Reasoning Behaviors of Mathematics Difficulties Students in Solving Multiplication Integers

摘要

Behavior is an action to be performed, in learning behavioral math can be interpreted as a way of student action when solving problems. Reasoning is one part of the thinking process of students to drawing a conclusions from a problem. Reasoning behavior students has been attracted many researchers to assess the development of students' mathematical thinking. in problem solving that ends in conclusion. The ability of reasoning acts an important role for students to learn mathematics. The purpose of this study is to investigate reasoning behaviors of the grade 6th students with mathematical difficulties in solving problems of integer multiplication operations. The sample of this qualitative study was the 5th grade students in Madiun, East Java. All students were given the multiplication test from which students with mathematical difficulties were indicated. Furthermore, three volunteer students were selected as the research subjects, and were interviewed based on their answer. Two students have difficulties when word problems solving and one subject has problems when in the problem solving stage. When solving the word problems, two subjects were not able to describe the known and the way to determine the solution. The subject with low ability had no an idea how to solve the problem. The third subject had implemented an incorrect concepts in solving the problems. Even though take more time, by applying both a structured-scaffolding and learning methods that fit the problem can be overcome. This study emphasizes that lack understanding of mathematical concepts and reasoning abilities could be handled for any MD's student by implementing the structured-scaffolding based on visualized media.
