Abstract

Pembelajaran penjumlahan dan pengurangan merupakan salah satu bahasan matematika awal yang dipelajari siswa di sekolah dasar. Keterampilan siswa dalam menjumlah dan mengurang kuantitas merupakan dasar yang penting agar siswa mampu bermatematika di jenjang mapun materi yang lebih kompleks. Sayangnya, seringkali pembelajaran penjumlahan dan pengurangan ini mengalami masalah dimana siswa sering tidak memahami prosedur yang digunakan, sehingga sebatas menghapal dan berujung pada kesalahan penggunaan prosedur. Masalah kedua yang teramati adalah siswa mengesampingkan esensi penting dari proses tersebut yang melibatkan suatu kepekaan bilangan (number sense). Melihat fenomena tersebut, dalam penelitian ini didesain sebuah lintasan pembelajaran untuk materi penjumlahan dan pengurangan dengan menggunakan pakem-pakem Pendidikan Matematika Realistik Indonesia, dengan harapan siswa dapat belajar materi ini dengan lebih bermakna. Metode penelitian yang digunakan adalah design research dengan tiga tahapan yang meliputi: preliminary design, teaching experiment dan retrospective analysis.
