【正文】 ements is form the lesson , traditional teaching cases are often a result of personal achievement, and teachers form teaching cases according to their understanding of the content of knowledge and teaching design, mainly in the word electronic documents or written disadvantage is that it cannot be Shared and modified in lesson plan design includes teaching material analysis, teaching design, review introduced, interaction between teachers and students, exercises to consolidate, etc.), blackboard writing, teaching reflection and other traditional link, also including courseware, such as links to database, friendship can give full play to the advantage of information technology new a teaching case, full integration of the picture, the text, the sound, like the role of various media, stimulate students39。 interest in biggest feature is to provide links, easy to call, vivid and ①向?qū)W習(xí)者提示的各種教學(xué)信息。②用于對學(xué)習(xí)過程進(jìn)行診斷、評價(jià)、處方和學(xué)習(xí)引導(dǎo)的各種信息和信息處理；③為了提高學(xué)習(xí)積極性，制造學(xué)習(xí)動機(jī)，用于強(qiáng)化學(xué)習(xí)刺激的學(xué)習(xí)評價(jià)信息；④用于更新學(xué)習(xí)數(shù)據(jù)、實(shí)現(xiàn)學(xué)習(xí)過程控制的教學(xué)策略和學(xué)習(xí)過程的控制方法。對于課件理論、技術(shù)上都剛起步的老師來說，POWERPOINT是個(gè)最佳的選擇。因?yàn)椴僮魃戏浅：唵?，大部分人半天就可以基本掌握。所以，就可以花心思在如何在課件中貫徹案例的設(shè)計(jì)意圖上、如何增強(qiáng)課件的實(shí)效性上，既是技術(shù)上的進(jìn)步，也是理論上的深化，通過幾個(gè)相關(guān)案例的制作，課件的概念就會入心入腦了。多媒體課件多媒體教學(xué)課件是指根據(jù)教師的教案，把需要講述的教學(xué)內(nèi)容通過計(jì)算機(jī)多媒體（視頻、音頻、動畫）圖片、文字來表述并構(gòu)成的課堂要件。它可以生動、形象地描述各種教學(xué)問題，增加課堂教學(xué)氣氛，提高學(xué)生的學(xué)習(xí)興趣，拓寬學(xué)生的知識視野，10年來被廣泛應(yīng)用于中小學(xué)教學(xué)中的手段，是現(xiàn)代教學(xué)發(fā)展的必然趨勢。電子課件優(yōu)勢電子課件與傳統(tǒng)的教科書相比，它的優(yōu)勢在于資源的豐富性和學(xué)習(xí)的自主性。電子課件的內(nèi)容非常豐富，包括課本、教案、練習(xí)、自測、參考書籍和相關(guān)案例等，就像一個(gè)小型圖書館，給學(xué)生的學(xué)習(xí)帶來了極大的便利，學(xué)生可以根據(jù)自己具體情況自由把握學(xué)習(xí)的進(jìn)度。電子教案教案是描述如何進(jìn)行一堂課的教學(xué)，通常都是教師書面上的文字，課前備課是一線教師進(jìn)行教學(xué)的重要環(huán)節(jié)，在整個(gè)教學(xué)活動中占有關(guān)鍵作用，備課的成果表現(xiàn)是形成教案。但傳統(tǒng)的教案往往是個(gè)人成果，教師按照自己對知識內(nèi)容的理解和教學(xué)設(shè)計(jì)而形成的教案，主要以word電子文檔或書面形式來表現(xiàn)。其缺點(diǎn)是不能及時(shí)共享和修改。電子教案的設(shè)計(jì)既包括教材分析、教學(xué)設(shè)計(jì)（復(fù)習(xí)引入、師生交流互動、練習(xí)鞏固等）、板書、教學(xué)反思等傳統(tǒng)環(huán)節(jié)，還包括課件、資料庫、友情鏈接等能夠充分發(fā)揮信息技術(shù)優(yōu)勢的新環(huán)節(jié)。即在一個(gè)教案中，充分整合圖、文、聲、像等各種媒體的作用，激發(fā)學(xué)生的學(xué)習(xí)興趣。其最大的特點(diǎn)是提供鏈接，便于調(diào)用，生動直觀。第五篇：2014人教版新目標(biāo)英語八年級下冊Unit3 基礎(chǔ)習(xí)題新版標(biāo)八下Unit 3基礎(chǔ)知識挑戰(zhàn)一．根據(jù)句意及漢語提示補(bǔ)全句子 you ________________(疊)your clothes when you were five? 洗餐具)after meal at )。 does your mother usually ________________(打掃客廳)？ always ________________（幫助處理）some housework after )the floor, you can go boy ________________(不喜歡)eating rice day after always ________________(帶)her dog for a walk after sees this ________________(雜亂), she will get gets bad grades every time because he plays puter games ________________(總是，一直)after was afraid of losing his ____________(獨(dú)立性). should not ____________(扔)rubbish everywhere in order to provide a clean cut my ____________(手指)。 people ____________ ____________(依靠)their parents too a ____________(雜亂，不整潔)！I can’t stand mother ________ a big birthday cake for me last often ________ some shopping on you like to ________ cakes? want to be outside because I hate to ________ I use your puter?No, you have to ______ , working , work ’t, work ’t, work on you please do the cleaning? , I’m afraid I can’ , B and C you buy ____ useful books for her?Sorry, but I don’t have ____ , , , , some have a look at your new dictionary, please? you I like I long may I _____ your bike?For a you mustn’t _____ it to , , , borrow out out it it out out some good apples from the box, and ______ away the told him the news ______ he came back yesterday.(I didn’t tell him the news _______ he came back yesterday.) soon was sleeping ______ Millie was reading a know many people do am am do I , , , , chores’clock every order order soon as students, please read every sentence you are, _______ mistakes you’ll more carefully, the more careful, the less more carefully, the more carful, the
