人教版高中語文必修3《杜甫詩三首》說課稿
我以以《登高》為例，引導(dǎo)學(xué)生進(jìn)行意象分析，感悟意境美。古人云“立象以盡意”“古詩之妙，專求意象”意象是詩人情感的載體，是詩歌的靈魂。引導(dǎo)學(xué)生張開聯(lián)想和想象的翅膀去感受，去體驗(yàn)是意象，詩歌鑒賞的關(guān)鍵。科林伍德說“真正藝術(shù)的作品，不是看見的，也不是聽到的，而是想象中的某種東西。”詩人通過想象創(chuàng)造出詩的形象，我們讀者通過想象豐富地再現(xiàn)詩人創(chuàng)造的形象。而感受體驗(yàn)則是以全部身心投入作品，心靈與心靈相溝通，感情與感情相交流，對(duì)詩人的想象活動(dòng)進(jìn)行再經(jīng)歷和再體驗(yàn)。因此，在引導(dǎo)意象解讀中，我先讓學(xué)生點(diǎn)擊這一個(gè)，就是通過抓修飾詞、依據(jù)感情基調(diào)、展開想象具體分析本詩中每個(gè)意象的情感意蘊(yùn)和審美意蘊(yùn)，使學(xué)生明白意象在每首詩中的獨(dú)特性。

4,教師重點(diǎn)點(diǎn)撥以下幾個(gè)問題⑴廊坊戰(zhàn)役:義和團(tuán)浴血奮戰(zhàn),對(duì)敵人毫不退縮, 其勝利，挫敗了西摩爾聯(lián)軍進(jìn)犯北京的計(jì)劃，沉重打擊了侵略者的氣焰，粉碎了所謂“西方軍隊(duì)無敵”的神話。這是對(duì)學(xué)生進(jìn)行愛國(guó)主義的重要素材之一，教師重點(diǎn)點(diǎn)撥突出其情感教育的重要作用。⑵讓學(xué)生（閱讀教材小字和材料，結(jié)合插圖，認(rèn)清八國(guó)聯(lián)軍對(duì)中國(guó)人民犯下的滔天罪行。）并讓學(xué)生分組探討自己的看法,一方面培養(yǎng)學(xué)生的語言表訴能力,另一方面通過學(xué)生的訴說激發(fā)學(xué)生的愛國(guó)情感,樹立落后就要挨打的觀念.⑶指導(dǎo)學(xué)生通過對(duì)條約主要內(nèi)容進(jìn)行了分析，并自然得出結(jié)論：清政府完全成為帝國(guó)主義統(tǒng)治中國(guó)的工具，中國(guó)完全陷入半殖民地半封建社會(huì)。讓學(xué)生逐步學(xué)會(huì)分析和歸納能力(4)進(jìn)行拓展訓(xùn)練出示中國(guó)近代史上列強(qiáng)的大規(guī)模的侵華戰(zhàn)爭(zhēng)和中國(guó)人民的反抗斗爭(zhēng)
人教版高中政治必修3建設(shè)學(xué)習(xí)型社會(huì)說課稿
解析：材料是講學(xué)習(xí)型社會(huì)所產(chǎn)生的影響，A項(xiàng)觀點(diǎn)錯(cuò)誤，在當(dāng)前和今后相當(dāng)長(zhǎng)的時(shí)間里，學(xué)校教育仍然是人們獲得知識(shí)的最重要的途徑。B項(xiàng)觀點(diǎn)錯(cuò)誤，終身學(xué)習(xí)只是成就人生目的的手段、途徑，而不是目的本身。D項(xiàng)說法錯(cuò)誤，當(dāng)前我國(guó)社會(huì)的中心工作是經(jīng)濟(jì)建設(shè)。二、問答題5.材料一：日本是公認(rèn)的漫畫大國(guó)，日本的動(dòng)漫產(chǎn)業(yè)產(chǎn)值每年230萬億日元，成為日本的第二大支柱產(chǎn)業(yè)。在日本，漫畫比電影、小說有時(shí)甚至比電視或音樂更受歡迎。日本漫畫的熱潮還席卷了世界：日本每年出口到美國(guó)的卡通片價(jià)值就達(dá)5 000億日元，是日本對(duì)美國(guó)鋼鐵出口金額的4倍；漫畫中的人物被迅速?gòu)?fù)制成電子游戲、卡通片及真人演出的節(jié)目。原來只是閑暇時(shí)候消遣的漫畫，正飛速滲透到人們的生活中。值得警惕的是，除了催人奮進(jìn)的精華之外，日本漫畫中也存在暴力、色情、扭曲歷史等諸多糟粕，對(duì)缺乏辨別能力的青少年產(chǎn)生了許多不良影響，更引發(fā)了一系列深刻的社會(huì)問題。

