%A Asmara Adi %X This study is a pretest-posttest quasi experimental control group design conducted to investigate the role of model -eliciting activities approach, school cluster, and prior mathematics ability on student’s mathematical communication and mathematical disposition. The study involved 74 tenth grade students from senior high school in Bengkulu. The instrumen were a mathematical communication test , and a mathematical disposition scale. The data were analyzed by using two paths Annova, Scheffe test, and t-test. The study found that model-eliciting activities approach have influence toward attaining and gaining mathematical communication and disposition. %K model-eliciting activities approach, mathematical communication, mathematical disposition. %L UNY11516 %T IMPROVING SENIOR HIGH SCHOOL STUDENT’S MATHEMATICAL COMMUNICATION ABILITIES AND MATHEMATICAL DISPOSITION BY USING MODEL-ELICITING ACTIVITIES %J Proceeding of International Conference On Research, Implementation And Education Of Mathematics And Sciences 2014 %D 2014 %I Yogyakarta State University
