Teaching Research And Teaching Design On "Selective Lecture Of Inequality"

In recent years,with the deepening of the curriculum reform,high school textbooks are constantly updated,research about the new curriculum experiment is more and more popular.in ordinary high school mathematics curriculum standards(here in after referred to as<the standard>)will be part of the inequality in the original basis added the Cauchy inequality,linear programming,sequencing inequality,mathematics the inductive method,reduction to absurdity and scaling law,and the inequality part is divided into two parts,one part in compulsory 5,another part in elective 4-5 this paper aimed at<selecting the topic to do>inequality of teaching and research and teaching design according to the research results.Inequality based knowledge framework of middle school,is a powerful tool to solve other problems,to cultivate students' logical thinking ability,reasoning ability are of great help,if teachers can make full use of the advantages of inequality,inequality will be a thorough look at the role of,can guide students to apply their knowledge,real will to resolve inequality process into a kind of mathematical thought,can cultivate the innovative spirit and truly high-quality talents.Therefore,to enable students to master the core idea of inequality is of great significance.This paper mainly from the perspective of middle school mathematics teaching in middle school,based on the on-the-spot investigation to understand The teaching status of inequality,and then according to the research results and the classification of the college entrance examination questions are pertinent teaching suggestions,and make the teaching design of physical and mental development of students and the relevant educational theory,this article can make research in the middle school mathematics inequality make corresponding contributions in the study.
