<![CDATA[During the learning process science, the lack of teachers in implementing effective learning models and media to support learning objectives leads to low student motivation. This study aims to analyze the impact of using the Team Games Tournament (TGT) learning model, incorporating a solar system monopoly game, on the learning motivation of sixth-grade science students in elementary school. The study follows the ADDIE development model. Data collection methods include interviews, validation questionnaires from media and material experts, and response questionnaires from students and teachers. A limited trial was conducted with 6 students to assess media practicality, while a broader trial involved 20 students and 1 teacher to evaluate media effectiveness. Student learning outcomes were measured using pre-tests and post-tests. Pre-test scores were collected before the intervention, while post-test scores were gathered afterward. The difference in scores was analyzed using a paired t-test, revealing a Sig. (2-tailed) value of 0.005. This result indicates that the null hypothesis (Ho) is rejected, and the alternative hypothesis (Ha) is accepted, demonstrating a significant difference between pre-test and post-test scores. This finding suggests that the solar system monopoly media positively impacts student learning motivation. Consequently, the study concludes that the solar system monopoly media is both valid and practical for use in enhancing student motivation in learning science.]]>
