【正文】 around looking for material, strengthen the cooperation between students, enhance the connection between the teachers and students, cultivating students39。 consciousness of , multimedia geography teaching process a learning emphasizes pay attention to the cultivation of students39。 autonomous learning ability, through the use of various techniques to collect information resources create a learning environment to support student learning, greatly promoted the teaching from “teaching” as the center to the transition of the “l(fā)earning” as the way and the layout changes, for example, the impact on the settlement space form, space and time span is very big, students39。 lack of experience, the traditional teaching method is difficult to create am teaching “huaibei transportation way and the influence of layout changes” when did this: first to collect ancient huaibei LiuZi sui and tang dynasties grand canal material video and ancient LiuZi settlement space form, again through the student field trips to obtain now LiuZi transportation and settlement of the groups of materials through the multimedia display, creating problem situation:(1)LiuZi ancient and modern and contemporary what is the main mode of transport?(2)of the ancient and contemporary differ settlement space form?(3)summarize and transportation layout changes in huaibei especially LiuZi lets the student independent discussion e to the conclusion that to understand this abstract use teaching material, on the one hand, greatly improved the students39。 interest in learning, make students more love their home, to practice, on the other hand can pay attention to cultivate students ability to acquire the point, the breakthrough geography learning process, we often encounter some plex abstract the multimedia technology, we can more intuitive for the students to display a variety of geographical phenomenon, facilitate analysis to each kind of as day length of seasonal change is, it is difficult for students to grasp knowledge by using modern education technology, through the production of transparent “framework”, animated simulation night with direct sunlight point move and change, the whole forming process fully displayed in front of based on virtual reality to observe, conclude and conjecture, again to find the conclusion, finally pleted the construction of use of multimedia to reinforce learning and timely feedback positive blackboard practice is hard to find good practices of students or problems, and the use of multimedia teaching, this kind of problem can be well high school geography, for example, the transportation way and the influence of layout changes teaching, lets the student cooperation explore distribution of mercial outlets around the train students display results can direct projection, using multimedia to student achievement let the student to evaluation and expounds is conducive to help the student error correction, and let students understand the methods to solve the problem by parison, points out the typical problems and errors, make every student involved, enhance the students39。 