The purpose of this research is that students are able to understand the basic concepts of Least Common Multiple (LCM) easy by using traditional games in Palembang, namely Bom Angka. The method used is design research with preliminary design, teaching experiment, and retrospective analysis stage, with the subjects were primary school students in the fourth grade. The results of this study indicate that the use of the traditional game in LCM motivated students to be more interested in learning mathematics, because students can learn and play at the same time. In addition, the pronunciation of numbers in sequence once uttered a bomb in every multiple of the numbers that have been agreed enables students to think quickly while helping students memorizing multiplication automatically, who were eventually able to instill the concept of LCM well.Â

An increasing number of Papuans qualified teachers realized by sending young people from Papua to continue their education in the College of Education. But the basic capabilities, especially mathematics, which owned high school students graduated from Papua that continuing education is very low. This, presumably because the students have math anxiety, thus preventing them from material master mathematics. By using a qualitative research approach, particularly the case study method, this research describes what factors are the cause of math anxiety prospective teacher students from Papua, based on the results of questionnaires and interviews that have been analyzed.Â Â Â

This research is motivated by the low mathematical communicating skills of junior high school students. The aim of this study is to know the differences in average score of mathematical communicating skills between the students once learnt using realistic mathematics education approach and students learnt using conventional approach. This research used a quasi-experimental method with non-equivalent control group design. The population used were all 7th grade students in SMP Negeri 2 Pagedangan, with two classes used as samples. This research datas are obtained from studentsâ scores in pretest and posttest. Based on the analysis of the research results, it is concluded that there are differences in the average score of matematical communicating skills between the students once learnt using realistic mathematics eduacation approach and conventional approach. The average score of mathematical communicating skills of the students learnt using realistic mathematics education approach is higher than the students learnt using conventional approach.

This research is motivated by the low student learning outcomes in the material triangle and parallelogram caused by a lack of understanding of students about the forms of flat wake triangle and parallelogram so when the teacher gives about the shape Flat figure that is different from that taught teachers, students find it difficult to do. Therefore the use of learning with math GASING (easy, fun, and enjoyable). The purpose of research is to know the size of the average N-gain in the ability of students mathematical understanding once taught using learning math GASING. This research was conducted in SDN RUMPAKSINANG with grade IV samples of 31 people in November 2015. The method used in this research is the type pre-experimental design with the design of one group pretest-posttest. The results showed from this research that there is an increased ability to learn the students understanding after learning of Mathematics GASING. The increase was seen from the average N-gain of 0.3813 which is included in the medium category.

This study aims to determine the factors of studentâs learning difficulties and the implementation of problem-based learning to studentâs mathematical understanding. Subjects in this study is the student of class VIII A SMP Muhammadiyah 6 Yogyakarta. The techniques of data collection used observation and interview to determine the factors of learning difficulties and evaluation methods to determine studentâs mathematical understanding ability. Type of research used is single subject research with basic design of A-B. The results of this study indicate that the studentâs learning difficulties experienced by students is caused by social factors that is from a classmate. Furthermore, problem-based learning can improve studentâs mathematical understanding. It can be seen from the average score obtained by the student before the treatment given that is 28.5 and increased to 94 after treatment.

One of the geometry subjects that has a high level of difficulty and abstractness is the 3D-shape subject (solid geometry), especially the surface area of a polyhedron. Students have difficulty in imagining objects and constructing previously owned knowledge. One approach that uses prior knowledge as a starting point for learning is the Indonesian Realistic Mathematics Education (IRME) approach. This research is a qualitative descriptive study that aims to describe the learning of surface area of polyhedron using the IRME approach to eighth-grade students in SMP Negeri 1 Banguntapan. The subjects of this study were all eighth-grade students of SMP Negeri 1 Banguntapan Yogyakarta. Data collection techniques used were video recording, observation, and interviews. Video recording is conducted to observe student activities during the learning process and compare them with observation and interview sheets. Meanwhile, the test instrument is used as supporting data to see student learning outcomes after learning the surface area of the polyhedron as the whole topic. The results showed that during the learning process, which lasted for two meetings, students could follow well all stages of learning by fulfilled the five characteristics of IRME and getting good results.

Yogyakarta has a nickname as the City of Culture. Yogyakarta has several cultures that are closely related to the context of learning mathematics. However, not many educators in Yogyakarta see this culture as a context that can be a starting point in learning mathematics. Thus, this study aims to explore the culture of Yogyakarta's people that can be used as a context in learning mathematics. This study uses ethnographic studies sourced from literature studies, field observations, and interviews with informants who understand the ancient Javanese language well to clarify and / or provide more understanding of the results of the literature review collected. The results showed some mathematical languages used by the Yogyakarta people in Javanese that could be used as starting points in learning mathematics. This mathematical language includes the mention of numbers, area, angle, volume, indefinite units, and determination of time units.

Learning mathematics has a significant contribution to the studentsâ€™ 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 studentsâ€™ learning outcomes with an average score of 81.92% and 92.59% of the total of students scored above passing grade.
