Abstract

This study aims to develop mathematics teaching materials using the Realistic Mathematics Education (RME) model based on ethnomathematics to improve elementary school students’ numeracy literacy skills. The research method used is Research and Development (R&D) with the ADDIE model. The research subjects were fourth-grade students at SDN 067775 Medan Johor. The results show that the developed mathematics teaching materials using the ethnomathematics-based RME model achieved a very valid category, with average validation scores of 86.60% from teaching material experts, 88.30% from teaching module experts, and 89.06% from content experts. The numeracy literacy test obtained a validity score of 81.81%, resulting in an overall average validity score of 86.44%, categorized as very valid. The teaching materials also met the effectiveness criteria, with a student response questionnaire result of 94% and student absorption rate of 96.42%, yielding an average effectiveness score of 95.21%. Therefore, the ethnomathematics-based teaching materials using the RME model are considered effective. Furthermore, the practicality criterion was fulfilled, as shown by the lesson implementation observation sheet, which scored 93.54%, categorized as well-implemented. In conclusion, the developed teaching materials are valid, effective, and practical for use in learning and can improve students' numeracy literacy skills by 28%.

Abstract

This research aims to develop ethnomathematics-based Student Worksheets (LKPD) on flat shapes using the Realistic Mathematics Education (RME) model to increase the learning interest of fourth-grade elementary school students. The research method used is Research and Development, with the subjects being fourth-grade students of SD Negeri 064955 and the object being the developed LKPD. The results of trials on 20 students showed an average score of 3.75, which is categorized as very practical, with students feeling happy because the material is presented in familiar cultural stories and fun activities. The responses of teachers and students to the development of this LKPD were very positive, the validity level of the LKPD was very high, and it was effective in increasing students' learning interest, so this LKPD is suitable for use as an innovative learning medium in elementary schools.
