PENERAPAN PENDEKATAN PMR UNTUK MENINGKATKAN PEMAHAMAN KONSEP MATEMATIS SISWA KELAS I SD

Abstract

This research is motivated by the lack of understanding students’ mathematical concepts in the first grade elementary school clasroom. Researcher uses realistic mathematics education (RME) approach with principles didactical phenomenology, guided reinvention and self develope models to solved that issue. This research aims to decribed: 1) the lesson plan 2) action process by appliying RME approach to improve understanding students’ mathematical concepts, 3) the result of improving understanding students’ mathematical concepts by applying RME approach. Participans on this research amount 24 students of C elementary school, Bandung. Researcher used classrom action research Kemmis & Taggarts’ model; planning, action, observation and recflection in two cycle. Data collection used in this research are obervation and test. Instrument data are observation sheets and student’s work sheet. Data processing is through: 1) qualitative analysis that’s reduction, classification, display and reflection data, also conlusion, 2) quantitative that’s scoring, calculate aerage, percentage, interretation and conlusion. Research result showed that classical completeness in cycle one is 67% and 83,3% on cycle two. Based on these results it can be concluded that the application of realistic mathematics approach can improve the understanding of mathematical concepts as elementary school students
