Abstract

Penelitian ini bertujuan untuk mendeskripsikan pemecahan masalah mahasiswa calon guru yang berkemampuan tinggi dalam memecahkan masalah kontekstual. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif. Subjek dari penelitian ini yaitu mahasiswa calon guru Program Studi Pendidikan Matematika Unidayan Bau-bau yang berkemapuan matematika tinggi. Pada penelitian ini, pengumpulan data dilakukan melalui tugas berupa pemberian soal  kepada subjek penelitian. Prosedur tugas ini adalah mahasiswa diberikan soal dalam waktu yang telah ditentukan peneliti, kemudian dilakukan wawancara sebelum dan setelah mahasiswa mengerjakan soalyang diberikan. Tehnik analisis data yang digunakan terdiri dari tiga aktivitas secara berkelanjutan yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukan bahwa dalam memecahkan masalah kontekstual pada tahap memahami masalah, yaitu menyajikan kembali apa yang diketahui dan ditanyakan. Tahap merencanakan yaitu membuat model matematika, membuat tabel, menentukan fungsi kendala dan fungsi objektif. Tahap menyelesaikan  masalah yaitu menggambar grafik, mencari titik perpotongan, mencari daerah penyelesaian, dan menguji titik pojok. Tahap memeriksa kembali yaitu melakukan kroscek kembali terkait yang diketahui dan ditanyakan, mengabaikan hasil yang tidak sesuai dengan masalah, kemudian untuk nilai yang maksimum, maka nilai tersebut diabaikan karena tidak sesuai dengan masalah, dan mengungkapkan bahwa model matematika dapat menyelesaikan masalah, dan model matematika telah diperiksa kembali.

Abstract

Mathematical representation ability is one of the basic abilities that every student must have in examining, expressing, and exploring a mathematical idea in the form of a problem, information, definition, etc. to find an appropriate solution according to the results of the representation, whether in the form of pictures, words, tables, symbols, graphs, and patterns in mathematics. The biggest reason that hinders students' bright ideas from appearing is the weak ability of students' mathematical representations which hinders students in determining the completion of mathematical problems and even less careful in reading story problems, weak in problem analysis, inaccurate, and difficulty connecting between concepts. The subjects of this study were students of grade VIII in one of the MTs in the Angkona sub-district, which consisted of two students. The instrument used for this research is the Visualizer Verbalizer Questionnaire (VVQ). Mathematical representation ability test questions and interviews. This study used descriptive qualitative method. Based on the data analysis, it can be concluded that the students' representation abilities with the visualizer and verbalizer styles are quite good. There are several interesting things from the two research subjects, namely the Visualizer subject (SVi) in solving a problem prioritizing the visual aspect in examining each question and the information contained in the a simpler form in representing an image and illustration of a flat shape. Meanwhile, the subject verbalizer (SVe) is more likely to explore detailed and clear information in representing something related to the Pythagorean theorem.

Abstract

The Baruga Adat of Lawela Village is a traditional building in the form of an open stilt house with a tiered roof that holds social, cultural, and mathematical value. This study explores the ethnomathematical elements of the Baruga Adat of Lawela Village and examines its symbolic meanings in relation to planar shapes. The study used a qualitative approach with an ethnographic design. Data were obtained through observation of the Baruga structure, interviews with traditional leaders and the Culture Office of South Buton Regency, and documentation in the form of photographs and field notes. Data analysis used data reduction, data display, and descriptive conclusion drawing. The results show that the Baruga Adat of Lawela Village contains various planar shapes, namely triangles, squares, rectangles, rhombuses, trapezoids, and parallelograms. These shapes not only demonstrate the application of geometric concepts in the building's structure but also carry symbolic meanings related to the community's worldview, such as the triangle, which symbolizes the three-layered cosmology of the world, the square, which reflects the four pillars of life, and the rectangle, which represents the deliberation space. These findings extend ethnomathematical studies of traditional buildings by revealing the relationships among geometric forms, spatial functions, and symbolic meanings within the cultural context of the Lawela Village community. Thus, the Baruga Adat of Lawela Village functions not only as a social and cultural center but also represents local mathematical knowledge that can be developed as a source of contextual mathematics learning while supporting the preservation of local culture.

Abstract

Abstract Mathematical modelling is an alternative that can be used by student in term of contextual problem solving. The aim of this studi is to analyze about student’s mathematical modelling to solve the contextual problem based on their math ability. This research is a descriptive research by using kualitative method. There are some steps in doing this research, , they are: 1) preparing research instrument, , that is math ability test, contextual problem solving test, and interview guide, 2) validation the instrument test end interview guide, 3) instrument trials, 4)research implemntation, 5) data analysis, 6) data triangulation, and 7) conclusion. Based on the research result, there are three steps of student’s ability, i.e , high, medium, and low. The ability of these there student’s show that there are differences in solving contextual problems using mathematical modelling. Keywords: Mathematical modelling, contextual problem solving Abstrak Pemodelan matematika merupakan salah satu alternatif yang dapat digunakan oleh siswa dalam pemecahan masalah kontekstual. Tujuan penelitian ini yaitu untuk menganalisis tentang pemodelan matematika siswa dalam pemecahan masalah kontekstual berdasarkan kemampuan matematika. Penelitian ini adalah penelitian deskriptif dengan pendekatan kualitatif. Tahapan dalam peneltian ini meliputi: (1) penyiapan instrumen penelitian berupa tes kemampuan matematika, tes pemecahan masalah kontekstual dan pedoman wawancara, (2) validasi instrumen tes dan pedoman wawancara, (3) uji coba instrumen, (4) pelaksanaan penelitian, (5) analisis data, (6) triangulasi data, dan (7) penarikan kesimpulan. Berdasarkan hasil penelitian, diperoleh tiga kemampuan siswa yaitu tinggi, sedang, dan rendah. Kemampuan ketiga siswa tersebut menunjukan bahwa terdapat perbedaan dalam memecahkan masalah kontekstual menggunakan pemodelan matematika. Kata Kunci: Pemodelan Matematika, Pemecahan Masalah Kontekstual
