Abstract

This research was aimed at producing a learning trajectory, which could help the students to understand the concept of permutations study via role playing activity in the election of chairman and vice-chairman of Intra School Students Organization. The design of this research was Indonesia’s Realistic Mathematics Education approach. The sample of this reasearch were 36 students of the tenth grade of Senior High School No 15 Palembang. The data were obtained from observations, recorded vedeos, photos, students’ sheet activities, and field documentations. The result of this research showed that the learning trajectory could help the students to understand the concept of permutations study. By using role playing activity, the students have determined the administrative committee of chairman and vice-chairman election of Intra School Students Organization from 2, 3, 4, and 5 candidates, which will enable them to choose the number of formed groups arrangement, and to help them in understanding the concept of permutaions from that election.

Abstract

This study aimed to produce a learning path that can help students understand the concept of percent using the context of an egg rack. This study used a design research method through the Indonesian Realistic Mathematics Education approach which was carried out at Elementary School No. 2 Gumawang, Indonesia. Data were obtained through observation, photos, video recordings, student activity sheets, and field documentation. The result of the research was a learning trajectory consisting of three activities; first, students explore their knowledge of egg racks which are very close to students' self-life, secondly, students change the problem into a bar form based on students' knowledge of egg racks, then students change the problem into fractions and students change the fraction with the denominator one hundred, third, students solve the percent problem in a more complicated form. The activities that have been produced and tested on percent learning using the context of an egg rack, can help students to better understand the concept of percent.
