Development of mathematics learning tools with Realistic Mathematics Education-Jumping Task (RME-JT) and its effect on the mathematic communication skills

Abstract

This research focus on the development of learning based on realistic mathematics education approach with Jumping Task questions. The develop learning are related to the real life of students, so that students can be expected to enjoy and like mathematics. The develop learning consist of lesson plan, worksheet, and learning test. This research used mixed method, both combine development and quantitative research. The model study is Thiagarajan 4D by using independent test analysis. The results showed that realistic in learning mathematics education approach-Jumping Task has a good quality practice, efektive, and fulfill the criteria of validity. On learning process using realistic mathematics education approach, the students are more active, enthusiasm and motivation so that it has a positive impact in improving students' mathematics communication. Significant value is 0.000 (p <0.05)..
