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 objective of this study is to create a case-method-based interactive e-module that will enhance the higher-level thinking skills (HOTs) of students. Research and Development (R&D) utilizing the ten-step Borg & Gall model development constitutes this research method. This investigation is restricted to the seventh stage. This study's participants were FKIP UNIPA first-semester students enrolled in instructional mathematics courses. The sample for the study was determined by cluster random sampling. The participants in this research were partitioned into two groups: the experimental group consisted of students majoring in English education, while the control group comprised students majoring in Indonesian language education. In this study, questionnaires, interviews, validator assessment forms, and HOTs tests were utilized to collect data. Three data analysis techniques were utilized in this study: validity, practicability, and effectiveness. The outcomes demonstrate the e-module's validity. The practicality assessment yielded an 81.44% response rate from students in the very practical category. The HOTs of the pupils in the experimental class were superior to those of the control class. The mean HOTs of students in the control group were 67.67, whereas those in the experimental group have an average HOTs of 75.50.

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.
