Fraction was very important to be taught as a basis for learning mathematics for the next stage. This research aimed to design fractions learning for fourth grade students. The method used was design research with type of validation studies which consists three stages, namely the preliminary design, the design experiment, and the retrospective analysis. This research was conducted at Madrasah Ibtidaiyah (MI) in Jambi City with research subjects were eleven students in the fourth grade. Based on the research findings, it was concluded that students really followed the command of questions, so as a teacher or question maker, we must design questions clearly. In addition, students tended to operate fractions starting from addition or subtraction, then multiplication, and lastly division.

This research aims to produce learning activities that can help students understand the concept of probability material using the PMRI approach through Prabumulih City market snacks. This research was conducted at SMAN 6 Prabumulih, class 12. The research method used was design research with validation research type (preparation stage and pilot experiment). The instruments used in this research were observation, documentation, interviews and tests. This research produces student learning estimates (HLT) in the form of student learning trajectories in probability material. The researcher tested the sequence of activities and conjectures of students' thinking that had been designed at the preparation stage on 8 students and compared the results obtained. This testing was carried out at the design experiment stage, namely a pilot experiment to produce learning trajectories in the form of appropriate learning activities on probability material, the subject of enumeration rules. The results of data analysis conclude that the resulting learning activities can be seen as an alternative method for teachers to help students learn the concept of opportunity. The context of market snacks that researchers use are relevant to probability material and improve the reasoning ability of students

The purpose of this study is to produce students' learning trajectories in studying addition and subtraction of fractional numbers. The operation of adding and splitting fractional numbers is one of the materials that must be mastered by elementary school students. The learning approach used is the Indonesian Realistic Mathematics Education (PMRI) approach with the context of the Watervang dam. The use of the Watervang dam context is used as a means to apply the concept of addition and subtraction of fractional numbers to real problems. His research uses the validation studies type design research method. The subjects of the study were six grade IV students of SD IT An-Nida Lubuklinggau City. This research produces a learning trajectory (LT) which contains a series of learning activities that help students understand the concepts of addition and subtraction of fractional numbers. Based on the results of the study, it was found that the learning trajectory using the context of the Watervang dam can help students develop an understanding of the concept of addition and subtraction of fractional numbers.

In everyday life, we were asked to be careful in making decisions, especially regarding financial matters. This research aimed to design a financial mathematical task to train students to be wiser in making decisions regarding financial matters. The method used in this research was design research with type of development studies. The approach used in this research was Realistic Mathematics Education (RME) or in Indonesia is better known as Pendidikan Matematika Realistik Indonesia (PMRI). For the context, this research used buying a house with credit or banking context. This research was conducted at Vocational High School 01 Jambi City with the subjects were eleventh-grade students with major of accounting. This research produced a financial mathematical task in the context of buying a house that was valid, practical, and has potential effect for financial mathematics learning. The research results also found that students became wiser in making decisions regarding financial matters. This research can also be a reference for vocational high school teachers to make financial mathematics teaching materials.

A learning process is said to be good if learning is student-centered. Students perform activities in the learning process by using context as a starting point in learning. Design Research with a cycle that contains components of knowledge (K), design (D), experiment (E), reflection (R) is an alternative to create student-centered learning and obtain information and findings in research. This research was conducted in one of the junior high schools in Palembang City with a sample of 23 students. Research procedures were carried out including observation data analysis, interviews and documentation analysis. The conclusion of this research is that the existing knowledge of students is used as a basis for designing learning activities so that when implementing experiments students are able to carry out activities that are related to the initial abilities of students so that the context appears to be a strating point in learning so that the findings that arise can be analyzed and become a reflection to carry out cycles. Then the effectiveness of learning goes according to design and produces a series of understanding of numbers and also the situation of "pulling" and "stretching" in the kite game can be converted into "positive and "negative" symbols

Primary school curricullum lays the foundation of geometry knowledge; students learn geometry by exploring their environment. Many researchers found that students have difficulties in understanding quadrilaterals. Most of them assumed that quadrilateral is square. Therefore, the aim of this research is to develop activities that support students to know the different types and forms of quadrilaterals. A teacher and thirty nine of fifth grade students were invole in this research. We used Cak Ingkling -Indonesian hopscoth- as a context in line with PMRI -Indonesian version of Realistic Mathematics Education- approach. The research finding showed that the use of Cak Ingkling context can help students understand the definitions and types of quadrilaterals. Students have had the understanding that it has many quadrilateral shapes such as square, rectangle, rhombus, parallelogram, trapezoid, and kite.

This study aims to conduct a literature review related to critical thinking skills using the PMRI approach. The method used is a systematic literature review (SLR). The data explored are articles related to Critical Thinking Ability Using the PMRI Approach for the period 2010-2021. From a number of articles that were traced from sinta 1 - 4, 8 articles were found that matched critical thinking skills using the PMRI approach. Based on the results analyzed, it can be concluded that using the PMRI approach can improve critical thinking skills, students are very enthusiastic in learning using the PMRI approach. Creative and innovative teachers using the PMRI approach can make learning mathematics fun, more interesting, less boring and liked by students. In addition, the application of learning with the PMRI approach, as well as the classroom atmosphere can improve critical thinking skills, and also have a direct impact on improving students' critical thinking skills and better student characteristics.
