<![CDATA[Mathematical communication constitutes a critical competency for students navigating the demands of the 21st century; nevertheless, preliminary investigations reveal that current proficiency levels remain suboptimal. Consequently, this study aims to evaluate the efficacy of the GeoGebra-assisted SSCS model in enhancing mathematical communication skills. Employing a quantitative methodology, this research utilizes a quasi-experimental design. Data derived from student test results were systematically analyzed utilizing t-tests, z-tests, and N-Gain evaluations. The findings demonstrate that the GeoGebra-assisted SSCS model effectively promotes mathematical communication. Specifically, this efficacy is evidenced by the fulfillment of the BTA standard, a 75% mastery rate, and a higher proportion of students achieving BTA mastery relative to the PBL model. Furthermore, the experimental group exhibited superior average scores compared to the PBL model, alongside a moderate overall improvement in mathematical communication capabilities.]]>
