Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan berpikir kritis siswa dalam pembelajaran IPA di tingkat sekolah dasar, yang disebabkan oleh penerapan metode pembelajaran konvensional yang belum optimal dalam menumbuhkan kemampuan berpikir kritis siswa. Tujuan dari penelitian ini adalah untuk menganalisis peningkatan serta pengaruh model problem based learning (PBL) dengan bantuan media augmented reality terhadap kemampuan berpikir kritis siswa sekolah dasar. Metode yang digunakan adalah kuantitatif dengan pendekatan quasi eksperimen, yang melibatkan dua kelompok yaitu kelas eksperimen dan kelas kontrol yang masing-masing terdiri dari 29 siswa. Instrumen yang digunakan adalah tes kemampuan berpikir kritis, dengan 5 indikator diantaranya klarifikasi, dasar pengambilan keputusan atau dukungan, inferensi, penjelasan lebih lanjut, serta strategi dan taktik. Hasil penelitian menunjukkan adanya perbedaan signifikan antara kelas eksperimen dan kelas kontrol setelah perlakuan (Sig.= < 0,05). Rata-rata skor N-Gain pada kelas eksperimen sebesar 0,58 termasuk kedalam kategori sedang, serta uji regresi menunjukkan hubungan yang positif antara penerapan model problem based learning (PBL) dengan media augmented reality terhadap peningkatan kemampuan berpikir kritis siswa (R = 0,721). Dengan demikian dapat disimpulkan bahwa kemampuan berpikir kritis siswa mengalami peningkatan setelah diberikan perlakuan pada kelas eksperimen dengan model problem based learning (PBL), serta terdapat pengaruh pada model problem based learning (PBL) terhadap kemampuan berpikir kritis siswa. ----- This study was motivated by the low critical thinking skills of elementary school students in science learning, which is attributed to the use of conventional teaching methods that are not yet effective in fostering critical thinking abilities.the purpose of this research is to analyze the improvement and the effect of the Problem Based Learning (PBL) model assisted by Augmented Reality media on the critical thinking skills of elementary students. The study employed aquantitativemethod with a quasi-experimental approach involving teo groups, namely the experimental class and the control class, eachconsisting of 29 students. The instrument used was a critical thinking skills test, which included five indicator: clarification, basis for decision-making or support, inference, further explanation, and strategies and tacties. The result indicated a significant difference between the experimental and control groups after the treatment (Sig. = < 0,005). The average N-Gain score in the experimental class was 0.58, categorized as moderate, and the regression analysis showed a positive relationship between the implementation of the problem based learning model with augmented reality media and the improvement of students critical thinking skills (R=0,721). Therefore,it can be concluded that students critical thinking skills improved after being taught using the problem based learning model in the experimental class, and that the problem based learning model had a significant effect on enhancing students critical thinking abilities.
