Abstract


This study aims to describe the improvement of the students' reasoning and critical thinking skills through dental erosion problem based learning. The samples were taken using purposive sampling technique and obtained XI MIA 3 as experiment class and XI MIA 9 as control class. The enhancement of reasoning ability and students' critical thinking skills is determined by the n-gain of reasoning ability and critical thinking skills of students tested statistically by t test. The results showed that dental erosion problem based learning can improve students' reasoning ability and critical thinking skill.

Penelitian ini bertujuan untuk mendeskripsikan peningkatan kemampuan penalaran dan keterampilan berpikir kritis siswa melalui pembelajaran berbasis masalah erosi email gigi.  Sampel penelitian diambil menggunakan teknik purposive sampling dan diperoleh kelas XI MIA 3 sebagai kelas eksperimen dan kelas XI MIA 9 sebagai kelas kontrol di SMA Negeri 2 Bandar Lampung.  Peningkatan kemampuan penalaran dan keterampilan berpikir kritis siswa ditentukan dari n-gain kemampuan penalaran dan keterampilan berpikir kritis siswa yang diuji secara statistik dengan uji t.  Hasil penelitian menunjukkan bahwa pembelajaran berbasis masalah erosi email gigi mampu meningkatkan kemampuan penalaran dan keterampilan berpikir kritis siswa.

Kata kunci : pembelajaran berbasis masalah, erosi email gigi, keterampilan berpikir kritis, kemampuan penalaran
