Abstract

Abstract This research aims to describe students’ translation and transformation ability on mathematical representation in solving contextual word problems of sets in class VIII SMP Negeri 18 Pontianak. The method that was use in this research is descriptive method with case study form. The subject of this research are 35 students. The data collection instrument that used is written test in essay and interview as the follow-up activity. The result of data analysis showed that the students’ translation ability on mathematical representation from the verbal representation  to the symbol representation (sets symbol) is classified as very low with percentage 100%; students’ translation ability on mathematical representation from the symbol representation (sets symbol) to the visual representation (Venn diagram) is classified as very low with percentage 60%; students’ translation ability on mathematical representation from the verbal representation  to the symbolic representation is classified as very low with percentage 100%; students’ transformation ability on mathematical representation in symbolic representation is classified as very low with percentage 51.43%; and students’ transformation ability on mathematical representation in verbal only a small part with percentage 40% which reached very high. Kata kunci : kemampuan translasi, kemampuan transformasi, soal cerita   kontekstual, himpunan

Abstract

The purpose of this research is to improve the concept understanding of twodimentionalfigure by using Media Realiaof the student in Grade IIIB of state Primary Schoolof Bratan 1 in Academic Year 2016/2017.This research used the classroom action researchwith two cycles. Each cycle consisted of four phases, namely:planning, implementation,observation, and reflection. The subjects of the research were the students as many 34 studentsin Grade IIIB of the school. Data analysis techniques that use data collection, data reduction,data presentation, and withdrawal of conclusions. Data validity using technique triangulationand source triangulation.The results showed that by using Media Realia can improve theunderstanding of two-dimentional figure on IIIB students SD Negeri Bratan 1 academic year2016/2017. Before using Media Realia is seen, the students who reach the KKM consist ofonly 11 students or 32,35% in pre-action data. In the first cycle by using Media Realia studentsmastery increased to 67,65%. In the second cycle by using Media Realia students mastery roseto 85,3%. From the results of my research can be concluded that by using Media Realiacanimprove understanding of two-dimentional figure state in the students of grade IIIB SD NegeriBratan 1 academic year 2016/2017.
