《平面的法向量与平面的向量表示》教学设计（The teaching design of the normal vector and plane vector representation of plane） The teaching design of the normal vector and plane vector representation of plane Changtu no.3 high school dong lihua 1. Textbook description: human education B version of normal high school curriculum standard experimental textbook (optional 2-1) Class: new lecture Class: 1 hour Four, learning analysis: this section before students have mastered space vector and operations, use the method of vector linear parallel to the line, line and plane parallel to the plane parallel to the plane, vertical and use vector to prove two straight lines or for two straight lines into the corner. Can use vector method to deal with some geometric problems. There are some general ways to solve geometrical problems with vectors. Students like to use the analogy, the special to the general way of thinking to explore the problem. Some students have to improve their ability to summarize and summarize. Five, teaching material analysis: in this section, the knowledge taught B version of the ordinary high school curriculum standard experiment textbook elective third chapter 2-1 the space vector and the three-dimensional geometry in the second quarter of the space vector in the application of solid geometry in the second part of the normal vector of plane and plane vector representation , an important part of vector used in solid geometry. This section is mainly the application of normal vector and normal vector. Vector method is used to solve the linear and linear problems, and the vector operation is used to prove the relationship between geometric position and vector relationship. It is the concrete representation of geometrical problem with vector method. The normal vector of plane is the bridge to solve the problem of space Angle and space distance. (1) understanding the concept of plane normal vector and the normal vector of plane; (2) to understand the application of planar normal ve
