小學(xué)數(shù)學(xué)人教版四年級下冊 《加法運算定律》說課稿
（一）教學(xué)內(nèi)容我說課的內(nèi)容是人教版小學(xué)數(shù)學(xué)四年級第三單元第一小節(jié)“加法運算定律”中的第1課時的內(nèi)容，其內(nèi)容包括：第17頁的例1以及18頁的“做一做”第一題、第19頁練習(xí)五第1～3題的部分習(xí)題。（二）教材地位數(shù)學(xué)中，研究數(shù)的運算，再給出運算的定義之后，最主要的基礎(chǔ)工作就是研究該運算的性質(zhì)。在運算的各種性質(zhì)中，最基本的幾條性質(zhì)，通常稱為“運算定律”。加法是數(shù)學(xué)中最基本的運算之一。通過本課時的學(xué)習(xí)，首先，可使學(xué)生對加法的認識從感性上升到理性。其次，用不完全歸納法概括出加法交換律的文字表述形式和字母形式，一方面提高知識的抽象概括程度，另一方面為以后正式講用字母表示數(shù)打下初步基礎(chǔ)。（三）教學(xué)目標1、通過學(xué)習(xí)，使學(xué)生理解和掌握加法交換律，并會運用加法交換律進行簡便計算。2、讓學(xué)生學(xué)會用符號或字母來表示加法交換律。3、培養(yǎng)學(xué)生抽象概括能力，引導(dǎo)學(xué)生由感性認識上升到一定的理性認識。
小學(xué)數(shù)學(xué)人教版六年級上冊《整數(shù)乘法運算定律推廣到分數(shù)》說課稿
今天我說課的內(nèi)容是六年級上冊第一單元的例6、例7《整數(shù)乘法運算定律推廣到分數(shù)》，我的設(shè)計理念是從學(xué)生已有的生活經(jīng)驗出發(fā)，創(chuàng)設(shè)情境、激發(fā)興趣、建構(gòu)知識、發(fā)展思維。下面我從教材、教法和學(xué)法、教學(xué)過程、教學(xué)反思四個方面來對本課進行闡述。一、 說教材1、教材分析：“整數(shù)乘法運算定律推廣到分數(shù)乘法”是在學(xué)生已經(jīng)掌握了分數(shù)乘法計算、整數(shù)乘法運算定律、整數(shù)乘法運算定律推廣到小數(shù)乘法的基礎(chǔ)上進行教學(xué)的。教材從生活入手，通過幾組算式，讓學(xué)生計算出○的左右兩邊算式的得數(shù)，找出它們的相等關(guān)系，總結(jié)出整數(shù)的運算定律對分數(shù)同樣適用。學(xué)好這部分內(nèi)容，不僅培養(yǎng)學(xué)生的邏輯思維能力，而且以后能用本課所學(xué)的使一些分數(shù)的計算簡便，也為以后學(xué)習(xí)用不同方法解答應(yīng)用題起著積極的推動作用。

人教版高中歷史必修1祖國統(tǒng)一大業(yè)教案2篇
教材分析改革開放后我國的綜合國力不斷增強，人民對祖國統(tǒng)一的愿望越來越迫切。本節(jié)課以“一國兩制”構(gòu)想的提出，香港、澳門的回歸和海峽兩岸關(guān)系的發(fā)展為中心，說明實現(xiàn)祖國統(tǒng)一，完成中華民族復(fù)興是歷史發(fā)展的必然。第一目“‘一國兩制’構(gòu)想的提出”主要講述了“一國兩制”的含義及歷史意義。第二目“香港、澳門的回歸”著重講述了香港回歸、澳門回歸的經(jīng)過及歷史意義，這是“一國兩制”成功的實踐。第三目“海峽兩岸關(guān)系的發(fā)展”講述了大陸注重發(fā)展與臺灣的關(guān)系，促進海峽兩岸的經(jīng)濟文化交流與合作，打破了幾十年來海峽兩岸的隔絕狀態(tài)，促進了祖國統(tǒng)一的進程。此外，教材還通過“資料回放”“歷史縱橫”“學(xué)思之窗”等欄目，為學(xué)生學(xué)習(xí)提供了一些詳細的史料。在教學(xué)中要分析圖表資料，引導(dǎo)學(xué)生理解完成祖國統(tǒng)一大業(yè)，實現(xiàn)中華民族的復(fù)興，是任何人也阻擋不了的歷史潮流。
新人教版高中英語必修2Unit 1 Cultural Heritage-Discovering Useful Structure教案一
This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本節(jié)語法思考：定語從句在復(fù)合句中的作用是什么？ 關(guān)系詞有哪些？定語從句在復(fù)合句中的作用相當于形容詞，它在句中作定語修飾名詞或代詞。他們在先行詞和定語從句之間起到聯(lián)系作用，同時在意義上代表先行詞并在定語從句中擔(dān)任一個成分。被定語從句所修飾的詞稱先行詞，定語從句一般放在先行詞的后面。

