Abstract

ABSTRAK Penelitian ini dilatar belakangi oleh masih rendahnya kemampuan pemahaman konsep matematika peserta didik kelas IV SD Negeri 1 Padang Manis Tanggamus yang disebabkan oleh pembelajaran yang masih berpusat pada guru sehingga peserta didik kurang aktif dan cenderung menghafal rumus tanpa memahami konsep yang dipelajari. Salah satu upaya yang dapat dilakukan untuk meningkatkan pemahaman konsep matematika adalah dengan menerapkan model Problem Based Learning yang didukung oleh media Augmented Reality. Penelitian ini bertujuan untuk mengetahui pengaruh model Problem Based Learning berbantuan media Augmented Reality terhadap pemahaman konsep matematika peserta didik kelas IV SD Negeri 1 Padang Manis. Metode penelitian yang digunakan adalah penelitian kuantitatif dengan pendekatan quasi eksperimen design menggunakan desain Nonequivalent Control Group Design. Subjek penelitian terdiri atas dua kelas, yaitu kelas IV A sebagai kelas eksperimen yang memperoleh pembelajaran menggunakan model pembelajaran Problem Based Learning berbantuan Media Augmented Reality dan kelas IV B sebagai kelas kontrol yang memperoleh pembelajaran menggunakan model pembelajaran Project Based Learning. Teknik pengambilan sampel menggunakan random cluster sampling. Instrumen penelitian berupa tes pilihan ganda yang diberikan dalam bentuk pretest dan posttest untuk mengukur kemampuan pemahaman konsep matematika siswa. Hasil penelitian menunjukkan bahwa terdapat pengaruh yang signifikan dari penerapan model pembelajaran Problem Based Learning berbantuan Media Augmented Reality terhadap pemahaman konsep matematika siswa. Hal ini dibuktikan melalui hasil uji hipotesis yang memperoleh nilai signifikansi sebesar 0,000 < 0,05, sehingga H₀ ditolak dan H₁ diterima. Dengan demikian, dapat disimpulkan bahwa model pembelajaran Problem Based Learning berbantuan media Augmented Reality berpengaruh terhadap pemahaman konsep matematika siswa kelas IV SDN 1 Padang Manis Tanggamus dan memberikan hasil yang lebih baik dibandingkan dengan model pembelajaran Project Based Learning. ABSTRACK This study is motivated by the still low ability of fourth-grade students at SD Negeri 1 Padang Manis Tanggamus to understand math concepts, which is caused by teacher-centered learning so that students are less active and tend to memorize formulas without understanding the concepts being learned. One effort to improve students' understanding of math concepts is by applying the Problem Based Learning model supported by Augmented Reality media. This study aims to find out the effect of the Problem Based Learning model assisted by Augmented Reality media on the understanding of math concepts of fourth-grade students at SD Negeri 1 Padang Manis. The research method used is quantitative research with a quasiexperimental approach using a Nonequivalent Control Group Design. The research subjects consist of two classes: class IV A as the experimental class that received learning using the Problem-Based Learning model assisted by Augmented Reality Media, and class IV B as the control class that received learning using the Project-Based Learning model. The sampling technique used is random cluster sampling. The research instrument is a multiple-choice test given in the form of a pretest and posttest to measure students' understanding of math concepts. The research results show that there is a significant effect of applying the Problem Based Learning model assisted by Augmented Reality Media on students' understanding of mathematical concepts. This is proven by the hypothesis test results, which obtained a significance value of 0.000 < 0.05, so H₀ is rejected and H₁ is accepted. Therefore, it can be concluded that the Problem Based Learning model assisted by Augmented Reality media affects the understanding of mathematical concepts of fourth-grade students at SDN 1 Padang Manis Tanggamus and produces better results compared to the Project Based Learning model.
