19、）教學(xué)目的和要求1、了解什么是信息；2、了解如何描述信息以及對信息進(jìn)行獲取、傳遞、處理的各種技術(shù)；3、知道計算機(jī)技術(shù)和通信技術(shù)是兩種重要的信息技術(shù)；4、了解信息高速公路；教學(xué)重點(diǎn)與難點(diǎn)：信息的各種心態(tài)及其本質(zhì)含義。教學(xué)方法：1 、從感性認(rèn)識到理性認(rèn)識，啟發(fā)學(xué)生對問題深入思考。2、電腦動畫課件教學(xué)。教學(xué)準(zhǔn)備：1 、電教室內(nèi)利用電腦播放自制的教學(xué)課件。2、課前打開電腦。教學(xué)過程一、新課引入1、什么是信息？你知道嗎？（學(xué)生回答）簡單地說，信息就是指對人么有用的數(shù)據(jù)、消息。（有用，即有價值。信息具有價值）2、信息無處不在，無時不有。（舉例啟發(fā)后，請學(xué)生自己舉例）只要我們留意一下周圍世界， 就會發(fā)現(xiàn)信息

20、無處不在， 無時不有。十字路口的信號燈 教室里的板書，掛圖 圖書館里的書報 春節(jié)聯(lián)歡晚會的現(xiàn)場直播 大自然也無時 無刻不在向我們傳發(fā)出各種各樣的信息 可用幻燈片展示以上圖片二、新課教學(xué)解釋：“ 一、信息通常是指數(shù)據(jù)、消息中所含的意義?！笨茖W(xué)角度研究的信息主要指：一是經(jīng)過計算機(jī)技術(shù)處理的資料和數(shù)據(jù)，如文字、 圖形、 影像、聲音等；二是經(jīng)過科學(xué)采集、存儲、復(fù)制、分類、檢測、查找等處理后的信息產(chǎn)品的集合。信息是事物運(yùn)動的狀態(tài)和存在方式而不是事物本身。它必須借助某種符號才能表現(xiàn)出來，而這些符號通常人們用數(shù)據(jù)來記錄它?！岸?、信息技術(shù)主要是指人們獲取、存儲、傳遞、處理信息的各種技術(shù)，計算機(jī)技術(shù)和通訊技術(shù)是

21、兩種重要的信息技術(shù)?！?利用電腦動態(tài)展示以下三種重要的信息技術(shù)“1 、信息的獲取”人腦的大部分信息是通過視覺和感覺器觀獲得的；電腦中的信息主要是通過諸如鍵盤、鼠標(biāo)、語音識別等電腦輸入設(shè)備，掃描儀、傳感器等電子感測裝置來獲取?！? 、信息的傳遞”信息只有通過交流才能發(fā)揮效益。烽火狼煙、飛馬傳書、信鴿遠(yuǎn)飛報紙、電報、電話、廣播微波、光纜、衛(wèi)星、計算機(jī)網(wǎng)絡(luò)“3 、信息的處理”信息處理是指將信息縮小、放大、分類、編輯、分析、計算，加工成某種要求的數(shù)據(jù)形式，如繪制圖形、打印報表等。ngthemanag ementofda ilyeducation,thespiritcom plete system, p

35、1 萬次。此后，在我國計算機(jī)科學(xué)工作者的努力下，計算機(jī)事業(yè)發(fā)展迅速，1964 年每秒鐘運(yùn)算5萬次的晶體管計算機(jī)正式投入運(yùn)行，1973年以集成電路為主要元器件的150 型和 665 型計算機(jī)相繼研制成功。1983 年 2 月每秒鐘運(yùn)算達(dá)1億次的銀河-I 巨型計算機(jī)由中國國防科學(xué)大學(xué)在長沙研制成功，1992 年 11 月每秒鐘運(yùn)算10億次的銀河-II 巨型計算機(jī)研制成功，1997 年 11 月每秒鐘運(yùn)算達(dá)100 億次的銀河-III 巨型計算機(jī)研制成功，標(biāo)志著我國計算機(jī)技術(shù)已經(jīng)快入了國際先進(jìn)行列。第 2 課 計算機(jī)的組成( 信息教案)【教學(xué)目的與要求】(1)了解計算機(jī)組成各部分的名稱和作用。(2)知

