We talk about what teaching and learning ought to look like, without ever really being clear about what we want an education to do. Pictures have different purposes. Their intent may be to record an event, evoke an emotion, preserve a memory, provide documentation, honor an individual, or just please the eye. A great work of art might do all of those things, but it is unrealistic to expect all art to accomplish all of them. Knowing more about the subject of the work, the mind of the artists, the goals of the person who commissioned the work, and cultural setting in which the work was produced my help us understand more about how to view a work of art. So what exactly is it that we are looking for in public education? Do we value symmetry over emphasis? Are we looking for accuracy or imagination? Should education inspire or indoctrinate? Do we want an education that gives us answers or asks us questions? There are a lot of people critiquing the “art” of educating our children. Is the picture of public education all wrong? Or is it that we don’t always know how to look, or where to stand, or what to look for once we’ve got to where we need to be? I don’t know the answers, but it seems to me that the questions are worth asking.

teacher in suburban Washington DC has launched a collaborative writing initiative using the messaging tool Twitter. Prepare to be concise!

a middle school teacher in Montgomery County, MD, launched Manyvoices, which may be the first collaborative student writing project on Twitter. Mayo’s idea was to embrace Twitter’s 140 character limit as a creative challenge for his students, using a framework known as a Twittory. Created by Cameron Reilly, a Twittory is a story in which each person may add only 140 characters to the story. The story must also be told in 140 posts - no more, no less.

Some Internet experts believe the next generation of the Web -- Web 3.0 -- will make tasks like your search for movies and food faster and easier. Instead of multiple searches, you might type a complex sentence or two in your Web 3.0 browser, and the Web will do the rest. In our example, you could type "I want to see a funny movie and then eat at a good Mexican restaurant. What are my options?" The Web 3.0 browser will analyze your response, search the Internet for all possible answers, and then organize the results for you.

­That's not all. Many of these experts believe that the Web 3.0 browser will act like a personal assistant. As you search the Web, the browser learns what you are interested in. The more you use the Web, the more your browser learns about you and the less specific you'll need to be with your questions. Eventually you might be able to ask your browser open questions like "where should I go for lunch?" Your browser would consult its records of what you like and dislike, take into account your current location and then suggest a list of restaurants.
