Abstract

One of the demands of 21st century learning is critical thinking. However, nowadays, students' critical thinking skills are still relatively low, particularly in geometry. This research aims to explore students' critical thinking skills through the design of a series of lessons. Realistic Mathematics Education (RME) underlies the design and the context applied. This study was conducted in one of the elementary schools in Jakarta, involving 30 grade IV elementary school students as the research subjects. The method used in this research is descriptive qualitative with an educational ethnographic approach. Data collection techniques involved observation, interviews, and documentation. The results of this study indicate that the implementation of a traditional game-based learning design called Damdas 3 Batu can support students’ critical thinking skills. Through this game, students are able to comprehend the given problems, construct mathematical models adapted to the provided context, solve the problems, and ultimately derive conclusions from the obtained results. Therefore, Damdas 3 Batu can serve as a valuable instructional reference for teaching geometry concepts in elementary schools.

Abstract

At the end of the sixties of last century, the development of Realistic Mathematics Education (RME) started in the Netherlands. At the beginning of this century, the Indonesian adaptation of RME, Pendidikan Matematika Realistik Indonesia (PMRI), started. The implementation of RME / PMRI has proven to be challenging. In this research, a qualitative case study was used to investigate teachers’ perceptions and experiences in implementing RME/PMRI in their classes. Semi-structured interviews were conducted with several Dutch and Indonesian teachers who have joined the RME/PMRI training. We found similarities and differences between the two groups of teachers. Both groups of teachers understand the use of context as a starting point for students to construct mathematical understanding. The Dutch teachers considered the construction of interesting mathematical problems and the use of the guided-reinvention principle as the difficulties but motivated them to do more practice. Indonesian teachers mentioned that for them, the integration of mathematics with other subject areas for integrated thematic learning in the 2013 curriculum was their constraint but it was also a challenge for them to be more creative. These perspectives can become a reference for the development of a localized implementation of learning trajectory in classroom practices. DOI: https://doi.org/10.22342/jpm.17.1.20097.103-120
