Middle School Mathematics Proposition Teaching Theory And Practice

Content:Mathematical proposition is the sentence which is used to judge the object in mathematics, including the domain, quantifier, hypothesis and conclusion. According to the nature of mathematical proposition, it can be divided into true proposition and false proposition; according to the complexity, it can be divided into simple and complex proposition; according to the relationship between the various propositions, it also can be divided into the primary, converse, negated and converse-negated propositions. The teaching of proposition is the most important part in math teaching. It is benefit for the ability of students' solving problems, and also good for students'logical thinking, reasonable and language ability. Recently, there are a lot of problems in the teaching of mathematical proposition, such as the lack of integration of theory and practice, lack of teaching strategies used, and so on. Thus, this article included from four aspects, and put forward several strategies based on my practical experience. First, this article describes the constructivist learning theory, meaningful learning theory, and the basic principles of geneticep ist emology. Under the guidance in the event of epistemology, the paper that the process of teaching in the proposition, teachers need the level of cogni tive development of students, based on the proposition to enhance the students understa nding of math and actively play the role of teachers in teaching, to keep teachers and stu dents, effective two-way interaction between life and life. In addition, the mathematical proposition for students learning needs of teachers to provide effective mental activity s cenarios. Then by proposition acquisition, proposition reasoning, application of three pr opositions in Middle School Mathematics Proposition psychological process of learning is analyzed. Then, this paper studies and relevant experience in the theory based on the proposition of how to introduce, promote student understanding of the proposition, the p roposition for the students and help students grasp the proposition put forward the corre sponding policy recommendations. That you can practice or experiment, reasoning that 1 aw, Proposition deformation, and contradictions, "and other strategies to introduce prop ositions; through the structural analysis of the proposition, the class of rational use of" a dvance organizers "strategy, which can effectively help students understand the proposit ion; through the careful organization of instruction, teaching and the appropriate contac ts for example, can effectively promote student mastery of the new proposition; organiz e an effective review, pay attention to course content and teaching interest in the order o f excitation, etc., can effectively promote students proposition memory. Finally, this pap er two practical cases, a brief description of how to use modern teaching theory proposit ion teaching.
