The Development of Students' Learning Material on Arithmatic Sequence Using PMRI Approach

摘要

The aim of the learning process in this study was to help students find concepts on arithmetic sequence materials using the approach of Pendidikan Matematika Realistik Indonesia (PMRI) as well as produce a path of arithmetic sequence learning using PMRI approach. This research method was design research which was an appropriate way to answer research questions and achieve research objectives. The research procedure used was preliminary design, teaching experiment and retrospective analysis. This research was conducted on the students of class X in one private high school. The main data analysis techniques were restrospective analysis in collaboration with counselors to improve the validity of the research results. The results showed that the use of PMRI approach provides an important role in learning arithmetic sequence and increasing student's motivation to learn. Context used and interesting learning guided students to explore and use strategies to solve problems related to arithmetic sequences in everyday life. Then learning trajectory of a HLT (Hypothetical Learning Trajectory) was generated. The learning path of students in arithmetic learning progresses from the informal to the formal stage so as to enhance students' understanding of arithmetic learning.
