Abstract
Kemampuan berpikir kritis merupakan salah satu kompetensi penting abad ke-21, namun masih tergolong rendah dalam pembelajaran IPA di sekolah dasar. Upaya peningkatan dapat dilakukan melalui penerapan model Problem Based Learning (PBL) berbantuan media Augmented Reality yang mendorong keterlibatan aktif siswa. Penelitian ini bertujuan untuk: (1) Mengetahui peningkatan kemampuan berpikir kritis IPA siswa yang mendapatkan model PBL berbantuan Augmented Reality dibandingkan Discovery Learning berbantuan PowerPoint, dan (2) Mengetahui pengaruh penerapan model PBL berbantuan Augmented Reality terhadap peningkatan kemampuan berpikir kritis siswa. Metode yang digunakan adalah quasi experiment dengan desain non-equivalent control group. Subjek penelitian adalah siswa kelas IV SDN Purwamekar. Teknik pengumpulan data menggunakan tes dan dokumentasi. Hasil menunjukkan bahwa: (1) Peningkatan kemampuan berpikir kritis IPA siswa melalui model PBL berbantuan Augmented Reality lebih baik (77,31%) dibandingkan model Discovery Learning berbantuan Powerpoint (66,98%), dan (2) Pengaruh dari model PBL berbantuan Augmented Reality sebesar 54,70%. Dengan demikian, model tersebut efektif meningkatkan kemampuan berpikir kritis IPA siswa SD. Critical thinking ability is one of the important competencies of the 21st century, but it is still relatively low in science learning in elementary schools. Efforts to improve it can be done through the application of the Problem Based Learning (PBL) model assisted by Augmented Reality media which encourages active student involvement. This study aims to: (1) Determine the increase in critical thinking skills in science of students who receive the PBL model assisted by Augmented Reality compared to Discovery Learning assisted by PowerPoint, and (2) Determine the effect of the application of the PBL model assisted by Augmented Reality on improving students' critical thinking skills. The method used is a quasi experiment with a non-equivalent control group design. The subjects of the study were grade IV students of SDN Purwamekar. Data collection techniques used tests and documentation. The results showed that: (1) The increase in students' critical thinking skills in science through the PBL model assisted by Augmented Reality was better (77.31%) than the Discovery Learning model assisted by Powerpoint (66.98%), and (2) The effect of the PBL model assisted by Augmented Reality was 54.70%. Thus, the model is effective in improving students' critical thinking skills in science.
