Identifying Students’ Mathematical Argumentation Competence in Solving Cubes and Pyramid Problems

Abstract

Abstract This article aimed to describe students’ mathematical argumentation competence in solving cubes and pyramid problems. The kind of problem to be solved in this study referred to proving. The students’ mathematical arguments were thoroughly analyzed using Toulmin scheme. It used qualitative method. The data was collected by asking 40 students to do argumentation task by thinking out loud strategy. The subject’s works would be compared to the problem structure based on the Toulmin scheme. From data analysis, it found three kinds of mathematical arguments the students had made to solve cubes and pyramid problems. Those three mathematical arguments were inductive-incomplete, inductive-complete, and deductive arguments.
