Development of Lombok Culture-Based Ethnomathematics Module to Improve Mathematical Literacy of Class IV Elementary School Students

Abstract

Quick influence on the success of the teaching and learning process can be done by developing an innovation and learning tools, one of which is through modules as teaching materials. The creation of an ethnomathematics module based on Lombok culture is expected to help develop students' mathematical literacy skills. The purpose of this development research is to get feedback from users and ensure the validity of the module. The subject of this research is Majuwet Elementary School in Lombok. This type of research is Research and Development (R&D) based on the 4D research and development model. The stages carried out are the definition stage ( Define ), the planning stage ( Design ), the development stage ( Development ), and the deployment stage ( Disseminate ). Collecting data in this study using tests, questionnaires and documentation. The results showed that the Lombok culture-based ethnomathematics module was declared valid based on the validity test. The results of the data analysis of material experts obtained 0.67 results with valid categories, media experts obtained 0.80 results with valid categories, 81% small-scale trials with agreed criteria, 87% large-scale trials with strongly agreed criteria, practicality test by the teacher 76% with practical criteria. The practicality criteria and the N-gain value show that students' mathematical literacy abilities have increased after using the modules in the learning process, with a value of 0.54 in the medium category. This research produced a valid and practical module in improving students' mathematical literacy skills and effectively used in the learning process in class IV mathematics.
