Abstract

The objective of this research is to determine the Realistic Mathematical Approach in mathematics learning with subject matter of comparing fractions in class III of Public Primary School 040457 of Berastagi.The type of the present study is a classroom action research. Data analysis technique used in this research is quantitative and qualitative descriptive analysis method, with the aim to know whether application of demonstration method can improve the learning outcomes of students.Based on the results of research and data analysis that has been conducted, it is evident that through the application of Realistic Mathematical Approach the learning outcomes of mathematics of students can be improved.
