Abstract

This research aims to improve the division word problem solving ability using Indonesian Realistic Mathematics Education (IRME) in 2^nd grade students at Kanisius Wates elementary school. This research was a collaborative Classroom Action Research that used Kemmis & McTaggart models. Data collection used test, observation and documentation. Data analysis used qualitative descriptive and quantitative descriptive techniques. The criterion for the research success was at least ≥80% students has reached the Minimum Exhaustiveness Criteria (71); as well as the teacher and students activities were in Very Good category. Based on these research, the application of IRME can improve the division word problem solving ability of 2^nd grade student at Kanisius Wates elementary school. The average value of pre-cycle test was 62,42; the ^1st cycle test was 84,46; and the 2^nd cycle test II was 87,00. While the percentage of pre-cycle test was 41.67%, the 1^st cycle test was 75.00%, and the 2^nd cycle test was 87.50%. The percentage of teacher activities was increased from 71,02% (Good) in ^1st cycle to 85,23% (Very Good) in 2^nd cycle. The percentage of students activities was increased from 68,06% (Good) in ^1st cycle to 83,33% (Very Good) in 2^nd cycle.
