Use of RME approach in learning of KPK and FPB toincreasecritical thinking skill
AbstractThis paper is a Classroom Action Research conducted in 5th grade of Primary School.This research was conducted in three cycles to see the effectiveness of Realistic Mathematics Education approach in learning about the Biggest Fellowship Factor and Multiple Fellowship in Improving Student Critical Thinking Abilities. Critical Thinking is one of four 21th century skill through Mathematics. In the process of lesson, students will be train the oherskill; comunication and colaboration. The background of thisresearch is Students who have aconcept of mathematical form but not able to solve daily lives problems. The implementation of the study in first cycle of learning to use the problems in their daily lives with completion student by using a real object. In second cycle of learning with daily lives problems, thestudents do a simulation of FPB. In third cycle of learning with daily lives problems andstudents solve problems using the math concept, the students has been managed to construct aconcept. Author argues that this concept will be able to be used to solve the problem and match the way with the RME approach. The result of research proven learning Realistic math canimprove students Critical Thinking abilities.
