PENERAPAN PENDEKATAN REALISTIK MATHEMATICS EDUCATION UNTUK MENINGKATKAN HASIL BELAJAR SISWA MATERI HIMPUNAN MENGGUNAKAN VIDEO PERMAINAN 17AN

Abstract This study aims to obtain a description of the application of the Realistic Mathematics Education (RME) approach that can improve student learning outcomes on set material in class VII SMP Madinatul Hadid. The type of research conducted is classroom action research (CAR) which refers to the research design of Kemmis and Mc. Taggart is planning, action, observation, and reflection. This research was carried out in 2 cycles. The results showed that the application of the RME approach could improve student learning outcomes on set problems by using 17an video games. In the step of understanding contextual problems, the researcher gave a video about the 17s game and students were given questions to group the data. In the problem solving step, students are asked to solve the problem. The researcher guides students who have difficulty and provokes students' understanding of the grouping, and in cycle II the researcher encourages students to make groupings into venn diagrams. In the step of comparing and commenting on the work, students are asked to show the results of their work or present them in front and see the differences between each person. Researchers play a role in directing students to the correct answer if the student's answer is not quite right. In the conclusion step, the researcher directs students to conclude today's lesson or the teacher gives a brief conclusion.
