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.
