Abstract

This study aimed to develop and evaluate Augmented Reality (AR)-based learning media for the Earth and Solar System topics in middle school science education. Using the Research and Development (R&D) approach with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation), the study developed AR media designed to enhance student understanding of complex scientific concepts. The effectiveness of the AR media was assessed through Aiken's V validation, practicality tests from teachers and students, and pre-test and post-test evaluations. The results showed that the AR media significantly improved student engagement, understanding, and academic performance. Aiken's V validation scores for usability, information, and interaction quality were above 0.8, indicating that the media was valid and effective. The practicality test revealed that teachers rated the media highly (93% usability), while students gave slightly lower ratings (81% usability). The N-gain score from pre-test and post-test evaluations showed a 56.2% improvement in students' knowledge, confirming the positive impact of the AR media on learning outcomes. Despite the challenges with usability for some students, the overall feedback supports AR's potential in enhancing science education, especially in rural settings. The study recommends further research to overcome usability challenges and optimize AR's classroom integration.

Abstract

Low student learning outcomes in Chemistry at SMAN 1 V Koto Kampung Dalam, Padang Pariaman Regency, are caused by teachers' limitations in utilizing interactive digital learning media. Learning is still dominated by conventional methods, while students need attractive visual and digital media to understand abstract Chemistry concepts. This study aims to develop and test the validity, practicality, and effectiveness of a Google Sites-based Learning Management System in Chemistry learning. The method used is Research and Development (R&D) with the ADDIE model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The research subjects consisted of 30 grade XI students selected through random sampling from a total population of 92 students. The research instruments included an expert validation sheet, a teacher and student practicality questionnaire, and a learning outcome test (pre-test–post-test). The results showed that the Google Sites-based learning management system was rated "Highly Valid" by subject matter and media experts and "Highly Practical" according to teacher and student responses. The effectiveness test using the Wilcoxon Signed-Rank Test produced a significant value of 0.000 (<0.05) and an N-Gain score of 0.83 in the "Effective" category. Future work is recommended to integrate this learning management system with learning analytics and mobile learning features to expand its effectiveness in sustainable digital learning.
