人教A版高中数学必修二向量的减法运算教学设计
新知探究：向量的减法运算定义问题四：你能根据实数的减法运算定义向量的减法运算吗？由两个向量和的定义已知 即任意向量与其相反向量的和是零向量。求两个向量差的运算叫做向量的减法。我们看到，向量的减法可以转化为向量的加法来进行：减去一个向量相当于加上这个向量的相反向量。即新知探究（二）：向量减法的作图方法知识探究（三）：向量减法的几何意义问题六：根据问题五，思考一下向量减法的几何意义是什么？问题七：非零共线向量怎样做减法运算？ 问题八：非零共线向量怎样做减法运算？1.共线同向2.共线反向小试牛刀判一判(正确的打“√”，错误的打“×”)(1)两个向量的差仍是一个向量。 (√ )(2)向量的减法实质上是向量的加法的逆运算. ( √ )(3)向量a与向量b的差与向量b与向量a的差互为相反向量。 ( √ )(4)相反向量是共线向量。 ( √ )
人教A版高中数学必修二直线与平面垂直教学设计
1.观察（1）如图，在阳光下观察直立于地面的旗杆AB及它在地面影子BC,旗杆所在直线与影子所在直线的位置关系是什么？（2）随着时间的变化，影子BC的位置在不断的变化，旗杆所在直线AB与其影子B’C’所在直线是否保持垂直？经观察我们知道AB与BC永远垂直，也就是AB垂直于地面上所有过点B的直线。而不过点B的直线在地面内总是能找到过点B的直线与之平行。因此AB与地面上所有直线均垂直。一般地，如果一条直线与一个平面α内所有直线均垂直，我们就说l垂直α，记作l⊥α。2.定义：①文字叙述：如果直线l与平面α内的所有 直线都垂直，就说直线l与平面α互相垂直，记作l⊥α.直线l叫做平面α的垂线，平面α叫做直线l的垂面．直线与平面垂直时，它们唯一的公共点P叫做交点．②图形语言：如图．画直线l与平面α垂直时，通常把直线画成与表示平面的平行四边形的一边垂直．③符号语言：任意a?α，都有l⊥a?l⊥α.

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分，只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition

Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers!

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3.
