高一数学必修四1.5教案篇2

一、教学目标:

1.通过高速公路上的实际例子，引起积极的思考和交流，从而认识到生活中处处可以遇到变量间的依赖关系.能够利用初中对函数的认识，了解依赖关系中有的是函数关系，有的则不是函数关系.2.培养广泛联想的能力和热爱数学的态度.二、教学重点：

在于让学生领悟生活中处处有变量，变量之间充满了关系

教学难点：培养广泛联想的能力和热爱数学的态度

三、教学方法：

探究交流法

四、教学过程

(一)、知识探索：

阅读课文P25页。实例分析：书上在高速公路情境下的问题。

在高速公路情景下，你能发现哪些函数关系?

2.对问题3，储油量v对油面高度h、油面宽度w都存在依赖关系，两种依赖关系都有函数关系吗?

问题小结：

1.生活中变量及变量之间的依赖关系随处可见，并非有依赖关系的两个变量都有函数关系，只有满足对于一个变量的每一个值，另一个变量都有唯一确定的值与之对应，才称它们之间有函数关系。

2.构成函数关系的两个变量，必须是对于自变量的每一个值，因变量都有唯一确定的y值与之对应。

3.确定变量的依赖关系，需分清谁是自变量，谁是因变量，如果一个变量随着另一个变量的变化而变化，那么这个变量是因变量，另一个变量是自变量。

(二)、新课探究——函数概念

1.初中关于函数的定义：

2.从集合的观点出发，函数定义：

给定两个非空数集 A和B，如果按照某个对应关系f，对于 A中的任何一个数x，在集合B中都存在唯一确定的数f(x)与之对应，那么就把这种对应关系f叫做定义在 A上的函数，记作或 f：A→B，或y=f(x),x∈A.;

此时x叫做自变量，集合A叫做函数的定义域，集合 {f(x)︱x∈A}叫作函数的值域。习惯上我们称y是x的函数。

定义域，值域，对应法则

4.函数值

当x=a时，我们用f(a)表示函数y=f(x)的函数值。

(三)、知识体验(课堂练习及课外作业)

1.某电器商店以2000元一台的价格进了一批电视机，然后以2100元的价格售出，随着售出台数的变化，商店获得的收入是 ,它们之间是______关系.【函数 y=100x,x∈D 】

2.现实生活中,与时间存在函数关系的量_______________________.(三个以上)

【路程与时间;炮弹的射高与时间的变化关系问题;用电量与时间的关系。】

3.坐电梯时,电梯距地面的高度与时间之间存在______________关系.【函数】

4.在一定量的水中加入蔗糖,糖水的质量浓度与所加蔗糖的质量之间存在怎样的依赖关系?如果是函数关系,指出自变量和因变量.新课标第一网

【是函数关系;自变量是所加蔗糖的质量;因变量是糖水的质量浓度。】

5.日期与星期之间存在怎样的依赖关系?这种依赖关系是函数关系吗?如果是,指出自变量和因变量.【是函数关系;自变量是日期;因变量是星期。】

6.下列过程中变量之间是否存在依赖关系,其中哪些是函数关系:

(2)在空中作斜抛运动的铅球,铅球距地面的高度与时间的关系;

(3)某水文观测点记录的水位与时间的关系;

(4)某十字路口,通过汽车的数量与时间的关系;

(5)等边三角形的边长与面积之间的关系.7.下列各式是否表示y是x的函数关系?如果是,写出这个函数的解析式。

(1)5x+2y=1(x R);

(2)xy=-3(x 0);

(3)(x(-1,0))

教学主案（教学内容）教学辅案

（教学方法、手段、活动）

一、导人新课

每个人都渴望成为一个有知识的人，每个人都渴望成为一个有修养的人。那么获取知识的途径是什么？提高修养的途径又是什么呢？答案有一个，就是学习。其实，学会学习也是一种学习，优秀的学习品质本身就是一种修养。相信两千多年前荀子所作的《劝学》会对我们学会学习和培养我们的学习品质从而提高我们的学习修养有所启发。今天，就让我们走进这篇流传千古的佳作。

二、简介作者与文题：

1、荀子（约前313-前238）名况，字卿，战国末期赵国人。著名的思想家、教育家。曾游学于齐国、秦国、楚国，韩非、李斯都是他的学生。荀子是先秦儒家的最后代表人物，提出了“人性本恶”的观点，但强调后天的环境和教育可以改变人性中的“恶”，因此，他特别重视人的学习，重视教育的作用。

他认为人类天生有欲求，有欲求必有争夺，任其天性发展，必做恶事，因此他提出“性恶论”，强调发挥教育和礼法的作用，认为“今之人性恶，必将待师法然后正，得礼义然后治”。认为人和物都可以改变，能改造好，能“知明而行无过”。

《劝学》是《荀子》的第一篇，是荀子教学思想的专论，比较全面而系统地论述了他对教育

和学习的一系列观点和主张。本文是节选原文前四节

2、解题：

《劝学》的“劝”起着统领全篇的作用。

劝：“劝勉”的意思。

繁体字“勸”字，凡是用“力”作形旁的字，多数有给人们勉励的意思，如“励”、“努”等。这是“劝”的本义，而在现代汉语中，“劝”，解释为“劝阻”，词义已经转移了。作者在这篇以《劝学》为题目的文章中，勉励人们要不停止地坚持学习，只有这样才能增长知识，发展才能，培养高尚的品德。

三、朗读课文，整体感知：

1、教师范读，提示学生注意老师发音、重读、断句。

輮róu通煣有yòu通又知zhì是“智”的古字

暴pù已是“曝”的古字生xìng通性

2、学生自由朗读，注意读准字音，把握朗读节奏。

四、合作探究，疏通文意

第1段，提出中心论点。

君子曰：学不可以已。(已，停止)

