Analysis of student's mathematical reasoning ability materials quadratic equation on selected topics subject of secondary school

Abstract

The purpose of this research is to know the students mathematical reasoning ability in solving on the concept quadratic equation on Selected Topics Subject of Secondary School in terms of initial students mathematical ability. This research uses qualitative approach with descriptive research type. Sources of data used in this study is a sixth semester students of Mathematics Education FIP UMJ. Technique of collecting data through written test and interview. Based on the result of the research, it can be concluded that First, students with high initial ability categories have a tendency to use inductive and deductive reasoning elements well. Students can solve the problem of quadratic equations in the form of story problems in accordance with the steps of problem solving. Second, students with the medium initial ability categories have a tendency to use inductive and deductive reasoning elements well, but are less able to determine other ways to find answers. Third, students with low initial ability categories have a tendency to use inductive and deductive reasoning elements less well. Students are less able to solve the problem of quadratic equations according to problem solving steps and unable to determine other ways to find answers.
