The objective of this study was to investigate the role of the context to enable the students to understand the concept of volume of a sphere in class VIII. The context of this research was using a watermelon as teaching aids by using PMRI approach. The method used in this study was design research; the stages were preleminary design, teaching experiment, and retrospective analysis. The results of this study indicated that the role of watermelon as teaching aids supported the students to develop their knowledge about the concept of volume of a sphere, and enhance their understanding about the material so that the learnin becomes more meaningful. In giving the volume of a sphere its better not to be taught the students by giving formula directly, however they were given the opportunity to understand the volume of a sphere with their own concept in real situation. The existence of such a situation, the student will be easier to learn the material volume of a sphere at a higher level.

This study was conducted to produce the learning trajectories in volume of cubes and cuboids  involving spatial visualization ability eight grade . In this study involving eighth grade students of SMP YPI Tunas Bangsa Palembang academic year 2014 - 2015. The method used in this study is the type of research design validation studies that consists of three stages: preliminary, design experiments, and retrospective analysis. A series of learning instruments designed and developed based on allegations of learning and using PMRI approach. In this paper will discuss the pilot experiment phase. Activities carried out starting from the activities see the packaging to improve spatial visualization ability of students, conduct experiments to enter rubik and resolve problems related to daily life - today. The results showed that the activities of the learning process through a series of activities based on the experience has helped improve students understanding of the concept the volume of cubes and cuboids.

The research is purposed to generate a learning trajectory that supports students to understand the concepts of exponential through the context vegetative propagation in animals. The Design Research was chosen as the exact method to achive the objective. Hypotetical learning trajectory in the design research played an important role as the design and research instrument. Hypotetical learning trajectory was designed as the preliminary design and was examined to 50 students from the ninth graders of YPI Tunas Bangsa Junior high school. (e.g 6 students from pilot experiment and 44 students from teaching experiment). The result of the learning experiment showed that drawing activity of the process of animal vegetative propagation could motivate the students to see the form of the animal multiplication. While seeing the animal multiplication through modeling (scheme, chart, and diagram), the students had an idea to calculate new animals had been formed, and used multiple numeral to determine the sum of the new animals. From the multiple numeral, an idea to state it in terms of repetitive numeral would bring the students into a definition of exponential. Based on the result above, its suggested that context containing multiplication form be used, let the students see multiplication, and the students do it mathematically into the basic concept when they are learning exponential.

This research aims to determine the student’s higher order thinking skill (HOTS) after learning using the PMRI through LSLC is done approach to the material of number patterns in class VIII. This type of research is descriptive. The subjects of this study were students of class VIII.5 Junior High School number 18 Palembang amounting to 31 students. Data collectin techniques used were observations, giving test questions amounted to one questons in the form of descriptions, and interviews. After conducting the research, there have been many indicators of higher order thinking skills raised by students even though there are still some students who don’t bring up indicators. In addition, by using the PMRI approach and the LSLC system, students become mutually learning and active in learning. The conclusion of this research is the ability of HOTS students in class VIII.5 is enough, which can be seen from the scores obtained by students in the test questions that are in the range of grades 41-60. In addition, the emergence of the analysis (C4) indicator most often appears as much as 63.33%, evaluation (C5) as much as 30% and the creation (C6) indicator is the least indicator that appears as much as 20%.

This study aims to discover how the mathematical problem-solving ability of students in class VIII using Pendidikan Matematika Realistic Indonesia (PMRI) through Lesson Study for Learning Community (LSLC) on straight-line gradient material. The subjects of this Study were Students of class VIII.B Srijaya State Junior High, totaling 32 students. The learning process takes place adapted to the principles and characteristics of PMRI through the LSLC system. Data collection the techniques used in this study were observation, written tests consisting of two problem descriptions, and interviews conducted to obtain supporting data. The observation was to see student activities during the learning process. The tests are conducted to find out how students mathematical problem-solving abilities. The interview is used to confirm the student's answers. Obtained students' mathematical problem-solving abilities on the Straight-Line Gradient subject and had reached the indicators of understanding the problem, planning solutions, and implementing plans with the most indicators often appear is the indicator of planning a solution. In contrast, the indicator that rarely appears is the indicator of the truth of the completion of the problem. The conclusion of this research is mathematical problem solving of 8th-grade students using PMRI through LSLC on gradient material category was enough.
