Banyuwangi is a town part of Java island, Indonesia. Cultural of Banyuwangi still run by original society named Using tribe. One of the culture which still defended by Using tribe is custom house. The paper describe about house of Using Banyuwangi and instructional design that made from the result of explore activity. This research joining ethnography method and development research. While the data collecting done with observation method, interview, and documentation. As for study device developed with ADDIE model that limited at development step. The result showed that house of Using’s construction show the existence of mathematics concepts specially geometry two dimension, pythagoras, and similarity. This result used to developed the instructional design based on contextual teaching – learning. Selected items is pythagoras. The instructional design will be implementing at research hereinafter.
AbstrakPenelitian ini merupakan penelitian kuantitatif-kualitatif yang bertujuan untuk mendeskripsikan analisis tingkat kesukaran dan daya pembeda pada soal OMI(Olimpiade Matematika Integral) tingkat SMP khususnya pada soal pilihan ganda.Analisis soal dilakukan untuk mengetahui apakah soal yang dibuat sudah tergolong layak dan baik, serta memberikan hasil terbaik dalam mengukur kemampuan siswa.Penentuan subyek dilakukan dengan metode purposive sampling dan snowball sampling. Pengumpulan data dilakukan dengan metode dokumentasi dan wawancara.Data yang diperoleh dianalisis secara kuantitatif dan hasilnya dijabarkan secara deskriptif dengan metode kualitatif. Hasil Penelitian menunjukan tingkat kesukaran soal dari 20 soal OMI tingkat SMP terdapat 11 kategori sukar, 8 kategori sedang, 1 kategori mudah. Sedangkan berdasarkan daya pembeda maka soal tersebut termasuk 10 kategori sangat baik, 5 kategori cukup baik, 2 kategori sedang, 3 kategori buruk. Berdasarkan analisis data yang diperole dapat disimpulkan bahwa soal pilihan ganda pada OMI tingkat SMP masih membutuhkan perbaikan.Hal ini dilakukan karena masih ada daya pembeda yang masuk kategori buruk dan sedang, itu artinya daya pembeda pada soal tersebut memerlukan perbaikan, bahkan ada beberapa yang harus dibuang dan digantikan dengan pilihan jawaban yang baru.
Penelitian ini menggunakan metode kualitatif yang bertujuan untuk mengetahui kemampuan komunikasi matematis siswa ditinjau dari gaya belajar visual, auditorial, kinestetik pada materi aturan sinus dan cosinus. Penentuan responden dilakukan dengan metode purposive sampling dan snowball sampling. Dari setiap gaya belajar tersebut ditentukan masing-masing 3 subyek yang komunikatif untuk dilakukan wawancara sebagai proses triangulasi. Pengumpulan data dilakukan dengan metode tes dan wawancara. Data dianalisis secara kualitatif. Hasil penelitian menunjukkan : (1) siswa dengan gaya belajar visual dapat secara singkat menghubungkan benda nyata dan gambar ke dalam ide matematika, serta melakukan penarikan kesimpulan dari pernyataan matematika; (2) siswa dengan gaya belajar auditorial dapat mengubah kalimat menjadi ide matematika, menjelaskan ide-ide matematika (rumus), mengubah gambar peristiwa sehari-hari ke dalam simbol matematika, menjelaskan proses penyelesaian soal, serta dapat melakukan penarikan kesimpulan; (3) siswa dengan gaya belajar kinestetik dapat mengubah kalimat menjadi ide matematika, menjelaskan ide matematika dalam bentuk gambar dan rumus, serta mengubah gambar peristiwa sehari-hari ke dalam simbol matematika.Kata kunci : komunikasi matematis, gaya belajar ABSTRACTThis study uses qualitative methods that aim to determine students' mathematical communication skills in terms of visual, auditory, kinesthetic learning styles on the material sine and cosine rules. Determination of respondents is done by purposive sampling and snowball sampling methods. Each of these learning styles is determined by each of 3 communicative subjects for interviews as a triangulation process. Data collection is done by the method of tests and interviews. Data were analyzed qualitatively. The results showed: (1) students with visual learning styles can briefly connect real objects and images into mathematical ideas, as well as draw conclusions from mathematical statements; (2) students with an auditory learning style can convert sentences into mathematical ideas, explain mathematical ideas (formulas), change images of everyday events into mathematical symbols, explain the process of problem solving, and can make conclusions; (3) students with kinesthetic learning styles can convert sentences into mathematical ideas, explain mathematical ideas in the form of pictures and formulas, and transform images of everyday events into mathematical symbols.Keywords : mathematical communication, learning style
Angklung Paglak is a typical Banyuwangi angklung musical instrument that is heard from above using the tone of the Banyuwangian genre. Angklung Paglak has many things that can be explored to be used with mathematical concepts. The purpose of this study is to find out mathematics concept in angklung paglak Banyuwangi This research is exploratory-descriptive research. Data collection is done by literature review, observation, interviews and documentation. Data were analyzed by qualitative methods. The results of this study indicate that: (1) The characteristics of angklung paglak Banyuwangi in terms of shape and process are the same as the other Banyuwangi angklung types. Angklung paglak and other Banyuwangi angklung have differences in terms of many players. Paglak angklung players were 4 people, 2 angklung players and 2 drums players while the other Banyuwangi angklung players varied. (2) The mathematical concept in angklung paglak is about two or three-dimensional geometric shapes; traditional measurement units; concept of equating length to an object; and concept of equating length to an object.
