Student Algebraic Reasoning to Solve Quadratic Equation Problem

Abstract

The reasoning is closely related to students’ mathematical abilities. Reasoning becomes a key element in mathematics learning. The student’s reasoning habits need to be developed. Competence in algebra is important. Algebra is one branch of mathematics that an essentials role in mathematics education. Algebra was prerequisite for higher studies mathematics and science courses, and a lack of algebra skills have a chance results in poor performance in courses The purpose of this research is to describe students’ algebraic reasoning in solving quadratic equation problem. The method used in this research is descriptive qualitative. Research subjects were three students of class X. The results in the study showed that students use a different strategy in solving the problem of quadratic equations. This can make a description of the existing schema. There are also students who misunderstand the concept of understanding operations in algebra so that this can affect their reasoning process and makes their answer incorrect.
