Enhancing Mathematical Thinking Skills through Realistic Mathematics Education Assisted by an Ethnomathematics Mobile Module Rahayu, Ratri Fahma, Marizka Aulia Bintoro, Henry Suryo Murti, Alif Catur This study addresses the deficiencies in students' mathematical thinking skills. A preliminary assessment of 69 students yielded a mean score of 21.32. The study examined enhancing students' mathematical thinking skills through the Realistic Mathematics Education (RME) model, supported by the ethnomathematics mobile module. This quantitative research employs a quasi-experimental design. The researchers collected data using a mathematical thinking skills test and analyzed it through an independent sample t-test and N-gain test. The findings indicate a significant improvement in the experimental group's posttest mean score, which increased to 80.72, surpassing the control group's posttest mean score of 69.49. The results confirm a significant difference in mathematical thinking skills between students taught using the RME approach with the ethnomathematics mobile module and those instructed through traditional lectures. The pretest-posttest data for the experimental group yielded an N-gain score of 0.59, classified as moderate. The study concludes  that implementing the RME model with the ethnomathematics mobile module effectively enhances seventh-grade students' mathematical thinking skills in data presentation. The findings suggest that the ethnomathematics mobile module should be incorporated into other mathematical topics to support students' learning further.      Keywords: ethnomathematics mobile module, mathematics thinking skills, RME.
