Abstract

Instruction on Earth's structure in junior high schools still faces challenges in visualizing abstract objects that cannot be directly observed. The use of textbooks and PowerPoint presentations with two-dimensional visuals has not fully enabled students to form a concrete understanding of the composition and characteristics of Earth's layers. This study aimed to develop and evaluate the validity, practicality, and effectiveness of Augmented Reality-based learning media regarding Earth's structure for 7th-grade students at SMPN 34 Padang. The study employed the Research and Development (R&D) method using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Validation involved one subject matter expert and two media experts, while field testing involved 31 students from class VII G using a one-group pretest-posttest design. Data were analyzed using the N-Gain score. The results showed validity scores of 95% from the subject matter expert and 98.5% and 96.92% from the media experts, along with a practicality score of 4.68, indicating the media was highly valid and highly practical. The average pretest score of 49.84 rose to 91.29 in the posttest, yielding an N-Gain of 82.64% (high category). These results indicate an improvement in learning outcomes following the use of the media, although a causal relationship could not be definitively proven without a control group. Overall, the developed media was valid and practical, and demonstrated improved learning outcomes during the trial
