Abstract

Siswa kesulitan dalam menyelesaikan operasi penjumlahan dan pengurangan pada bilangan bulat. Hal ini dikarenakan kurangnya latihan dalam menyelesaikan masalah yang berkaitan dengan operasi bilangan bulat. Pembelajaran matematika yang dikaitkan dengan permainan tradisional akan membuat siswa melakukan latihan menyelesaikan operasi bilangan bulat secara berulang-ulang. Penelitian ini bertujuan untuk mengetahui penerapan permainan tradisional melalui inovasi permainan intingan (modifikasi) dalam pembelajaran matematika untuk mempermudah siswa dalam menyelesaikan operasi bilangan positif dan negatif. Metode dalam penelitian ini menggunakan deskripsi kualitatif dengan teknik pengumpulan data melalui observasi, wawancara dan dokumentasi untuk memvalidasi data menggunakan triangulasi. Penelitian ini dilaksanakan di SMP Idrisia-IGS Sampit, dengan subjek penelitian yaitu siswa kelas VII. Hasil dari penelitian ini menunjukkan bahwa permainan intingan (modifikasi) mampu membantu siswa menyelesaikan operasi bilangan bulat dalam membandingkan nilai bilangan bulat yaitu pada saat siswa mengumpulkan poin berupa bilangan bulat positif dan negatif pada saat melakukan permainan dan melakukan penjumlahan bilangan bulat positif dan negatif, hal ini dilakukan siswa pada saat menentukan pemenang dari permainan yang sudah dilakukan.

Abstract

Education is very important nowadays. Education plays an important role in improving human resources. Children are asked to be able to understand various sciences well, one of which is geometry in mathematics lessons. However, there are still many children who have difficulty getting a decent education, especially children with intellectual disabilities. This article aims to review effective learning methods for students with intellectual disabilities in understanding geometric material and being able to apply it in solving problems in real life contexts. One branch of mathematics that needs to be studied in depth is geometry. Since childhood, we have started to recognize objects that actually use geometric shapes. These objects are even simple objects that we often encounter around us. Apart from knowing the shapes and formulas in geometry, we are also expected to be able to apply geometry in everyday life. Students with intellectual disabilities are expected to have numerical abilities in solving geometry problems. This research uses a qualitative descriptive method by describing and analyzing data related to the discussion. Students with intellectual disabilities need learning media that can be more interactive and can increase understanding and creativity in thinking. By using artificial intelligence teachers can develop more effective learning media for students.

Abstract

The Metaphorical Thinking approach in learning mathematics algebra material in the Independent Curriculum provides students with a more meaningful experience of the understanding process because they can see, form and map mathematical concepts to experiential concepts to practice solving everyday life problems in Algebraic form. This research is a library research study supported by interviews at SMP Negeri 3 Sampit. The research was carried out by collecting data from various sources regarding the difficulties of Phase D (SMP) students in algebra material and the metaphorical thinking approach to see the achievement of meaningful understanding of mathematics. With the characteristics of Metaphorical Thinking, students can carry out mathematical problem-solving activities, especially algebraic mathematical problems, so as to find meaningful understanding. Then carry out data analysis using descriptive analysis to determine the effect of the metaphorical thinking approach on the daily life problem solving abilities of phase D students in algebra material.

Abstract

The aim of this research is to describe the use of project-based learning with the help of Android smartphones in trigonometric ratio material in grade X SMAN 1 Kota Besi. This research method is descriptive qualitative. The subjects of this study were tenth grade students SMAN 1 Kota Besi. Based on the results of reflections and interviews, it shows that the use of android aplication in project-based learning, namely (1) makes learning easier for students to understand and learning is more interactive because students experience it for themselves, (2) learning becomes more interesting because they use their gadgets for learning and practicum, and (3) students are more creative because they have to make reports and make presentations in front of the class. Thus the use of android aplication can support project-based learning on trigonometric ratio  material at SMAN 1 Kota Besi both inside and outside the classroom and outside of school.

Abstract

Problems in the reality of our lives require mathematics to be solved often using analogies in their solutions or also called metaphors. The condition of these problems requires students to develop abilities that emphasize the development of relationships between mathematical concepts and real phenomena in the surrounding environment. The method used in this study is descriptive qualitative with purposive sampling. The study was conducted at a public senior high school in Central Kalimantan during the 2024–2025 academic year, with 3 spatial students as subjects with Visual, Auditory and Kinesthetic learning styles in class X room H. This study aims to determine the metaphorical thinking process of students when solving trigonometry word problems. By using metaphorical thinking skills, students' mathematical understanding process becomes more meaningful because they can see, form, and map mathematical concepts to real concepts according to experience.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah matematis siswa ditinjau dari gaya belajar. Penelitian ini adalah penelitian kualitatif dengan pendekatan deskripsi kualitatif. Penelitian ini dilaksanakan di SMP Negeri 2 sampit. Subjek penelitian ini adalah 6 orang siswa dari 31 siswa dikelas VIII ruang A, 2 subjek visual dan 2 subjek auditorial. Instrumen yang digunakan yaitu angket gaya belajar, tes soal, dan wawancara. Data diperoleh dianalisis dengan cara reduksi data, penyajian data, dan penarik kesmpulan. Pengecekan keabsahan data menguunakan teknik triagulasi. Pemecahan masalah matematis dianalisis berdasarkan 4 indikator menurut Polya yaitu: (1) memahami masalah, (2) merencanakan pemecahan masalah, (3) menyelesaikan rencana pemecahan masalah, (4) mengecek/memeriksa kembali. Kemampuan pemecahan masalah matematis merupakan permasalahan yang diarahkan untuk mendapatkan suatu jawaban dengan cara berpikir. Berdasarkan hasil analisis data pemecahan masalah matematis siswa dengan menggunakan langkah Polya ditinjau dari gaya belajar adalah (1) Pada subjek SV1 dengan gaya belajar visual mampu dalam memahami masalah dengan cara membaca soal didalam hati, melakukan perencanaan pemecahan masalah, mampu melakukan perhitungan dengan tepat, dan tidak melakukan pemeriksaan kembali. Pada subjek SV2 dengan gaya belajar visual mampu dalam memahami masalah, melakukan perencanaan pemecahan masalah, belum mampu melakukan perhitungan dengan tepat, dan tidak melakukan pemeriksaan kembali. (2) Pada subjek SA1 dengan gaya belajar auditorial mampu dalam memahami masalah, melakukan perencanaan pemecahan masalah, mampu melakukan perhitungan dengan tepat, dan mampu melakukan pemeriksaan kembali hanya saja pada soal nomor 1 saja. Pada subjek SA2 dengan gaya belajar auditorial tidak mampu dalam memahami masalah dengan cara membaca soal didalam hati, melakukan perencanaan pemecahan masalah, mampu melakukan perhitungan dengan tepat, dan melakukan pemeriksaan kembali.
