Development of an E-Module Based on Geogebra Augmented Reality Technology for Learning Spatial Geometry

The main characteristic of 21st century learning is the use of technology as a learning tool, and e-modules are technologybased learning media. In learning so far, images/shapes of spatial shapes are only abstract or 2D. Integration of Augmented Reality technology with GeoGebra is a technique of combining real objects with virtual objects in two or three dimensions which are projected simultaneously into the real environment. This development research aims to produce an e-module based on Augmented Reality GeoGebra Geometry Material for Building Spaces that is valid, practical and effective. This research method is R&D with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). This research was conducted at Adventist Middle School 5 Kairagi Weru Class VIII, Even semester of the 2023/2024 academic year. The research instruments used were interviews, observations, questionnaires and learning outcomes tests. The data analysis technique used is descriptive statistics. Based on the research results, the validity test results of the GeoGebra Augmented Reality e-module material on geometric shapes are in the very valid category with a percentage of 90.83%. The results of the practicality assessment based on observation analysis data on the implementation of learning emodules are in the very practical category with an average percentage of 93.17%, based on the analysis of teacher response questionnaires they are in the very practical category with a percentage of 89.29% and based on the analysis of student response questionnaires is in the very practical category with a percentage of 91.50%. The results of the effectiveness test are in the very effective category with a percentage of 85.71%. So it can be concluded that the Geogebra Augmented Reality E-Module Geometry Material for Building Spaces meets the criteria of Valid, Practical and Effective.
