Abstract
Penelitian ini dilatarbelakangi oleh rendahnya kemampuan berpikir kritis dan rasa percaya diri siswa dalam pelajaran matematika yang diakibatkan dari penerapan pembelajaran konvensional. Salah satu model pembelajaran yang dapat diterapkan untuk meningkatkan kemampuan berpikir kritis dan rasa percaya diri siswa adalah pembelajaran berbasis Mathematical Argumentation. Tujuan penelitian ini untuk menganalisis pengaruh pembelajaran berbasis Mathematical Argumentation terhadap kemampuan berpikir kritis dan rasa percaya diri siswa. Penelitian ini menggunakan metode kuasi eksperimen dengan desain nonequivalent control groups. Penelitian dilakukan pada 58 siswa kelas IV di salah satu Sekolah Dasar di Kabupaten Kuningan. Instrumen yang digunakan terdiri dari instrumen tes kemampuan berpikir kritis dan angket skala sikap percaya diri. Analisis kuantitatif dilakukan terhadap rata-rata nilai pretes dan postes kemampuan berpikir kritis dengan menggunakan uji Mann-Whitney sedangkan rata-rata N-gain kemampuan berpikir kritis, skor pretes, skor postes, dan N-gain skala sikap percaya diri menggunakan Uji-t. Hasil penelitian menunjukkan bahwa pembelajaran berbasis Mathematical Argumentation dapat meningkatkan kemampuan berpikir kritis matematis. Hal ini karena pembelajaran berbasis Mathematical Argumentation mendukung siswa melakukan penalaran, eksplorasi contoh, mengidentifikasi data pendukung, dan menilai kebenaran dari suatu pernyataan matematika. Peningkatan rasa percaya diri siswa yang mendapatkan pembelajaran berbasis Mathematical Argumentation lebih baik dibandingkan dengan siswa yang mendapatkan pembelajaran konvensional. Hal ini karena dukungan interaksi kelompok dan motivasi belajar. Pembelajaran berbasis Mathematical Argumentation dapat menjadi alternatif model pembelajaran yang dapat digunakan di sekolah dasar karena dapat meningkatkan kemampuan berpikir kritis dan rasa percaya diri.;---This study is grounded by the low ability of critical thinking and self-confidence of students in the mathematics lessons caused by the implementation of conventional learning. A learning model that can be implemented to improve students' critical thinking and self-confidence is Mathematical Argumentation based learning. The purpose of this study is to analyze the influence of Mathematical Argumentation based learning on students' critical thinking ability and self-confidence. This study used quasi experimental method with nonequivalent control groups design. The study was conducted on 58 fourth-grade students in a primary school in Kuningan Regency. The instrument consisted of test and questionnaire of attitude scale. Quantitative analysis was performed on the mean of pretest and posttest score using Mann-Whitney test while the mean of N-gain critical thinking ability, mean of pretest, mean of posttest, and N-gain of self-confidence scores between the two sample groups using t-test. The results showed that Mathematical Argumentation based learning can improve students’ critical thinking ability. This is because Mathematical Argumentation based learning encourage students doing reasoning, exploring examples, identifying the supporting data, and assessing the validity of a mathematical statement. Self-confidence gain of students who obtained Mathematical Argumentation based learning is better than students who obtained conventional learning. It is due to the support of group interaction and motivation in learning. Mathematical Argumentation based learning can be an alternative model of instruction that is used in Primary School because it can improve the ability of critical thinking and self-confidence.
