人教A版高中數(shù)學必修二空間點、直線、平面之間的位置關(guān)系教學設(shè)計
9.例二：如圖，AB∩α=B,A?α， ?a.直線AB與a具有怎樣的位置關(guān)系？為什么？解：直線AB與a是異面直線。理由如下：若直線AB與a不是異面直線，則它們相交或平行，設(shè)它們確定的平面為β，則B∈β， 由于經(jīng)過點B與直線a有且僅有一個平面α，因此平面平面α與β重合，從而 , 進而A∈α，這與A?α矛盾。所以直線AB與a是異面直線。補充說明：例二告訴我們一種判斷異面直線的方法：與一個平面相交的直線和這個平面內(nèi)不經(jīng)過交點的直線是異面直線。10. 例3 已知a，b，c是三條直線，如果a與b是異面直線，b與c是異面直線，那么a與c有怎樣的位置關(guān)系？并畫圖說明．解： 直線a與直線c的位置關(guān)系可以是平行、相交、異面．如圖(1)(2)(3)．總結(jié)：判定兩條直線是異面直線的方法(1)定義法：由定義判斷兩條直線不可能在同一平面內(nèi)．

由于三角函數(shù)是刻畫周期變化現(xiàn)象的數(shù)學模型，這也是三角函數(shù)不同于其他類型函數(shù)的最重要的地方，而且對于周期函數(shù)，我們只要認識清楚它在一個周期的區(qū)間上的性質(zhì)，那么它的性質(zhì)也就完全清楚了，因此本節(jié)課利用單位圓中的三角函數(shù)的定義、三角函數(shù)值之間的內(nèi)在聯(lián)系性等來作圖，從畫出的圖形中觀察得出五個關(guān)鍵點，得到“五點法”畫正弦函數(shù)、余弦函數(shù)的簡圖．課程目標1.掌握“五點法”畫正弦曲線和余弦曲線的步驟和方法，能用“五點法”作出簡單的正弦、余弦曲線.2.理解正弦曲線與余弦曲線之間的聯(lián)系. 數(shù)學學科素養(yǎng)1.數(shù)學抽象：正弦曲線與余弦曲線的概念； 2.邏輯推理：正弦曲線與余弦曲線的聯(lián)系； 3.直觀想象：正弦函數(shù)余弦函數(shù)的圖像； 4.數(shù)學運算：五點作圖； 5.數(shù)學建模：通過正弦、余弦圖象圖像，解決不等式問題及零點問題，這正是數(shù)形結(jié)合思想方法的應(yīng)用.

人教A版高中數(shù)學必修二立體圖形直觀圖教學設(shè)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(cè)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(yīng)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(shè)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(shè)計
問題導入：問題一：試驗1：分別拋擲兩枚質(zhì)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(jié)果與第二枚硬幣的拋擲結(jié)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。

新人教版高中英語必修2Unit 1 Cultural Heritage-Reading and Thinking教案一
The theme of the reading and thinking is about “Understanding how a problem was solved”.The Listening & Speaking & Talking is about international co-work to protect the Mount Tai, in which the students from seven countries came up with many solutions even create the Mount Tai App. This section aims at showing how to solve a difficult and even tough problem about protecting the cultural heritage by the international co-work. So in this section, cultivating students’ international awareness is very clear and important. Concretely, with the economic development, how to balance the protection of cultural relics and social development is a big challenge for human. In the 1950s, the Egyptian government wanted to build the Aswan Dam across the Nile to control floods, produce electricity and water farms. But the proposal led to protests because it would destroy a lot of cultural relics. The Egyptian had no choice but ask the UN for help. Therefore, a international cooperation about how to protect the cultural relics began, which involved the time length about 20 years and a large amount of fund. Then, the problems was solved. 1.
