Mathematical disposition ability through realistic mathematics learning approach with an ethnomathematics of Suku Anak Dalam (RME SAD).

In mathematics, disposition is a very important component because students are accustomed to getting problems that require a positive attitude, desire, passion, and persistence to solve them. Without a good disposition, students will not be able to achieve competence or mathematical skills as expected. Based on the results of the PISA and TIMSS in Indonesia students, it is known that students have difficulty in applying mathematics to real-life situations. Therefore, a learning model is needed that can lead students to meaningful learning. Previously, preliminary research was conducted on the ethnomathematics activities of the Suku Anak Dalam (SAD) community in Jambi Province. The findings in the preliminary study were combined with the Realistic Mathematics Learning approach, hereinafter referred to as the Ethnomathematical. Realistic Mathematics Learning with an Ethnomathematics Approach of the Suku Anak Dalam (RME SAD) tested on seventh grade students of SMP Muhammadiyah Pangkalan Balai. This study examines the improvement of mathematical dispositions between students who received the RME SAD approach and students who received conventional learning, reviewed as a whole and reviewed according to the categories of high, medium and low students' initial mathematical abilities. This study is a quasi-experimental study with a nonequivalent control-group design. The data obtained were analyzed using the mean difference test, namely t-test and Mann-Whitney. The results showed that there is no difference in the mathematical disposition of students who receive RME SAD learning than students who receive conventional learning. [ABSTRACT FROM AUTHOR]
