Abstract

Pengembangan kemampuan berpikir kritis bertujuan untuk mencapai pemahaman yang lebih mendalam dan pembentukan konsep matematika. Namun, seringkali kita menemukan bahwa kemampuan berpikir kritis siswa masih kurang, yang berdampak pada kualitas pembelajaran matematika. Penelitian ini bertujuan untuk mengetahui sejauh mana kemampuan berpikir kritis siswa kelas VIII di SMP 150 Jakarta dalam konteks materi kubus dan balok. Pendekatan yang digunakan dalam penelitian ini adalah deskriptif kualitatif. Penelitian ini melibatkan 32 siswa dari kelas VIII-G dan data dikumpulkan melalui analisis respon tes siswa dan wawancara. Dalam penelitian ini, peneliti mengacu pada empat indikator kemampuan berpikir kritis seperti yang dijelaskan oleh Facione: interpretasi, analisis, evaluasi, dan inferensi. Hasil analisis data respon siswa menunjukkan bahwa nilai rata-rata siswa kelas VIII-G SMP 150 Jakarta adalah 41,5, yang termasuk dalam kategori rendah.

Kesimpulannya, tingkat kemampuan berpikir kritis siswa kelas VIII-G SMP 150 Jakarta masih sangat rendah, dan perlu adanya upaya pelatihan untuk meningkatkan kemampuan ini. / The development of critical thinking skills aims to achieve a deeper understanding and formation of mathematical concepts.and the formation of mathematical concepts. However, we often findthat students' critical thinking skills are still lacking, which has an impact on the quality of mathematics learning.quality of mathematics learning. This study aims to determine the extent to which critical thinking skills ofof grade VIII students at SMP 150 Jakarta in the context of cube and beam material.The approach used in this research is descriptive qualitative.The study involved 32 students from class VIII-G and the data were collected through the analysis of students' test responses and interviews.through analysis of student test responses and interviews.
