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.

人教版高中地理必修2煤城焦作出路何在說課稿
分析過焦作市的地理概況和產(chǎn)業(yè)優(yōu)勢(shì)后，就需要針對(duì)由于資源枯竭所帶來的問題提出合理化的建議。既然是談經(jīng)濟(jì)轉(zhuǎn)型，就應(yīng)該將話題的范圍明確在這一領(lǐng)域內(nèi)。通過材料3的相關(guān)內(nèi)容，我們了解到焦作市需要在產(chǎn)業(yè)結(jié)構(gòu)調(diào)整、培育新的優(yōu)勢(shì)產(chǎn)業(yè)、增強(qiáng)綜合競爭力等三個(gè)整改方針上下功夫。因而引導(dǎo)學(xué)生針對(duì)優(yōu)勢(shì)與不足提出建議，以三個(gè)整改方針為基準(zhǔn)，衡量建議的可行性是鍛煉學(xué)生解決此類問題的有效途徑。在此我將教會(huì)學(xué)生的是解決問題方法而非案例的內(nèi)容，正所謂“授之以魚，不如授之以漁”。接下來針對(duì)學(xué)生的建議和教材資料分析所羅列的10點(diǎn)整改思路，由學(xué)生自由發(fā)言提出看法，通過教師的指導(dǎo)和學(xué)生的討論，進(jìn)而確定經(jīng)濟(jì)轉(zhuǎn)型建議的具體方案。最后注意將建議與產(chǎn)業(yè)優(yōu)勢(shì)相對(duì)照，看建議是否都是圍繞著產(chǎn)業(yè)優(yōu)勢(shì)而提出的，這樣做會(huì)加深學(xué)生的印象，通過建議和優(yōu)勢(shì)的對(duì)應(yīng)關(guān)系，將不難找出此類問題的解題思路。

基于以上分析，為使本堂課圍繞重點(diǎn)、突破難點(diǎn)，同時(shí)讓學(xué)生在課堂教學(xué)中能力得到提高，我設(shè)計(jì)如下教學(xué)過程。（一）創(chuàng)設(shè)情景認(rèn)識(shí)形變由同學(xué)們已有的形變知識(shí)入手，引入新課。教師演示：①彈簧的壓縮形變；②彈簧的拉伸形變③視頻播放：竹竿形變、鋼絲的扭轉(zhuǎn)形變。得出形變的概念及各類形變。[設(shè)計(jì)意圖：我從生活情景中引入新課，是為了激發(fā)學(xué)生的好奇心，為學(xué)生學(xué)習(xí)重點(diǎn)和難點(diǎn)內(nèi)容作鋪墊。]設(shè)問：摩天大樓在風(fēng)的吹拂下會(huì)不會(huì)擺動(dòng)，發(fā)生形變嗎？演示微小形變放大實(shí)驗(yàn)：由于這種形變不容易觀察，會(huì)使學(xué)生產(chǎn)生疑問：到底有沒有發(fā)生形變？解決的辦法是微小形變的演示實(shí)驗(yàn)。為什么光點(diǎn)會(huì)往下移？讓學(xué)生帶著問題思考后得出結(jié)論：是由于桌面發(fā)生了形變，但是形變不明顯。為后面解決壓力和支持力都是彈力做好鋪墊。[設(shè)計(jì)意圖：使學(xué)生知道“放大”是一種科學(xué)探究的方法。]

本節(jié)課是人教社物理必修1第三章第三節(jié)的內(nèi)容，編排在彈力之后。該節(jié)知識(shí)既是力學(xué)的基礎(chǔ)，也是組成整個(gè)高中物理知識(shí)的一塊“基石”，所以這節(jié)內(nèi)容的教學(xué)如何引領(lǐng)學(xué)生自主積極地探究摩擦力產(chǎn)生的條件和影響因素，體驗(yàn)?zāi)Σ亮μ攸c(diǎn)規(guī)律的發(fā)生過程是本節(jié)課的重點(diǎn)，應(yīng)高度重視本節(jié)教學(xué)過程；由于摩擦力問題的復(fù)雜性，且在具體問題中又表現(xiàn)出“動(dòng)中有靜，靜中有動(dòng)”，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(duì)于初學(xué)者也是有一定難度的。也正是由于教材內(nèi)容的上述特點(diǎn)，本節(jié)課又易于激起學(xué)生的求知欲，易于培養(yǎng)學(xué)生的辯證觀點(diǎn)，易于錘煉學(xué)生的物理素質(zhì)。要充分用好該節(jié)教材內(nèi)容，深入挖掘知識(shí)間的有機(jī)聯(lián)系，對(duì)學(xué)生開展針對(duì)性的思維訓(xùn)練，進(jìn)而提高學(xué)生應(yīng)用物理知識(shí)解決實(shí)際問題的能力和創(chuàng)新思維能力。高中物理《課標(biāo)》對(duì)該知識(shí)點(diǎn)的要求是，“通過實(shí)驗(yàn)認(rèn)識(shí)滑動(dòng)摩擦、靜摩擦的規(guī)律，能用動(dòng)摩擦因數(shù)計(jì)算摩擦力”。其中，對(duì)靜摩擦力規(guī)律的認(rèn)識(shí)應(yīng)該包括最大靜摩擦力。

“深入探究，把握主旨”這一步則是解決教學(xué)的重點(diǎn)難點(diǎn)，這里涉及到課文的深層意蘊(yùn)，學(xué)生理解有難度，教師在通過問題引領(lǐng)學(xué)生探討的基礎(chǔ)上，還要適時(shí)啟發(fā)、點(diǎn)撥，因?yàn)榻虒W(xué)時(shí)間有限，讓學(xué)生漫無邊際的討論，可能難以完成預(yù)定的教學(xué)任務(wù)，會(huì)使教學(xué)過程不完整。至于本文的寫作特點(diǎn)的教學(xué)視時(shí)間而定，有時(shí)間可以讓學(xué)生說一說，沒有時(shí)間用小黑板出示一下，讓學(xué)生了解就行，如果時(shí)間不夠，甚至可以不講。第三階段是“延伸練習(xí)，鞏固提高”。
人教版高中語文必修2《蘭亭集序》說課稿3篇
（二）分析課文，理清思路第1、2段為第一部分，主要是敘事、寫景，先敘述集會(huì)的時(shí)間、地點(diǎn)，然后渲染出蘭亭優(yōu)美的自然環(huán)境。在這里足以“游目騁懷”“極視聽之娛”，可以自由地觀察、思考，滿足人們目視耳聞的需求。這里正是與會(huì)“暢敘幽情”、盡興盡歡的絕好處所。這些描寫都富有詩情畫意，作者的情感是輕松愉快的。第3、4段為第二部分，主要是抒情、議論，作者由美景妙時(shí)引發(fā)出樂與憂、生與死的感慨。他認(rèn)為人生的快樂是有極限的，待快樂得到滿足時(shí)，就會(huì)感覺興味索然。往事轉(zhuǎn)眼間便成為歷史，人到了生命的盡頭就會(huì)死亡。作者由“一死生為虛誕，齊彭殤為妄作”的認(rèn)識(shí)，產(chǎn)生了一種珍惜時(shí)間、眷戀生活、熱愛文明的思考。雖然文中的壽夭、生死不能自由決定，從而有些傷感，但作者仍然認(rèn)識(shí)到盛衰、生死是必然的。人生無常，時(shí)不我待，故著文留傳后世，以承襲前人，啟示來者。
