Supporting Students' Reasoning and Argumentation Skills Through Mathematical Literacy Problem on Relation and Function Topic

Reasoning and argumentation skills are one of the fundamental mathematical abilities used in mathematical literacy. This ability can be taught to students through mathematics teaching. It involves a process of logical and profound thinking through a process that connects the problem elements to make a conclusion. This research aimed to describe how to support students' reasoning and argumentation through mathematical literacy problem on function and relation. The research was conducted through the observation of mathematic class of Junior High School on function and relation topic by scientific approach, and the assignment of mathematical literacy problem solving through student worksheet. Then the data were analyzed by descriptive qualitatively to describe the teaching process and students' reasoning and argumentation. The data of this research indicate that mathematical literacy problems presented through scientific approach, discovery learning and problem based learning can support students' reasoning and argumentation on function and relation topic on Junior High School.
