Rotstein, Arthur H. Books Are Out, iBooks Are In for Students at Arizona High School. St. Louis Post-Dispatch 19 Aug. 2005: C2. Print.The following is excerpted from an article in a local newspaper.

Students at Empire High School here started class this year with no textbooks but it wasnt because of a funding crisis. Instead, the school issued iBooks laptop computers by Apple Computer Inc. to each of its 340 students, becoming one of the first U.S. public schools to shun printed textbooks. School officials believe the electronic materials will get students more engaged in learning. Empire High, which opened this year, was designed specifically to have a textbook-free environment. Weve always been pretty aggressive in use of technology and we have a history of taking risks, said Calvin Baker, superintendent of the Vail Unified School District, with 7,000 students near Tucson. Schools typically overlay computers onto their instruction like frosting on the cake, Baker said. We decided that the real opportunity was to make the laptops the key ingredient of the cake . . . to truly change the way that schools operated. Used with permission of The Associated Press.

Delaney, Kevin J. Teaching Tools. Wall Street Journal17 Jan. 2005: R4. Print. The following is excerpted from an article in a national newspaper.

Pioneering teachers are getting their classes to post writing assignments online so other students can easily read and critique them. Theyre letting kids practice foreign languages in electronic forums instead of pen-and-paper journals. Theyre passing out PDAs to use in scientific experiments and infrared gadgets that let students answer questions in class with the touch of a button. And in the process, the educators are beginning to interact with students, parents and each other in ways they never have before. The issue is, how do we communicate with students today who have grown up with technology from the beginning? says Tim Wilson, a technology-integration specialist at Hopkins High School in Minnetonka, Minn.

Dyson, Esther. Untitled essay. What We Believe But We Cannot Prove: Todays Leading Thinkers on Science in the Age of Certainty. Ed. John Brockman. New York: Harper, 2006. 192-194. Print. The following is excerpted from a book about science and technology.

Were living longer and thinking shorter. Its all about time. Modern life has fundamentally and paradoxically changed our sense of time. Even as we live longer, we seem to think shorter. Is it because we cram more into each hour, or because the next person over seems to cram more into each hour? For a variety of reasons, everything is happening much faster, and more things are happening. Change is a constant. It used to be that machines automated work, giving us more time to do other things, but now machines automate the production of attention-consuming information, which takes our time. For example, if one person sends the same e-mail message to ten people, then ten people (in theory) should give it their attention. And thats a low-end example. The physical friction of everyday life the time it took Isaac Newton to travel by coach from London to Cambridge, the dead spots of walking to work (no iPod), the darkness that kept us from reading has disappeared, making every minute not used productively into an opportunity lost. And finally, we can measure more, over smaller chunks of time. From airline miles to calories (and carbs and fat grams), from friends on Friendster to steps on a pedometer, from real-time stock prices to millions of burgers consumed, we count things by the minute and the second. Unfortunately, this carries over into how we think and plan: Businesses focus on short-term results; politicians focus on elections; school systems focus on test results; most of us focus on the weather rather than on the climate. Everyone knows about the big problems, but their behavior focuses on the here and now. How can we reverse this? Its a social problem, but I think it may also herald a mental one which I imagine as a sort of mental diabetes. Most of us grew up reading books (at least occasionally) and playing with noninteractive toys that required us to make up our own stories, dialogue, and behavior for them. But todays children are living in an information-rich, time-compressed environment that often seems to stifle a childs imagination rather than stimulate it. Being fed so much processed information video, audio, images, flashing screens, talking toys, simulated action games is like being fed too much processed, sugar-rich food. It may seriously mess up childrens informational metabolism their ability to process information for themselves. Will they be able to discern cause and effect, put together a coherent story line, think scientifically, read a book with a single argument rather than a set of essays?

First published by Edge (www.edge.org).informational metabolism their ability to process information for themselves. Will they be able to discern cause and effect, put together a coherent story line, think scientifically, read a book with a single argument rather than a set of essays? I dont know the answers, but these questions are worth thinking about, for the long term.

Johnson, Steven. Interface Culture: How New Technology Transforms the Way We Create and Communicate. New York: Basic, 1999. Print. The following is an excerpt in which the author reflects on his early experience using a computer.

Fast-forward a decade or two, and I cant imagine writing without a computer. Even jotting down a note with pen and paper feels strained. . . . I have to think about writing, think about it consciously as my hand scratches out the words on the page, think about the act itself. There is none of the easy flow of the word processor, just a kind of drudgery, running against the thick grain of habit. Pen and paper feel profoundly different to me now they have the air of an inferior technology about them, the sort of contraption well suited for jotting down a phone number, but not much beyond that. Writing an entire book by hand strikes me as being a little like filming Citizen Kane with a camcorder. You can make a go at it, of course, but on some fundamental level youve misjudged the appropriate scale of the technology youre using. It sounds appalling, I know, but there it is. Im a typer, not a writer. Even my handwriting is disintegrating, becoming less and less my handwriting, and more the erratic, anonymous scrawl of someone learning to write for the first time. I accept this condition gladly, and at the same time I can recall the predigital years of my childhood, writing stories by hand into loose-leaf notebooks, practicing my cursive strokes and then surveying the loops and descenders, seeing something there that looked like me, my sense of selfhood scrawled onto the page. On a certain level these two mental states are totally incompatible bits versus atoms but the truth is I have no trouble reconciling them. My written self has always fed back powerfully into my normal, walking-around-doing-more-or-less-nothing self. When I was young that circuit was completed by tools of ink and paper; today it belongs to the zeros and ones. The basic shape of the circuit is unchanged.