二、學(xué)生情況分析(說學(xué)法)1、學(xué)生學(xué)習(xí)基礎(chǔ)分析：學(xué)生通過對(duì)《生活與哲學(xué)》前面三個(gè)單元的學(xué)習(xí)，初步掌握了運(yùn)用唯物論、辯證法、認(rèn)識(shí)論的觀點(diǎn)去認(rèn)識(shí)問題、分析問題的能力；再通過對(duì)第十一課的學(xué)習(xí)，學(xué)生對(duì)馬克思主義的歷史觀有了初步的理解，初步樹立了正確的理想信念，這為本課教學(xué)目標(biāo)的落實(shí)奠定了知識(shí)基礎(chǔ)。 2、學(xué)生能力分析 ：高二學(xué)生擁有一定生活體驗(yàn)，具備一定的信息收集和篩選能力、閱讀能力、語言表達(dá)能力、對(duì)問題的一定的探究能力，同伴合作能力和具備初步邏輯思維能力。3、學(xué)生心理分析：在我國(guó)現(xiàn)階段，以為人民服務(wù)為核心的社會(huì)主義道德建設(shè)過程中涌現(xiàn)了大批的先進(jìn)人物和道德典范，但同時(shí)由于社會(huì)價(jià)值的多元化，個(gè)人主義、享樂主義、拜金主義等資本主義腐朽思想也同樣在影響著當(dāng)代的中學(xué)生。
人教版高中政治必修4生活處處有哲學(xué)說課稿
（二）組織學(xué)生探究知識(shí)并形成新的知識(shí)。我從學(xué)生的生活體驗(yàn)入手，運(yùn)用案例等形式創(chuàng)設(shè)情境呈現(xiàn)問題，使學(xué)生在自主探索、合作交流的過程中，發(fā)現(xiàn)問題、分析問題、解決問題，在問題的分析與解決中主動(dòng)構(gòu)建知識(shí)。主要通過幾幅漫畫讓學(xué)生思考其中的哲學(xué)道理，開始接觸哲學(xué)。漫畫一：種瓜得瓜，種豆得豆，種雞蛋得??漫畫二：甲：下雨好極啦！乙：下雨糟透了！漫畫三：——狂妄之徒，你竟然壞了祖上規(guī)矩！在引導(dǎo)學(xué)生思考、體驗(yàn)問題的過程中，可以使學(xué)生逐步學(xué)會(huì)分析、解決問題的方法。這樣做既有利于發(fā)展學(xué)生的理解、分析、概括、想象等創(chuàng)新思維能力，又有利于學(xué)生表達(dá)、動(dòng)手、協(xié)作等實(shí)踐能力的提高，促進(jìn)學(xué)生全面發(fā)展，力求實(shí)現(xiàn)教學(xué)過程與教學(xué)結(jié)果并重，知識(shí)與能力并重的目標(biāo)。

人教版高中英語必修4A taste of English Humor說課稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
人教版高中英語必修4Women of achievement說課稿4篇
Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.

因此，本套教材中刪去了“整除”的數(shù)學(xué)化定義，而是借助整除的模式na＝b直接引出因數(shù)和倍數(shù)的概念。在本冊(cè)教材中，由于允許學(xué)生采用多樣的方法求最大公因數(shù)和最小公倍數(shù)，分解質(zhì)因數(shù)也失去了其不可或缺的作用，同時(shí)，也是為了減少這一單元的理論概念，教材不再把它作為正式教學(xué)內(nèi)容，而是作為一個(gè)補(bǔ)充知識(shí)，安排在“你知道嗎？”中進(jìn)行介紹。由于這部分內(nèi)容較為抽象，很難結(jié)合生活實(shí)例或具體情境來進(jìn)行教學(xué)，學(xué)生理解起來有一定的難度。在過去的教學(xué)中，一些教師往往忽視概念的本質(zhì)，而是讓學(xué)生死記硬背相關(guān)概念或結(jié)論，學(xué)生無法理清各概念間的前后承接關(guān)系，達(dá)不到融會(huì)貫通的程度。再加上有些教師在考核時(shí)使用一些偏題、難題，導(dǎo)致學(xué)生在學(xué)習(xí)這部分知識(shí)時(shí)覺得枯燥乏味，體會(huì)不到初等數(shù)論的抽象性、嚴(yán)密性和邏輯性，感受不到數(shù)學(xué)的魅力。所以在教學(xué)中應(yīng)注意以下兩點(diǎn): （1）加強(qiáng)對(duì)概念間相互關(guān)系的梳理，引導(dǎo)學(xué)生從本質(zhì)上理解概念，避免死記硬背。（2）由于本單元知識(shí)特有的抽象性，教學(xué)時(shí)要注意培養(yǎng)學(xué)生的抽象思維能力。

教師問：Can you spell these words? 如有學(xué)生能夠拼出單詞，教師要給與表揚(yáng)并說：那讓我們來看一看他拼的對(duì)不對(duì)，然后出示單詞卡。如沒有學(xué)生拼出單詞，教師說：我們學(xué)習(xí)單詞不僅要會(huì)說還要會(huì)寫，今天我們就來學(xué)習(xí)幾個(gè)單詞的拼寫，看誰學(xué)得快。然后出示單詞卡。 讓學(xué)生看單詞卡拼讀單詞。 教師讓學(xué)生看單詞回答：How many letters in this word?學(xué)生回答后，讓他們背著拼出單詞。 教師讓學(xué)生在四線三格中默寫字母b, o, k, r, l, e, p, n, c, I, a,教師教學(xué)生在四線三格中書寫單詞。告訴學(xué)生首先要把每個(gè)字母書寫正確，然后按照單詞的拼寫把字母寫在一起，注意單詞的每個(gè)字母間要有一點(diǎn)距離。教師在教寫ruler和pencil-case時(shí)， 注意小寫u和s還沒有學(xué)習(xí)書寫，讓學(xué)生照著板書寫就可以了。 讓學(xué)生照板書抄字頭，然后每個(gè)單詞寫一行。 （三）趣味操練（Practice）