人教版高中語文必修2《氓》教案2篇
從《詩經(jīng)》的現(xiàn)實主義到屈原的浪漫主義，是中國詩歌發(fā)展的一個里程碑。屈原的騷體詩，依詩取興，引類譬喻，繼承發(fā)展了《詩經(jīng)》的比興傳統(tǒng)。《詩經(jīng)》的比興較為單純，而《楚辭》的比興具有象征的特質(zhì)，往往成為一個形象的系統(tǒng)。《離騷》中香草美人的比興就是范例。楚地本是澤鄉(xiāng)山國，其間頗有疊波曠宇、崇山秀嶺，這些江山的光怪之氣足以搖蕩心靈、催發(fā)麗辭偉句。但騷體詩已沖破《詩經(jīng)》四言詩的固定格式，句式加長而靈活，篇章放大而嚴密，詩采絢麗而貼切，是《詩經(jīng)》之后的一次詩體大解放。有人說，中國歷代詩“莫不同祖風(fēng)騷”，足見其對后代詩歌的影響。先秦時代，《詩經(jīng)》與《楚辭》雙峰并峙，是中國詩史上現(xiàn)實主義與浪漫主義的兩座巍然屹立的坐標。
人教版高中語文必修2《游褒禪山記》教案2篇
1．本文由“不得極夫游之樂”生發(fā)出“盡吾志”的觀點，又由“仆碑”生發(fā)出“深思慎取”的觀點，這兩個觀點彼此有聯(lián)系嗎？作者游褒禪山，本來是一次平常的游歷活動，但卻從中悟出了人生哲理──從前洞后洞游人的多少悟出“夷以近，則游者眾；險以遠，則至者少”，從“入之愈深，其進愈難，而其見愈奇”悟出“而世之奇?zhèn)?、瑰怪、非常之觀，常在于險遠”；由此再引申一步，就得出了“非有志者不能至”的結(jié)論。然后將這次游山而未能“極夫游之樂”的教訓(xùn)升華到理論上來，具體分析了“至”的幾個條件，最后得出“盡吾志”的觀點──這正是“求思之深而無不在”的結(jié)果。由此可見，“盡吾志”的觀點跟“深思慎取”的觀點是有聯(lián)系的：“盡吾志”的觀點是在“深思慎取”的基礎(chǔ)上產(chǎn)生的；有了這個觀點，又能反過來促使人們“深思慎取”，二者是相輔相成的。

人教版高中語文必修2《我有一個夢想》教案2篇
全班齊讀第五段內(nèi)容。請一位同學(xué)分析，接著讓這位同學(xué)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(xué)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.

This unit is about history and traditions. From the opening page, we can know that this unit will introduce the history and traditions around the world. As Marcus Garvey says “A people without the knowledge of their past history, origin and culture is like a tree without roots”, it is important for students to realize the importance and value of knowing the history and traditions and their further meanings. And this part ( listening and speaking ) is divided into two parts: Part A---share views on historic sites, Part B ---talk about a visit to a historic tourist destination. By talking with a foreigner, the speakers introduce the historic attractions and their cultures. Part A is that William, a British student, who was going to visit the Confucius Temple and a Chinese student, Xiao Kong, who was going to the Confucius Temple to meet with the members of the research group, went together and exchanged their views on the Confucius Temple, Confucius, Confucius' descendants and Confucius' educational thoughts.
