20th Century Learning vs 21st Century Learning
Web 1.0 vs. Web 2.0
Web 2.0 websites allow users to do more than just retrieve information. They can build on the interactive facilities of "Web 1.0" to provide "Network as platform" computing, allowing users to run software-applications entirely through a browser. Users can own the data on a Web 2.0 site and exercise control over that data. These sites may have an "Architecture of participation" that encourages users to add value to the application as they use it. This stands in contrast to very old traditional websites, the sort which limited visitors to viewing and whose content only the site's owner could modify. Web 2.0 sites often feature a rich, user-friendly interface based on Ajax, Flex or similar rich media. The sites may also have social-networking aspects.
So what is Web 2.0? Here are six elements that define the change in how we all think about and use the Web:
- Web 2.0 is about data abstraction. All those Web 2.0 functions people love to talk about, such as tagging, sharing, XML, open APIs (define), and mashups, only became possible because we now understand how to free information from containers. Though the Web credo "information wants to be free" has been around for a while, we've only recently been able to make it happen. Pulling information out of proprietary containers allows you to do pretty much whatever you want with it, whether driving collaborative sites, interfacing with mobile devices, or something else.
- Web 2.0 takes broadband and Moore's Law for granted. Sites like YouTube and Google Docs & Spreadsheets wouldn't be possible in a non-broadband world populated by powerful computers. All Web 2.0's multimedia features, especially video, start with the assumption bandwidth is basically free and readily accessible.
- Web 2.0 is about connections. Connections between people, between sites, between the Web and mobile worlds, between buyers and sellers. Web 2.0 includes all of them. At its heart, the new Web is about moving from a one-to-many publishing model to a many-to-many one.
- The Web 2.0 revolution puts people first. All the tagging, social content, social networking, blogging, and virtual communities people point to as examples of Web 2.0 come out of this. It's perhaps the most widely recognized aspect of what's changing. But putting people first is more than just connecting them or allowing them to post content. It's also understanding people use the Web. The needs of the user (not the programmer, marketing director, or information architect) come first.
- Web 2.0 is about allowing people to manipulate data, not just retrieve data. The AJAX revolution isn't that it lets you make zippy interfaces that kind of look like real desktop applications in a browser. It's that it does away with the old Web 1.0 model of request page/get page/view page technology all of us were used to. Contrast the old MapQuest "point and zoom and pan with buttons" interface with the revolutionary interface Google Maps deploys. All of a sudden, we're actually in there with the data, moving it around, playing with it, and interacting with it in real time.
- Web 2.0 is about doing stuff on the Web that can't done in any other medium. Functionalities that have generated so much Web 2.0 hype are all things that wouldn't be possible without the Internet. Period. Much of Web 1.0 tried to shoehorn old media models into the new technology, often with bad or even disastrous results. All the bad thinking of the past decade or so revolved around the misperception that the Web is "like medium X, only different." The Web isn't TV with clicking. It isn't print with the ability to link and embed multimedia content. Podcasting isn't radio you can download.
You get the idea. To truly do Web 2.0, you must do something that absolutely can not be done without the Web.
It's as simple as that. (from Sean Carton
