增强实境(技术)也被称作增强现实如何能改变教学( How Augmented Reality Can Change Teaching--Ken Myers 2012),增强实境背后的技术将现实世界的景象透过计算机生成映像,这个过程无论是透过计算机的显示器或者透过照相机、镜头实现转动眼球成像,增强实境的做法拥有完成重大挑战任务的学习潜力。各类教育工作者都在实施这种技术,并已取得了积极的进展和最佳的效果。学生使用该技术聚焦学习任务,变得更加专心致志。
1.在增强实境的学习环境中,学习者对三维物体(3D)的观察可以通过个人之间的互动交流活动去恳请和改变认识的角度。从计算方块的初步数学到从各角度去欣赏艺术品,学生通过技术可以学习过程变得更加着迷。
2.引发的学习效应。尽管互动学习项目没有什么新意,但是可视化的学习变化在真实生活中有魅力。学生通过学习项目指令的操作可以将他们面前的物体产生变化。
3.人工智能(AI)通过增强实境的物体进行过学习实验。你是否能想象出学生在倾听林肯本人在葛底斯堡现场的演说感受会有什么影响?人工智能在实验项目中能与现实世界的场景对接得上。
4.重新展示-使用卡片作用作为增强实境学习的一部分技术,学生可以观察物体的重新展示过程。其余的卡片可用于获得有关物体的信息并可通过显示器或转动的镜头展示给学生看。比如能通过三维映像给学生观察一个水的化学分子,认识水分子的形成过程。
5.阅读-对孩子来说互动活动对他们的学习有强大的影响。当你的孩子利用增强实境的技术使用立体书的时候,它将吸引学生的注意力吗?视觉和声音是让学生感知真实世界动物的一个好的方法。阅读中提高语境氛围。一本关于火车的书,阅读中可以让学生感受到读者仿佛站在火车站的站台上。
6.古代文明。比如没有古文物展览,要一位教授教学古代文明知识,增强实境技术可以给他他们带去文物展览,无论是个体学生要从每个角度去检验文物或工艺品,或教授要通过投影展示工艺品给大家看,能提高手头上现有的教学方法。
7.切割或解剖-如人体检查,增强实境给大家提供了逐一去除人体器官表层的观察实境。当然这个技术也可以用于素描课,如将某一建筑的表层移除,展示给学生看,将给学生看到建筑的重要框架。
8.空间-当提供具体名称的时候,通过智能手机和平板电脑应用程序能让你看见天空和分布的星座。无论如何它对教育的价值有多大,它能将附有统计数据的信息使行星和星球拉近对他们的心理空间距离吗?
9.地标-应用程序利用当地的GPS可以再次向你提供历史性的地标信息进行可视化阅读。采用增强现实的技术,地球表面的地标或雕像可以在你的屏幕显示器上复活,并向你讲述它的真实故事。
10.鲜活的教科书-在阅读方面取得了上述的进展,如果再更进一步的话,增强实境能给教科书展示更多的真实性给读者。
全景展现增强实境的技术有无穷的可能性,学生能通过计算机映像去改变一个类似真实的世界。这个形象比喻可以将事物虚拟化、程序化。三维映像通过增强实境技术给大家一种强大的能力可从任意角度去检验它。我们将其他技术未来发展中应用增强实境技术的前景抱有浓厚的兴趣并拭目以待。

The technology behind Augmented Reality is taking a real-world view and enhancing it with computer-generated imagery. Whether this is done by using a computer monitor and camera or fitted goggles to imprint imagery in the lenses, augmenting in this manner has great possibilities for a variety of tasks.Educators of all kinds are implementing this technology and the progress has been nothing short of excellent. Children that use this technology have remained focused on the task and have seemed more attentive to the lesson. How can AR technology impact our educational system for primary and tertiary learning?
1. 3D – Objects viewed in the AR environment have a 3D appeal that can be moved and changed through personal interaction. From counting square blocks for rudimentary math to viewing works of art from every angle, students are entranced by the technology.
2. Cause and Effect – Although interactive educational programs are nothing new, there is something to be said about visualizing changes in real-life. Students can manipulate and change the object in front of them through programmed commands.
3. AI – Artificial intelligence has been experimented on with AR objects. Could you imagine the impact it could have on a student to have a recital of the Gettysburg Address read aloud by Abraham Lincoln himself? The AI for some experimental programs have even been able to react to real-life objects being placed next to them.
4. Representation – Through the use of the cards as part of the AR learning technology, students can observe a realistic representation of the object. Other cards can be used to gather information about the object and display it to the student on the monitor or AR goggles. For instance, students are able to see what a water molecule looks like in 3D and can gather information about how H2O is formed.
5. Reading – For young children, interactivity is a strong influence in learning. How enthralled would your child be using a pop-up book that seemed to really pop up? Sights and sounds can be a method of showing a child what animals sound like in real-life, enhance the background ambiance while reading, and more. A book about trains could engage the reader and make them feel like they were standing at the station.
6. Ancient Civilizations – For a professor trying to teach about ancient civilizations without artifacts to exhibit, AR technology can bring the artifacts to them. Whether it is an individual student examining every angle of the artifact or the professor displaying the artifact on a projector for all to see, the enhancement could bring more of a hands-on approach to teaching.
7. Dissections – Augmented Reality gives us the ability to literally remove layers from a body for a more detailed examination. Of course, this could also work in a drafting class by peeling away the layers of a building to demonstrate to the students why certain framework is important to construction.
8. Space – There are smartphone and tablet apps that will allow you to view the sky and spot stars and constellations while providing their names. However, how much greater of an educational value would they have if they could bring the planet or star closer to them with statistical information?
9. Landmarks – Again, apps utilizing your GPS location can provide your information about the historical landmark you are viewing. With AR technology, that landmark or statue could essentially come to life on your screen and tell you its story first hand.
10. Alive Textbooks – What if we take the reading aspect above and take it a step further. Augmented Reality can give a textbook the means to show examples of the content to the reader for greater clarity.
The full scope of AR technology has endless possibilities. Students are able to affect a seemingly real-world change through the use of computer-generated imagery. This imagery can be programmed for virtually any subject matter. The 3D imagery through AR technologies gives us a greater ability to examine any given object from all angles. It will be interesting to see what other technologies implement AR in the future.
