| Summary: | Abstract This research is used for (1) knowing the understanding of fourth grade students of elementary school in finding polygon area concept through square-grid Tangram; (2) resulting the learning trajectory for the student in learning polygon area through square-grid Tangram by having approaching PMRI to the fourth grade students. This research involved 26 students of fourth grade at Az-Zahrah Palembang. It used design research methodology of learning polygon area through square-grid Tangram included preparing for experiment steps, teaching experiment, and retrsospective analysis. It's resulted Learning Trajectory which is connected to the three learning process activities, hence: (1) determine kinds of plane figure and plane partitioned (using any kinds of employment context); (2) determine the area ofsquare unit (using square-grid Tangram); (3) founding algorithm of polygon area. The result shown by using PMRI approach, square-grid Tangram is useful as a model to support the students in finding polygon concepts. Keywords: Polygon area, Square-grid Tangram, design research, PMRI Abstrak Penelitian ini bertujuan (1) untuk mengetahui pemahaman siswa kelas IV Sekolah Dasar dalam menemukan konsep luas segi banyak menggunakan Tangram berpetak; (2) menghasilkan lintasan belajar bagi siswa melalui Tangram berpetak dalam pembelajaran luas segi banyak menggunakan pendekatan PMRI di kelas IV. Penelitian dilaksanakan di SD Islam Az-Zahrah Palembang yang melibatkan 26 orang siswa kelas IV. Metode yang digunakan adalah design research pembelajaran luas segi banyak menggunakan Tangram berpetak melalui tahap-tahap preparing for the experiment, teaching experiment, dan retrospective analysis. Penelitian ini menghasilkan Learning Trajectory yang memuat serangkaian proses pembelajaran dalam 3 aktivitas yaitu: (1) menentukan jenis bangun datar dan mempartisi bangun (menggunakan konteks berbagai pekerjaan); (2) menentukan luas dengan persegi satuan (menggunakan Tangram berpetak); (3) menemukan algoritma luas segi banyak. Hasil dari percobaan pembelajaran menunjukkan bahwa dengan pendekatan PMRI, Tangram berpetak berperan sebagai model yang mendorong siswa menemukan konsep luas segi banyak. Kata Kunci: Luas segi banyak, Tangram berpetak, design research, PMRI |
