Various studies show that Indonesian students' mathematics literacy is very low. The low level of mathematics literacy is influenced by many factors including the fact that mathematics learning does not relate to culture. The term used to relate mathematics to culture is called Ethnomatematics. The purpose of this study is to determine the learning trajectory of geometrical transformation based on Ethnomatematics of Traditional Balinese Houses that can improve mathematical literacy. This type of research used is a design research type validation study consisting of 3 phases, namely: (1) preparation of experiments, (2) experiments, and (3) retrospective analysis. The study was conducted of Laboratory Undiksha Junior High School. The data of this study were collected by observation, interviews, and tests. Furthermore, the data were analyzed descriptively. The results showed that the learning trajectory of geometry transformation begins with the giving of problems, phenomena, patterns, pictures, which are related to Ethnomatematics of Traditional Balinese Houses. Furthermore, students conduct investigations individually or in pairs related to mathematical ideas that exist in Ethnomatematics. Through discussion, students construct mathematical knowledge. Another result is that students become more enthusiastic in learning, and students' abilities in solving mathematics literacy problems become better.

Abstract The percent symbol is often used in a variety of media in daily life. Students have difficulty in solving the problems dealing with percentage, even though they know little about percent. Therefore, this research was aimed to obtain learning trajectory percentage using grid 10 x 10 by Pendidikan Matematika Realistik Indonesia (PMRI) approach and find out the role of grid 10 x 10 in helping students to comprehend the percentage problem. The method of this study was design research type validation studies which were aimed to prove the learning theories. Research design consisted of three phases, those are preliminary, experiment design, and retrospective analysis. This research was conducted in SD negeri 3 OKU by involving fifth grade students. The data of this research was collected by using video, documentation, pre-test, the students’ activity sheets, posttest, and interview. The data were analyzed qualitatively. The result of this research showed that the learning trajectory which was designed consists of three activities which every activity is divided into two and grid 10 x 10 has a role in percentage learning.

Mathematical communication skills is an important role in mathematics learning. However, the importance of mathematical communication skills has not been fully realized in learning, especially circle material. Design a learning material based on mathematical communication is one way to develop this ability.  The preliminary study produced the findings of an epistemological learning obstacle so that students' mathematical communication skills were still in the low category. This study aimed to analyze learning obstacle and designing learning materials based on the material mathematical communication circle. This study is design research that contained two stages of Didactical Design Research (DDR), didactic situation and metapedadidactional stage. Research result obtained are students difficulties in relating the material defining elements of the circle with their own language, identifying circle elements that were known and explaining through pictures, calculating the circumference and distance of circular objects based on problems, calculating the surface area of circular objects based on the problems, and rearrange the formula which states the relationship of circle elements. To solve that learning obstacle, we recommend some learning trajectory in a circle that useful for teachers. This design of learning material is valid and practical to implement in the classroom.

One factor that has a big influence on mathematics learning outcomes and how students provide solutions to mathematical problems, among others, is the learning factor as well as initial mathematical knowledge (IMK). So, the objectives of the research are to find out: (1) the influence of the Realistic Mathematics Education (RME) Approach aided by Microsoft Mathematics software on students' mathematical communication ability (MCA), (2) an interaction between IMK and RME approach to mathematical communication ability, (3) the students' completion process in solving mathematical communication problems. The third objective is very important because it can reveal whether horizontal and vertical mathematization as the ideas of RME benefit the students. The results of the research show that: (1) there is a significant effect of the RME Approach aided by  Mathematics software on students' mathematical communication ability, (2) there is no significant interaction between the initial mathematical knowledge and the learning approach to students' mathematical communication ability, (3) the students' completion process in solving  mathematical communication problems attain the "good" category.

One of the problems in modern mathematics learning is mathematical concepts presented by teachers to students such as machines. So, the concept is used by students as finished products without knowing the origin and how to reconstruct them. The effort that can be made by the teacher in overcoming this is by designing learning wherever possible starting with presenting realistic problems to arrive at an abstract idea. In this article we will discuss the design of sine rule learning in the context of scout tents, which is a type of design research. Design research has three cycles, namely preliminary design, classroom experiment, and retrospective analysis. In this article only the preliminary study phase will be discussed, which includes literature study activities, curriculum analysis, and the design early prototype. An HLT (Hypotetical Learning Trajectory) has been produced which deals with sine rules that use the context of scout tents.
