The purpose of this study was to describes the use of student’s contribution as a transition tool at each level of learning the fraction operation concept. This study involved fourth grade students of an elementary school in Ngada East Nusa Tenggara. The type of this research is Design Research with three stages, namely: initial design, teaching experiment and retrospective analysis. This research begins conduct a hypothetical learning trajectory (HLT) of fraction operations concept. The HLT has been tested before the actual learning process (ALT). The results of the retrospective analysis obtained an overview of the Actual Learning Trajectory (ALT) show that the use of various student’s contribution at each level of learning can lead to understanding the fraction operation concept.

Abstract: Plays is joyfull activity for Elementary School Students.Â This reality as something advatages for using that in mathematics learning. There areÂ some spaces in Realistic Mathematics Education Approach for using plays as starting point to developing mathematical concept. This paper describes some examples about using play activities as context for facilitate students learning mathematics with meaning and joyfull.Abstrak: Bermain merupakan kegiatan yang menyenangkan bagi anak usia Sekolah Dasar. Kenyataan ini merupakan sesuatu yang menguntungkan untuk digunakan dalam pembelajaran matematika. Pendekatan Pendidikan Matematika Realistik (PMR) memberi ruang untuk menggunakan aktivitas bermain sebagai starting point pengembangan konsep matematika. Makalah ini menyajikan contoh bagaimana sebuah aktivitas bermain dapat digunakan sebagai konteks untuk memfasilitasi siswa belajar matematika secara bermakna danÂ menyenangkan.Kata Kunci: aktivitas bermain, konteks, matematika realistik

AbstractTeaching and learning can be successful and meaningful if it uses a design that is close to students, namely the cultural context.Â This study aims to explore the mathematical content of the sabuk tradisional in the saboweki/traditional clothing of the Bajawa ethnic community, East Nusa Tenggara Province. The research method used descriptive qualitative with an ethnographic approach. Research object was sabuk tradisional Bajawa (keru). The data was collected through observation and documentation, while the source triangulation technique used to obtain the validity of the data. Data analysis techniques started from exposure, reduction and conclusion. The results showed that sabuk tradisional (keru) bajawa contains mathematical concepts including number patterns, multiplication as repeated addition, geometry and measurement and reflection. The findings of this study could improve the quality of learning in elementary schools through the sabuk tradisional (keru) bajawa as a mathematics learning media based culturally responsive.

Tujuan penelitian ini adalah untuk mengetahui perkembangan belajar operasi pecahan siswa sekolah dasar menurut teori Gravemeijer di Kabupaten Ngada NTT. Jenis penelitian kualitatif fenomenologi digunakan untuk mencapai tujuan penelitian. Dalam penelitian ini Hypothetical Learning Trajectory (HLT) memainkan peranan penting sebagai instrumen penelitian. Perangkat pembelajaran yang disusun untuk menjalankan serangkaian aktivitas belajar dalam HLT telah dikonsultasikan dengan dua orang ahli Pembelajaran Matematika selanjutnya diuji coba pada kelompok kecil yaitu lima siswa Kelas IV Sekolah Dasar Katolik Bomari Langa pada tahap eksperimen pilot. Selanjutnya HLT dibandingkan dalam proses pembelajaran sebenarnya pada tahap eksperimen pengajaran dengan 24 siswa. Berdasarkan analisis ditemukan bahwa siswa dapat berkembang dalam belajar operasi pecahan dengan menggunakan tingkat aktivitas yang berbeda berdasarkan pendekatan PMR menurut teori Gravemeijer. Pada level pertama yaitu level situasional, Drama Matematika dapat menstimulasi pengetahuan informal siswa tentang prosedur operasi penjumlahan dan pengurangan pecahan. Pada level referensial, untaian manik-manik dan kartu pecahan menjadi model dari situasi drama matematika yang merupakan jembatan menuju gagasan penggunaan garis bilangan untuk operasi penjumlahan dan pengurangan pecahan. Pada level ketiga yaitu level general, siswa dapat menggunakan garis bilangan sebagai model untuk operasi penjumlahan dan pengurangan pecahan. Pada level formal, dengan bantuan untaian bilangan membawa siswa mengkonstruksi soal cerita sendiri dan menyelesaikan soal cerita yang dihasilkan dengan prosedur formal operasi penjumlahan dan pengurangan pecahan. Kata Kunci: Teori Gravemeijer, hipotesis trayektori belajar, penjumlahan dan pengurangan pecahan.

This article aimed to explore ethnomathematics in the Malind tribe to strengthen the character values of elementary school students. The method used descriptive survey method with data collection techniques such as observation, interviews, and literature review. The researchers act as a human instrument. The qualitative data were obtained and then analyzed by paying attention to ethnomathematics material or theme. The results showed: firstly, ethnomathematics in the culture of the Malind tribe was found in activities of daily life such as the manufacture of farming tools, hunting, fishing, musical instruments, noken, ornaments and paintings, traditional ceremonies, life behaviors, and traditional games. Second, the attitude of responsibility, like to work hard, practice religious values, develop creativity, friendship, responsibility, the spirit of cooperation and kinship and tolerance is an integrated national character in the cultural values of the Malind tribe. Ethnomathematics can be integrated into learning mathematics in elementary schools Keywords: Ethnomathematics, Malind Tribe, Education Character