第2段

重点实词

取之于蓝：提取/蓝草

木直中绳：合乎

其曲中规：

参省乎己：省察，反省

知明而行无过：明达

虚词

取之于蓝，而青于蓝：从/但是/比

君子博学而日参省乎己:并且；于，解释为对

虽有槁暴：即使

通假字

輮以为轮：“輮”通“煣”使------弯曲

虽有槁暴：“有”通“又”;“暴”通“曝”曝晒

则知明而行无过矣：“知”通“智”智慧

特殊句式

虽有槁暴，不复挺者，輮使之然也判断句

青，取之于蓝介词短语后置

輮以为轮省略句

君子博学而日参省乎已状语后置

第2段，阐明学习的重要意义。作者用了五个比喻。“青出于蓝”、“冰寒于水”，说明事物经过一定的变化，可以提高。

“直木为轮”说明事物经过一定的变化，还可以改变原来的状态。“木受绳则直”、“金就砺则利” 说明：肯下功夫。必见成效。

——推论出人必须通过学习和参省才能达到“知明而行无过”的境地。本段是从总论学习的重要性这个角度来论述中心论点的。

五、巩固：学生自读课文，自行口译，要能字句落实。学生提问不明白的问题，教师解答。

六、布置作业：背诵全文；完成书后练习。

高一必修四教案篇6

Good morning，It’s my great pleasure to be here sharing my lesson with you. In the reading process, I will focus on students’ long-term development and enable them to use proper reading skills and strategies. In other words, students are guided to read efficiently and independently.

I’ll be ready to divide my draft into five parts.. Analysis of the teaching material, the teaching methods, the studying methods, the teaching procedure, and Blackboard design. First, let me talk about the teaching material.

Section 1 Analysis of the teaching material

The selected teaching material is a business proposal taken from the Reading section of Unit 3, Module 4 of Advance with English. This unit explores the theme of the future and tomorrow’s world. It provides a chance for students to gain a better understanding of the future and to imagine what they think will happen in the future and to imagine what they think will happen in the future with the rapid development of science and technology . As for the reading text, it is a business proposal which introduces a virtual reality cinema called RealCine, a new high-tech form of cinema.

As we all know, reading belongs to the input during the process of the language learning. The input has great effect on output, such as speaking and writing. According to the New Standard Curriculum, after studying the teaching material and analyzing the rule of children’s growing of mind, I think the teaching aims are the followings:

1. Knowledge objects:

1. Students are required to learn some information about how this product works, why it is better than ordinary cinema, and how it can be used in many other ways.

2. Students are expected to know that the language for a proposal should be clear and persuasive, the information should be detailed and convincing, and the author needs to be objective.

2. Ability objects:

Students are expected to master this strategy and become more competent in reading a business proposal.

3. Emotion or moral objects:

By completing the task, the Ss increase their interest in science and technology and prepare to make contributions to the development of science.

Now, let’s come to the important points and the difficult points.

1. Be familiar with VR.

2. Have a debate on VR successfully.

Section 2 Analysis of the teaching methods

In my opinion, the main aims of learning English in the Middle School is to develop the students’ abilities of listening, speaking, reading, writing and their good sense of the English language. So in this lesson I’ll mainly use “Task-based” language teaching. That is to say, students are the master of our class and they will do things with English in my class.

Section 3 Analysis of the studying methods

Generally speaking, students in our class don’t pay enough attention to English learning. They are poor in cooperative learning skills. Some students are not active in the class, and some students don’t like English. Therefore. However, we teachers should try to develop their ability. The students will work in group to discuss and finish the given tasks. They can show what they have learned to their partners in the group. At last, they will have a debate about RealCine.

Section 4 Teaching Procedure

Step 1 Lead -in

Show several extras from the film Avatar to students and ask them the following questions:

1．Do you like it？

2．Do you feel it exciting if you are actually in the film? Why?

【设计说明】由于课文中所提到的“RealCine”在现实生活中还不存在，因此，学生较难对这一概念产生直观感受。从学生熟悉的电影片段出发，用两个问题层层递进，引出3D最终引出“RealCine”这一概念，可以激发学生的学习兴趣。

Step 2 Check preview-work

1. What is the name of the product? And what technology is behind this product?

2. What is the difference between Realcine and ordinary cinema?

3. What is the disadvantage(缺点) of VR ?

Step 3 Reading strategy: reading a business proposal

A business proposal is____________________________________________.A good proposal has to be ________ and __________. It usually includes __________________ and _____________ or____________.

【设计说明】读阅读策略，在后文章体会特点。

Step 4 Reading comprehension :( fast-reading)

a Realcine, which excites all five of people’s senses, is different from ordinary cinema.

b. VR can provide people with another way to experience the world.

c. An argument about Realcine has come up.

d. A brief introduction to the new technology– Realcine .

e. We should admit that Realcine is a good opportunity for film-making.

f. The senses of smell and taste can also be satisfied.

g. How does Realcine work?

Step 6 Debate

Tell students that different people hold different opinions towards RealCine.

Opinion 1:

Those who support virtual reality believe that, with this technology, people can do almost everything, even things that cannot be realized in normal life. We don’t need to travel any more or spend so much time with friends any more. Virtual reality can provide any necessary features that we need in our life.

Opinion 2:

Others insist that real life and interpersonal communication should never be replaced by imaginary scenes. People should take off the headsets and experience the real life themselves.

Ask students which one they support and why.

Divide students into two groups and have a debate. The group with the most supporting proofs or evidences wins.
