Abstract

This research is motivated by the importance of mathematical critical thinking skills for students, as well as the rapid development of information technology in the digital era. This study specifically aims to improve students' mathematical critical thinking skills through the application of Augmented Reality (AR)-based learning media with 3D unity that can be used in online learning and offline learning based on Initial Mathematical Ability (IMA). Augmented Reality is a technology that combines three-dimensional virtual objects into a real environment and then projects these virtual objects in real-time. While the initial mathematical ability is one of the factors that influence the learning of mathematics, the higher the initial mathematical ability of a student, the better the level of the student's mathematical critical thinking ability. This research is quantitative research (quasi-experimental), while the research subjects are students at one of Pekanbaru's state junior high schools class VII for the academic year 2022/2023, as many as 30 students who are randomly selected by the class. This research was conducted on the material of flat shapes, especially triangles and quadrilaterals. The data collection method used was a mathematical critical thinking ability test. The test result data was processed by statistical tests, including a normality test, homogeneity test and two-way ANOVA test. The results showed that the improvement of mathematical critical thinking skills of students who received learning using augmented reality media with Unity 3D was better than the improvement of mathematical critical thinking skills of students who received conventional learning based on students' initial mathematical abilities.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh alat peraga Papan Diagram terhadap prestasi belajar peserta didik SD Negeri 158 Pekanbaru. Penelitian ini merupakan penelitian eksperimen semu (Quasi Experiment) dengan desain penelitian Nonequivalent Control Group Design. Populasi dalam penelitian ini adalah seluruh peserta didik kelas VI SD Negeri 158 Pekanbaru tahun pelajaran 2024/2025. Sampel dari penelitian ini yaitu kelas VI.A sebagai kelas kontrol dan kelas VI.B sebagai kelas eksperimen, dengan jumlah peserta didik kelas kontrol sebanyak 36 peserta didik dan kelas eksperimen sebanyak 38 peserta didik. Instrumen pengumpulan data dalam penelitian ini adalah lembar Pretest  dan Posttest. Teknik pengumpulan data dilakukan dengan teknik tes. Teknik analisis data yang digunakan adalah analisis deskriptif dan analisis inferensial. . Nilai asymp.sig (2-tailed) merupakan indikasi normalitas data yang dibandingkan dengan ¬α=0,05. Apabila nilai Asymp.sig. (2-tailed) <α=0,05 maka data tersebut berdistribusi normal sedangkan apabila nilai Asymp.sig. (2-tailed) >α=0,05 maka data tersebut berdistribusi normal. Hasil penelitian menunjukkan bahwa uji Mann-Whitney U untuk data tidak berdistribusi normal dapat diperoleh nilai Asymp.Sig. untuk Posttest kelas eksperimen dan kelas kontrol lebih kecil dari 0,05 (0,048 < 0,05). Hal ini berarti  H0 ditolak, H1  diterima, sehingga terdapat perbedaan yang signifikan antara rata-rata prestasi belajar peserta didik kelas eksperimen dan kelas kontrol. Dilihat dari skor posstest diketahui peserta didik yang menggunakan alat peraga lebih tinggi dibandingkan menggunakan model konvensional, kemudian kenaikan rata-rata prestasi belajar di kelas eksperimen adalah 38,1 sedangkan kenaikan rata-rata prestasi belajar di kelas kontrol adalah 33,89. Sehingga dapat disimpulkan bahwa terdapat pengaruh alat peraga Papan Diagram (PADI) terhadap prestasi belajar peserta didik.
