中学数学说课稿（Middle school mathematics Lecture Note）

中学数学说课稿（Middle school mathematics Lecture Note） A group of inequalities releases Analysis of the teaching materials: Zhejiang for the eight grade fifth chapter 5.1 understanding the 5.2 basic properties of inequality, inequality, 5.3 yuan a 5.4 yuan a inequality, inequality. Let the students know the basic nature of understanding inequality, inequality, grasp a inequality and a Inequalities Solution and one inequality and unary inequalities application. Two, analysis of the target: 1. knowledge: understanding inequality, understand the nature of inequality. 2. ability: inequality and using inequality to solve practical problems. Three. The heavy and difficult analysis: 1. teaching points: (1) solution of inequality and inequalities. (2) the use of inequalities to solve practical problems. 2. teaching difficulties: set said in axis on the significance and solution of a inequality inequality set. Methods: by observing the breakthrough teaching difficulty, analysis, summary, to enable students to set inequalities have a preliminary understanding, and then through the axis is clearly shown that the solution set of inequalities, so as to deepen students understanding of the solution set of inequalities. Four senior high school entrance examination test analysis: Compare the size of 1. 2. quadratic function related coefficient a, B, a number of radio appear form of C choice. Discuss the 3. quadratic equation with one unknown number of root and the number of parabola and straight intersection. 4. for one yuan a set of solutions of the inequality and said solution set on the axis. 5. using the inequality range range of function arguments and function value. Especially the range of independent variables in piecewise function. The use of 6. inequalities in program design in the title. Five, teaching analysis: as the personalized tutoring center and school classes are different, so in essence, counseling process inequality chapters to the students, the school should change the
