The aims this study are to produce Learning Trajectory use Rumah Limas as context. The approach used is Pendidikan Matematika Realistik Indonesia (PMRI). The subjects were 26 students of class seventh of SMPN 1 Keluang. This study was using design research approach, the hypothetical Learning Trajectory was developed from a set of activities using Rumah Limas as context. In theory the development carried through the interactive process comprise of preliminary design, teaching experiment and restrospective analysis to contribute to Local Instruction Theory (LIT) to supporting students learn of angle. Data collected by making video recording about incident in the class, collecting students worksheet, giving pretest and postest, interviewing students. The designed HLT compared with Actual Learning Trajectory (ALT) during teaching experiment to analyze whether the students learned or didnt learn from what we had designed in the instructional sequence. Retrospective analysis of teaching experiment showed that by using Rumah Limas as context can support students learning of angle.

This study aims to generate the valid and practical PISA-like mathematics problems on uncertainty and data using the football game context of Asian Games. It also aims to see the potential effects of the problems towards the high school studentsâ€™ mathematical ability. This study used a design research methodology with the type of development study which was divided into two stages, namely preliminary stage and formative evaluation stage. The preliminary stage covered the analysis of research subjects, curriculum analysis, PISA framework and creating a question instrument. The formative evaluation stage included the one to one consisting of three students together with expert review consisting of two validators, small group consisting of six students, and then the field test. This study produced valid and practical PISA-like mathematics problems on uncertainty and data content which have a potential effect on the senior high school studentsâ€™ mathematical literacy ability. The validity was determined based on the expert review, while the practicality was determined based on one-to-one and small group assessment. The students' mathematical literacy abilities appeared during the research were communication, reasoning and argument, and devising strategies for problem-solving.

This study aimed to create mathematical problems of uncertainty and data contents in PISA using aquatic context that were valid, practical and had the potential effect. This study was design research of development study. The subjects in this study were 10th-grade students of Indo Global Mandiri senior high school in Palembang consisting of 20 students. Data were gathered through interviews, observation, and tests. The results of data analysis showed that there were eight valid and practical items of PISA type of uncertainty and data contents. The contents obtained using bicycles and aquatic contexts in Asian Games. The 11 out of 20 students showed reasoning skills and reasonable arguments, and 9 out of 20 students showed reasoning skills and discussions but incomplete. It was because they were not used to solving PISA type problems in learning.

Developing PISA like mathematics problems using daily life context helps to improve the quality of learning. This study aimed to generate a valid, practical, and having potential effects on mathematics literacy ability PISA like mathematics problems with the context of sailing in the 2018 Asian Games. This research involved three expert reviews and 32 fifteen-years-old tenth-grade students of SMA N 10 Palembang, a public senior high school in Palembang Indonesia, as the research subjects. This study used the design research method of development studies type. The data were collected through documentation, walkthrough, tests, and interviews. The problem developed in this study is related to the length of wood required to span the sail. The results show that the problems are valid. The validity was viewed from its compatibility with the PISA framework, in which it had related the problems with daily life context of sailing in the 2018 Asian Games and space and shape content. The problems are also practical, viewed from students' understanding of the problem. And, the problems have potential effects when tested in learning issue of mathematical literacy ability. The dominant ability is reasoning and representation ability, while the communication ability is still low because the students do not give detailed answers.

This research was motivated by several studies which show that students have difficulties in understanding the material ratio, wherein one contributing factor is the lack of ability in proportional reasoning. The purpose of this study is to produce a trajectory of learning to help students develop abilities in comparison reasoning. Solution strategies in this study were the ratio tables and graphs using PMRI approach (Indonesian Realistic Mathematics Education) with OKU Timur context. This research was conducted in MTs Subulussalam 2 Sriwangi Ulu OKU Timur. The method used was design research with three stages, those are the preliminary experiment, design experiment, and retrospective analysis. At the preliminary experiment, researchers designed the Hypothetical Learning Trajectory (HLT). At the design experiment, HLT tested on students to develop informal knowledge into a formal knowledge of mathematics through activities. The trial results were analyzed in a retrospective analysis phase so that the trajectory of learning or Learning Trajectory (LT) resulted.DOI:Ã‚Â http://dx.doi.org/10.22342/jme.8.2.3969.211-222

This study aims to produce valid and practical PISA-like mathematics problems of uncertainty and data content by using soft tennis and volleyball contexts in Asian Games. It also aims to find out the potential effect of the problems on students' mathematical literacy. The method used in this study was design research with the type of development studies. The validity was viewed from expert assessment regarding the content, constructs, language, and studentsâ€™ comments to the clarity of the problems in the one-to-one phase. Then, the practicality was viewed in the small group phase, and it was found that the students could understand the problem well. Based on the answers from 33 tenth-grade students of senior high school, it was found that the problems had potential effects that arouse the ability to use symbolic, formal, and technical language, as well as the ability of operation, communication, and representation. With the problem of the soft tennis context, five students could apply the ability to use symbolic, formal, and technical language, and operations, 12 students could apply representation ability, and 16 students could apply the communication ability. Meanwhile, with the problem of the volleyball context, 18 students could apply the communication ability, and nine students could apply the representation ability.

This study aimed to develop a set of PISA-like mathematics problems on uncertainty and data content using football as a context which was valid, practical and had potential effects on studentsâ€™ mathematical literacy ability. The method used in this study is design research with development studies type which had two stage: the preliminary and formative evaluation. Tenth-grade students of senior high schools in Palembang were involved in this research. This study produced a set of PISA-like mathematics problems at 3, 4, and 5 level. In this case, studentâ€™s strategies used some ability in solving one of the problems, namely mathematizing, representation, and communication ability. There were 16 out of 35 students using mathematizing and communication ability, 10 out of 35 students using representation and communication ability, and 9 out of 35 students only using communication ability. Also, the results of the interview with some students showed that they liked to do such PISA-like mathematics problems because they could improve their literacy ability in solving the PISA-like problem.
