人教A版高中數(shù)學必修一指數(shù)函數(shù)的概念教學設計（2）
指數(shù)函數(shù)與冪函數(shù)是相通的，本節(jié)在已經(jīng)學習冪函數(shù)的基礎上通過實例總結歸納指數(shù)函數(shù)的概念，通過函數(shù)的三個特征解決一些與函數(shù)概念有關的問題.課程目標1、通過實際問題了解指數(shù)函數(shù)的實際背景；2、理解指數(shù)函數(shù)的概念和意義.數(shù)學學科素養(yǎng)1.數(shù)學抽象：指數(shù)函數(shù)的概念；2.邏輯推理：用待定系數(shù)法求函數(shù)解析式及解析值；3.數(shù)學運算：利用指數(shù)函數(shù)的概念求參數(shù)；4.數(shù)學建模：通過由抽象到具體，由具體到一般的思想總結指數(shù)函數(shù)概念.重點：理解指數(shù)函數(shù)的概念和意義；難點：理解指數(shù)函數(shù)的概念．教學方法：以學生為主體，采用誘思探究式教學，精講多練。教學工具：多媒體。一、 情景導入在本章的開頭，問題（1）中時間 與GDP值中的 ,請問這兩個函數(shù)有什么共同特征.要求：讓學生自由發(fā)言，教師不做判斷。而是引導學生進一步觀察.研探.
人教A版高中數(shù)學必修二立體圖形直觀圖教學設計
1.直觀圖：表示空間幾何圖形的平面圖形，叫做空間圖形的直觀圖直觀圖往往與立體圖形的真實形狀不完全相同，直觀圖通常是在平行投影下得到的平面圖形2.給出直觀圖的畫法斜二側畫法觀察：矩形窗戶在陽光照射下留在地面上的影子是什么形狀？眺望遠處成塊的農(nóng)田，矩形的農(nóng)田在我們眼里又是什么形狀呢？3. 給出斜二測具體步驟（1）在已知圖形中取互相垂直的X軸Y軸，兩軸相交于O，畫直觀圖時，把他們畫成對應的X'軸與Y'軸，兩軸交于O'。且使∠X'O'Y'=45°（或135°）。他們確定的平面表示水平面。（2）已知圖形中平行于X軸或y軸的線段，在直觀圖中分別畫成平行于X'軸或y'軸的線段。（3）已知圖形中平行于X軸的線段，在直觀圖中保持原長度不變，平行于Y軸的線段，在直觀圖中長度為原來一半。4.對斜二測方法進行舉例：對于平面多邊形，我們常用斜二測畫法畫出他們的直觀圖。如圖 A'B'C'D'就是利用斜二測畫出的水平放置的正方形ABCD的直觀圖。其中橫向線段A'B'=AB，C'D'=CD；縱向線段A'D'=1/2AD，B'C'=1/2BC；∠D'A'B'=45°，這與我們的直觀觀察是一致的。5.例一：用斜二測畫法畫水平放置的六邊形的直觀圖(1)在六邊形ABCDEF中，取AD所在直線為X軸，對稱軸MN所在直線為Y軸，兩軸交于O'，使∠X'oy'=45°（2）以o'為中心，在X'上取A'D'=AD，在y'軸上取M'N'=½MN。以點N為中心，畫B'C'平行于X'軸，并且等于BC；再以M'為中心，畫E'F'平行于X‘軸并且等于EF。 （3）連接A'B',C'D',E'F',F'A',并擦去輔助線x軸y軸，便獲得正六邊形ABCDEF水平放置的直觀圖A'B'C'D'E'F' 6. 平面圖形的斜二測畫法（1）建兩個坐標系，注意斜坐標系夾角為45°或135°；（2）與坐標軸平行或重合的線段保持平行或重合；（3）水平線段等長，豎直線段減半；（4）整理.簡言之：“橫不變，豎減半，平行、重合不改變?！?/p>
人教A版高中數(shù)學必修二平面與平面平行教學設計
1.探究：根據(jù)基本事實的推論2,3，過兩條平行直線或兩條相交直線，有且只有一個平面，由此可以想到，如果一個平面內(nèi)有兩條相交或平行直線都與另一個平面平行，是否就能使這兩個平面平行？如圖（1），a和b分別是矩形硬紙板的兩條對邊所在直線，它們都和桌面平行，那么硬紙板和桌面平行嗎？如圖（2），c和d分別是三角尺相鄰兩邊所在直線，它們都和桌面平行，那么三角尺與桌面平行嗎？2.如果一個平面內(nèi)有兩條平行直線與另一個平面平行，這兩個平面不一定平行。我們借助長方體模型來說明。如圖，在平面A’ADD’內(nèi)畫一條與AA’平行的直線EF,顯然AA’與EF都平行于平面DD’CC’,但這兩條平行直線所在平面AA’DD’與平面DD’CC’相交。3.如果一個平面內(nèi)有兩條相交直線與另一個平面平行，這兩個平面是平行的，如圖，平面ABCD內(nèi)兩條相交直線A’C’,B’D’平行。
人教A版高中數(shù)學必修二事件的相互獨立性教學設計
問題導入：問題一：試驗1：分別拋擲兩枚質地均勻的硬幣，A=“第一枚硬幣正面朝上”，B=“第二枚硬幣正面朝上”。事件A的發(fā)生是否影響事件B的概率？因為兩枚硬幣分別拋擲，第一枚硬幣的拋擲結果與第二枚硬幣的拋擲結果互相不受影響，所以事件A發(fā)生與否不影響事件B發(fā)生的概率。問題二：計算試驗1中的P(A),P(B),P(AB)，你有什么發(fā)現(xiàn)？在該試驗中，用1表示硬幣“正面朝上”，用0表示“反面朝上”，則樣本空間Ω={（1，1），（1，0），（0，1），（0，0）}，包含4個等可能的樣本點。而A={（1，1），（1，0）}，B={（1，0），（0，0）}所以AB={（1，0）}由古典概率模型概率計算公式，得P(A)=P(B)=0.5，P(AB)=0.25， 于是 P(AB)=P(A)P(B)積事件AB的概率恰好等于事件A、B概率的乘積。問題三：試驗2：一個袋子中裝有標號分別是1，2，3，4的4個球，除標號外沒有其他差異。

