AbstrakPenelitian ini bertujuan untuk mengembangkan teori instruksional lokal untuk mendukung pengembangan siswa pemahaman dasar tentang persentase. Penelitian desain dipilih sebagai sarana yang tepat untuk mencapai tujuan. Penelitian dilakukan di Pusri Sekolah Dasar Palembang, Kelas 5 yang melibatkan 42 siswa secara total dan satu guru kelas. Pendidikan Matematika Realistik Indonesia (PMRI) yang diadaptasi dari Realistic Mathematics Education (RME) sengaja dipilih sebagai pendekatan dalam proses belajar mengajar. Keakuratan ini mengungkapkan bahwa bar persentase yang disajikan sebagai model dalam pembelajaran membantu siswa untuk memahami persentase. Siswa menggunakannya sebagai alat untuk penalaran dan juga sebagai alat untuk menghitung. Itu juga membantu mereka untuk menyampaikan pemikiran mereka kepada orang lain. Untuk beberapa siswa yang biasanya menggunakan cara formal untuk menyelesaikan masalah persentase, temukan kotak persentase sebagai cara lain untuk membuktikan hasilnya. AbstractThis present study is aimed to develop a local instructional theory to support students development of basic understanding of percentages. Design research was chosen as an appropriate mean to achieve the goal. The study was conducted in Pusri Primary School Palembang, Grade 5 involving 42 students in total and one classroom teacher. Pendidikan Matematika Realistik Indonesia (PMRI) which was adapted from Realistic Mathematics Education (RME) was deliberately chosen as an approach in the teaching and learning process. This stuidy revealed that a percentage bar which is served as a model in learning helped students to understand percentages. Students used it as a tool for reasoning and also as a tool for calculating. It also helped them to represent the percents stated and to communicate their thoughts to others. For some students who usually utilized the formal way to solve percentage problems, found the bar as another way to prove the result.

Intersection and union concepts are crucial part of operation in sets, especially in solving word problems and creating the venn diagram. In fact, not a few students do fallacies in representing sets word problems into a sets operation, so they do mistakes in solving the problems. This study aims to investigate students’ thinking in learning intersection and union concept, specifically by using colored cards. The learning is designed under Realistic Mathematics Education (RME) approach and the principle used is emergent modeling. The method used in this study is design research. The subjects of this study is 25 students of the 7th grade junior high school, in which five of them were the focused group. The main findings in this study are description of students’ thinking while learning union and intersection using colored cards in the class, and any kinds of students’ ‘diagram venn’models. Keywords: design research, intersection, realistic mathematics education, union, venn diagram

The process of teaching and learning mathematics in elementary schools is generally presented in an abstract form, learning is dominated by lectures, exercises, and question and answer methods so that students become passive and find it difficult to understand the material.  This study aims to determine the level of activity and student learning outcomes in mathematics class VA students of SDN 2 Kotagajah.  So that mathematics learning activities can be felt meaningful and produce activity and learning outcomes as well as learning objectives to be achieved properly is to apply the approach of realistic mathematics education (RME).  Realistic Mathematics Education (RME) is an approach that emphasizes the conceptualization of teaching and has a tendency for students to become active participants in the teaching and learning process.  This research is a classroom action research with data analysis in the form of qualitative and quantitative analysis using test data collection tools, observation, and documentation.  This study concludes that there is a relationship between student activity and learning outcomes and the use of successful methods to achieve the desired targets.  The average percentage of student activity in the first cycle was 67% and remembering as much as 11% and in the second cycle was 78%.  The percentage of completeness of learning outcomes reached 52% and 76% in cycle II.  So, there was an increase in learning outcomes from cycle I to cycle II, which was 24%.

Innovative Learning

Learning mathematics has a significant contribution to the students’ daily activities, one of which is on social arithmetic topic. The implementation of social arithmetic, in general, is mostly found in buying-selling and banking activities. However, students still find difficulties in understanding this topic. It is because the teaching and learning activities still use a conventional approach, which restricts the students to imagine how it is implemented in daily life. Therefore, this paper aims to describe the innovative learning activities of social arithmetic among junior high school students using the Realistic Mathematics Education (RME) approach. This research was conducted in three meetings, and the researcher acted as the teacher in the class. The results showed that the innovative learning of social arithmetic using the RME approach and word problems could improve the students’ learning outcomes with an average score of 81.92% and 92.59% of the total of students scored above passing grade.
