人教版新課標高中物理必修1摩擦力說課稿2篇
本節(jié)課是人教社物理必修1第三章第三節(jié)的內容，編排在彈力之后。該節(jié)知識既是力學的基礎，也是組成整個高中物理知識的一塊“基石”，所以這節(jié)內容的教學如何引領學生自主積極地探究摩擦力產生的條件和影響因素，體驗摩擦力特點規(guī)律的發(fā)生過程是本節(jié)課的重點，應高度重視本節(jié)教學過程；由于摩擦力問題的復雜性，且在具體問題中又表現(xiàn)出“動中有靜，靜中有動”，尤其靜摩擦在許多情形下似乎又是“若有若無，方向不定”，因此，對于初學者也是有一定難度的。也正是由于教材內容的上述特點，本節(jié)課又易于激起學生的求知欲，易于培養(yǎng)學生的辯證觀點，易于錘煉學生的物理素質。要充分用好該節(jié)教材內容，深入挖掘知識間的有機聯(lián)系，對學生開展針對性的思維訓練，進而提高學生應用物理知識解決實際問題的能力和創(chuàng)新思維能力。高中物理《課標》對該知識點的要求是，“通過實驗認識滑動摩擦、靜摩擦的規(guī)律，能用動摩擦因數(shù)計算摩擦力”。其中，對靜摩擦力規(guī)律的認識應該包括最大靜摩擦力。

（一）、復習提問1、請說出功的計算公式及功的單位2、我們用哪個物理量表示物體運動的快慢？（二）、創(chuàng)設情景，引入新課1、播放多媒體素材，用起重機和一個工人搬運幾百塊磚比較哪一種方法好？圖中的情景說明了什么問題?（教師通過所設計的情景，將學生引入怎樣比較做功快慢，讓學生發(fā)表自己的看法，初步知道物體做功是有快慢之分的。）（三）、進行新課1、比較做功快慢的方法播放多媒體素材并提出問題：怎樣比較兩個人誰做功快誰做功慢？教師啟發(fā)：以前學習過要比較兩物體運動的快慢，可以先確定路程再比較時間，也可以先確定時間再比較路程。在路程和時間都不同時，通過計算速度比較兩物體運動的快慢。同理，要比較物體做功的快慢可采用什么方法？

探究一：高中階段功的含義是什么？投影：初中九年級《物理》105頁學生思考：①圖中物體的勢能、動能分別如何變化？②物體能量的變化和做功是否存在關系？學生:分組討論，得出結論：如果物體的能量發(fā)生變化時，說明有力對物體做了功。教師:進行點評和小結(設計意圖：對初中知識深化理論認識，并為以后功能關系的教學作準備)探究二：力對物體做功的兩個要素是什么？情景再現(xiàn)：找體重相對懸殊的兩位同學，①A同學試圖抱起B(yǎng)同學，但沒成功。②B同學抱起A同學在教室內勻速走動。學生思考：在①中，A是否對B做功？在②中，B是否對A做功？學生:分析得出做功的兩要素：物體受到力的作用，并且在力的方向上發(fā)生位移.教師:讓學生分別例舉生活中力對物體做功和不做功的例子，（設計意圖：讓學生親身參與課堂實驗，烘托課堂氣氛，相互協(xié)作增進同學情誼）探究三：如果物體的位移不再力的方向上，那么力是否還對物體做功？

通過這個示例呢，我們可以得到解決向心力問題的一般的步驟，確定對象，找出軌跡，找出圓心，然后進行受力分析，讓同學們參考這樣的步驟，逐步的解決圓周運動的問題，對于變速圓周運動，我通過鏈球運動進行引入，這里是一個鏈球運動的視頻，在同學們觀看視頻之前，我給同學們提出問題，鏈球收到繩子的拉力，做的是勻速圓周運動嗎？ 然后再課堂上我們再做一個小實驗， 我們可以通過改變拉線的方式來調節(jié)小球的速度大小嗎？ 那么對小球，做加速圓周運動，進行受力分析，我們可以看到，小球做加速運動時，他所受到的力，并不是嚴格通過軌跡的圓心，在進行分析的時候，特別強調，小桶所受力的切線方向分力，和法線方向分力，切線方向分力，改變小球運動速度大小，法線方向分力，改變了小球運動的方向，法線方向的分力，在這里就是向心力，產生了向心加速度，通過這樣一個例子進行分析，同學們是比較容易理解的，
新人教版高中英語必修3Unit 5 The Value of Money-Reading and Thinking教學設計一
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

人教版高中政治必修4時代的精神的精華說課稿
（二）能力目標培養(yǎng)學生運用哲學理論觀察、分析、處理社會問題的能力，增強學生的時代感。（三）情感、態(tài)度與價值觀目標培養(yǎng)學生與時俱進的思想品質，讓學生關注時代、關注現(xiàn)實、關注生活，逐步樹立科學的世界觀、人生觀、價值觀。三、說教學重難點：時代精神的總結和升華是本框的難點，雖然學生在文化生活中學習了文化與經濟政治的關系，但要讓學生得出哲學是時代精神的總結和升華，還要聯(lián)系前面關于哲學的基礎知識進行總結歸納，因此可能會難以把握，另外關于什么樣的哲學是真正的哲學的理解會稍有難度。社會變革的先導是本框的重點，一方面哲學源于時代，另一方面強調哲學反過來對時代又有重要的反作用，突出這一點能夠更好地激發(fā)學生學習哲學的熱情和信心，對于后面知識的學習是極為有益的，因此社會變革的先導這一目作重點處理。
