<![CDATA[The results of the preliminary survey conducted at SMP Negeri 5 Metro on August 19, 2025, indicate that the mathematical communication skills of most students are still classified as low. This condition highlights the need for research on the influence of the ethnomathematics-based flipped classroom learning model on the mathematical communication skills of eighth-grade students at SMP Negeri 5 Metro. This study uses a quasi-experimental method with a posttest-only control group design, involving an experimental class with ethnomathematics-based flipped classroom learning and a control class with conventional learning. Data collection techniques were carried out through mathematical communication ability tests, observation, and documentation. Data analysis was conducted through prerequisite tests such as normality and homogeneity tests, followed by hypothesis testing using the t-test. The research results showed that the average score of students in the experimental class was 89.33, higher than the control class at 78.48. The hypothesis testing showed a significance value of 0.002<0.05, so H_0 is rejected and H_1 is accepted. Based on these results, it can be concluded that there is a significant difference in mathematical communication skills between students who participate in ethnomathematics-based flipped classroom learning and those who follow conventional learning, indicating that this model is effective for use in mathematics education.
