solving. However, students at both levels still experienced difficulties in understanding the relationships among the parts of composite solids comprehensively. In conclusion, students' perceptions of polyhedral constructions develop in accordance with their geometric thinking levels. Therefore, geometry instruction should be adjusted to students' stages of thinking in order to support the development of a deeper understanding of geometric concepts.   Keywords: Geometry, Perception, Van Hiele Theory, Level of thinking

Abstract

This study aims to analyze the influence of the mathematical problem-solving abilities of 10th-grade students at Advent High School in Manokwari on the topic of geometric sequences and series based on Polya’s theory. The method used was a mixed-methods approach with a sample of 30 students. Data were collected through written tests and interviews. The results showed that students’ problem-solving skills fell into the high category (20%), the moderate category (53.33%), and the low category (26.67%). The best regression model obtained was Ŷ = -32.914 + 35.797X₁ + 75.199X₂ - 60.017X₄ + ε, with a coefficient of determination of 46.9%. In conclusion, the ability to understand problems and formulate solution plans are the factors that most influence students’ success in solving geometric sequences and series problems; therefore, mathematics instruction needs to place greater emphasis on developing students’ ability to understand problems, design solution strategies, and think systematically.   Keywords: Geometric Sequences and Series, Problem-Solving Skills, Backward Method, Polya’s Theory

Abstract

This research aims to analyze college students’ problem-solving abilities in solving non-routine promblems on the topic of limits. The type of research employed is descriptive qualitative. The research subjects were 15 mathematics students at Universitas Papua. From the total subjects, 4 students were selected using a purposive sampling technique as focus subjects for in depth interviews, consisting of two subjects from the moderate category and two subjects from the low category. Data analysis was conducted based on Polya’s problem-solving stages: understanding the problem, devising a plan, carrying out the plan, and looking back. The results indicated that the majority of students were in the low ability category (12 students) and the remaining were in the moderate category (3 students0. Moderate category subjects were able to understand the problem well and write down fairly systematic resolution steps, but lacked precision in final execution. Meanwhile, low category subjects showed effort to resolve the problems but faced major obstacles during the stages of devising and carrying out plans due to weak understanding of prerequisite concepts, and all subjects tended to neglect the looking-back stage. In conclusion, students’ problem-solving ability in solving non-routine limit problems is dominated by the low category. Learning approaches that habituate students to solving non-routine tasks and strengthening metacognitive aspects in re-evaluating their work are highly required.   Keywords: Problem-Solving Ability, Non-Routine Problems, Limit, Polya
