Daftar Isi:
- Proportional reasoning is one of fundamental topics in middle grade mathematics. This study reports a part of full study about how to support students’ proportional reasoning. We used design research as the research approach. In the first cycle of the design research called as the pilot experiment, six students of 7th grade were participated. We designed a sequence of instructional activities that has mathematical problem using Palembang culture as the context such as Songket (Palembang woven cloth) and Ampera Bridge (national historic site of Palembang) and the ratio table as the model to support students’ proportional reasoning. The exploration of the proportional situation usingstudents’ daily life problems, such as Palembang culture, can make students more interested to learn mathematics and easily understand the given mathematical problems. In addition, one of the goals of the developed curriculum in Indonesia is use the local culture of Indonesia in every subject given in middle school, including in mathematics. Therefore, students have a lot of motivation and enthusiasm to solve the given problems during mathematics class. The result of this study indicatedthat using Palembang culture as the context and ratio table as the model really helped students to think proportionally. They can change students mind from using additive thinking to multiplicative thinking. Keywords: proportional reasoning, design research, Palembang culture, ratio table
