The effect of using the model of Posner to change the mathematical concepts and second grade students Altheselldy average

Abstract

The acquisition of mathematical concepts of great importance as one of the components of mathematical knowledge that helps to understand the nature of mathematics and its development and give the teacher and the learner's scientific expertise that can enrich the knowledge structure of students by stimulating the process of mental development. From here the search is in how to communicate mathematical concepts to students that will ensure their safety in terms of form and content, and to remove any ambiguity that might get in on the other. Can students learn concepts in various stages of growth, provided that knows and representing each concept in a manner consistent with the mental development and maturity sports for the students that stage, and to benefit from this growth is sequential in the mathematical concepts as well as "growth that occurs in the human mind, it appeared some of the models for the education of and learn the concepts and mathematical principles. (Frederick, 1986, p 130). That the model of Posner - which means by this research - is one of the models that have dealt with the theme of the concept (The concept), and proposed a number "of strategies designed to bring the concepts to students properly with excitement what has been Achtzanh in the mind of the student to look superficial or wrong for this concept or the other. Accordingly, the researchers surveyed the views of some of the experienced workers in the teaching of mathematics and involved in that, and ask them about the mathematical concepts misconceptions among the students of second grade average in mathematics, has pointed to the existence of (32) concepts of "athletes" wrong "out of (72) concept "was introduced to them by the researchers with a list of mathematical concepts contained in the first five chapters of the book Mathematics for Grade average of 11 years i, 2004, the Ministry of Education, Republic of Iraq. To deal with this imbalance is clear in understanding the concept and knowledge of the implications for student achievement, identify the research question was: What is the effect of using the model of Posner to change the mathematical concepts and achievement among students in the second row of the Mediterranean?
