Relation between students reasoning ability towards mathematics and their achievement

Today's world has seen education as a powerful feature to achieve social and economic upward goals. Thus educational systems must concentrate on students’ abilities to stimulate then and motivated to be active individual in learning process. New movement in education systems is moving from teacher-centered into student-centered situation. Proficiency in languages, science and mathematics is seen as an essential precursor to success in modern society the knowledge of mathematics is an essential tool in our society [Baroody 1987]. Reasoning skills are an important component of education and reasoning skills are necessary for understanding mathematics in particular, and they present an important means of developing ideas. Mathematics is trigger the development of thinking ability particularly reasoning ability. This is because mathematics is knowledge which has deductive axiomatic characteristic, which need thinking ability and reasoning to understand it. Reasoning ability and achievement in mathematics were also correlated in mathematics. Thus, the reasoning is the process of thinking in conclusion. General conclusions can be drawn from the cases of the individual, or otherwise, of things that are common to be the case that individual. Sadiq (2009), Herdian (2010), defines reasoning as an activity, process or activity thought to draw conclusions or make a new statement, which was based on some statements whose truth has been proven or assumed previously.
