The Difference on Students‘ Mathematical Creative Thinking Ability Between Realistic Approach With Conventional in The State Madrasah Tsanawiyah 2 of Medan

The ability of mathematical creative thinking is one of the targets in mathematics learning. Therefore, a relevant learning approach is needed to encourage students to discover concepts of mathematics by constructing their own knowledge through problems on their daily live, improving creative thinking in understanding the information to resolve a problems
and one approach that can be applied is a realistic approach. This study aimed to analyze: (1) The difference on students’ mathematical creative thinking ability between whom given realistic approach with conventional, and (2) The interaction between learning approach and prior knowledge of mathematics on students' mathematical creative thinking ability. This experiment used pretest-posttest control group design. The population was all students of the eight grade in the State Madrasah Tsanawiyah 2 of Medan and sample were randomly selected of two classes. The statistic testing applied in data
analysis was the mean difference test and the interaction test between the learning approach and the prior knowledge of mathematics. The result showed that there is a difference on students' mathematical creative thinking ability between whom given realistic approach with conventional and the mean difference is 4,657. Further, there is no interaction between learning approach with prior knowledge of mathematics on students' mathematical creative thinking abilities. So, the realistic approach can be used as an alternative in learning mathematics to students’ mathematical creative thinking ability.
