人教版高中政治必修3加強思想道德建設(shè)說課稿2篇
師：建立社會主義思想道德體系，必須牢固樹立社會主義榮辱觀。在我們的社會主義社會里，是非、善惡、美丑的界限絕對不能混淆，堅持什么、反對什么，倡導什么、抵制什么，都必須旗幟鮮明。我們堅持以熱愛祖國為榮、以危害祖國為恥，以服務人民為榮、以背離人民為恥，以崇尚科學為榮、以愚昧無知為恥，以辛勤勞動為榮、以好逸惡勞為恥，以團結(jié)互助為榮、以損人利己為恥，以誠實守信為榮、以見利忘義為恥，以遵紀守法為榮、以違法亂紀為恥，以艱苦奮斗為榮、以驕奢淫逸為恥。課堂小結(jié)通過本節(jié)課學習，使我們認識到中國特色社會主義文化建設(shè)的中心環(huán)節(jié)是思想道德建設(shè)，了解什么是社會主義思想道德，為什么要建設(shè)社會主義思想道德體系和怎樣建設(shè)社會主義思想道德體系，大力倡導“愛國守法、明禮誠信、團結(jié)友善、勤儉自強、敬業(yè)奉獻”的基本道德規(guī)范。我們要大力加強社會主義思想道德建設(shè)，為社會主義各項事業(yè)的發(fā)展提供強大的精神動力和方向保證。
人教版高中政治必修3文化與經(jīng)濟、政治說課稿2篇
2、文化反作用經(jīng)濟政治師：經(jīng)濟政治決定文化，那么，文化不是被動消極的呢？生：思考回答：文化反作用經(jīng)濟政治，不同的文化對經(jīng)濟政治的影響不同。師：文化反作用經(jīng)濟政治，對社會發(fā)展有重要影響。文化反作用表現(xiàn)在，文化可以為經(jīng)濟政治的發(fā)展，對社會的發(fā)展，提供方向保證、智力支持和精神動力。（1）文化反作用的體現(xiàn)。師：現(xiàn)代民主國家中，世界民主的先驅(qū)是英國，但英國卻有國王，亞洲民主的先驅(qū)是日本，但日本卻有天皇，其一個重要原因是文化的影響。這說明什么？生：思考發(fā)言……師：不同民族的文化，影響不同民族和國家的歷史和發(fā)展道路。師：中東地區(qū)一直以來都是世界熱點地區(qū)，如巴以沖突、伊拉克戰(zhàn)爭、阿富汗戰(zhàn)爭、基地組織等，其一個重要原因是宗教文化的沖突。這說明什么？生：思考發(fā)言……師：不同文化的沖突，影響社會的和諧安定和世界的和平安寧。
人教版高中地理必修2如何看待農(nóng)民工現(xiàn)象說課稿
b.基于對農(nóng)民工現(xiàn)象的認識以及資料2的分析，請同學辨證的分析出這一現(xiàn)象的利弊——分析問題，當然，這一部分內(nèi)容還是要以學生自主學習、合作學習為主，但教師要給予一定的引導。c.最后，請同學討論，提出自己的意見和建議，應該怎樣解決農(nóng)民工所面臨的問題——解決問題。這一部分要求學生提出自己的見解，不局限于書本，發(fā)揮自身的創(chuàng)造性思維。3.課堂小結(jié)：本節(jié)課作為問題研究課程，探討了我國現(xiàn)階段的農(nóng)民工現(xiàn)象，了解了農(nóng)民工生存的環(huán)境，以及體會了解決農(nóng)民工問題的必要性和重要性，并通過合作探討，得出了一些列解決的方案。著重培養(yǎng)大家對于問題的綜合分析能力。增加大家對農(nóng)民工現(xiàn)象的感性認識，希望大家運用所學知識關(guān)心現(xiàn)實社會中的問題，增強社會責任感，學以致用。
人教版新課標高中物理必修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，但學生在此前的物理學習中可能未曾遇到類似例子，因此引導學生通過交流，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應研究小車在哪個時刻的速度：在橡皮筋剛恢復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，橡皮筋剛好恢復原長時紙帶上的點）處。

