The Use of Grid 10 x 10 in Learning The Percent

Abstract

The percent symbol is often used in a variety of media in daily life. Students have difficulty in solving the problems dealing with percentage, even though they know little about percent. Therefore, this research was aimed to obtain learning trajectory percentage using grid 10 x 10 by Pendidikan Matematika Realistik Indonesia (PMRI) approach and find out the role of grid 10 x 10 in helping students to comprehend the percentage problem. The method of this study was design research type validation studies which were aimed to prove the learning theories. Research design consisted of three phases, those are preliminary, experiment design, and retrospective analysis. This research was conducted in SD negeri 3 OKU by involving fifth grade students. The data of this research was collected by using video, documentation, pre-test, the students’ activity sheets, post-test, and interview. The data were analyzed qualitatively. The result of this research showed that the learning trajectory which was designed consists of three activities which every activity is divided into two and grid 10 x 10 has a role in percentage learning.
