Pengembangan Buku Geometri Terintegrasi Jajanan Tradisional Berbasis Augmented Reality untuk Meningkatkan Kemampuan Spasial Siswa

Abstract

Spatial ability is a ability that students must possess to understand geometry material. Students with low spatial ability will have difficulty working on geometry problems, cannot predict the construction of 3D objects when viewed from a certain point of view, and have difficulty integrating the visual part in the side of the 3D shapes. The application of Augmented Reality technology such as Assemblr Edu which is integrated with traditional snacks can be a solution to improve students' spatial abilities. This research aims to describe the process and results of developing a geometry book integrated with traditional snacks and Augmented reality to improve students’ spatial abilities with valid, practical, and effective criteria. The research employed a research and development method using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) with Implementation using the quasi-experiment method. The methods of data collection was included questionnaires and tests. The research instruments used validation sheets, student response questionnaires, readability test sheets, and spatial ability tests that had been validated. The geometry book utilized Assemblr Edu for 3D object visualization and integrated traditional snacks as a spatial representation. It was designed based on spatial ability indicators: spatial perception, spatial visualization, and mental rotation. Trials were conducted with ninth-grade students, involving experimental and control classes. Data analysis revealed the book met validity criteria of 2.84 (3 scales), practicality (81.7%), and effectiveness in improving students' spatial abilities, with the average N-Gain being 0.56 and 93.8% of students having at least moderate spatial ability. Statistical analysis indicated a significant impact of using the AR-based geometry book on students' spatial ability. Thus, the Augmented Reality integrated geometry book with traditional snacks effectively enhances students’ spatial abilities. Future research recommends exploring other applications to support geometry learning based on Augmented Reality.
