一、利用信息多媒体激发学生学习兴趣通过制作多媒体教学软件，还可以将各种不同的信息，如数据、文字、图像、动画、声音等有机集成在一起，进而展示事物的本质特征与内在联系，使抽象的图形、数字，呆板的文字，变成赏心悦目的画面，对学生进行多重感官的刺激，有利于创造一种生动活泼的教学环境，激发学生学习兴趣。教学时我们可以利用实物投影仪等多种教育技术，使学生真实地看到作者在文中所状之物，所写之景，如美丽的圆明园、壮丽的长江三峡、笔陡的华山、汶川大地震的感人场面等等，让学生从视觉、听觉上全方位的感受。这种对照学习，无疑有助于提高学生的阅读能力、理解能力和写作能力，形色共现，声情并茂，能取得比传统教学手段更理想的教学效果。二、利用多媒体技术，培养学生的自主性学习随着多媒体技术的成熟，电化教学已成为课堂教学中不可或缺的一部分。无论是课前导入、精读欣赏、重难点突破还是讨论探究，时时都可以见到多媒体技术的身影。然而，如果把信息技术这一有力武器交给学生，让学生置身于网络环境中，学生失去了教师这根“拐杖”，必然得打破原有的学习方法和时间安排，放开手脚，自己去针对问题，解决疑问，寻找答案。学生必然能充分发挥主观能动性，打破被动学习的局面，逐渐形成适合自己的自主探究的学习方式。三、巧妙结合语文学科的特点，运用多媒体技术语文新课程标准明确指出，工具性和人文性的统一，是语文课程的基本特点。语文学习更多的注重学习中人文精神的熏陶与情感的交流，注重以真情感染读者，以形象唤起美感，以意境领悟主旨，以培养语言意识和语文习惯为目标。而多媒体课件里的文字、声音、图片、图像等极大满足了学生感官需求,激发了学生学习兴趣，缩短学生从形象思维到抽象思维的距离，达到“启其所感，导其所难”的目的。从这一点看，多媒体辅助语文教学主要表现在创设情境，激发兴趣这两个方面。以皮亚杰为代表的认知心理学家提倡的建构主义学习理论，把“情境”列为学习环境四大要素之首。他们认为，学习总是与一定的社会文化背景即“情境”相联系的，在实际情境下进行学习，可以激发学生的联想思维，使学习者能利用自己原有认知结构中的有关经验，去同化和索引当前学习到的新知识，从而在新旧知识之间建立起联系，并赋予新知识以某种意义。

termIn 1965 the term Multi-media was used to describe the Exploding Plastic Inevitable, a performance that combined live rock music, cinema, experimental lighting and performance In the intervening forty years the word has taken on different In the late 1970s the term was used to describe presentations consisting of multi-projector slide shows timed to an audio In the 1990s it took on its current In common usage the term multimedia refers to an electronically delivered combination of media including video, still images, audio, text in such a way that can be accessed [1] Much of the content on the web today falls within this definition as understood by Some computers which were marketed in the 1990s were called "multimedia" computers because they incorporated a CD-ROM drive, which allowed for the delivery of several hundred megabytes of video, picture, and audio Word usage and contextSince media is the plural of medium, the term "multimedia" is a pleonasm if "multi" is used to describe multiple occurrences of only one form of media such as a collection of audio CD This is why it's important that the word "multimedia" is used exclusively to describe multiple forms of

pages at Books may also be considered non-linear if the pages are accessed non- The term "video", if not used exclusively to describe motion photography, is ambiguous in multimedia Video is often used to describe the file format, delivery format, or presentation format instead of "footage" which is used to distinguish motion photography from "animation", motion Multiple forms of information content are often not considered multimedia if they don't contain modern forms of presentation such as audio or Likewise, single forms of information content with single methods of information processing ( non-interactive audio) are often called multimedia, perhaps to distinguish static media from active UsageMultimedia finds its application in various areas including, but not limited to, advertisements, art, education, entertainment, engineering, medicine, mathematics, business, scientific research and spatial temporal Several