is media that utilizes a combination of different content The term can be used as a noun (a medium with multiple content forms) or as an adjective describing a medium as having multiple content The term is used in contrast to media which only utilize traditional forms of printed or hand-produced text and still In general, multimedia includes a combination of text, audio, still images, animation, video, and interactivity content Multimedia is usually recorded and played, displayed or accessed by information content processing devices, such as computerized and electronic devices, but can also be part of a live Multimedia (as an adjective) also describes electronic media devices used to store and experience multimedia Multimedia is similar to traditional mixed media in fine art, but with a broader The term "rich media" is synonymous for interactive Hypermedia can be considered one particular multimedia CategorizationMultimedia may be broadly divided into linear and non-linear Linear active content progresses without any navigation control for the viewer such as a cinema Non-linear content offers user interactivity to control progress as used with a computer game or used in self-paced computer based Non-linear content is also known as hypermedia Multimedia presentations can be live or A recorded presentation may allow interactivity via a navigation A live multimedia presentation may allow interactivity via interaction with the presenter or FeaturesMultimedia presentations may be viewed in person on stage, projected, transmitted, or played locally with a media A broadcast may be a live or recorded multimedia Broadcasts and recordings can be either analog or digital electronic media Digital online multimedia may be downloaded or Streaming multimedia may be

The various formats of technological or digital multimedia may be intended to enhance the users experience, for example to make it easier and faster to convey Or in entertainment or art, to transcend everyday Enhanced levels of interactivity are made possible by combining multiple forms of media Online multimedia is increasingly becoming object-oriented and data-driven, enabling applications with collaborative end-user innovation and personalization on multiple forms of content over Examples of these range from multiple forms of content on web sites like photo galleries with both images (pictures) and title (text) user-updated, to simulations whose co-efficients, events, illustrations, animations or videos are modifiable, allowing the multimedia "experience" to be altered without In addition to seeing and hearing, Haptic technology enables virtual objects to be Emerging technology involving illusions of taste and smell may also enhance the multimedia TerminologyHistory of the 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 The term "multimedia" is also Static content (such as a paper book) may be considered multimedia if it contains both pictures and text or may be considered interactive if the user interacts by turning 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 of research have evolved ( Cognitive load, Multimedia learning, and the list goes on) The possibilities for learning and instruction are nearly EngineeringSoftware engineers may use multimedia in Computer Simulations for anything from entertainment to training such as military or industrial Multimedia for software interfaces are often done as a collaboration between creative professionals and software IndustryIn the Industrial sector, multimedia is used as a way to help present information to shareholders, superiors and Multimedia is also helpful for providing employee training, advertising and selling products all over the world via virtually unlimited web-based Mathematical and Scientific ResearchIn Mathematical and Scientific Research, multimedia are mainly used for modelling and For example, a scientist can look at a molecular model of a particular substance and manipulate it to arrive at a new Representative research can be found in journals such as the Journal of MMedicineIn Medicine, doctors can get trained by looking at a virtual surgery or they can simulate how the human body is affected by diseases spread by viruses and bacteria and then develop techniques to prevent MiscellaneousIn Europe, the reference organization for Multimedia industry is the European Multimedia Associations Convention (EMMAC)An observatory for jobs in the multimedia industry provides surveys and analysis about multimedia and ITC [1]Structuring information in a multimedia formMultimedia represents the convergence of text, pictures, video and sound into a single The power of multimedia and the Internet lies in the way in which information is Multimedia and the Internet require a completely new approach to The style of writing that is appropriate for the 'on-line world' is highly optimized and designed to be able to be quickly scanned by A good site must be made with a specific purpose in mind and a site with good interactivity and new technology can also be useful for attracting The site must be attractive and innovative in its design, function in terms of its purpose, easy to navigate, frequently updated and fast to When users view a page, they can only view one page at a As a result, multimedia users must create a ‘mental model of information structure’Patrick Lynch, author of the Yale University Web Style Manual, states that users need predictability and structure, with clear functional and graphical continuity between the various components and subsections of the multimedia In this way, the home page of any multimedia production 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 (for example, animated GIF on the Web) produces multimedia, but it has typically meant one of the following: Text and sound Text, sound, and still or animated graphic images Text, sound, and video

video Multimedia can arguably be distinguished from traditional motion pictures or movies both by the scale of the production (multimedia is usually smaller and less expensive) and by the possibility of audience interactivity or involvement (in which case, it is usually called interactive multimedia) Interactive elements can include: voice command, mouse manipulation, text entry, touch screen, video capture of the user, or live participation (in live presentations) Multimedia tends to imply sophistication (and relatively more expense) in both production and presentation than simple text-and- Multimedia presentations are possible in many contexts, including the Web, CD-ROMs, and live A rule-of-thumb for the minimum development cost of a packaged multimedia production with video for commercial presentation (as at trade shows) is: $1,000 a minute of presentation Since any Web site can be viewed as a multimedia presentation, however, any tool that helps develop a site in

