Middle School Mathematics Proposition Teaching Theory And Practice

Mathematical proposition is the mathematical basis of logical reasoning, is the manifestations of mathematics knowledge, and various of mathematical problems. The mathematical proposition knowledge firmly grasp is directly related the ability of the students to analyze and solve problems, which not only decids students mathematical thinking and mathematical methods, but also decid students learning new knowledge and new skills in future . Proposition teaching is the important contents of the high school mathematics teaching. Mathematical proposition based teaching to lecturing now, Students can only passively accept, mostly is a high mark imbecility, Only do, can't consider, did not truly reflect the quality of education , developmenting the ability of students,the Improvement of the student's interest is few.This text mainly research zhe theory and practice of mathematical proposition teaching in zhe middle schools. Purpose is to enable teachers to attach great importance to the general proposition teaching, find the current shortage of teaching, theory and practice, in order to improve the quality of teaching, reduce the homework of students, Stimulate student interest in learning,develop logical thinking ability of students and improve the mathematical literacy of students.First proposition and the proposition teaching of mathematics are introduced in this article. Including the meaning of propositions, classification, characteristics, given the significance of proposition teaching, analyze the situation at home and abroa of proposition teaching of mathematics. The next done a preliminary analysis about the theory of mathematics proposition teaching, there are three main theories: constructivist learning theory, assimilation theory of cognitive learning Ausubel and Piaget's genetic epistemology theory. Combination of these three theories, Study on the psychological analysis of Proposition, Proposition of mathematics teaching strategies is given. Finally, combined with theoretical study on the two propositions, analyzed the teaching,reached the following conclusions:The introduction phase of proposition, the original proposition in the domain of knowledge is the foundation, advance organizer materials, establish contact between the old and new knowledge, try to teach students the production of proposition, conducive to the assimilation and adapt of new and old knowledge, construction of new propositions network. Proof of proposition stage,not only consider the characteristics of students understanding,but also consider the relationship between the new proposition with the original knowledge, for different types of propositions, adopt different teaching strategies. Proposition application stage, by analogy with the relevant knowledge, variant exercises on the learning of procedural knowledge, the use of variant practice, can promote the proposition into a production system, refinement of the network to promote proposition...
