Improving Students’ Critical and Creative Thinking through Realistic Mathematics Education using Geometer’s Sketchpad

Abstract

Abstract. Learning that can foster good character in students as well as form an understanding by using technology as mandated Curriculum 2013 has not been fully implemented by the teacher. One that can be done to realize that expectation is to use the Geometer's Sketchpad Realistic Mathematics Education (RME) to train critical and creative thinking. This study aims to improve the character of students through Realistic Mathematics Education of Geometer's Sketchpad on comparative material in junior high and analyze the learning result after applying Realistic Mathematics Education with Geometer's Sketchpad. The subject of this research is the students of class VIII, amounting to 25 people in one of SMP Aceh Tamiang. Instruments used in the study are character observation sheets, and test learning results. Data processing technique used is descriptive analysis. The result of data analysis shows that the application of Realistic Mathematics Education with Geometer's Sketchpad on comparative material in junior high school can improve student's character and student's learning outcomes meet the criteria of mastery.
