Abstract

The study aims to design mathematics learning in composite function concepts with farm tools, which are thrasher and rice mill machines; this farm’s tool is used as to starting point in the learning process. The research method used is design research with a  preliminary design, design experiment, and analysis retrospective stages. This study describes the design of the thrasher and rice mill machine to facilitate a real contribution for student understanding of the composite function concept. The participant of this research is 10 eleventh-grade students from one of the senior high school in East Java. The results of this study reveal that students are able to make associations from the thrasher and rice mill machine through the determination of the input and output of the machines to the formula of the composite function concept. So, the stages in the learning trajectory have an important role in understanding the composition function concept from informal level to formal level and also make the study of mathematics more easy, simple, fun, and comfortable.

Abstract

This study aims to classify student responses in dealing with probabilistic problems according totheir level, analyze, and identify indicators at each level. This study used a descriptivequalitativeapproach with data collection techniques in the form of tests and interviews which were tested on 66 seventh grade students as research subjects. The results showed that 28 students were at the subjective level, 30 students were at the transitional level, and 8 students were at the informal quantitative level, and no students were at the numerical level. In addition, there are additional indicators at the subjective and transitional levels. Meanwhile, at the informal quantitative level, there are no additional indicators.Keywords: probabilistic thinking

Abstract

Etnomatematika merupakan konsep matematika yang terdapat di dalam suatu budaya. Tujuan penelitian ini adalah mengkaji etnomatematika pada tradisi methik pari yang ada di Desa Pamotan, Kecamatan Dampit, Kabupaten Malang, Jawa Timur. Desain penelitian ini yaitu etnografi. Instrumen yang digunakan dalam penelitian ini adalah wawancara dan dokumentasi. Hasil penelitian menunjukkan bahwa tradisi methik pari telah menjadi kepercayaan dan kebiasaan yang dilaksanakan secara turun temurun oleh masyarakat tani Desa Pamotan. Tradisi ini juga dilakukan sebagai bentuk ucapan syukur atas kelancaran dalam bercocok tanam. Aktivitas fundamental matematis yang diperoleh meliputi menghitung yang memuat konsep peluang, penjumlahan, pengurangan dan pembagian, menempatkan yang memuat konsep perbandingan, mendesain yang memuat bentuk-bentuk geometri seperti persegi, persegipanjang, lingkaran dan kerucut, bermain yang memuat konsep penentuan nilai optimum dan menjelaskan yang memuat konsep himpunan.

Abstract

Digital literacy is a skill that learners must have. This ability is the basis in shaping students' critical and creative reasoning. In shaping students' mathematical literacy, interesting learning media is needed. This learning media can be in the form of ICT or Manipulative. The RIMath application is an android-based learning media that can facilitate students' mathematical literacy. RIMath learning media presents mathematics learning that applies contextual problems while integrating the Qur'an. The type of research used in this study is R&D (Research and Development) using the 4D method (Define, Design, Develop and Disseminate). RIMath learning media will be validated to experts to ensure the quality of this learning media. RIMath learning media will also be tested with students to ensure that the RIMath application can facilitate students' mathematical literacy. RIMath learning media gets a feasibility percentage of 78.283%. This percentage proves that RIMath learning media is included in the "feasible" category to be used by students in learning mathematics. In a t-test experiment, RIMath learning is proven to improve students' mathematical literacy by working on math problems.
ANALISIS KEMAMPUAN SISWA BERKEBUTUHAN KHUSUS TUNARUNGU DALAM MEMECAHKAN MASALAH KONTEKSTUAL TOPIK BILANGAN BULAT [ANALYSIS OF DEAF STUDENTS’ ABILITY TO SOLVE CONTEXTUAL PROBLEMS ON INTEGER TOPICS] Lidiana Fitria Ningsih; Halimatus Sakdiyah; Ulfa Masamah

Abstract

This study aims to analyze the ability of deaf students to solve mathematical word problems on integer topics, particularly addition and subtraction operations. The study employed a descriptive qualitative approach involving two deaf junior high school students from a special education school in Batu City. Data were collected through problem-solving ability tests, interviews, observations, and documentation. Data analysis was conducted using the Miles and Huberman model, which includes data reduction, data display, and conclusion drawing, and was further examined based on Polya’s four stages of problem solving. The findings revealed that deaf students experienced difficulties in the stages of understanding the problem and devising a plan, especially in interpreting word problems related to integer operations. However, during the stages of carrying out the plan and reviewing the solution, the students were able to perform calculations accurately. Therefore, mathematics instruction for deaf students should incorporate visual aids, simplified language explanations, and contextual word problem exercises to enhance students’ understanding in the early stages of problem solving. BAHASA INDONESIA ABSTRACT: Penelitian ini bertujuan untuk menganalisis kemampuan siswa tunarungu dalam menyelesaikan soal cerita matematika pada materi bilangan bulat, khususnya operasi penjumlahan dan pengurangan. Penelitian menggunakan pendekatan kualitatif deskriptif dengan subjek dua siswa tunarungu tingkat SMP di salah satu sekolah luar biasa di Kota Batu. Data diperoleh melalui tes kemampuan pemecahan masalah, wawancara, observasi, dan dokumentasi. Analisis data dilakukan dengan model Miles dan Huberman yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan, serta dikaitkan dengan empat tahapan pemecahan masalah Polya. Hasil penelitian menunjukkan bahwa siswa tunarungu mengalami kesulitan pada tahap memahami masalah dan merencanakan penyelesaian, terutama dalam menafsirkan kalimat soal yang berkaitan dengan operasi bilangan bulat, sedangkan pada tahap melaksanakan rencana dan memeriksa kembali siswa mampu melakukan perhitungan dengan baik. Oleh karena itu, pembelajaran matematika bagi siswa tunarungu perlu menggunakan bantuan visual, penjelasan bahasa yang sederhana, dan latihan soal cerita kontekstual untuk meningkatkan pemahaman pada tahap awal pemecahan masalah.
