Abstract

This study aims to analyze the spatial ability of students using GeoGebra in solving students' spatial ability problems in the spatial geometry course. The research method used uses a descriptive qualitative method. The instrument used is a spatial ability test of spatial geometry which is arranged based on spatial ability indicators, namely visualization, spatial perception, mental rotation, spatial relation, and spatial orientation. The research subjects used were all students of the Mathematics Department of the Faculty of Tarbiyah and Teacher Training (FITK) semester 3 classes A and B of the State Islamic University of Cyber Syekh Nurjati Cirebon (UIN SSC) totaling 49 students. The results of this study show that the spatial ability of students using GeoGebra in the spatial geometry course is very good with an overall score of 86.5 and a score per indicator, in the visualization indicator of 100, spatial perception of 92.65, mental rotation of 94.28, spatial relation of 53.06, and spatial orientation of 92.65.

Abstract

This study presents the design and evaluation of marker-based augmented reality instructional media using Unity and Vuforia to support polyhedra learning in junior high school geometry. The development followed the 4D model and was grounded in a five-phase learning trajectory consisting of exploration, manipulation, analysis, application, and reflection. The AR media features interactive 3D polyhedron models, net unfolding animation, and formula overlays, each activated through printed markers. The design was informed by students’ learning needs, particularly difficulties in visualizing shapes, distinguishing surface area from volume, and applying geometric formulas correctly. Expert validation using Aiken’s V confirmed strong instructional alignment. Student perception data, classroom observations, and teacher interviews indicated that the media enhanced spatial reasoning, improved engagement, and encouraged verbal mathematical discourse. The findings support the integration of AR into structured pedagogical sequences and demonstrate its potential to improve geometry instruction in diverse classroom settings.
