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.

Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. 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.

人教版新課標(biāo)高中物理必修1用牛頓運動定律解決問題（一）說課稿
六、教學(xué)程序設(shè)計（“一三五”模式）為了完成這節(jié)課的教學(xué)目標(biāo)，我是這樣安排的：第一環(huán)節(jié)： （約10分鐘）根據(jù)對自主探究案的批閱情況，解決學(xué)生的遺留問題具體實施：投影學(xué)生的自主探究案，讓學(xué)生交流討論，教師點評。第二環(huán)節(jié)： （ 約30分鐘）新課學(xué)習(xí)：在“課堂互動案”的導(dǎo)學(xué)提綱引領(lǐng)下，完成這節(jié)課的三維教學(xué)目標(biāo)。具體實施：多媒體輔助教學(xué)、交流討論。第三環(huán)節(jié)： （約5分鐘）課堂小結(jié)和布置作業(yè)：為了體現(xiàn)課程改革的新理念——學(xué)生是學(xué)習(xí)的主人，我改變傳統(tǒng)的教師總結(jié)為學(xué)生總結(jié)的模式，既強化了學(xué)生所學(xué)的知識，又培養(yǎng)了學(xué)生的歸納和概括能力。作業(yè)分為兩部分：（1）書面作業(yè)p85，1、2、3、4。（2）完成“應(yīng)用提升案”。七、板書設(shè)計由于多媒體在物理教學(xué)中僅是一種輔助手段，不能完全取代黑板，因此一節(jié)課的主要內(nèi)容和學(xué)生的必要參與還需要借助黑板來幫助。我在這節(jié)課的板書設(shè)計中突出了主要內(nèi)容，簡潔明了。
人教版高中生物必修2基因突變和基因重組說課稿
1、教材內(nèi)容本節(jié)是人教版普通高中標(biāo)準(zhǔn)實驗教科書生物必修2《遺傳與進化》的第五章《基因突變及其他變異》的第一節(jié)內(nèi)容。本節(jié)介紹了可遺傳變異的兩種類型：基因突變和基因重組，其中基因突變從實例對鐮刀型細(xì)胞貧血癥的分析入手，引入基因突變的概念，然后詳細(xì)闡述基因突變的原因和特點、意義。在闡述自然狀態(tài)下基因突變的頻率很低時，教材用實例說明在一個足夠大的群體中，即使基因突變頻率很低，突變個體仍然會占有一定的數(shù)量。這個實例體現(xiàn)了生物在進化過程中“變”與“不變”的平衡，有助于學(xué)生理解基因突變在生物進化中所占有的重要地位。在基因重組部分，教材設(shè)置了“思考與討論“的欄目，旨在讓學(xué)生利用數(shù)學(xué)方法，通過計算，體會基因重組機制提供的極其多樣的基因組合方式，從而幫助學(xué)生理解基因重組是生物多樣性形成的主要原因。正文中則簡要闡述了基因重組的概念、類型和意義。本節(jié)內(nèi)容引導(dǎo)學(xué)生從分子水平上理解遺傳物質(zhì)如何引起生物變異的。
人教版新課標(biāo)高中物理必修1質(zhì)點參考系和坐標(biāo)系說課稿2篇
一、說教材《質(zhì)點 參考系和坐標(biāo)系》是人教版普通高中物理必修一第一章第一課的內(nèi)容。本節(jié)課主要介紹了質(zhì)點、參考系、坐標(biāo)系的基本概念。通過本節(jié)課的學(xué)習(xí)為進一步學(xué)習(xí)后續(xù)課程起到了鋪墊的作用。根據(jù)上述教材的結(jié)構(gòu)和內(nèi)容分析，又考慮到高一年級學(xué)生的認(rèn)知結(jié)構(gòu)及其心理特征，我制定了以下三維教學(xué)目標(biāo)：1、知識與技能：知道質(zhì)點的概念及條件；知道參考系的概念及作用；掌握坐標(biāo)系的簡單應(yīng)用。2、過程與方法：促進學(xué)生自主學(xué)習(xí)，讓學(xué)生積極參與、樂于探究、勇于實驗、勤于思考，培養(yǎng)學(xué)生的科學(xué)探究能力。3、情感態(tài)度與價值觀：通過質(zhì)點 參考系和坐標(biāo)系的學(xué)習(xí)，使學(xué)生了解生活與物理的關(guān)系，讓學(xué)生學(xué)會用科學(xué)的思維去看待事物。根據(jù)普通高中物理課程標(biāo)準(zhǔn)，并在吃透教材的基礎(chǔ)上，我確定了以下教學(xué)重點和難點：教學(xué)重點：質(zhì)點概念的建立。只有掌握了這一點才能更加準(zhǔn)確的理解和掌握后續(xù)教材的相關(guān)內(nèi)容。