一)研究内容 ⑴常规媒体在培养和发展学生审美能力方面有哪些不足? ⑵电教媒体在培养和发展学生审美能力方面有哪些优势?课题组将从内容到形式,从方法到效果等诸方面进行深入剖析。 ⑶审美能力包括哪些要素?如何运用电教媒体培养和发展学生审美能力? (二)研究方法 1、文献研究:利用图书馆、资料室及互联网查找相关的研究文献,了解前人在这一课题上有哪些最新的研究成果,积累相关的研究资料,掌握国内外对此课题的研究动态。 2、调查研究:通过调查法、观察法了解学生美学知识、审美能力的现状,进一步明确课题研究的重点和方向。 3、实验研究:以语文学科的课堂教育教学活动为主阵地,同时采用举行课外阅读欣赏活动、召开主题班会、组织论辩、进行参观以及环境渗透等形式,发动师生广泛参与,充分发挥主观能动性和创造性,不断提高学生的审美能力。 三、研究的实施 为了提高研究成员的理论修养和科研能力,我们确定了课题组的学习计划,要求每个成员每学期都要学习一本理论专著,并作好读书笔记;省、市电教馆组织的现代教育技术培训和观摩活动,我们都及时安排课题组成员参加。 三年来,我们着重在课堂教学和课外活动两方面对课题进行了深入的研究和有益的探讨。每学期都有电教研究课,有时还面向全区举行电教观摩课。 为确保每次研究课均能收到实效,课题组经过研讨,在教学中逐渐形成了"电教研究课操作程序",对课前设计和课后反思的内容作了明确的规定: (一)课前思考:1、本课适宜采用哪些媒体?你为何选择此种媒体?2、你准备在何时运用媒体?为何选择此时使用?3、你期望通过媒体的使用达到什么目的?同时发展学生的何种能力?4、你准备用何种方法进行效果检测?5、本课结束后,你要收集哪些资料? (二)课后分析:1、你选择的媒体是否恰当,有没有更好的选择?2、媒体运用的时机是否恰当,有没有更好的时机?3、本课的教学目的是否达到?你所期望的学生能力有否发展?为什么?4、你使用的检测手段是否有效?有什么需要改进的地方?5、你收集的资料能从哪些方面佐证课题?6、本研究课对课题研究有哪些贡献(包括经验和教训)? 课题组成员上电教实验课都必须对照操作程序认真进行教学设计,使以后的研究课不再偏离研究方向,为最大限度地取得实验成效奠定了坚实的基础。 此外,在举行文学作品欣赏、组织辩论对抗赛、召开主题班会等方面,我们也进行了许多有益的尝试,收到了很好的效果。 四、研究的成果 在近三年的课题研究实践中,我们逐渐认识到:审美能力,包括唤醒审美意识的对美的感知能力、形成审美情境的对美的欣赏能力、调动审美经验的对美的鉴别能力和丰富审美心灵的对美的创造能力。这四种能力涉及对美的体验、理解、判断、升华四个层面,落实到每节研究课上,就应各有侧重,或感知美,或欣赏美,或鉴别美,或创造美,或相互融合。为此,我们运用电教媒体,利用语文课及各种相关的活动进行了深入的研究和积极的探索。实践证明:电教媒体的运用,对培养和发展学生的审美能力具有十分积极的作用。 (一)运用电教媒体唤醒审美意识,提高对美的感知能力 审美教育要给学生以丰富的美感。语文教材中蕴含着丰富的美育资源,但对于阅历尚浅的中学生,有时用传统的教学手段和方法,很难使他们真正领悟到这种美,运用电教手段,可以将文字内容诉诸于视觉画面,再配上音乐和有表情的朗读,则可唤醒学生的审美意识,提高对美的感知能力。 在讲授冰心的散文《小橘灯》时,学生对作者为何将小橘灯作为小姑娘的化身难以理解。冰心逝世以后,恰逢中央电视台播放一组根据冰心作品拍摄的电视散文,其中就有《小橘灯》。课题组立即安排实验班学生举行冰心散文赏析活动。当学生以多媒体的方式重温这篇散文时,沉睡的审美意识立即被激活,他们不仅深刻地把握了作品的内涵,而且更真切地感悟到冰心散文的韵美、景美和情美。一位学生写到?quot;真想不到'小橘灯'在画面中的形象那样逼真,那么美好。在阴沉黑暗的背景烘托下,小橘灯闪烁着的朦胧、橘红的光,正是镇定、勇敢、乐观的小姑娘的化身,是小姑娘心灵中露出的最灿烂的火花。它使人看到光明,受到鼓舞。"如果没有电教媒体的介入,没有多种媒体的有机整合,就很难想象学生会有如此深刻的理解。 在教《听潮》一文时,课题组一位老师剪辑了"海睡"与"海醒"两组媒体资料,配上相应的音乐,让学生通过眼看、耳听、心想去感受大海的柔美和壮美,收到了很好的效果。 (二)运用电教媒体创设审美情境,提高对美的欣赏能力 电教媒体在教育中的最大优势就是能集声、文、画于一体,以直观鲜明的图像,生动精炼的语言,极富感染力的音乐创设一种审美情境,使学生深深地被吸引、被感动,在潜移默化中接受美的熏陶,提高对美的欣赏能力。 在"三·八"国际妇女节前夕,我们精心策划了以《献给母亲的歌》为主题的班会活动。整个活动以三首"MTV"为主线:一曲《烛光里的妈妈》拉开了主题班会的序幕,伴随那优美的旋律,屏幕上那位母亲"倦得不再挺拔的腰身,失去光华的眼睛",一下子吸引了同学们的注意力,营造了很好的教育情境。随着《世上只有妈妈好》的乐曲轻轻响起,屏幕上母子情深的形象展现,同学们的情绪受到感染,联想受到激发,纷纷上台,讲述自己母亲的动人故事:有的学生在失去父爱后,母亲含辛茹苦独自挑起抚养儿子的重担;有的学生的继母无微不至关心女儿,继母胜生母……;主题班会上,同学们还用丰富多彩的文艺节目------小合唱、小品、配乐诗朗诵等,回报母亲的恩情,并准备了一份小小的礼物,亲手为母亲戴上美丽的发夹、别致的胸针,献上精心制作的节日卡片,并在写有"以优异成绩回报伟大母亲"的粉红布幅上签名,表达报效之志,爱母之情达到高潮。

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。
