Meningkatkan Pemahaman Bangun Ruang melalui Media Augmented Reality di Kelas V

Abstract

This research is motivated by the low understanding of fifth grade students on the material of spatial figures, which is caused by the limitations of conventional learning media in facilitating three-dimensional spatial visualization. Students have difficulty imagining the shape of the spatial figure only from two-dimensional images in textbooks, so the learning process becomes less meaningful. To overcome this problem, this study aims to improve the understanding of the concept of spatial figures through the use of Augmented Reality (AR) media. The research was conducted in the form of Classroom Action Research (CAR) with the Kemmis and McTaggart model, which was implemented in two cycles at Kebonsari 2 Elementary School, Malang City with 28 fifth grade students as subjects. Data were collected through written tests (pretest and posttest), observation, and documentation, and analyzed quantitatively and qualitatively. The results of the study showed a significant increase in student understanding, indicated by an increase in the average score from 64.61 (pretest) to 78.21 (cycle I), and 88.61 (cycle II). In addition, the use of AR media encouraged active student involvement, strengthened visualization skills, and created an interactive and
enjoyable learning atmosphere. Thus, AR media has proven effective in improving the quality of mathematics learning in elementary school on spatial geometry.
