STRATEGI DAN TINGKAT KEPEKAAN BILANGAN SISWA SEKOLAH DASAR DALAM MENYELESAIKAN MASALAH OPERASI BILANGAN BULAT

Susilahudin Putrawangsa

Abstract


Tujuan dari penelitian ini adalah untuk mengungkap tingkat kepekaan bilangan (Number Sense) siswa sekolah dasar dalam menyelesaikan masalah terkait dengan operasi bilangan bulat, yang meliputi operasi penjumlahan, pengurangan, dan perkalian. Penelitian ini adalah penelitian expose facto dengan pendekatan kualitatif. Responden dalam penelitian ini terdiri atas 5 orang siswa yang diambil secara acak dari sebuah Sekolah Dasar di Pulau Lombok. Data dikumpulkan melalui tes. Analisis data menggunakan tiga indikator kepekaan bilangan untuk menjawab dua pertanyaan penelitian. Hasil penelitian ini menunjukkan bahwa: Pertama, strategi yang digunakan siswa dalam menyelesaikan masalah terkait operasi penjumlahan, pengurangan, dan perkalian bilangan bulat adalah seragam dan terpaku pada penggunaan algoritma atau prosedur berhitung, yaitu prosedur penjumlahan bersusun, pengurangan bersusun, dan perkalian bersusun. Berdasarkan 3 indikator kepekaan bilangan, disimpulkan bahwa kepekaan bilangan siswa dalam penelitian ini tergolong rendah.