人教版新課標(biāo)高中物理必修2探究功與速度變化的關(guān)系教案2篇
說明：“倍增法”是一種重要的物理方法，歷史上庫侖在研究電荷間的相互作用力時曾用過此法，但學(xué)生在此前的物理學(xué)習(xí)中可能未曾遇到類似例子，因此引導(dǎo)學(xué)生通過交流，領(lǐng)會“倍增法”的妙處，這是本節(jié)課的一個要點．可用體育鍛煉中的“拉力器”來類比。（2）該方案消除摩擦力影響的方法：所用的消除方法與實驗方案2一樣。也可使用氣墊導(dǎo)軌代替木板，以更好地消除摩擦影響。（3）小車速度的確定方法：①確定打出來的點大致呈現(xiàn)什么規(guī)律：先密后疏（變加速），再均勻分布（勻速）；②應(yīng)研究小車在哪個時刻的速度：在橡皮筋剛恢復(fù)原長時小車的瞬時速度，即紙帶上的點剛開始呈現(xiàn)均勻分布時的速度；③應(yīng)如何取紙帶上的點距以確定速度：由于實驗器材和每次操作的分散性，尤其是橡皮筋不可能長度、粗細(xì)完全一致，使得每次改變橡皮筋的條數(shù)后，紙帶上反映小車勻速運動的點數(shù)和點的位置，不一定都在事先的設(shè)定點（即用一條橡皮筋拉小車，橡皮筋剛好恢復(fù)原長時紙帶上的點）處。
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(biāo)教材必修一的“表達(dá)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(xùn)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(xué)習(xí)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(dǎo)結(jié)合起來教學(xué)。這樣設(shè)計還有一個目的，那就是解決課程改革中教學(xué)內(nèi)容多而課時緊張的矛盾，提高課堂教學(xué)效率。師：今天，我們一起來學(xué)習(xí)“寫人要凸顯個性”。這兩堂課分四個步驟來完成：一、先學(xué)習(xí)教材中關(guān)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；
人教版新課標(biāo)高中物理必修1探究加速度與力、質(zhì)量的關(guān)系教案2篇
三、制定實驗方案的兩個問題：1．怎樣測量（或比較）物體的加速度：引導(dǎo)學(xué)生思考、討論并交流。學(xué)生可能會提出下面的一些方案：方法一：測出初速度為零的勻加速直線運動的物體在 時間內(nèi)的位移 ，則 ；方法二：在運動的物體上安裝一條打點計時器的紙帶，根據(jù)紙帶上打出的點來測量加速度；方法三：測出兩個初速度為零的勻加速運動的物體在相同的時間內(nèi)發(fā)生的位移 、 ，則 ；方法四：測出兩個初速度為零的勻加速運動的物體在相同的位移內(nèi)所用的時間 、 ，則 ；2．怎樣提供并測量物體所受的恒力：教師提出：現(xiàn)實中，除了在真空中拋出或落下的物體（僅受重力）外，僅受一個力的物體幾乎是不存在的。然而，一個單獨的力作用效果與跟它大小、方向都相同的合力的作用效果是相同的，因此，實驗中力 的含義指物體所受的合力。以在水平軌道上用繩牽引小車加速運動為例，小車受到四個力的作用，即重力、支持力、繩的拉力和軌道對小車的摩擦力（當(dāng)物體運動的速度比較小時，我們可以忽略空氣的阻力）。
人教版新課標(biāo)高中物理必修1探究加速度與力、質(zhì)量的關(guān)系教案2篇