learning short, in the multimedia teaching, the teacher must be in order to improve the teaching quality for the purpose, based on the teaching students learning situation into account, create suitable for students learning of class teaching design, maximum limit makes multimedia technology bined with geography teaching, achieve the purpose of improving teaching quality.第二篇：淺談如何利用多媒體提高數(shù)學(xué)教學(xué)效率淺談如何利用多媒體提高數(shù)學(xué)教學(xué)效率內(nèi)容提要：新時(shí)代的教學(xué)必須以更快的速度、更高的效率、更充分的學(xué)習(xí)活力來適應(yīng)一切。運(yùn)用多媒體課件輔助教學(xué)，改革傳統(tǒng)的課堂教學(xué)模式，極大地提高教學(xué)效率和質(zhì)量，實(shí)現(xiàn)知識(shí)型教育向素質(zhì)型教育的轉(zhuǎn)變。作為一名數(shù)學(xué)教師，我們要讓多媒體進(jìn)入我們的數(shù)學(xué)課堂，使我們?cè)谥R(shí)傳授過程中，音色清晰、畫面形象、影音統(tǒng)一等諸多優(yōu)點(diǎn)于一體，使教學(xué)由抽象到直觀，圖文并茂，聲像兼具，形象生動(dòng)，讓數(shù)學(xué)不再枯燥乏味，激發(fā)學(xué)生學(xué)習(xí)興趣，真正地改變傳統(tǒng)教育單調(diào)模式?，F(xiàn)代教育技術(shù)為教學(xué)過程提供了一個(gè)良好的建構(gòu)主義學(xué)習(xí)環(huán)境，使學(xué)生在與周圍環(huán)境的相互作用的過程中，逐步建構(gòu)起關(guān)于外部世界的知識(shí)，從而使自身認(rèn)知結(jié)構(gòu)得到發(fā)展。運(yùn)用多媒體課件輔助教學(xué)，改革傳統(tǒng)的課堂教學(xué)模式，極大地提高教學(xué)效率和質(zhì)量，實(shí)現(xiàn)知識(shí)型教育向素質(zhì)型教育的轉(zhuǎn)變。作為一名數(shù)學(xué)教師，我們要讓多媒體進(jìn)入我們的數(shù)學(xué)課堂，使我們?cè)谥R(shí)傳授過程中，音色清晰、畫面形象、影音統(tǒng)一等諸多優(yōu)點(diǎn)于一體，使教學(xué)由抽象到直觀，圖文并茂，聲像兼具，形象生動(dòng)，讓數(shù)學(xué)不再枯燥乏味。那么如何使用多媒體提高小學(xué)數(shù)學(xué)教學(xué)的效率呢？一、利用多媒體，激發(fā)學(xué)生學(xué)習(xí)數(shù)學(xué)的興趣多媒體的特點(diǎn)之一就是具體形象、生動(dòng)直觀,能給學(xué)生提供鮮明、生動(dòng)、明晰的視覺形象,能夠激起學(xué)生學(xué)習(xí)的興趣和求知欲,調(diào)動(dòng)學(xué)習(xí)的積極性。利用多媒體技術(shù)可以將聲音和動(dòng)態(tài)圖像相結(jié)合，其生動(dòng)形象的表現(xiàn)方式，在吸引學(xué)生的注意與創(chuàng)設(shè)教學(xué)情境方面，具有其它教學(xué)手段所不可比擬的優(yōu)勢。在數(shù)學(xué)課堂教學(xué)中，很多生活中的情境難以在課堂上展現(xiàn)，這時(shí)，多媒體充分運(yùn)用圖像、聲音、動(dòng)畫、文字等，使輸出的信息生動(dòng)形象。通過創(chuàng)設(shè)情境、渲染氣氛，激發(fā)了學(xué)生學(xué)習(xí)的興趣，提高了數(shù)學(xué)教學(xué)的質(zhì)量和效益。二、利用多媒體，實(shí)現(xiàn)優(yōu)化教學(xué)過程學(xué)生的數(shù)學(xué)學(xué)習(xí)應(yīng)當(dāng)是現(xiàn)實(shí)的、有意義的、富有挑戰(zhàn)性的。小學(xué)生主要能夠理解一些形象思維，對(duì)一些抽象思維的內(nèi)容往往難以理解，更何談應(yīng)用和掌握。數(shù)學(xué)教學(xué)的主要目標(biāo)之一就是如何培養(yǎng)學(xué)生的抽象思維能力。因此，在課堂教學(xué)中教師可以利用多媒體計(jì)算機(jī)圖文并茂、聲像并舉、能動(dòng)會(huì)變、形象直觀等特點(diǎn)，刺激學(xué)生，使抽象的數(shù)學(xué)知識(shí)具體化、形象化。例如：在講述圓柱、圓錐和球的時(shí)候，我們可以通過對(duì)圓柱、圓錐、球的認(rèn)識(shí)推算出面積公式，這時(shí)我們可以利用課件中圖形分、合、轉(zhuǎn)、并、移、展等多種形式的動(dòng)畫，再結(jié)合有關(guān)的必要解說及優(yōu)美的音樂，使學(xué)生身臨其境，產(chǎn)生立體感效應(yīng)，同時(shí)利用啟發(fā)性的提問，引導(dǎo)學(xué)生積極開展思維，自我挖掘各圖形間的內(nèi)在聯(lián)系以及有關(guān)公式的推理模擬，不但能徹底的改變傳統(tǒng)教學(xué)中的憑空想象，同時(shí)還能充分激發(fā)學(xué)生的主動(dòng)學(xué)習(xí)興趣，化被動(dòng)為主動(dòng)，激發(fā)他們的求知欲望。使學(xué)生樂于接受，實(shí)現(xiàn)教學(xué)過程的最優(yōu)化。三、運(yùn)用多媒體突破知識(shí)重難點(diǎn)每一個(gè)知識(shí)點(diǎn)都有其重點(diǎn)、難點(diǎn)，教學(xué)重點(diǎn)難點(diǎn)是否能巧妙突破是一堂課能否成功的關(guān)鍵。在教學(xué)內(nèi)容中，有一些知識(shí)比較抽象，學(xué)生學(xué)起來有思維障礙，若用常規(guī)的教學(xué)手段教學(xué)，不易向?qū)W生表述清楚。而恰當(dāng)運(yùn)用多媒體進(jìn)行教學(xué)，可解決教師難以講清、學(xué)生難以聽懂的內(nèi)容，它無疑是教師在教學(xué)過程中突出教學(xué)內(nèi)容重點(diǎn)、突破教學(xué)難點(diǎn)的有效手段。在小學(xué)教學(xué)中，內(nèi)容豐富的插圖是教材的重要組成部分，但插圖是靜止的，我們可以把靜止的插圖變成動(dòng)感的圖像，我們可以借助多媒體，創(chuàng)設(shè)動(dòng)態(tài)情境，以鮮明的色彩，活動(dòng)的畫面把活動(dòng)過程全面展現(xiàn)出來，那么就可突出知識(shí)重點(diǎn)、突破難點(diǎn)，化抽象為具體。數(shù)學(xué)教學(xué)中的應(yīng)用題有些是比較復(fù)雜難懂的，小學(xué)生理解起來比較困難的。我們可以把抽象的難理解的知識(shí)變成形象的圖畫，在教學(xué)過程中恰當(dāng)?shù)卣故窘o學(xué)生，使這些問題具體化、形象化，幫助學(xué)生建立豐富的思維表象，使學(xué)生對(duì)題中的數(shù)量關(guān)系能有一個(gè)直觀的感受，增強(qiáng)學(xué)生對(duì)這些數(shù)量關(guān)系的理解。為了突破難點(diǎn)，使學(xué)生較好的在教學(xué)這部分內(nèi)容時(shí)，運(yùn)用多
