<![CDATA[This research was motivated by the lack of innovative learning media used in teaching the volume of cubes and cuboids, causing students to experience difficulties in understanding abstract geometric concepts. This study aimed to develop an Augmented Reality-based Student Worksheet on the topic of cube and cuboid volume for fifth grade elementary school students that is valid, practical, and effective. This research employed the Research and Development (R&D) method using the ADDIE development model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The study was conducted at SD Negeri 21 Palembang. Data were collected through questionnaires, tests, and documentation. The results showed that the Augmented Reality-based Student Worksheet obtained a validation score of 94%, categorized as “Very Valid.” The practicality test results showed percentages of 94.3% in the one-to-one stage and 92.2% in the small group stage, both categorized as “Very Practical.” The effectiveness test result reached 90%, categorized as “Very Effective.” Based on these findings, the developed Augmented Reality-based Student Worksheet was declared valid, practical, and effective for use in mathematics learning in elementary school.]]>