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：引導學生思考、討論并交流。學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）。
人教版新課標高中物理必修1運動快慢的描述─速度教案2篇
四、速度和速率學生閱讀教材第18頁相應部分的知識點，讓學生總結(jié)．生：速度既有大小，又有方向，是矢量，速度的大小叫速率，教師引導學生看教材第18頁圖1．3—2．觀察汽車的速度計，討論后說出你從表盤上獲取的有用信息。生：汽車的速率．指針指在相應數(shù)字的瞬間，就表示汽車在那一瞬時的速率是那個值．生：還可以從表盤上直接讀出公里里程．師：日常生活中的“速度”有時指速度，也有時指速率，要看實際的物理情景。[討論與交流]甲、乙兩位同學用不同的時間圍繞操場跑了一圈，都回到了出發(fā)點，他們的平均速度相同嗎?怎樣比較他們運動的快慢?學生討論，體驗平均速度的缺陷，引入平均速率。生1：位移都是零，平均速度等于位移跟發(fā)生這段位移所用時間的比值，所以他們的平均速度都是零。生2：即使一位同學站在原地不跑，他的平均速度也是零啊，可我們運動會上不是這樣比快慢的，如果這樣，那多不公平啊?
人教版新課標高中物理必修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、 為橫坐標建立坐標系，根據(jù)各組數(shù)據(jù)在坐標系中描點。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、 為橫坐標建立坐標系，根據(jù)各組數(shù)據(jù)在坐標系中描點，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。
人教版新課標高中物理必修1運動快慢的描述─速度教案2篇
生：還可以從表盤上直接讀出公里里程．師：日常生活中的“速度”有時指速度，也有時指速率，要看實際的物理情景。[討論與交流]甲、乙兩位同學用不同的時間圍繞操場跑了一圈，都回到了出發(fā)點，他們的平均速度相同嗎?怎樣比較他們運動的快慢?學生討論，體驗平均速度的缺陷，引入平均速率。生1：位移都是零，平均速度等于位移跟發(fā)生這段位移所用時間的比值，所以他們的平均速度都是零。生2：即使一位同學站在原地不跑，他的平均速度也是零啊，可我們運動會上不是這樣比快慢的，如果這樣，那多不公平啊?師：平均速度v=Δx/Δt，甲、乙的位移都為零，所以他們的平均速度也都等于零．在這里平均速度無法顯示他們運動快慢的不同，要用到另一物理量：平均速率．平均速率等于物體運動通過的路程跟所用時間的比值．他們兩人通過的路程相同且都不為零，但所用時間不同．顯然用時短的運動得快，也就是平均速率大．生：這不是我們初中學過的速度嗎?

【教學目標】Ⅰ、學習理解詩歌語言的暗示性特質(zhì)。Ⅱ、根據(jù)詩歌語言的特質(zhì)，進行遷移，領(lǐng)略詩歌的精妙之處，給同學如何鑒賞詩歌提供實感。㈠、導入：各位同學，有個成語叫"一字千金"。對我而言，第一次領(lǐng)略到一個字的分量，是在小學三年級的時候，一次作文評析課上。當時我對自己的文章充滿了期待，希望能得到老師的贊賞。記得老師進來后的第一句話是"有一篇文章，我就沖它用了一個字，我給它打95分。打這樣的高分，對我來說，是極為難得的。"同學都充滿了好奇，老師接著說"這個字就是一個'悟'字。我們的同學都說我學到了，我明白了，我懂得了一個道理，而這位同學卻用了一個'悟'字，難能可貴。"這篇文章不是我的，在羨慕的同時，一個字在文章中的分量就深深的刻在了我的心上。文學作品中，一個字精妙與否，足以決定作品是流光溢彩，還是黯然失色。尤其是我們的古典詩詞，用簡短的幾個字，造就的卻是豐富的情感與博大的意境。讀后滿口余香，卻是妙處難與君說。這跟詩歌的語言是密不可分的。今天，我們就通過《說"木葉"》一文，對中國古典詩詞語言特質(zhì)作一番探幽。

為城市居民提供休養(yǎng)生息的場所，是城市最基本的功能區(qū)．城市中最為廣泛的土地利用方式就是住宅用地．一般住宅區(qū)占據(jù)城市空間的40%—60%。（閱讀圖2.3）請同學講解高級住宅區(qū)與低級住宅區(qū)的差別（學生答）（教師總結(jié)）（教師講解）另外還有行政區(qū)、文化區(qū)等。而在中小城市，這些部門占地面積很小，或者布局分散，形成不了相應的功能 區(qū)。（教師提問）我們把城市功能區(qū)分了好幾種，比如說住宅區(qū)，是不是土地都是被居住地占據(jù)呢？是不是就沒有其他的功能了呢？（學生回答）不是（教師總結(jié)）不是的。我們說的住宅區(qū)只是在占地面積上，它是占絕大多數(shù)，但還是有土地是被其它功能占據(jù)的，比如說住宅區(qū)里的商店、綠化等也要占據(jù)一定的土地， 只是占的比例比較小而已。下面請看書上的活動題。

全班齊讀第五段內(nèi)容。請一位同學分析，接著讓這位同學按他分析的讀一遍。3、4兩自然段的平緩之后，第5段作者的情感再次抬升。為了滿足這種情感的張揚，作一口氣連用了四個排比句式“現(xiàn)在是……時候”，一方面這是情感發(fā)泄的需要，另一方面這種排山倒海的語勢也加強了內(nèi)容的表達，極強地突出了現(xiàn)實為自由、平等而戰(zhàn)的重要性。四、學會演講我們剛才細讀了課文，但讀和講是有區(qū)別的。所謂演講，是一門語言藝術(shù)，它的主要形式是“講”，即運用有聲語言并追求言辭的表現(xiàn)力和聲音的感染力；同時還要輔之以“演”，即運用面部表情、手勢動作、身體姿態(tài)乃至一切可以理解的態(tài)勢語言，使講話“藝術(shù)化”起來，從而產(chǎn)生一種非凡的藝術(shù)魅力。那么，接下來就假設(shè)一下假如你是馬丁·路德·金，你會怎樣去講這篇演講辭。

新人教版高中英語必修2Unit 3 The Internet-Listening &Speaking＆Talking教案一
Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue. There are two specific questions: “how much time do you spend online every day? What do you usually do online?”. The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo. In this part of listening, “oink”； “piggy bank” may cause the students' hearing comprehension limitation. Oink refers to sound word and pig's sound. So, add some oink to my piggy bank is often used to describe "making a little money".1. Guide students to understand the content of listening texts in terms of listening for definitions.2. Cultivate students' ability to define words and understand an investigation interview.
