Intersection and union concepts are crucial part of operation in sets, especially in solving word problems and creating the venn diagram. In fact, not a few students do fallacies in representing sets word problems into a sets operation, so they do mistakes in solving the problems. This study aims to investigate students’ thinking in learning intersection and union concept, specifically by using colored cards. The learning is designed under Realistic Mathematics Education (RME) approach and the principle used is emergent modeling. The method used in this study is design research. The subjects of this study is 25 students of the 7th grade junior high school, in which five of them were the focused group. The main findings in this study are description of students’ thinking while learning union and intersection using colored cards in the class, and any kinds of students’ ‘diagram venn’models. Keywords: design research, intersection, realistic mathematics education, union, venn diagram

Trajectory Learning

The topic of the set is a basic concept in mathematics and its relationship is close to our daily life. However, some studies in Indonesia have found that the students have difficulties in solving the set problem. This can be due to the pattern of mathematics teaching in schools. This study aims to provide a design of learning in the set topic with Realistic Mathematics Education (RME) approach. The research questions are: (1) How is the design of mathematics learning in the topic of the set using the RME approach? (2) How do students learn the topic of the set by using the RME approach? This research method is design research with one cycle in SMP Dasana Indah Tangerang. The subjects were 24 students with one focus group, 5 students who had no errors in the initial test. Data of research obtained from sound recording, video, photos, and Student Activity Sheet, then be analyzed by comparing the Hypothesis of Trajectory Learning and Trajectory of Actual Learning. This study produces the Theory of Local Instruction, with four lessons, namely: (1) Determining the set and not the set; (2) Finding the concept of set of universe, subsets, empty set, and describing the models; (3) Finding the concept of intersection, union, and illustrating the models; (4) Find the concept of complement, difference, and describe the models, and use the models to solve the story problem. In the learning process, through grouping games and describe the model, student learning the notion of set enthusiastically and actively. Keywords: design research, set, realistic mathematics education approach

The purpose of this research is to understanding the role of line and angle learning design in students’ comprehension of mathematical concept and also to understanding the students’ learning result through LAS (Lembar Aktivitas Mahasiswa) or student activity paper that is based on the Indonesian Realistic Mathematics Education approach. The research method used in this research is design research. The result of this research shows that the activity of using props or drawing a clock circle could motivate the students in checking out the shaped angle, So the students will have the idea to calculate how big is the angle that is shaped by the clockwise and also to determine its types. So, the design that is used could help the students to understanding the concept of angle through the context of clock circle.

Geometry is an essential subject for students. However, geometry, especially the cone, remains a challenging material for students. Besides, we need the proper media and context for learning mathematics on cone material. This research aims to develop a learning trajectory that utilizes the Megono Gunungan tradition as a context in the learning process using the Indonesian Realistic Mathematics Education (PMRI) approach. The research method used is Design Research, which consists of three phases of the study: preliminary design, experimental design, and retrospective study. This study's outcome is designing a learning trajectory on cone material using the Megono Gunungan tradition. This learning trajectory comprises four activities, including observing the interactive video of the Megono Gunungan tradition to discover cone elements, finding the concept surface area of a cone using origami paper, and grasping the cone concept volume with magic seeds, and solving contextual problems related to the cone. Studies have shown that using the Megono Gunungan context could help students improve their understanding of the cone concept. Furthermore, this study hoped could be an inspiration for exploring another local wisdom that can be a context in learning mathematics.

This research is motivated by students’ learning obstacles in direct & indirect proportions concept through literature studies and preliminary studies conducted by a researcher. Furthermore, the environmental care attitude of students is low. The purpose of the research is to create the alternative didactical design; a didactical design Realistic Mathematics Education based on Green Mathematics consisting of four lesson designs arranged due to learning obstacle in direct & indirect proportions concept, as well as relevant learning theory.  Four lessons were implemented for 40 seventh grade students in Lembang who have not learned yet about the concept. The research method used in this study is qualitative research as Didactical Design Research. There are three stages in this study; the first stage is prospective analysis or didactic situation analysis producing hypothetical didactic design, the second stage is metapedadidactic analysis as implementation of hypothetical didactic design, and the third stage is retrospective analysis that produces empirical didactic design. The result shows that hypothetical didactic design can minimize the students’ learning obstacles in direct & indirect proportions concept; almost all student showed environmental care attitude is well; and almost all student showed positive attitude towards mathematics learning using hypothetical didactic design. Based on the results of the research, developed didactical design that can be applies as one of the alternative for teaching materials in direct & indirect proportions learning concept at schools that have the same characteristics.
