人教版新課標高中物理必修1探究小車速度隨時間變化的規(guī)律說課稿2篇
（三）合作交流能力提升教師：剛才我們通過實驗了解了小車的速度是怎樣隨時間變化的，但實驗中有一定的誤差，請同學們討論并說出可能存在哪些誤差，造成誤差的原因是什么？（每個實驗小組的同學之間進行熱烈的討論）學生：測量出現(xiàn)誤差。因為點間距離太小，測量長度時容易產(chǎn)生誤差。教師：如何減小這個誤差呢？學生：如果測量較長的距離，誤差應該小一些。教師：應該采取什么辦法？學生：應該取幾個點之間的距離作為一個測量長度。教師：好，這就是常用的取“計數(shù)點”的方法。我們應該在紙帶上每隔幾個計時點取作一個計數(shù)點，進行編號。分別標為：0、1、2、3……，測各計數(shù)點到“0”的距離。以減小測量誤差。教師：還有補充嗎？學生1：我在坐標系中描點畫的圖象只集中在坐標原定附近，兩條圖象沒有明顯的分開。學生2：描出的幾個點不嚴格的分布在一條直線上，還能畫直線嗎？
人教版新課標高中物理必修1速度變化快慢的描述─加速度說課稿2篇
本來比較速度變化的快慢也有兩種方法：一種是比較相同時間內(nèi)速度變化量的大??；另一種是比較發(fā)生相同的速度變化所需要的時間長短。但教材是將比較質(zhì)點位置移動快慢的思想直接遷移過來，通過實例分析，使學生明白不同運動物體的速度變化快慢不同，表現(xiàn)在速度的變化與發(fā)生這個變化所用時間的比值不同，從而引入加速度的定義方法a=△v/△t。加速度表示速度的變化快慢，包括速度增加的快慢和減小的快慢，不能誤認為只要有加速度的運動速度就一定是增加的。廣義地講，加速度不僅可以描述速度大小的變化快慢，而且也可以描述速度方向變化的快慢，本節(jié)教材只限定在直線運動的情景中討論。加速度的矢量性是一個難點，教材是以與速度方向相同或是相反來表述加速度的矢量性的。如果以初速度方向為正方向，那么加速度就有正負之分，加速度的正負表示加速度的方向，不表示加速度的大小。
人教版高中語文必修2《我有一個夢想》教案2篇
全班齊讀第五段內(nèi)容。請一位同學分析，接著讓這位同學按他分析的讀一遍。3、4兩自然段的平緩之后，第5段作者的情感再次抬升。為了滿足這種情感的張揚，作一口氣連用了四個排比句式“現(xiàn)在是……時候”，一方面這是情感發(fā)泄的需要，另一方面這種排山倒海的語勢也加強了內(nèi)容的表達，極強地突出了現(xiàn)實為自由、平等而戰(zhàn)的重要性。四、學會演講我們剛才細讀了課文，但讀和講是有區(qū)別的。所謂演講，是一門語言藝術，它的主要形式是“講”，即運用有聲語言并追求言辭的表現(xiàn)力和聲音的感染力；同時還要輔之以“演”，即運用面部表情、手勢動作、身體姿態(tài)乃至一切可以理解的態(tài)勢語言，使講話“藝術化”起來，從而產(chǎn)生一種非凡的藝術魅力。那么，接下來就假設一下假如你是馬丁·路德·金，你會怎樣去講這篇演講辭。
人教版高中歷史必修1祖國統(tǒng)一大業(yè)教案2篇
教材分析改革開放后我國的綜合國力不斷增強，人民對祖國統(tǒng)一的愿望越來越迫切。本節(jié)課以“一國兩制”構想的提出，香港、澳門的回歸和海峽兩岸關系的發(fā)展為中心，說明實現(xiàn)祖國統(tǒng)一，完成中華民族復興是歷史發(fā)展的必然。第一目“‘一國兩制’構想的提出”主要講述了“一國兩制”的含義及歷史意義。第二目“香港、澳門的回歸”著重講述了香港回歸、澳門回歸的經(jīng)過及歷史意義，這是“一國兩制”成功的實踐。第三目“海峽兩岸關系的發(fā)展”講述了大陸注重發(fā)展與臺灣的關系，促進海峽兩岸的經(jīng)濟文化交流與合作，打破了幾十年來海峽兩岸的隔絕狀態(tài)，促進了祖國統(tǒng)一的進程。此外，教材還通過“資料回放”“歷史縱橫”“學思之窗”等欄目，為學生學習提供了一些詳細的史料。在教學中要分析圖表資料，引導學生理解完成祖國統(tǒng)一大業(yè)，實現(xiàn)中華民族的復興，是任何人也阻擋不了的歷史潮流。

人教版高中歷史必修2羅斯福新政教案
【教學參考】對“新政”作用的評價史學界對“新政”作用的評價是仁者見仁、智者見智，但基本上有三種觀點，即“功大于過論”、“過大于功論”和“功過參半論”。持“功大于過論”者認為“新政”在美國歷史上基本上是一種進步現(xiàn)象，首先，“新政”挽救了危機，使美國人民擺脫了危機的困苦局面；其次，在缺少足夠的宏觀經(jīng)濟政策知識的時代，羅斯福所做的努力確實是開創(chuàng)性的；再次，羅斯福“新政”開啟了美國以后歷屆政府實施國家干預政策的大門，成為緩解自由主義經(jīng)濟制度之弊病的一劑良方，并在實質(zhì)上加強了美國聯(lián)邦政府的權威；最后，在30年代資本主義世界經(jīng)濟危機的背景下，同日本、德國為轉嫁危機而發(fā)動戰(zhàn)爭的策略相比，“新政”無疑代表了一種進步、民主的解救危機方式。持“過大于功論”者認為“新政”未能使美國走出蕭條、步入繁榮。
