Pengaruh Integrasi Aktivitas Unplugged Coding Berbasis Computational Thinking terhadap Kemampuan Berpikir Kritis Matematis Siswa SD
Downloads
Rendahnya tingkat kemampuan berpikir kritis matematis siswa sekolah dasar menunjukkan pentingnya strategi pembelajaran yang mampu mengembangkan keterampilan berpikir tingkat tinggi melalui pengalaman pembelajaran yang bermakna. Penelitian ini bertujuan menganalisis pengaruh integrasi aktivitas unplugged coding berbasis Computational Thinking terhadap kemampuan berpikir kritis matematis siswa sekolah dasar. Penelitian menggunakan pendekatan kuantitatif dengan desain Nonequivalent Control Group Design yang melibatkan 50 siswa kelas IV SDN 02 Nagri Kaler. Instrumen penelitian berupa tes uraian kemampuan berpikir kritis matematis pada materi pecahan yang telah memenuhi kriteria validitas dan reliabilitas. Data dianalisis menggunakan uji Mann–Whitney U dan Wilcoxon Signed Rank Test. Hasil penelitian menunjukkan bahwa integrasi aktivitas unplugged coding berbasis Computational Thinking berpengaruh signifikan terhadap kemampuan berpikir kritis matematis siswa (p < 0,001), dengan peningkatan kemampuan pada kelas eksperimen lebih tinggi dibandingkan kelas kontrol. Temuan ini memperluas bukti empiris mengenai implementasi aktivitas unplugged coding berbasis Computational Thinking dalam pembelajaran matematika sekolah dasar serta menegaskan efektivitasnya sebagai strategi pembelajaran untuk mengembangkan kemampuan berpikir kritis matematis siswa.
