Learning Fraction With Indonesia Realistic Mathematics Education (PMRI)

This paper is aimed to describe the activity of designing learning activities, implementation, and the effect of the activity to student learning outcomes. The plan activities are aimed to support 4th grade of SDN 20 Indarung Padang students on understanding in fractional addition by using Realistic Mathematics Education (RME) Approach. The research itself utilize classroom action research design with qualitative and quantitative research approaches. There two cycles that would be explained in the paper. Each cycle consists of planning, execution, observation, and reflection. The results showed an increase in every aspect that are observed. The effectivity of lesson plan increases from 89.29% in cycle I to 96.43% in cycles II. Teacher's activity go up from 75% in cycle I to 95% on the cycle II. It is also affected students` activities from 77.5% to 95%. The average of Students cognitive, affective and psychomotor learning outcomes improves respectively from 74.22 to 83.75, 66.54 to 80.47, and 66.54 to 80.47. It can be concluded that the RME approach improve students' understanding of addition of fractions, students' affective and psychomotor learning outcomes of 4th grade of SDN 20 Indarung Padang.
