Development of teaching materials based on realistic mathematic education and its implementation in improving students’ creative thinking skills on comparative material

Abstract

4C’s skills (creative, critics, collaborative, communicative) are the skills that are required in the 21st-century era. Accordingly, creative thinking ability is one of the demands required. It can be develop anywhere; one of them is in the implementation of learning conducted at school. The learning implemented by the teachers at school is expected to maximize the development of students’ creative thinking skills. The learning model of realistic mathematics education (RME) is one of the learning models used to optimize learning. This research aimed to study the students’ creative thinking ability and the RME learning model’s implementation in improving students’ creative thinking ability in solving the problem in comparison material. In this research we used a new study, this study was combining among qualitative method and quantitative methode, we call it with mixed method. This research involved 70 respondents in the same school who were divided into the experimental class and control class. The first class there are 35 students from control class and the second class there are 35 students from experiment class. The result showed that there was a significant difference, as shown up in the value of independent t-test toward the post-test. The result of the research showed that the post-test stage in the control class revealed that 16% students were in the category of uncreative, 33% students were quite creative, 29% students were creative, and 22% students were very creative and in the experimental class, it was found that 9% students were uncreative, 18% students were quite creative, 31% students were creative, and 42% students were very creative according to the level of creative thinking ability. The data analysis presented that the value of independent sample t-test from the post-test was sig. 0.00 (p 0.05), tBerefore it was significant. Thus, there was an effect of the implementation of realistic mathematics education (RME) in improving students’ creative thinking ability in solving problems in comparison material.