1.圓柱、圓錐、圓臺的表面積與多面體的表面積一樣，圓柱、圓錐、圓臺的表面積也是圍成它的各個面的面積和。利用圓柱、圓錐、圓臺的展開圖如圖，可以得到它們的表面積公式：2.思考1：圓柱、圓錐、圓臺的表面積之間有什么關系？你能用圓柱、圓錐、圓臺的結構特征來解釋這種關系嗎？3.練習一圓柱的一個底面積是S，側面展開圖是一個正方體，那么這個圓柱的側面積是（ ）A 4πS B 2πS C πS D 4.練習二：如圖所示，在邊長為4的正三角形ABC中，E，F(xiàn)分別是AB，AC的中點，D為BC的中點，H，G分別是BD，CD的中點，若將正三角形ABC繞AD旋轉180°，求陰影部分形成的幾何體的表面積．5. 圓柱、圓錐、圓臺的體積對于柱體、錐體、臺體的體積公式的認識(1)等底、等高的兩個柱體的體積相同．(2)等底、等高的圓錐和圓柱的體積之間的關系可以通過實驗得出，等底、等高的圓柱的體積是圓錐的體積的3倍．

新知探究：向量的減法運算定義問題四：你能根據(jù)實數(shù)的減法運算定義向量的減法運算嗎？由兩個向量和的定義已知 即任意向量與其相反向量的和是零向量。求兩個向量差的運算叫做向量的減法。我們看到，向量的減法可以轉化為向量的加法來進行：減去一個向量相當于加上這個向量的相反向量。即新知探究（二）：向量減法的作圖方法知識探究（三）：向量減法的幾何意義問題六：根據(jù)問題五，思考一下向量減法的幾何意義是什么？問題七：非零共線向量怎樣做減法運算？ 問題八：非零共線向量怎樣做減法運算？1.共線同向2.共線反向小試牛刀判一判(正確的打“√”，錯誤的打“×”)(1)兩個向量的差仍是一個向量。 (√ )(2)向量的減法實質上是向量的加法的逆運算.

1.觀察（1）如圖，在陽光下觀察直立于地面的旗桿AB及它在地面影子BC,旗桿所在直線與影子所在直線的位置關系是什么？（2）隨著時間的變化，影子BC的位置在不斷的變化，旗桿所在直線AB與其影子B’C’所在直線是否保持垂直？經(jīng)觀察我們知道AB與BC永遠垂直，也就是AB垂直于地面上所有過點B的直線。而不過點B的直線在地面內(nèi)總是能找到過點B的直線與之平行。因此AB與地面上所有直線均垂直。一般地，如果一條直線與一個平面α內(nèi)所有直線均垂直，我們就說l垂直α，記作l⊥α。2.定義：①文字敘述：如果直線l與平面α內(nèi)的所有 直線都垂直，就說直線l與平面α互相垂直，記作l⊥α.直線l叫做平面α的垂線，平面α叫做直線l的垂面．直線與平面垂直時，它們唯一的公共點P叫做交點．②圖形語言：如圖．畫直線l與平面α垂直時，通常把直線畫成與表示平面的平行四邊形的一邊垂直．③符號語言：任意a?α，都有l(wèi)⊥a?l⊥α.

新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學設計
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.
