<![CDATA[Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan berpikir kritis setelah diterapkan Model Direct Instruction berbasis etnosains dalam pembelajaran fisika. Jenis penelitian ini adalah Quasi Experiment. Hasil penelitian menunjukkan bahwa rata-rata posttest dan N-gain kemampuan berpikir kritis yang diperoleh kelas eksperimen dengan pembelajaran Model Direct Instruction berbasis etnosains lebih tinggi daripada kelas kontrol dengan perlakuan pembelajaran konvensional. Berdasarkan hasil analisis data, kelas eksperimen dan kelas kontrol mengalami perbedaan peningkatan skor N-gain yang signifikan dengan kelas eksperimen memperoleh skor N-gain sebesar 0.73 (kategori tinggi) dan kelas kontrol memperoleh skor N-gain sebesar 0.37 (kategori sedang) sehingga dapat disimpulkan terdapat peningkatan kemampuan berpikir kritis dengan penggunaan Model Direct Instruction berbasis etnosains dalam pembelajaran fisika.Kata Kunci: Etnosains, Model Direct Instruction, Kemampuan Berpikir KritisThis research was aimed to determine the improvement of critical thinking skills after applied the model Direct Instruction with ethno-science-based learning in physics learning. This type of research was Quasi Experiment. The results of the study showed that the average posttest and N-gain critical thinking skills were obtained in the class with the model Direct Instruction with ethno-science-based learning and the class with conventional learning treatments. Based on the results of data analysis, the experimental class and the control class experienced a significant increase in the N-gain score with the experimental class obtained an N-gain score of 0.73 (high category) and the control class obtained an N-gain score of 0.37 (medium category) so it can be concluded that there are the increase in critical thinking skills using the Model Direct Instruction with ethno-science-based learning in physics learning.Keywords: Ethno-science, Direct Instruction Model, Critical Thinking Ability]]>
