IMPLEMENTASI PEMBELAJARAN MATEMATIKA REALISTIK UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KOMPUTASIONAL SISWA
Abstract
Computational thinking is a type of problem-solving ability using logical thinking that students do with regular steps. This cognitive ability is one of the important skills in supporting students with mathematical concepts. However, the advantages of computational thinking do not seem to be paid much attention to by education, especially in Indonesia. This is because the learning approach does not emphasize the positive aspects that can improve students' computational thinking. As a result, the average computational thinking ability of students is low. This type of research uses an experimental method of pretest-posttest control group design. The population involved was class XII students at MA Daruttauhid Malang, which consisted of 22 students in the experimental class, and 24 students in the control class. The research data is in the form of pre-test scores before being given realistic mathematics learning treatment, and post-test score data. The results obtained showed that the computational thinking ability of students in the experimental class was higher than in the control class. To be clear, this fact is measured by calculating the N-Gain scores of students in the experimental class with a value of 0.7 (high category), and the N-Gain scores of control class students with a value of 0.5 (medium category).
Abstrak
Berpikir komputasional adalah jenis kemampuan pemecahan masalah menggunakan logika berpikir yang dilakukan siswa dengan langkah yang teratur. Kemampuan kognitif tersebut menjadi salah satu keterampilan penting dalam mendukung siswa terhadap konsep matematika. Namun keunggulan dari pemikiran komputasional, nampaknya tidak terlalu diperhatikan oleh Pendidikan, khususnya di Indonesia. Hal ini karena pendekatan pembelajaran kurang menekankan pada aspek positif yang dapat memberikan peningkatan siswa dalam berpikir secara komputasional. Akibatnya secara rata-rata kemampuan berpikir komputasional siswa menjadi rendah. Jenis penelitian ini menggunakan metode eksperimen jenis pretest-posttest control group design. Populasi yang terlibat ialah siswa kelas XII MA Daruttauhid Malang yang terdiri atas sebanyak 22 siswa pada kelas eksperimen, dan 24 siswa kelas kontrol. Data penelitian berupa skor pretest sebelum diberikan perlakuan pembelajaran matematika realistik, dan data skor posttest. Hasil penelitian yang diperoleh, menunjukkan bahwa kemampuan berpikir komputasional siswa pada kelas eksperimen lebih tinggi dibandingkan kelas kontrol. Untuk lebih jelasnya, fakta ini diukur dengan menghitung skor N-Gain siswa pada kelas eksperimen dengan nilai 0,7 (kategori tinggi), dan skor N-Gain siswa kelas kontrol bernilai 0,5 (kategori sedang).
