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

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.

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.

After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.

人教版高中語文必修1《人性光輝：寫人要凸顯個性》說課稿2篇
人教版新課標教材必修一的“表達交流”部分，有一個專題是“人性的光輝——寫人要凸顯個性”。其中的“寫法借鑒”部分列舉了兩則人物描寫實例，并歸納出人物描寫的幾個要點。其訓練的思路和方法是很明顯的，但所列舉的人物描寫的實例卻不夠典型。而必修一第三單元正好是學習寫人記事散文，其中的兩篇自讀課文《記梁任公先生的一次演講》《金岳霖先生》又是寫人記事非常典型的文章，故而我嘗試將這兩篇文章作為實例和。寫人要凸顯個性。寫作指導結合起來教學。這樣設計還有一個目的，那就是解決課程改革中教學內(nèi)容多而課時緊張的矛盾，提高課堂教學效率。師：今天，我們一起來學習“寫人要凸顯個性”。這兩堂課分四個步驟來完成：一、先學習教材中關于寫人方法的介紹，約15分鐘；二、快速閱讀第三單元的《記梁任公先生的一次演講》和《金岳霖先生》兩篇文章，具體感受其寫人的方法，約30分鐘；
人教版高中語文必修1《奧斯維辛沒有什么新聞》說課稿2篇
第11段很短，只點出了這是“在婦女身上搞不育試驗的地方”，但在最末又加了一句“否則他會羞紅了臉的”，這是為什么？那肯定是一個極為骯臟，極為殘酷的地方。據(jù)資料記載：當時的希特勒制定一項令所有被征服或占領國家的民族充當奴隸并且逐漸消亡的隱密性種族滅絕計劃——高效率、大規(guī)模的強制絕育。為此，數(shù)以百計的納粹醫(yī)生、教授、專家甚至護士，在行政管理專家的通力合作下，相繼提出了幾十種絕育方法，十余種實施方案，并且在奧斯維辛、拉芬斯布呂克、布亨瓦爾特、達豪等十多個大型集中營內(nèi)對數(shù)以萬計的猶太、吉普賽囚犯、因從事抵抗運動而被捕的政治犯和男女戰(zhàn)俘進行了殘酷的手術試驗，造成他們大量死亡或者終身殘疾、終身不育。這樣殘酷的毫無人性的手段，任誰也不愿看到。
人教版高中語文必修1《別了，“不列顛尼亞”》說課稿2篇
一、說教材《別了，不列顛尼亞》是編排在人教版《普通高中課程標準實驗教科書語文1（必修）》第四單元的課文，是精讀課文《短新聞兩篇》中的一篇，另一篇是《奧斯維辛沒有什么新聞》。這一單元的學習內(nèi)容是新聞和報告文學，還有兩篇作品分別是中國報告文學三大里程碑之一的《包身工》和記錄中國航天事業(yè)輝煌發(fā)展的《飛向太空的航程》。在當今信息大爆炸的時代，如何快速獲得信息，如何在新聞中解讀事件的真相，感悟生活的內(nèi)涵成為語文教學的又一重大任務。因此這一單元的編入便更多地具有了時代意義，體現(xiàn)了語文學科與日常生活的密切關系。不僅如此，新聞特寫和報告文學的選入，拓寬了學生對新聞類文章的了解，體現(xiàn)語文學科的工具性作用。在選文的過程中，新教材同時注重語文學科的人文性，四篇作品不僅傳遞著新鮮、真實的信息，同時更張顯人文性的厚度，他們以飽滿的情感，縱橫的歷史經(jīng)驗。

現(xiàn)代詩歌賞讀方法四：美讀（飽含謳歌與贊美情感再一次有感情地配樂朗讀全文，對比前面的朗讀，在讀中加深情感的領悟。）（五）延伸拓展引進生活的源頭活水,用情感來撞開學生的心扉。引導學生找到文章與現(xiàn)實的聯(lián)系點，抓住這一聯(lián)系點，讓語文回歸生活。我設計了“本詩哪些語段讓你聯(lián)想到自己的母親？講講你和母親的故事。”這個問題是把對大堰河的感情升華為對母親的感情的過程。這樣將語文學習的外延與生活的外延相等，把課文與生活有機地結合在一起。要求學生講述條理清楚，語言生動。教師可以播放背景音樂，調(diào)動學生情感。這樣，不僅鍛煉了學生的口語表達能力，培養(yǎng)了學生感恩美德，同時也深化了本文的教學難點?，F(xiàn)代詩歌賞讀方法五：比讀（投影出示孟郊《游子吟》比較兩詩的異同，并有感情地朗誦。）（六）布置作業(yè)。把“你與母親的故事”整理成一篇文章。
人教版高中語文必修1《記梁任公先生的一次演講》說課稿2篇
6、思考：作者心目中的梁啟超是什么形象呢？明確：梁任公是位有學問，有文采，有熱心腸的學者。由學生找出文中體現(xiàn)梁啟超學問、文采的句子。教師展示幻燈。補充介紹：文采不僅體現(xiàn)在書面，也能從流暢的口語表達中反映?！扼眢笠范潭淌痔N涵了什么故事，竟讓梁啟超描述得生動感人以至作者多年后還印象深刻呢？《箜篌引》出自《漢樂府詩》，記敘了一個悲慘壯烈的故事：朝鮮水兵在水邊撐船巡邏時，見一個白發(fā)狂夫提壺渡江，被水沖走。他的妻子勸阻不及，悲痛欲絕，取出箜篌對著江水反復吟唱。一曲終了，她也投河隨夫而去。朝鮮水兵回家向自己的妻子麗玉講述了這個故事，麗玉援引故事中的悲情，創(chuàng)作了這首歌曲，聽過的人無不動容。7、朗讀訓練了解《箜篌引》的故事后，請各小組選派代表朗讀，由學生點評，體會梁啟超演講技巧的高超。8、文中說梁任公是個熱心腸的人，你同意嗎？通過結尾段的“熱心腸”轉入對其人格的分析。

