Abstract

This study aims to develop teaching materials using the RME model to improve students' mathematical literacy in the material of whole numbers in grade V of SDN 054890 Tanjung Baru. This study is a development research (Research and Development) using the ADDIE development procedure consisting of 5 stages. The instrument used to collect data is a questionnaire given to several expert validators, namely expert validators of teaching materials, expert validators of materials, teacher responses and student responses. The validity score obtained from the expert validator of teaching materials is 91 with the category "Very Valid". The validity score obtained from the expert validator of materials is 95 with the category "Very Valid". The practicality score obtained from the Teacher's Response is 94.4 with the category "Very Practical". The practicality score obtained from the student's response is 100 with the category "Very Practical". The effectiveness score obtained from the implementation results is 80.71. From the assessment above, it can be said that the teaching materials using the RME model to improve the mathematical literacy skills of grade IV elementary school students that were developed are "Very Suitable" for use in the learning process.

Abstract

The research conducted aims to develop ethnomathematics teaching materials using the RME model to improve the learning outcomes of fourth grade students of SDN 13 Tambun Sungkean and to determine the validity, practicality and effectiveness of the developed teaching materials. In this study, the researcher used the ADDIE development procedure consisting of 5 stages. The instrument used to determine the validity, practicality and effectiveness of ethnomathematics teaching materials using the RME model to improve the learning outcomes of fourth grade students of SDN 13 Tambun Sungkean, namely a questionnaire. The validity of ethnomathematics teaching materials using the RME model of fraction material developed obtained a percentage of 90% with the criteria of "Very Valid" from the expert validator of teaching materials and obtained a percentage of 92.94% with the criteria of "Very Valid" from the expert validator of material. The practicality of the developed teaching materials was validated by the fourth grade teacher of SDN 13 Tambun Sungkean. From the validation carried out, the maximum percentage was obtained, namely 100% with the category of "Very Practical". The effectiveness of ethnomathematics teaching materials using the RME model of fraction material developed was assessed using a student response questionnaire. From the validation, a percentage of 100% was obtained with the criteria "Very effective".
