Kemampuan berpikir kritis penting dimiliki mahasiswa calon guru matematika. Fakta menunjukkan bahwa perhatian pada cara berpikir kritis mahasiswa masih kurang. Hal ini berdampak pada rendahnya kemampuan berpikir kritis. Penelitian bertujuan menganalisis bagaimana cara berpikir kritis mahasiswa calon guru matematika dalam menyelesaikan permasalahan yang diberikan. Desain yang digunakan yaitu deskriptif kualitatif, dengan partisipan 16 mahasiswa semester III program studi pendidikan matematika di salah satu perguruan tinggi swasta di Indonesia. Pengumpulan data dilakukan melalui uji instrumen berbentuk tes uraian kemampuan berpikir kritis matematis. Analisis data dilakukan dalam tiga langkah yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukan bahwa terdapat beberapa cara berpikir kritis yang dilakukan oleh partisipan dalam menyelesaikan suatu permasalahan. Pada bagian membuktikan, variasi cara berpikir yang dilakukan partisipan terdiri dari tiga cara; pada bagian menggeneralisasi terdiri dari dua cara; pada bagian mempertimbangkan alternatif jawaban terdiri dari tiga cara; dan pada bagian memecahkan masalah terdiri dari tiga cara. Cara berpikir kritis tersebut diharapkan menjadi titik awal yang perlu diperhatikan untuk meningkatkan kemampuan berpikir kritis.
Critical thinking skills are important for pre-service mathematics teachers. The facts show that attention to pre-service mathematics teachers ' critical thinking is still lacking. It has an impact on the low ability to think critically. This study aims to analyze how pre-service mathematics teachers think critically about mathematics in solving the problems given. The design used is descriptive qualitative, with 16 third semester students participating in the mathematics education study program at a private university in Indonesia. Data collected through an instrument test in the form of a description test of mathematical critical thinking skills. Data analysis was in three steps, reduction, data presentation, and concluding. The results show that there are several ways of thinking critically by the participants in solving a problem. In the proving section, the variation in the way participants think consists of three ways; in the generalization, section consists of two ways; in the section considering alternative answers consists of three ways, and in the problem-solving section consists of three ways. This critical thinking is expected to be a starting point that needs to be considered to improve critical thinking skills.