examples are as follows:Creative industriesCreative industries use multimedia for a variety of purposes ranging from fine arts, to entertainment, to commercial art, to journalism, to media and software services provided for any of the industries listed An individual multimedia designer may cover the spectrum throughout their Request for their skills range from technical, to analytical, to CommercialMuch of the electronic old and new media utilized by commercial artists is Exciting presentations are used to grab and keep attention in Industrial, business to business, and interoffice communications are often developed by creative services firms for advanced multimedia presentations beyond simple slide shows to sell ideas or liven-up Commercial multimedia developers may be hired to design for governmental services and nonprofit services applications as Entertainment and fine artsIn addition, multimedia is heavily used in the entertainment industry, especially to develop special effects in movies and Multimedia games are a popular pastime and are software programs available either as CD-ROMs or Some video games also use multimedia Multimedia applications that allow users to actively participate instead of just sitting by as passive recipients of information are called Interactive M In the Arts there are multimedia artists, whose minds are able to blend techniques using different media that in some way incorporates interaction with the One of the most relevant could be Peter Greenaway who is melding Cinema with Opera and all sorts of digital Another approach entails the creation of multimedia that can be displayed in a traditional fine arts arena, such as an art Although multimedia display material may be volatile, the survivability of the content is as strong as any traditional Digital recording material may be just as durable and infinitely reproducible with perfect copies every EducationIn Education, multimedia is used to produce computer-based training courses (popularly called CBTs) and reference books like encyclopedia and A CBT lets the user go through a series of presentations, text about a particular topic, and associated illustrations in various information Edutainment is an informal term used to describe combining education with entertainment, especially multimedia Learning theory in the past decade has expanded dramatically because of the introduction of Several lines

should always be a landmark, able to be accessed from anywhere within a multimedia ---------------- - Multimedia is more than one concurrent presentation medium (for example, on CD-ROM or a Web site) Although still images are a different medium than text, multimedia is typically used to mean the combination of text, sound, and/or motion Some people might say that the addition of animated images

