Teaching With Technology in the Information Age

VOICE ONE:
In our first two programs we discussed the history and importance of communicating information. We talked about the development of the Internet. This has made it possible for almost anyone with a computer to share in what is called the Information Age.
Research shows that the Internet's World Wide Web is especially popular with young people. As a result, colleges and universities are recognizing the learning gains that can be made with Web-based instructional technology. For example, George Mason University in Fairfax, Virginia offers its professors training in instructional technology. G.M.U. teachers can learn how to use the latest Web tools to improve their classes.
VOICE TWO:
Podcasting is also a very popular instructional technology. The term was invented with the Apple company's iPod in mind. IPods are small digital audio players that permit users to download music from their computer directly to the device for listening later.
The term podcasting no longer relates only to the iPod. It involves any software and hardware combination that permits the user to download audio files and control when those files are heard. Anyone with a modern computer can create, make available and download a podcast from the Internet.
VOICE TWO:
Podcasting also makes education transportable. Teachers can make their talks, or lectures, available to students who miss the class. Podcasts also let students hear what other experts have to say. Remember that biology teacher who asked her students to bookmark Web sites about flowers and plants? She might also ask her students to report about that collection of resources in a podcast.
Rick Reo says George Mason is one of many "iTunes universities" around the world. Apple has opened its iTunes store to universities. Podcasts created by the schools are stored on Apple's computer servers. Anyone can download the free educational material at Apple's iTunes store. Stanford, Yale, Duke, and the Massachusetts Institute of Technology are other universities offering audio and video downloads.
VOICE ONE:
Podcasts are fed to computers using a technology called RSS. Many creators of information on the Internet offer it directly to people using RSS feeds. Our biology teacher example might ask her students to register for RSS feeds from five popular science Web sites. To receive those feeds, students need to register for a free RSS reader, or aggregator. Google and MyYahoo both offer RSS readers.
Once the students register for a free RSS reader, a connection has to be made between the reader and the student's favorite science Web sites. Establishing these connections is called subscribing. It is easy to do. Just look for an RSS sign on the site.
Using RSS technology helps people easily get new material from Web sites that interest them. Did you know that Special English offers RSS feeds? You can find a link to RSS on our Web site, 51voa.com.
VOICE TWO:
Wikis have also become a popular Web 2.0 technology in education. Let us go back to our biology class. Suppose the teacher decided to take her class on a camping trip to collect plants and flowers. The students would need to work collectively to decide what to bring on the trip. A wiki can help. A wiki is a Web site where anyone can create, edit or change information collected on the site. Audio, video and pictures can be added to a wiki as well.
VOICE ONE:
The most popular wiki on the Internet is Wikipedia. It is a free encyclopedia of information about people, places, things, events and ideas that anyone can write, add to or edit. Wikipedia was launched in two thousand one. Today, it includes more than ten million articles in more than two hundred fifty languages. More than two million articles are in English. Each article offers links to other Wikipedia articles or to other Web resources.
Educause reports that Wikipedia is the eighth most visited Web site in the United States. College students use it as a main research tool. However many schools look at the tool with a critical eye. That is because a person can put incorrect information on Wikipedia. The history school at Middlebury College, for example, has banned Wikipedia in student research. The ban was ordered after several students repeated the same wrong information from a Wikipedia article.
Other universities are using Wikipedia to teach students how to write without expressing an opinion. At Columbia University in New York City, professors have had their students create or edit Wikipedia articles to learn how to write in a neutral way.
VOICE TWO:
Perhaps the best known form of Web 2.0 activity is the Web log, or blog for short. There are reportedly more than one hundred million blogs around the world. A blog is an online collection of personal comments and links to other Web sites. Anyone can create a blog using sites like blogger.com or wordpress.com. Bloggers often work together in small communities. They read each other's posts, link to them or report what other bloggers say.
Each individual post on a blog can become a discussion through comments left by readers. There are personal blogs, political blogs and entertainment blogs, just to name a few. In higher education, professors use blogs to communicate their opinions or to create a discussion with other educators. Students are also using blogs for personal expression or as part of their classes.
VOICE ONE:
There are many other ways that information technology can be used in education. We have only reported about a few of them. For example, there are virtual worlds and gaming, Web-based self-publishing and photo-sharing. When it comes to information technology in higher education, Rick Reo at George Mason University says the sky is the limit.
