新人教版高中英語必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教學設計二
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

人教版高中歷史必修3從“師夷長技”到維新變法說課稿2篇
(一)、教材地位：我說課的內(nèi)容是人教版高二歷史（必修3）第五單元《從“師夷長技”到維新變法》。本課主要講述了鴉片戰(zhàn)爭后中國思想界發(fā)生的巨大變化，所講述內(nèi)容對中國近百年的歷史走向，對近代中國政治發(fā)展所產(chǎn)生的影響是至關重要的，所以這節(jié)課在教材中具有重要的地位和作用，同時也是本冊書中的重要章節(jié)。(二)、課標要求：《高中歷史新課程標準》對這一節(jié)內(nèi)容作了這樣的要求：了解鴉片戰(zhàn)爭以后中國人學習西方 尋求變革的思想歷程，理解維新變法思想在近代中國社會發(fā)展中所起的作用。(三)、教學目標：根據(jù)課標要求、教材內(nèi)容和學生的具體情況，確立以下教學目標：1、知識與能力：（1）識記：林則徐被稱為“開演看世界的第一人”；魏源的“師夷長技以制夷”思想；洋務派“師夷長技以自強”思想；早期維新思想和90年代維新思想；
人教版新課標高中物理必修2圓周運動說課稿3篇
設計意圖：通過設疑、討論及學生的親身體驗與教師的引導，得到描述圓周運動快慢的兩個物理量，也就成功的打破了學生在認識上的思維障礙，突破了物理概念教學的難點。在解決線速度和角速度的問題之后，我將引領學生學習勻速圓周運動的概念以及勻速圓周運動中線速度、角速度的特點。并引出勻速圓周運動中周期、轉(zhuǎn)速的知識。為了加深學生對線速度、角速度與半徑關系的認識，我設計了第三個學生體驗活動：四名學生以我為圓心做圓周運動，四名學生始終并列，這時里圈同學走動不急不慢，而外圈同學則要小跑。通過學生的活動，不難發(fā)現(xiàn)在角速度相同的情況下，半徑越大的線速度也越大。定性的得到了線速度、角速度與半徑的關系。接下來讓學生利用所學知識推導線速度、角速度與半徑的關系。設計意圖：這樣就通過設疑、學生猜想、體驗、推導的方式得到了結論，突破了本節(jié)課的難點即線速度、角速度與半徑的關系。

（三）教學重、難點1、教學重點：結合課文，了解演講辭針對性強、條理清楚、通俗易懂、適當?shù)母星樯实忍攸c。2、教學難點：深入理解文章內(nèi)涵，聯(lián)系現(xiàn)實，體會本文的現(xiàn)實意義二、說學情高中學生在初中階段已經(jīng)接觸過演講辭了，對演講詞的特點已經(jīng)有了一些基本的知識，因此本輪的教學應該讓他們在此基礎上有所提高。本文是學生在高中階段第一次接觸演講辭，有必要讓他們了解演講辭的特點及課文如何體現(xiàn)這些特點的。隨著年齡的增長，生活閱歷的增加，高中學生正逐漸形成自己對世界、對人生的看法，蔡元培先生的這篇文章能很好地激發(fā)他們對當前的高中學習和未來的大學生活進行思考。此外，學生對北大的歷史及蔡元培先生作這番演講的時代背景了解不深，應作出補充說明。
人教版高中語文必修3《杜甫詩三首 秋興八首》說課稿2篇
師：“兩開”是什么意思?。孔⒔饫锸窃趺凑f的？第二次開，也就說他在這個地方已經(jīng)待了兩年了，這里是他回家的路途中，是不是？路途中他停留了兩年時間。好的，你先請坐。你覺得殘菊不能兩開，在理解上好像存在一些誤差。趙勇：因為菊花古往今來代表著對家鄉(xiāng)的思念。師：菊花代表對家鄉(xiāng)的思念？（下面學生齊笑）這種說法牽強了些，菊花在古代象征著高潔，梅蘭竹菊是四君子嘛。趙勇：寫這首詩時，他已經(jīng)打算回故鄉(xiāng)了，所以不應該寫“殘菊”，寫“殘菊”的話……師：事實上，他回不了故鄉(xiāng)。好的，請坐。再想想，“殘菊”意味著什么？破敗?！皡簿铡蹦?？茂盛。那這里說“兩開他日淚”，“兩開”是什么意思？開了兩了次了，這說明他在這里已經(jīng)待了兩年了。那“他日淚”又是什么意思？趙勇：應該是他看到這里的菊花開得這么茂盛，就想到了故鄉(xiāng)的菊花也是開的茂盛的時候。如果是“殘菊”的話，那故鄉(xiāng)的菊也會開得很殘敗。（下面學生齊笑）
人教版高中語文必修3《杜甫詩三首 詠懷古跡》說課稿2篇
第三，說教學重點和難點。根據(jù)課程標準的具體要求、學生實際和社會實際以及教材的邏輯結構和教學體系，我認為本課的重難點是以下幾個方面。教學重點：1．理解王昭君的形象2．深入理解杜甫在詩中的情感教學難點：理解寓意，把握主旨。第四，說教法與學法。教法：根據(jù)課文特點和學生實際情況，以誦讀法（示范朗讀、學生齊讀）、問題探究法、點撥法、討論分析法進行教學。首先激發(fā)學生學習本文的興趣；然后引導學生反復吟哦誦讀，在讀的過程中質(zhì)疑、思考、品析、鑒賞；最后在教師適當?shù)狞c撥下，在集體的熱烈討論中，理解作者的感情，得到新的認識。（解說：使學生在教師的主導下圍繞中心議題發(fā)表各自的意見，相互交流，相互啟發(fā)，相互爭議，激發(fā)他們主動去獲取知識，培養(yǎng)健康情感。）
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。

人教版高中歷史必修1甲午中日戰(zhàn)爭說課稿
3．甲午中日戰(zhàn)爭中國戰(zhàn)敗的原因 對于“中國戰(zhàn)敗的原因”這一難點的突破，主要通過設置問題“中國之敗敗在實力遜于日本嗎？”通過幻燈片全方位分析其實中國的綜合國力當時是強于日本的。并且在戰(zhàn)前，日本毫無取勝的把握。讓學生結合剛學習過的戰(zhàn)爭原因和經(jīng)過進行討論，從多方面分析中國戰(zhàn)敗的原因。經(jīng)過討論，學生可以得出以下結論：避戰(zhàn)自保方針，沒有積極備戰(zhàn)，將領臨陣脫逃，教師肯定并總結答案進行補充。中日對比：中國士兵出身農(nóng)民，軍事訓練落后，散兵游勇；日本士兵出身武士，訓練有素；中國將領大多臨陣脫逃，并相互猜忌，受當時惡劣的官風影響；李鴻章深知北洋海軍實情，缺乏軍費，軍備廢弛。為政治資本奉行避戰(zhàn)自保政策，慈禧太后挪用海軍軍費過壽，支持李鴻章。使中方處于被動的局面，一再貽誤戰(zhàn)機。而日本在天皇的帶動下，全民備戰(zhàn)，做了充分的戰(zhàn)爭準備。
