Anytime a teacher wants to use Twitter, Voicethread, whatever the tool, bring them in (if you can), record a video, communicate somehow, the answers to these 3 questions: What are you using? Again, it sounds simple but you've got to communicate what tool you are using. How it works. Are the parents going to have access to the student work? What will they be able to see? This is all the technical stuff. The depth to which you go is up to you. If you can bring them, take the time to teach them how to use the program. Why are you using it? You've got to communicate to the parents the purpose of the use of the tool. How does it fit with the content? Explaining why you are going to use it will help you determine for yourself, the best pedagogy for the technology and how it will fit into your teaching. That, in turn, helps the parents to understand the same. How does the use of this tool enhance student learning? The most important question to answer. How will the use of this ultimately make learning better. Why will the use of this tool be good for kids? You've got to build those bridges with parents. The easiest way is to bring them in and tell them whats going on. Better yet, let the kids teach their parents.

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.

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.

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

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.
