PENGARUH PENDEKATAN REALISTIC MATHEMATICS EDUCATION TERHADAP KEMAMPUAN BERPIKIR KRITIS DAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SEKOLAH DASAR

Kemampuan berpikir kritis dan kemampuan pemecahan masalah matematis merupakan kemampuan yang sangat penting yang harus dimiliki siswa Sekolah Dasar. Hal ini akan membantu dalam mengembangkan potensi dirinya, dengan menitikberatkan pada kemampuan dalam berpikir dan bertindak secara normatif, dan siap bernalar dari apa yang dilihat maupun didengar sehingga dapat menyelesaikan permasalahan yang dihadapinya dalam kehidupan sehari-hari, oleh karena itu peranan guru sebagai tenaga pendidik secara professional menjadi penentu dalam menjembatani siswa melalui pembelajaran yang berkualitas. Namun kenyataannya berkaitan dengan proses pembelajaran matematika di SD proses pembelajaran yang dilaksanakan belum memberikan kesempatan siswa dalam menggali potensi dirinya dalam berpikir kritis dan menyelesaikan permasalahan. Sehingga perlu dicari alternatif pembelajaran yang dapat meningkatkan kemampuan berpikir kritis dan kemampuan pemecahan masalah. Pendekatan Realistic Mathematics Education merupakan salah satu alternatif yang digunakan untuk meningkatkan kemampuan berpikir kritis dan kemampuan pemecahan masalah matematis. Penelitian ini bertujuan untuk mengetahui apakah pendekatan Realistic Mathematics Education dapat meningkatkan kemampuan berpikir kritis dan kemampuan pemecahan masalah matematis dalam pembelajaran matematika di Sekolah Dasar. Penelitian ini dilaksanakan menggunakan metode kuasi eksperimen dengan desain kelompok kontrol non-Ekuivalen. Sampel dalam penelitian adalah siswa kelas IV pada salah satu SD di Kabupaten Garut.