多媒体技术发展趋势 1、发展趋势状况 总的来看，多媒体技术正向二个方而发展：一是网络化发展趋势，与宽带网络通信等技术相互结合，使多媒体技术进入科研设计、企业管理、办公自动化、远程教育、远程医疗、检索咨询，文化娱乐、自动测控等领域；二是多媒体终端的部件化、智能化和嵌入化，提高计算机系统本身的多媒体性能，开发智能化家电。 迎接21世纪国际竞争的挑战和教育改革的实践，由于技术的进步，特别是信息化步伐加快，使这一教育观念转变过程，不仅仅是思想解放，更是一个实践推动的过程。数字化技术将文件处理带入了新的领域，让人们可以用更快的速度生产文件，用更便捷的方式修改图像和文件，利用网络通讯把图像和文件迅速地传到四面八方。经过数字压缩，从根本上解决了录像带资源长期保存的问题。未来的人们需要某一内容时，可以通过网络调出，在网络终端上阅读，满意时，再从终端打印机上打印出来。因特网就是在这种背景下，不知不觉地走近了我们的生活。1997年，中国媒体对网络的报道不断升温，因特网信息服务提供商开始了商业运作，反映到教育领域，这些技术的变化，推动了学校电化教育的大力普及。很多在过去传统教育手段和方法下难于解决的问题，在今天的数字化方式下迎刃而解了。 2、蕴藏的巨大发展空间 先进的多媒体技术蕴藏着巨大的发展空间。 荷兰电子制造业巨头飞利浦电子公司(PhilipsElectronics)前天表示，它正在准备批量生产一种体积小巧、类似书籍大小的显示器，消费者将可以利用这种显示器下载报纸和杂志，然后把显示器卷起来收藏好。这种五英寸的显示器可以呈现出精细的影像，并能折放进钢笔大小的存放器中。如果它与手机相连接，还能用以下载网页、书籍或电子邮件。飞利浦表示，它利用由塑料制成的电子电路研发出了上述单色显示器。飞利浦研究部门发言人表示：“我们将可以批量生产这种显示器，它已经不再是一个研究项目，我们将建造一个试点生产线，预计可以在2005年投产，届时年产量可以达到100万台。” 时代的步伐把我们带到了21世纪，面对信息时代，世界上任何一件事物都是由信息组成的。网络、商务已经变成昨天的话题。人们工作依赖于信息，生活还是依赖于信息。作为商务活动中最传统的组成之一的名片依旧据占着历史。为什么没有多媒体名片？为什么没有internet名片？为什么没有pda名片？传统的名片以纸张为介质，传达姓名、电话、公司等极为有限的信息。对于今天的信息时代，这些信息显得有点“寒酸”。这点儿三言两语要把个人或公司介绍的比较详细是不可能的。怎样实现用名片的形式来表达更多的内容和完整的企业形象呢？多媒体技术给出了答案。把声音、影视，把交互，以至于三维、四维的元素以多媒体的形式表现在名片上，使多媒体技术应用的更广。 其实多媒体名片只是作为生活多媒化的起点，倡导多媒体的多元化，使多媒体不只应用在多媒体光盘上，在“蓝牙”、“pocket”等新技术下使多媒体技术、概念真正的走进生活，走进各个领域。 设计和技术是同等重要的，关键是把“前”的设计与“新”的技术相互结合，用在设计上。首先是商务活动信息时代化的概念得以应用。其次是多媒体设计艺术、技术的大众化，并突出公司的形象。目前国内外还没有把多媒体名片或internet名片作为项目进行开发和设计制作。传统的名片还是统一着天下，只有多媒体光盘性质的公司简介。以多媒体名片作为一个多媒体应用的一个缩影，国外在多媒体应用上要领先于我们，比如数字化多媒体冰箱，数字化多媒体房屋等。虽然我们硬件，软件和国外有着一定的差距，但是观念上我们要赶超国外。 2003年，市场研究公司ForresterResearch预测，苹果计算机公司进入音乐下载服务市场将使该公司在这个迅速扩张的市场中获得一块份额。这家公司在5月15日发表的一篇研究报告中预测，欧洲数字音乐下载服务服务市场到2007年将价值13亿欧元。这个市场2003年的收入只有2,400万欧元，但是将占2007年全部音乐销售收入的13%。美国数字音乐下载服务服务市场到2007年将价值20亿美元。Forrester公司称，这些收入大多数来自个人下载，并不是基于订阅的服务。更过的合法服务的出现和更高的宽带网普及率将推动这种增长。研究分析师RebeccaJennings表示，最近EMI公司和苹果公司宣布进入这个市场的消息表明，主要音乐公司和技术公司现在正开始认真对待未来的数字音乐。虽然美国合法的音乐下载市场已经摆脱了障碍，在2002年达到了1,500万美元，但是，欧洲市场落后了。这是因为正式的服务仅集中在美国，欧洲家庭宽带网的普及一直比较缓慢。但是，在今后几年里，数字音乐的传播将迅速增长。这篇报告预测，消费者的需求将迫使唱片公司向欧洲市场扩张。报告指出，宽带网用户下载MP3音乐的人数可能会比窄带用户多123%。 Jennings表示，欧洲消费者最喜欢购买单曲唱片。在2002年，欧洲人购买了大约65亿张单曲唱片，而美国单曲唱片仅销售了900万张。Jennings预计，欧洲消费者一般都下载单曲唱片，在欧洲的数字音乐销售将有42%是单曲唱片。在2007年，成套唱片将占下载音乐的49%。分析人士表示，还有基于订阅的服务。到2007年，将有200万用户为这些服务支付25亿欧元。 20世80年代，美国APPLE公司成立计算机多媒体实验室，主要研究计算机技术同多种信息媒体相结合，并首次推出了MACHITOSH系统机，标志着早期多媒体技术的兴起。进入20世纪90年代，多媒体计算机技术迅速发展，给信息传播带来了一场革命。现代意义上的多媒体以计算机技术作为支撑，不仅具有计算机所固有的存储记忆、高速运算、逻辑判断、自行运行等功能，还采用了图形窗口、交互界面、语音识别和触摸屏等先进方式，使计算机不仅具有了处理文本、图形、音频、视频的能力，并能够用人类习惯的方式、图像、声音，生动逼真地传播和表达信息，与人类交流。多媒体技术的广泛应用促进了多媒体语音室、多媒体计算机模拟实验室、电子图书室、多媒体教学管理等的蓬勃发展。此外，网络的出现与发展，使以因特网（INTERNET）为主要标志的网络技术构成了现代技术文化的重要部分，联系上亿人的因特网将人类带入了一个全新的数字化时代，拓展了人类的第二生存空间——网络社会。在网络社会的大背景下，网络技术与教育更是结下不解之缘：美国在1998年公布了INTERNET计划，宣布要使每一所学校、每一间教室、每一家庭和每一个美国公民都能享受INTERNET带来的全新的学习环境；英国政府建议成立网上工业大学，并推出“全国学习网”，目标是到2002年使英国2万所中小学全部进入因特网；我国教育部1999年推出《面向21世纪教育振兴行动计划》将校园网的构建提到日程上来，2000年4月中国基础教育网正式开通，同年10月国家教育部宣布全面实施“校校通”工程，目标是在未来的5－10年内使全国90％以上的中小学能与网络联通，到2005年使所有大学和一千所中小学上网。 3、在网络教学上的发展 “多媒体”与“网络”的联姻促成了“多媒体网络教学”的产生。作为信息时代的教学媒体，多媒体网络技术所具有的集成性、交互性、可控性、信息空间主体化和非线性等特点使其与黑板、粉笔、挂图等传统媒体有质的区别。多媒体与网络技术特有的优点使其对教学的介入，不仅改变了教学手段，而且对传统的教学、教学模式、教学内容、教学方法等产生了深远的影响，极大地冲击了机器工业时代“大批量生产”形式的教学。目前这一技术正向着交互性、非线性化、智能化和全球化的方向推进。 三、总结 从多媒体技术的发展趋势来看，多媒体技术的数字化将会是未来技术扩张的主流，而作为多媒体技术赖以存在和发展的重要基石，数字多媒体芯片技术将成为未来多媒体技术革命中的焦点，不管是从以PC技术为依附的计算机多媒体应用，到移动通信业务的各种多媒体实现，以及未来3C时代各种电子化装置的多媒体大融合，数字多媒体芯片都是无可置疑的主角