問：為什么會出現(xiàn)這樣的情況，男女生之間的拉力存在著怎樣的大小關系？進一步求證這兩個力的大小關系經(jīng)過共同討論，得方案：把兩個彈簧秤勾在一起，重現(xiàn)拔河比賽，分三種情況進行。（通過攝像頭把彈簧秤的讀數(shù)放大）兩彈簧稱勾在一起拉，處于靜止不動時（即拔河比賽，雙方處于僵持狀態(tài)）兩彈簧稱勾在一起拉，并向一方運動（即比賽繩子被拉向一方時的狀態(tài)）3、兩彈簧稱勾在一起拉，一方方向慢慢改變（兩力方向始終在一條直線上）實驗結論：兩彈簧稱的讀數(shù)的變化總是相同的，大小相等，方向相反。得到牛頓第三定律：追問：既然兩個力大小相等，那么拔河比賽為什么還存在勝負之分？講清作用力與反作用力作用的受力物體不同，并和學生討論如何做才會獲勝?；貞n前問題：“以卵擊石”為什么雞蛋碎？
人教版新課標高中物理必修1牛頓第二定律說課稿2篇
進一步引導學生思考利用數(shù)學知識可寫成等式F=kma學生很自然就會思考比列系數(shù)K應該是多少？通過教師引導學生舉例各國長度單位不同（如英國：英里、碼、英尺、英寸；中國：市里、市丈、市尺、市寸、市分 ）導致交流不便。為了適應各國交流需要國際計量局規(guī)定了一套統(tǒng)一的單位，稱為國際單位制 。取不同的單位制K是不同的，為了簡潔方便，在選取了質(zhì)量和加速度的國際單位（Kg, m/s2)時規(guī)定K=1。那么就有；F=ma為了紀念牛頓，就把能使1kg物體獲得1m/s2加速度的力稱做一牛頓，用符號N表示問題：實際物體受力往往不止一個，多個力情況應該怎么辦呢？平行四邊形法則進一步引導學生得出牛頓第二定律更一般的表達式: F合=ma思考.討論我們用力提一個很重的箱子，卻提不動它。這個力產(chǎn)生了加速度嗎？要是產(chǎn)生了，箱子的運動狀態(tài)卻并沒有改變。為什么？
人教版新課標高中物理必修1時間和位移說課稿2篇
研究一種物理現(xiàn)象，總是要先從現(xiàn)象的描述入手。機械運動作為自然界最簡單和最基本的運動形態(tài)，它所描述的是物體空間位置隨時間變化的情況。因此，本節(jié)學習描述質(zhì)點做機械運動需要時刻、時間間隔和位移等概念。相當一部分高一學生在具體過程中難以區(qū)別時刻和時間間隔。另外，由于思維的定式，在第一次接觸既要考慮大小又要考慮方向的問題時，會因不適應造成學習困難。所以，區(qū)別“路程與位移”“時刻和時間間隔”是教學的重難點所在。學習這些內(nèi)容的過程與方法對學習速度和加速度可以起到奠定基礎的作用。教學的對象是高一的學生，這一時期的學生處在好奇善問、創(chuàng)新意識強烈的青少年期。對于生活中出現(xiàn)的各種現(xiàn)象具有濃厚的興趣。但他們的思維還停留在簡單的代數(shù)運算階段，對于矢量和矢量運算的理性認識幾乎沒有。且對生活中出現(xiàn)的時間、時刻、時間間隔等不能做出很好的區(qū)分，對時常提及的路程、距離等形成了模糊的前概念。
人教版新課標高中物理必修1自由落體運動說課稿2篇
學生回答的方法多樣，讓各小組根據(jù)自己討論出來的方法對自己實驗出來的紙帶進行數(shù)據(jù)處理，并求出加速度，并且將多條紙帶都進行處理，同時提醒學生對紙帶的選擇。接著，我會用多媒體展示重物下落實驗打出來的紙帶，用表格列出一段紙帶上各點的瞬時速度，準確畫出v-t圖像，求出加速度，將結果給予學生的結果作對比，確定出正確結論。最后讓學生分析總結：自由落體運動是初速度為零的勻加速直線運動，而且，多條紙帶算出來的加速度的數(shù)值都接近相等，即加速度在實驗誤差允許范圍內(nèi)是相等的。引出重力加速度，介紹概念、方向及大小。（強調(diào)“同一地點”，讓學生閱讀教材中一些地點的重力加速度，可以了解重力加速度的大小與緯度有關，緯度越大加速度越大）。學習了重力加速度后讓學生根據(jù)之前學習的勻變速直線運動公式推導出自由落體的運動規(guī)律。設計意圖：讓學生在學習過程中的主體地位和自主觀能動性得到充分發(fā)揮，取長補短，培養(yǎng)了學生的實驗操作能力，又使學生對自由落體運動的性質(zhì)有深刻的印象，從而解決了本節(jié)課第二個難點。