1．加速度與力的關(guān)系：實驗的基本思路是保持物體的質(zhì)量不變，測量物體在不同的力的作用下的加速度，分析加速度與力的關(guān)系。有了實驗的基本思路，接下去我們就要準(zhǔn)備實驗器材，以及為記錄實驗數(shù)據(jù)而設(shè)計一個表格。為了更直觀地判斷加速度與力的數(shù)量關(guān)系，我們以 為縱坐標(biāo)、 為橫坐標(biāo)建立坐標(biāo)系，根據(jù)各組數(shù)據(jù)在坐標(biāo)系中描點。如果這些點在一條過原點的直線上，說明 與 成正比，如果不是這樣，則需進一步分析。2．加速度與質(zhì)量的關(guān)系：實驗的基本思路是保持物體所受力不變，測量不同質(zhì)量的物體在該力作用下的加速度，分析加速度與質(zhì)量的關(guān)系。有了實驗的基本思路，接下去我們就要準(zhǔn)備實驗器材，以及為記錄實驗數(shù)據(jù)而設(shè)計一個表格。為了更直觀地判斷加速度與質(zhì)量的數(shù)量關(guān)系，我們以 為縱坐標(biāo)、 為橫坐標(biāo)建立坐標(biāo)系，根據(jù)各組數(shù)據(jù)在坐標(biāo)系中描點，根據(jù)擬合的曲線形狀，初步判斷 與 的關(guān)系是反比例函數(shù)。再把 圖像改畫為 圖像，如果是一條過原點的斜直線，說明自己的猜測是否正確。
人教版新課標(biāo)高中物理必修2萬有引力定律說課稿2篇
學(xué)生中存在這樣的問題：既然宇宙間的一切物體都是相互吸引的，那么為什么沒有吸引到一起？為了解決這個問題，安排了例題2例2、兩物體質(zhì)量都是1kg，相距1m，它們間的萬有引力是多少？通過本題，讓學(xué)生認(rèn)識到一般物體間的引力極小，不用考慮。那么，質(zhì)量很大的天體為什么沒被吸引到一塊？從而引出下節(jié)課題。4.課堂小結(jié)：本節(jié)課，從天體運動出發(fā)，通過推理證明，形成理性認(rèn)識，再結(jié)合例題習(xí)題使學(xué)生的理性認(rèn)識再反饋到具體事實。形成實踐-理論-實踐的認(rèn)知循環(huán)，順應(yīng)了認(rèn)知規(guī)律.。本共設(shè)計了很多問，能讓學(xué)生想的盡量讓學(xué)生想、能學(xué)生說的盡量讓學(xué)生說、能讓學(xué)生做的盡量讓學(xué)生做，全面發(fā)展學(xué)生的各方面能力。再通過作業(yè)和探究性課題使學(xué)生的思維活動在時空上得以延續(xù)。5.布置作業(yè)：布置作業(yè)時刻意安排引入：萬有引力、重力、向心力、三者的聯(lián)系，通過引導(dǎo)學(xué)生對比結(jié)果，從中發(fā)現(xiàn)問題：萬有引力與重力向心力的關(guān)系與區(qū)別，為下節(jié)知識的難點突破作好了鋪墊。

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(guān)系？進一步求證這兩個力的大小關(guān)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(jié)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(fù)之分？講清作用力與反作用力作用的受力物體不同，并和學(xué)生討論如何做才會獲勝。回應(yīng)課前問題：“以卵擊石”為什么雞蛋碎？

（3）內(nèi)陸和中西部城鎮(zhèn)主要以煤和火電為主；廣大農(nóng)村和邊遠(yuǎn)地區(qū)大多正從使用農(nóng)作物秸稈等生物能源。（4）人均能源資源不足。我國是世界第三大能源生產(chǎn)國和第二大能源消費國，而我國能源短缺，特別是油氣資源短缺已成為制約我國經(jīng)濟發(fā)展的重要因素。相關(guān)數(shù)據(jù)——煤炭、石油和天然氣的人均資源占有量只有95t，世界平均值為209t，約是世界人均值的1/2；我國人均石油可采儲量3t，世界平均值為28t，約為世界平均值的1/10。我國人均能源消費量不足1.2噸標(biāo)準(zhǔn)煤，居世界89位，不足世界人均能源消費水平的一半，僅占發(fā)達(dá)國家的1/5～1/10。其中人均消費650kg標(biāo)準(zhǔn)煤，是世界平均額的95%；人均消費石油相當(dāng)145kg標(biāo)準(zhǔn)煤，為世界平均數(shù)的16.8%；人均消費天然氣相當(dāng)17.7kg標(biāo)準(zhǔn)煤，為世界平均數(shù)的3.9%；人均消費電力501.5kWh，為世界平均水平的25%。（5）是能源消費結(jié)構(gòu)不合理，突出存在著一低兩高：即電能消費比例低，非商品生物能源消費量高，一次性商品能源消費中原煤消費比重高。原煤消費達(dá)到75%，遠(yuǎn)高于26.2%的世界平均水平。
