Kualitas sumber daya manusia yang rendah dipengaruhi oleh kualitas pendidikan di Indonesia yang masih tergolong rendah, sehingga perlu diterapkan pembelajaran yang membantu siswa dalam meningkatkan kemampuan berpikirnya. Penelitian ini bertujuan mengetahui implementasi pendekatan pembelajaran STEM (Science, Technology, Engineering, and Mathematics) untuk meningkatkan kemampuan berpikir kritis siswa. Sampel penelitian ini adalah siswa kelas XI MIPA 1 dan XI MIPA 2 SMAN 13 Bandar Lampung tahun ajaran 2017/2018. Desain penelitian ini adalah The Non-Equivalent Pretest-Posttest Control Group Design. Data kemampuan berpikir kritis siswa dikumpulkan menggunakan instrumen tes kemampuan berpikir kritis. Hasil penelitian menunjukkan bahwa nilai rata-rata N-gain pada kelas eksperimen sebesar 0,63 dan kelas kontrol sebesar 0,35 dengan kategori sedang. Secara keseluruhan implementasi pendekatan pembelajaran STEM mampu meningkatkan kemampuan berpikir kritis siswa.
The low quality of human resources is influenced by the quality of education in Indonesia is still relatively low, so it needs to be applied learning that helps students improve their thinking ability. This study aims to determine the implementation of STEM learning approach to improve students' critical thinking skills. The sample of this research is the students of class XI MIPA 1 and XI MIPA 2 SMAN 13 Bandar Lampung academic year 2017/2018. The design of this study was The Non-Equivalent Pretest-Posttest Control Group Design. Students' critical thinking skills data were collected using critical critical thinking test instruments. The results showed that the average value of N-gain in the experimental class was 0.63 and control class was 0.35 in the medium category. Overall implementation of STEM learning approach can improve students' critical thinking ability.
