对媒体的定义，目前一般认为是信息储存、传播、表现的载体，也称媒介或媒质。由此可以把媒体分类为：感觉媒体、表示媒体、显示媒体、存储媒体和传播媒体。随着科学技术的发展，媒体的分类在扩展。可以说，媒体是科学技术进步的产物。
教育的发展离不开科学技术的支持。在教学上媒体用于传递以教学为目的的信息，通常称作教学媒体。媒体对教育的影响非常大，越来越多的教育工作者认识到，以网络和多媒体技术为代表的信息技术的发展正在带来整个教育思想、模式和方法的深刻革命。
首先，媒体作为学习的对象，使学生掌握信息技术的知识和技能，使他们能适应现代社会中的学习、工作和生活方式。
第二，媒体可以辅助传统教育。媒体将信息技术与各科课程融合，把各种实用的信息引入课堂，增强学习效果。
第三，媒体帮助构建新型的学习模式。它能够创造新的学习环境和教育环境，以此来探讨新的学习模式。
第四，媒体促进了教学改革。主要是促进了教育目标、内容、模式、组织形式的改革。 媒体的发展，标志着信息时代的多媒体网络技术在学校中的应用，为教育革新创造了前所未有的新局面。
翻译：Application of media in education
About definition of media,it is generally considered to be the carrier of information storage, transmission, performance, also known as medium or medium. So the media can be classified as: feeling media, expression media, display media, storage media and communication media.With the development of science and technology, the classification of the media is in the expansion. It can be said that the media is the product of scientific and technological progress.
Education can not develop without the support of science and technology.In teaching activities,media is used to transmit information for teaching purpose so that it usually referred to as instructional media.The impact of media on education are very large and more and more educators recognize that development of the media are bringing about a profound reform of the educational thought, patterns and methods.
First,media as a learning object,it helps students to master knowledge and skills of the IT and helps them to adapt to the study, the work and the lifestyle of modern society.
Second, the media can complement traditional education.It integrates information technology and curriculum. It introduce a variety of information in the classroom, and enhance the learning effect.
Third，media help us to build a new mode of learning.It can create new learning environment and educational environment in order to explore new modes of learning
Fourth,media promotes the teaching reform.It is mainly to promote the educational objectives, content, pattern, form of organization reform.
Media’s development marks the application of multimedia network technology for the information age in the school.And it create a new situation for Educational Innovation. 传播过程：
在教育中，传播过程是一个由教育者借助教育媒体向受教育者传递与交换教育信息的过程。传播主要要素有教育者、教育信息、受教育者、媒体和通道、传播环境。
其过程分为六个阶段： （1）确定教育传播信息 （2）选择教育传播媒体 （3）通道传送 （4）接收与解释 （5）评价与反馈 （6）调整再传送。 翻译：
In education，process of communication is a process that educatorstransmission and exchange of educational information to educated with With educational media.Its main elements areeducators,education Information,educated,Media and channels, communication environment. The process is divided into six phases：
Determine information ofeducational communication; Select media of educational communication； Transmissionthrough the channel； Receive and Explanation； Evaluation and Feedback； Adjustment and Re-transmission； 教学设计模式：
教学设计模式是在教学设计的实践当中逐渐形成的一套程序化的步骤,其实质是说明做什么,怎样去做,而不是为什么要这样做。
最流行的教学模式可能是ADDIE 模型，该模型包括: 分析（Analysis） - 分析学习者特征和学习任务； 设计（Design） - 确定学习目标，选择教学途径 开发（Development） - 准备教学或训练材料 执行（Implementation） - 讲授或分配教学材料 评估（Evaluation）- 确信达到预定目标
Instructional Design (also called Instructional Systems Design (ISD))is the practice of creating \"instructional experiences which make the acquisition of knowledge and skill more efficient, effective, and appealing.”
Perhaps the most common model used for creating instructional materials is the ADDIE Model. This acronym stands for the 5 phases contained in the model (Analyze, Design, Develop, Implement, and Evaluate).
戴尔的经验之塔：
Tower of experienceis a theory proposed by Dale. It think that human get knowledge mainly by two ways，what are by own direct experience and Indirect experience. It divideslearning experience into three types of ten levelsaccording to the different level of abstraction.As follows,
语言符号（Language symbols） 视觉符号（Visual symbols）
录音、广播、幻灯、照片（sound recording、Broadcasting、Slide、Photo） 电影、电视（Film, television） 参观展览（Visit the exhibition） 见习旅行（Trainee ，Travel）
观摩示范（Observation, demonstration） 参与活动（Participate in activities）
设计经验（理解）Experience in the design（Understanding）
有目的的直接经验（做）direct experiencefor the purpose（do something） 抽象的经验Abstract experience 观察的经验Observation experience 做的经验The experience of doing things
虚拟现实：
Virtual reality (VR) is a term that applies to computer-simulated environments that can simulate physical presence in places in the real world, as well as in imaginary worlds. Most current virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special stereoscopic displays, but some simulations include additional sensory information,
such as sound through speakers or headphones.
Virtual reality is often used to describe a wide variety of applications commonly associated with immersive, highly visual, 3D environments.
