The Development of statistics learning design based on realistic mathematics education for grade VIII junior high school

Abstract

The results of the preliminary study indicated that there are problems in learning Statistics at grade VIII SMP/MTs. The students tend to be introduced to the use of formulas without involving the discovery of the concept itself and learning apart from the students' daily experience. This underlies the design of the learning trajectory for Statistics topic and links them to activities based on students' experience (experience-based activities). The purpose of this study was to design a learning trajectory of Statistics topic for grade VIII SMP/MTs based on the Realistic Mathematics Education (RME) approach, that equipped with a teachers' and students' books. This study was a design research that combines the Plomp model with the Gravemeijer & Cobb model. The subjects of this study were the students grade viii MTs Negeri Bangko. This study revealed a Statistics topic-learning design based on RME approach with the learning trajectory that were finding the mean concept, finding the mode concept, finding the median concept, and finding the five series statistical concept. The learning trajectories were implemented through the teachers' book and students' book. The results of conducting experiments showed that the context contained in a students' book that can stimulate the students to develop their knowledge in finding statistical concepts. All strategies was found and discussed by students, show how the construction or contribution of students in finding the statistical concepts from informal to formal level. The results showed that the learning design of Statistics topic basd on RME approach was valid and practical. It was valid in terms of content and language and it was practical in terms of implementation, convenience and time required.
