拋物線及其標準方程教學設(shè)計人教A版高中數(shù)學選擇性必修第一冊
本節(jié)課選自《2019人教A版高中數(shù)學選擇性必修第一冊》第二章《直線和圓的方程》，本節(jié)課主要學習拋物線及其標準方程在經(jīng)歷了橢圓和雙曲線的學習后再學習拋物線，是在學生原有認知的基礎(chǔ)上從幾何與代數(shù)兩 個角度去認識拋物線.教材在拋物線的定義這個內(nèi)容的安排上是：先從直觀上認識拋物線，再從畫法中提煉出拋物線的幾何特征，由此抽象概括出拋物線的定義，最后是拋物線定義的簡單應(yīng)用.這樣的安排不僅體現(xiàn)出《課程標準》中要求通過豐富的實例展開教學的理念，而且符合學生從具體到抽象的認知規(guī)律，有利于學生對概念的學習和理解.坐標法的教學貫穿了整個“圓錐曲線方程”一章，是學生應(yīng)重點掌握的基本數(shù)學方法 運動變化和對立統(tǒng)一的思想觀點在這節(jié)知識中得到了突出體現(xiàn)，我們必須充分利用好這部分教材進行教學
雙曲線及其標準方程教學設(shè)計人教A版高中數(shù)學選擇性必修第一冊
∵在△EFP中,|EF|=2c,EF上的高為點P的縱坐標,∴S△EFP=4/3c2=12,∴c=3,即P點坐標為(5,4).由兩點間的距離公式|PE|=√("(" 5+3")" ^2+4^2 )=4√5,|PF|=√("(" 5"-" 3")" ^2+4^2 )=2√5,∴a=√5.又b2=c2-a2=4,故所求雙曲線的方程為x^2/5-y^2/4=1.5.求適合下列條件的雙曲線的標準方程.(1)兩個焦點的坐標分別是(-5,0),(5,0),雙曲線上的點與兩焦點的距離之差的絕對值等于8;(2)以橢圓x^2/8+y^2/5=1長軸的端點為焦點,且經(jīng)過點(3,√10);(3)a=b,經(jīng)過點(3,-1).解:(1)由雙曲線的定義知,2a=8,所以a=4,又知焦點在x軸上,且c=5,所以b2=c2-a2=25-16=9,所以雙曲線的標準方程為x^2/16-y^2/9=1.(2)由題意得,雙曲線的焦點在x軸上,且c=2√2.設(shè)雙曲線的標準方程為x^2/a^2 -y^2/b^2 =1(a>0,b>0),則有a2+b2=c2=8,9/a^2 -10/b^2 =1,解得a2=3,b2=5.故所求雙曲線的標準方程為x^2/3-y^2/5=1.(3)當焦點在x軸上時,可設(shè)雙曲線方程為x2-y2=a2,將點(3,-1)代入,得32-(-1)2=a2,所以a2=b2=8.因此,所求的雙曲線的標準方程為x^2/8-y^2/8=1.當焦點在y軸上時,可設(shè)雙曲線方程為y2-x2=a2,將點(3,-1)代入,得(-1)2-32=a2,a2=-8,不可能,所以焦點不可能在y軸上.綜上,所求雙曲線的標準方程為x^2/8-y^2/8=1.

Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.

人教版高中英語必修4A taste of English Humor說課稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.

3、文化是人們的一種素養(yǎng)（1）人的文化素養(yǎng)是在社會生活、實踐中形成的。每個人所具有的文化素養(yǎng)，不是天生的，而是通過對社會生活的體驗，特別是通過參與文化生活、接受知識文化教育而逐步培養(yǎng)出來的。文化素養(yǎng)的形成，離不開生活、實踐和教育。人們在社會實踐中創(chuàng)造和發(fā)展文化，也在社會生活中獲得和享用文化。（2）人的文化素養(yǎng)表現(xiàn)在日常言行中。教師活動：引導學生閱讀教材7頁“公交車漫畫”材料，并思考所反映的問題學生活動：積極思考并討論問題教師點評：人們的精神活動離不開物質(zhì)活動，人們的文化素養(yǎng)總是要通過他在日常生活中的言行、在社會實踐活動中的表現(xiàn)等表現(xiàn)出來。我們通過觀察人們的社會行為，就可以從中透視人們的精神世界和精神生活。4、文化的傳承和發(fā)展離不開物質(zhì)載體。社會文化和精神產(chǎn)品離不開物質(zhì)載體，一個時代的文化和精神產(chǎn)品，往往是這一時代社會發(fā)展軌跡的反映。
