The innovation of education is an important point of Pendidikan Matematika Realistik Indonesia (PMRI), one of them through traditional dance as a context of national cultural. Dance that collaborated with concept of mathematics, it is called Math Traditional Dance. This research aims to produce learning line (specific) the material of reflection and symmetry. The research method used is design research that consisted of preparing for the experiments, teaching experiments, and retrospective analysis. Data collected through observation, interviews, documentation and field notes. This research was conducted with 22 students in MIN 2 Palembang. From the try out that is obtained from the formal to the informal learning described in the learning process, so that support learning process of mirroring and symmetry for the students in grade four in elementary school.

Learning about decimals is an important part in mathematics. However at the same time, decimals are known as the  abstract numbers for students. Mostly in Indonesia, decimal is taught only as another notation for fractions or percentages. There are no meaningful references  for  them  such as  the  use of  concrete  situations. This study aimed at investigating one situation that enables students to learn about decimals in a meaningful way,  i.e.  measurement  activities.  Design research was chosen to reach the research goal. Realistic Mathematics Education (RME) underlies  the design  of  context and activities. Our findings are that the students could discover decimals and  get meaningful situation from it. Measurement activities can promote the students’ notion of decimals which, then, provoke the students’ thinking into the idea of using number line as a model for placing the magnitude of decimals. Based on these findings, it is recommended that RME be implemented as an approach of teaching and learning decimals.Keywords: decimals, Realistic Mathematics Education (RME), number line, design research. DOI: http://dx.doi.org/10.22342/jme.2.2.750.215-230

Understanding of measuring time has difficulty for children because it is intangible. Standar units often use directly by teacher for learning time measurement. Many researches involved game in designing learning material to facilitate fun and meaningful learning for children. For this reason, learning of time measurement that connect with children's daily experience was designed. The context of this research was traditional gasing game. The study is situated in implementation of Indonesian version of Realistic Mathematics Education, labeled as PMRI. This research aimed acquire learning trajectory of time measurement using traditional gasing game for the third grader of primary school by describing students' progress in learning. Design research methodology comprising preparing for the experiment, teaching experiment, and retrospective analysis was used. The research was conducted in SD (Sekolah Dasar) Pusri (Pupuk Sriwijaya) Palembang as one of PMRI (Pendidikan Matematika Realistik Indonesia) school. The result of the teaching experiment showed that learning design could foster students to experience reinvention of time measurement historically. It stimulated students to emerge their sense of time, measure time using non standar unit, understand the concept of standard unit, and measure time using standar unit. Students' strategies that were emerged showed students' progress through situation and problems that were provided by traditional gasing game.

Several previous researches showed that students had difficulty in understanding the basic concept of multiplication. Students are more likely to be introduced by using formula without involving the concept itself. This underlies the researcher to design a learning trajectory of learning multiplication using Permainan Tradisional Tepuk Bergambar(PT2B) as a context based on the student experience. The purpose of this research is to look at the role of PT2B in helping students'understanding in learning multiplication, which evolved from the informal to formal level in third grade with Pendidikan MatematikaRealistik Indonesia (PMRI) approach. The method used is design research starting from preliminary design, teaching experiments, and retrospective analysis. This research describes how PT2B make a real contribution to the third-grade students of SDN 179 Palembang to understand the concept of multiplication. The results showed PT2Bcontext can stimulate students to understand their knowledge of the multiplication concept. The whole strategy and model that students discover, describe and discuss shows how the students' construction or contribution can use to help their initial understanding of that concept. The stages in the learning trajectory of student have an important role in understanding the concept of the operation number from informal to the formal level.

This study aimed at investigating the progress of students' learning on multiplication fractions with natural numbers through the five activity levels based on Realistic Mathematics Education (RME) approach proposed by Streefland. Design research was chosen to achieve this research goal. In design research, the Hypothetical Learning Trajectory (HLT) plays important role as a design and research instrument. This HLT tested to thirty-seven students of grade five primary school (i.e.SDN 179 Palembang). The result of the classroom practices showed that measurement (length) activity could stimulate students’ to produce fractions as the first level in learning multiplication of fractions with natural numbers. Furthermore, strategies and tools used by the students in partitioning gradually be developed into a more formal mathematics in which number line be used as the model of measuring situation and the model for more formal reasoning. The number line then could bring the students to the last activity level, namely on the way to rules for multiplying fractions with natural numbers. Based on this findings, it is suggested that Streefland's five activity levels can be used as a guideline in learning multiplication of fractions with natural numbers in which the learning process become a more progressive learning.Keywords: multiplication fractions with natural numbers, measurement (length) activity, design research, Hypothetical Learning Trajectory, model of, model for

This study aims to clarify the role of making kemplang can help students understand the concept of number patterns, and generate Learning Trajectory. The methodology used in this research is the design of the research by the research subject class IX students of SMP Negeri 2 South Indralaya, Ogan Ilir, South Sumatra. Researchers designing learning activities that sensing, drafting kemplang class simulated using circular paper prepared by the researcher. Exploration proportional situations using everyday life issues are close to students' lives, such as creating kemplang can make students more interested in learning mathematics and easily understand the math problems are given. Collecting data in this study using video, observation, written tests, documentation and records during the activity. The results of this study indicate that context kemplang and paper-making circles as a model really helps students to understand the concept of a pattern of numbers.Keywords: pattern numbers, manufacture Kemplang, PMRI, design research DOI: http://dx.doi.org/10.22342/jme.7.2.3535.101-108
