When my 2nd grader needs to know the meaning of a word, I tell him to use my iPhone to ask Siri, an artificial intelligence program that's always happy to look it up for him. Siri, in turn, uses the free online program Wolfram Alpha, one of the most powerful data analysis tools in the world. If you enter into the Siri (or Wolfram Alpha) search box, by text or voice, "arable land in world divided by world population," in less than a second the phone or computer will find the relevant data; do the calculations; provide the answer—in square miles, acres, square feet, and hectares per person—and cite you its sources.

call the process of envisioning such technically enhanced possibilities imag-u-cation. It's something every teacher and class should spend some time doing.

With YouTube, for example, students can post their ideas to the world and get rapid global feedback. With tools like Twitter and its cousins, they can follow firsthand details of events unfolding anywhere in the world, from revolutions to natural disasters. With mashups and related techniques, they can combine sophisticated data sources in powerful new ways. One school group I know of created a Second Life model of Los Angeles, using the database of the Federal Aviation Administration (FAA) to show each plane flying in its actual spot! With Skype-like tools, students can connect with experts and peers around the world in real time.

Generally, the place where teachers and students get into trouble when it comes to copyrighted music is when anyone is doing something for a COMMERCIAL purpose (like a fundraiser) and using copyrighted content without permission, or when they are RE-PUBLISHING content without permission on the “open web.” (The public Internet, on a website which does not require a login or authentication to access it.)

This is more than just teaching kids how to use computers. Kids already know this. They know how to use computers before they get to school.

People seem to forget this fact, and often these are the same people who are running the society. They would rather spend money on the military than on the educational system, unaware that the military will bring them zippo. It's not a great idea to want to take over the world if you don't know what to do with it and how to run it. Nothing is accomplished through conquest. Everything is accomplished through education.

SizeObjects that are bigger demand more attention. Using size as a hierarchal tool is an effective way of guiding a viewer’s eye to a particular portion of the page. Because size is one of the most powerful forms of organization, it’s important to correlate size with importance in a design. The biggest elements should be the most important in most cases; the smallest elements should be the least important.

. When used as a personality tool, color can extend beyond into more sophisticated types of hierarchy; Using lush, comforting colors can bring an emotional appeal to a page.

Within a page there might be widgets that are separated from each other by space; within those widgets there is a new hierarchy of title, subtitle, and content.
