Improving Students' Mathematical Argumentation Skill Through Infusion Learning Strategy

This study aimed to develop infusion learning strategy to improve students' mathematical argumentation skill. One problem of mathematical learning in college was that students had low competence to solve problems, particularly in argumentation. To cope with that issue, therefore, infusion learning strategy was developed. It aimed to assist students in improving their argumentation skills. The stages of infusion learning strategy were based on theory of argument by Walton. This study applied Research & Development (R&D) method with procedures of development by Borg & Gall which had been modified into 10 stages, but it was restricted to 6^th stage. The instrument of this study used validation sheet, test of mathematical argumentation, and interview guidelines. The result referred to a valid product of infusion learning strategy which implementation could improve students' mathematical argumentation. Another result of this study found that students' argumentation skill progressed/improved.
