High Order Thinking Skills: Can It Increase by using Realistic Mathematics Education?

Abstract

This research aimed to know (1) mathematics learning by realistic mathematics education which increase students’s high order thinking skills, (2) the increasing student’s high order thinking skills by using realistic mathematics education. This research used classroom action research as the method which consists of four stages: planning, action, observing, and reflection. This classroom action research was conducted in one of the senior high school in Tanjung Morawa, Indonesia. The result of this research indicate that realistic mathematics education can increase students’ high order thinking skills. The increasing of students’ high order thinking skill can be seen by the mean of score in cycle I which is 61,94 and 86,39 in cycle II. The increasing is also seen in classical completeness in cycle I which is 33,33% and 86,66% in cycle II. The N-Gain in cycle I is 0,42 in medium category and 0,70 for cycle II in high category.
