The low ability of mathematical communication at SMP Negeri 1 Way Bungur, East Lampung is due to various factors, including the assumption that mathematics is complicated, a lack of curiosity about mathematics, and a lack of variation in learning models, so that students still tend to be passive. The purpose of this study was to determine the mathematical communication skills of students who use the Islamic-nuanced Indonesian Realistic Mathematics Education (PMRI) approach better than ordinary learning. The research method used is a quantitative method using the Quasi-Experimental Design method. The data collection techniques used in the study were: documentation, tests in the form of essay questions to determine the effect of the Islamic-nuanced Indonesian Realistic Mathematics Education (PMRI) approach to improve mathematical communication skills. This study indicates an increase in the mathematical communication skills of students who are given an Islamic approach to Indonesian Realistic Mathematics Education (PMRI) with ordinary learning. Increasing students' mathematical communication skills with the Islamic-nuanced Indonesian Realistic Mathematics Education (PMRI) approach is better than regular learning. So it can be concluded that the Islamic-nuanced Indonesian Realistic Mathematics Education (PMRI) approach can improve mathematical communication skills compared to ordinary learning.

ABSTRACTThis research is motivated by the fact that the ability of mathematical communication in Indonesia is low. The models and approaches used in the learning process are one of the supporting factors for learning mathematics in the classroom. This study aimed to analyze SMA 1 Namlea students' mathematical communication skills with realistic mathematics learning assisted by GeoGebra. The research method used is quasi-experimental. WHO researched SMA Negeri 1 Namlea, Buru Regency. The analysis results show that the test instrument is valid and reliable to be used for pretest and posttest. The results showed that the mathematical communication of students who received realistic mathematics learning assisted by GeoGebra was better than students who received realistic mathematics learning without GeoGebra. The results also showed that there was a positive response from students towards learning realistic mathematics with GeoGebra.KEYWORDS: Realistic Mathematics, GeoGebra & Mathematical Communication

The main problem in this study is the lack of student communication skills and the lack of RME-based teaching materials that use used goods as a learning medium. The long-term objective of the research to be carried out is to support quality improvement and development of basic and regional education policies at the local and national levels through improving the quality of Indonesia's young generation of hope. The purpose of this study was to obtain an overview of the results of the implementation of teaching materials "mathematics learning in elementary schools". The focus of this research problem is: 1) learning steps using teaching materials and 2). Barriers are felt when learning using these teaching materials. And 3). The implementation of teaching materials uses a realistic mathematics education approach in the communication skills of PGSD students with the help of teaching aids made from used materials. The method used is descriptive qualitative, this study describes the application of elementary mathematics learning teaching materials in mathematics communication of students at the PGSD Siliwangi Teacher Training College and the obstacles in implementing teaching materials.

Mathematics learning has always been a problem in the world of education in Indonesia especially in the Province of Maluku, which is a thousand island area. The geographical position of Maluku, which is an area of the archipelago, is quite extensive, affecting the quality of students in mathematics. One approach that is recommended to overcome mathematical problems of rural island-based students is realistic mathematics education (RME). The purpose of this study was to analyze the effect of RME on mathematical reasoning and communication skills in a rural context. The research design used was quasi experiment. The sample size was 130 students from several junior high schools in Central Maluku Regency. The instrument developed was in the form of problem descriptions to measure students' mathematical reasoning and communication skills. The findings prove that RME has a significant influence on students' mathematical reasoning and communication skills. Thus, RME can be recommended in improving students' mathematical reasoning and communication skills in the island-based rural context.

This research is motivated by the lack of understanding of students' mathematical concepts in mathematics which is caused by a lack of motivation to learn in students and the lack of material connection with everyday life. Mathematics learning really needs to be learned by students because Mathematics has an important purpose to meet practical needs related to the development of students' abilities to use mathematics in everyday life, such as counting which is often experienced by students and can develop the ability to calculate weight. and content. Although Mathematics is considered important to learn, not a few students feel that Mathematics is difficult to master, so it is considered boring and makes students' interest in learning in Mathematics considered low. Based on the PISA annual study survey, the Indonesian Mathematics competency has decreased from 386 points in 2015 to 379 points in 2018 with an OECD average of 489. The benefits of studying Mathematics are used to make transactions in trade. One way to make mathematics more understandable is to use the Realistic Mathematics Education (RME) approach so that students can learn more realistically. The purpose of this study was to determine the increase in students' understanding of mathematical concepts using the Realistic Mathematics Education (RME) approach and whether there were changes that occurred after the treatment using this approach. This research was conducted with quantitative research methods and the research design of One Groups Pretest-Posttest Design. The subject of this research is class IV with a total of 28 students at SDN Curugrendeng II. The instrument used is a written test with a total of 10 questions. Calculation of data processing using Microsoft Office Excel 2007 and using IBM SPSS Statistics 22 with a significance level of 0.05. The results of this study indicate that there is an increase in students' understanding of mathematical concepts with an average value of 0.691 which is included in the medium category. Thus, the understanding of mathematical concepts of students using the Realistic Mathematics Education (RME) approach changes from before the action to the final score after the action. done. And there is an effect of the Realistic Mathematics Education (RME) approach on students' understanding of mathematical concepts by showing the results of sig.(2-tailed) 0.000 <0.05, which means H_1 is accepted so that this Realistic Mathematics Education (RME) approach can be applied to learning Mathematics in Primary school.
