Abstract

AbstractThe purpose of this study is to describe mathematical communication skills in statistical material. This research is a descriptive qualitative research. The research subjects were students of class XII MIA at SMA Negeri 3 Tarakan, totaling 4 students with 2 students each having high written communication skills, and 2 students having low mathematical communication skills. Data collection methods used were written mathematical communication tests and interviews. The written mathematical communication test data is also used as a basis for grouping students. The results showed that students' high mathematical communication skills in high statistical material were able to reach 6 mathematical indicators namely expressing, demonstrating, describing, interpreting, writing, and making conclusions. Students’ low mathematical communication skills in statistical material were able to reach 3 mathematical indicators namely expressing, demonstrating, and interpretingKeywords: Mathematical Communication Writing, StatisticAbstrakTujuan penelitian ini adalah mendeskripsikan kemampuan komunikasi matematis pada materi statistik. Penelitian ini merupakan penelitian kualitatif deskriptif. Subjek penelitian yaitu siswa kelas XII MIA di SMA Negeri 3 Tarakan yang berjumlah 4 siswa dengan masing-masing 2 siswa yang memiliki kemampuan komunikasi tulis tinggi, dan 2 siswa yang memiliki kemampuan komunikasi matematis rendah. Metode pengumpulan data yang digunakan ialah tes komunikasi matematis tulis dan wawancara. Data hasil tes komunikasi matematis tulis digunakan juga sebagai dasar pengelompokkan mahasiswa. Hasil penelitian menunjukkan bahwa kemampuan komunikasi matematis tulis siswa kemampuan tinggi pada materi statistik mampu mencapai 6 indikator matematis yaitu mengekspresikan, mendemonstrasikan, menggambarkan, menginterprestasikan, menuliskan, dan membuat kesimpulan. Kemampuan komunikasi matematis tulis siswa kemampuan rendah pada materi statistik mampu mencapai 3 indikator matematis yaitu mengekspresikan, mendemonstrasikan, dan  menginterprestasikan.Kata kunci: Komuikasi Matematis Tulis, Statistika

Abstract

This study aims to identify the level of students' mathematical arithmetic skills in solving problems in the summing material based on counting on in class II of SD Negeri 018 Tarakan. The method used is a quantitative approach to the type of descriptive explanation. The results of the study were obtained from the students' numeracy ability test results based on the mathematics numeracy ability category of students in the high and medium categories. The problems used to identify the ability to count scheme are three problems, namely problems related to counting on, counting all, then counting on and counting all. The results of students' math skills based on the counting on scheme were obtained through interviews with 25 research subjects. Problem 1 was solved by students with a counting scheme of 10 students (40%), Problem 2 was solved by students with a counting scheme of 1 student (4%). Problem 3 is solved by students with a counting on scheme of 2 students (8%).

Abstract

This research aimed to describe the role undertaken by teachers at SMP Negeri 1 Tarakan, one of the public junior high schools in Tarakan, Indonesia, in preparing their students to succeed in mathematics competitions. This qualitative research employed a case study approach. The data collection techniques included interviews, documentation, and observation. The data analysis consisted of several interactive steps: preparing the collected data, reading it repeatedly to comprehend it, coding, identifying and testing themes through triangulation and member checking, describing the established themes, interpreting the themes and descriptions, and drawing conclusions. We also conducted peer debriefing during coding and writing research reports. Based on the data analysis, the findings regarding the role of teachers in preparing students for participation in mathematics competitions in the school consisted of two categories: students selection and coaching. Mathematics teachers select students through two main steps: set criteria and analyze students’ mathematical abilities. While coaching students to prepare for competition participation, teachers employed a personalized approach, facilitated student learning, motivated students, and utilized resources and facilities.Keywords: case study, mathematics competition, mathematics in junior high school, teacher roles. Penelitian ini bertujuan untuk mendeskripsikan hal yang dilakukan oleh guru di SMP Negeri 1 Tarakan dalam mempersiapkan siswanya untuk meraih prestasi dalam kompetisi Matematika. Jenis penelitian ini adalah kualitatif dengan pendekatan studi kasus. Adapun teknik pengumpulan data adalah wawancara, dokumentasi, dan observasi. Analisis data yang dilakukan terdiri dari beberapa langkah interaktif: mempersiapkan data yang telah terkumpul, membaca berulang-ulang untuk memahami semua data, melakukan pengkodean, menentukan tema dan mengujinya melalui triangulasi dan memeriksa anggota, mendeskripsikan tema yang sudah ditetapkan, menginterpretasi tema dan deskripsi tersebut, dan menarik kesimpulan. Sepanjang melakukan pengkodean dan penulisan laporan penelitian, kami juga melakukan peer debriefing. Berdasarkan hasil analisis data, temuan tentang bagaimana peran guru dalam mempersiapkan siswa untuk mengikuti kompetisi Matematika  di sekolah tersebut terdiri dari dua kategori: memilih siswa dan melakukan pembinaan. Guru Matematika memilih siswa dengan dua langkah utama, yaitu menetapkan syarat dan menganalisis kemampuan Matematika siswa. Selama membina siswa untuk mempersiapkan mereka mengikuti kompetisi, guru melakukan pendekatan personal, memfasilitasi siswa dalam belajar, memotivasi siswa, dan memanfaatkan sarana dan prasarana.Kata kunci: kompetisi Matematika, Matematika SMP, peran guru, studi kasus.
