课题选自教材:人教版(A版)《普通高中课程标准实验教科书·数学必修2》,2.3.1直线与平面垂直的判定。下面,我将分别从教学内容分析、学生情况分析、教学目标设计、教学策略设计四个方面对这节课的第一课时进行分析和说明。一、教学内容分析本节课主要学习直线与平面垂直的定义、判定定理及其初步运用。任何定义都有充分必要性,线面垂直的定义既是线面垂直最基本的判定方法,又是它的重要性质,也是探究线面垂直判定 Topic selected from the textbook: PEP (A) “ordinary high school curriculum standard experimental textbook math compulsory 2”, 2.3.1 straight line and plane vertical decision. Next, I will analyze and explain the first lesson of this lesson from four aspects: teaching content analysis, student situation analysis, teaching goal design, and teaching strategy design. First, the teaching content analysis This lesson mainly to learn the definition of straight and vertical plane, the judgment theorem and its initial application. The definition of line surface is both the most basic determination method of line surface vertical and the important property of it, as well as the vertical line determination