49、ome-一一 3教師還可以在計算機(jī)教室中實際地拆裝計算機(jī)，讓學(xué)生感受計算機(jī)的基本組成。如果學(xué)校條件許可還可以分小組，在教師的指導(dǎo)下，在切斷電源的情況下，由學(xué)生拆裝計算機(jī)，親身體驗，了解計算機(jī)的各組成部分。值得注意的是，學(xué)生分小組拆裝計算機(jī)后，必須經(jīng)計算機(jī)教師檢查合格，各接插件均符合要求后才可以通電開機(jī)。在說明計算機(jī)的基本組成時可以分兩個方面來說，一個是從外觀上看，計算機(jī)由主機(jī)箱、鍵盤和顯示器組成，二是從邏輯組成來看，即控制器、運(yùn)算器、存儲器、輸入設(shè)備、輸出設(shè)備，在教學(xué)過程中要講清楚。4講授計算機(jī)軟件時，可以結(jié)合我們的計算機(jī)操作系統(tǒng)、平時利用計算機(jī)處理相關(guān)工作。5通過教學(xué)讓學(xué)生知道，計算機(jī)僅僅由

50、硬件，沒有軟件是沒有辦法進(jìn)行工作的，計算機(jī)再怎么聰明，沒有人編寫系統(tǒng)軟件或應(yīng)用軟件，它也沒有辦法進(jìn)行處理?！緟⒖假Y料】一、計算機(jī)的硬件和軟件現(xiàn)代的計算機(jī)面對用戶的不再是簡單的、由電子線路組成的機(jī)器，而是由硬件和軟件兩部分組成的計算機(jī)系統(tǒng)。1 硬件計算機(jī)硬件從外觀上看主要有主機(jī)箱、鍵盤和顯示器，從邏輯功能上可以分為控制器、運(yùn)算器、 存儲器、輸入設(shè)備、輸出設(shè)備五個部分，一般地又把運(yùn)算器和控制器合稱為中央處理器。判斷一臺計算機(jī)的性能主要看兩個指標(biāo)，第一是CPU 的型號與主頻，第二是總線類型。打開計算機(jī)主機(jī)箱，里面有一塊印刷電路板，這就是計算機(jī)的主機(jī)板(簡稱主板)，一般地，計算機(jī)的重要控件都坐在計算機(jī)

51、的主板上。主板的類型和品種很多，從類型上來說，它們都是以 CPU 來分類的，CPU 芯片在主板上是可以插拔的。主板上還許多部件，如 ROM 、 RAM 、總線槽、插座、電池等。(1)CPUCPU 是中央處理器(Central Processing Unit) 的英文縮寫，它是計算機(jī)的運(yùn)算控制中心，是計算機(jī)中集成度最高、最貴重的一塊芯片。它是由幾千幾千萬個晶體管組成的超大規(guī)模的集成電路芯片。計算機(jī)所有數(shù)據(jù)的加工處理都是在CPU 中完成的。CPU 還負(fù)責(zé)發(fā)出控制信號，使計算機(jī)的各個部件協(xié)調(diào)一致地工作。(2)存儲器內(nèi)部存儲器內(nèi)部存儲器簡稱為內(nèi)存，計算機(jī)要執(zhí)行的程序、要處理的信息和數(shù)據(jù)，都必須先存入內(nèi)

52、存，才能由 CPU 取出進(jìn)行處理。內(nèi)存一般可以分為隨機(jī)讀寫存儲器(RAM) 和只讀存儲器(ROM) 兩種。ROM 中存儲的數(shù)據(jù)只能讀出，而用一般的方法不能寫入。它的最大優(yōu)點(diǎn)是它保存的數(shù)據(jù)在斷電后不會丟失，因此用來保存計算機(jī)經(jīng)常使用且固定不變的程序和數(shù)據(jù)。ROM 中保存的最重要的程序是基本輸入輸出系統(tǒng)BIOS,這是一個對輸入輸出設(shè)備進(jìn)行管理的程序。RAM 中存儲的數(shù)據(jù)可以隨時取出來(稱為讀出)， 也可以隨時存入新數(shù)據(jù)(稱為寫入)或?qū)υ瓉淼臄?shù)據(jù)進(jìn)行修改。RAM 的缺點(diǎn)是斷電以后所存儲的所有數(shù)據(jù)都將丟失。充當(dāng)內(nèi)存的集成電路芯片是做在一小條印刷電路板上的，稱為內(nèi)存條。內(nèi)存條可以很方便地插在主板上，其容

53、量由 8MB、 16MB、 32MB 、 64MB 、 128MB、 256MB 等。在選擇內(nèi)存條時，要考慮容量稍大一些的，也不要插滿槽口，為今后的升級及內(nèi)存的擴(kuò)充留有余地。外部存儲器內(nèi)存的容量有限，且價格較貴，關(guān)機(jī)以后內(nèi)存中所存儲的數(shù)據(jù)就消失了，因此計算機(jī)還必須由外部存儲器(簡稱外存)來存儲數(shù)據(jù)。外存的特點(diǎn)是存儲容量大、價格較低，所存儲的數(shù)據(jù)ectificationand strengtheningthemanagementofda ilyeducation,thespiritofreformshortofthecompletesystem,paycloseattentiontosystem
