Being told that a bunch of people are addicted is not all that helpful. Even worse is equating lots of time in and of itself to addiction. Why are they addicted? All for the same reasons? What else is going in their lives and cultures? What skills are they picking up if any? Is their massive time-on-task leading to anything or not? What percentage of players are addicted in any harmful sense?

There is also an important issue missed by the show and that is the question of how people from different social and economic groups use and benefit (or not) from digital media. I guess it is not surprising that American TV does not much deal with class issues, but there is little doubt that digital media are leveraged by some families to great benefit for their children in school as part of a larger learning and literacy ecology that includes digital media and print. Other families use digital media in quite different ways. Indeed, there are many different uses with many different outcomes--my simple dichotomy really will not do, but it raises the issue of equity and outcomes for diverse people in our society (and, indeed, world).

Books can make people smarter or dumber--they can expose them to the world or hide reality from them. So any real understanding of them would have to be nuanced and contextual. For books we have long learned to ignore their power for bad. For digital media we are predisposed--at least if we are Baby Boomers--to look for the dangers.

The film is indeed thought provoking. Its power is in being by and large an "etic" (outside) view of other people's new cultures. It is less good at giving a real feel for what those new cultures and their concomitant practices mean to young people today from the inside.

What works for me about the website is that it is multi-vocal, allowing many points of view to be expressed on more or less equal footing, encouraging reflection as people make their own decisions about what to watch and how to juxtapose the pieces. I doubt any two readers took the same path through this material or any two teachers used the resources the website provides in precisely the same ways.

I frankly found the documentary itself mind-numbing and relentless. It rarely trusts the viewer to draw their own conclusions about what they are seeing and it deploys much of the material in ways which point towards a much less nuanced conclusion than any of the participants in the conversation might have advocated.

students need to be able to highlight important passages, make notes in the margins of the text, and quickly skim through passages to refresh and compare information. In all three pilots, the students felt that e-readers were not yet ready to meet these academic needs.

the Kindle’s small keyboard makes the annotation process very labor-intensive

Because the keyboard is so small, and because there was a significant latency between typing the note and the note appearing on screen, a lot of students found that they were overtyping. Many of the students got fed up with the keyboard, so they would just read on their Kindle and make notes in a separate notebook.” Also, the Kindle allows readers to make annotations only in e-book-format files, meaning that students couldn’t insert notes on any PDF-format files that were on the devices. “I think the first [e-reader] manufacturer that figures out how to make a PDF that you can also annotate is going to snag this market,” Temos predicts.

He is hesitant, though, to say that this problem is primarily because of a deficiency in the device, when it could just as easily be that the students need to adapt to using a new technology. “[ASU is] going to look at whether this is something that students get used to in the second semester of the pilot and eventually prefer, or if it remains consistent that they continue to prefer paper,” he says. “I think we don’t know that yet.”

Highlighting text with the Kindle was not much easier or more satisfying for Princeton students. Much of the difficulty was due to the inability to highlight in color on the grayscale E Ink screen. “The highlighting on the Kindle isn’t actually highlighting; it just makes an underline,” Temos explains. “The students want something more emphatic than that.” Students also found it awkward to highlight long passages using the trackball. “Highlighting over a page break on the Kindle is a real feat,” Temos laughs. “If you actually extend your highlight from one page to the next you feel a real sense of accomplishment.”

At Reed College, having all the texts available in a political-science class on the iPad meant it was easier to refer to readings and pull in outside material for discussion, says Martin Ringle, the college's chief technology officer.

Course readings were converted to PDF's at Reed, which allowed students to mark them up using an application called iAnnotate, but Mr. Ringle acknowledges that this wouldn't work for all classes, because many texts can't easily be converted to PDF's, and many electronic textbooks don't allow annotation.

While Apple has promoted the iPad's ability to change learning, Ms. Simon says that as far as she knows, the company isn't working with leaders in the learning process: professors themselves.

but consumer decisions rather than educational ones will probably determine which tablets students purchase—and which ones colleges will support, he says.

The level of perceived challenge The type of rewards or recognition available The context or content used for practicing and assessing skills The tools used for information gathering or production The color, design, or graphics of layouts, etc. The sequence or timing for completion of subcomponents of tasks

it is important to build in periodic or persistent “reminders” of both the goal and its value in order for them to sustain effort and concentration in the face of distracters.

Prompt or require learners to explicitly formulate or restate goal Display the goal in multiple ways Encourage division of long-term goals into short-term objectives Demonstrate the use of hand-held or computer-based scheduling tools Use prompts or scaffolds for visualizing desired outcome  Engage learners in assessment discussions of what constitutes excellence and generate relevant examples that connect to their cultural background and interests 

Mastery-oriented feedback is the type of feedback that guides learners toward mastery rather than a fixed notion of performance or compliance.

Provide feedback that is frequent, timely, and specific Provide feedback that is substantive and informative rather than comparative or competitive

So schools do not teach effective use of Google, of text-messaging, of instant-messaging. They don't teach collaboration. They barely teach communication outside the stilted prose only academics use. No wonder students are prepared for nothing except more school.

There is also the issue of educational discrimination. When schools fight against technology, they are fighting access to education for people who learn and function differently. Technology, from computers to calculators to classroom cellphones, enables a wide variety of students who would otherwise be left out to participate and succeed. Technology in the hands of all students allows disabilities and functional deficits to be invisibly accommodated so that knowledge can be developed, nurtured, and evaluated on terms fair to everyone.So, no, the problem is not cheating. The problem is firmly one of instructional and evaluation technique. It will not be solved until teachers and professors figure out that understanding and the ability to work with knowledge is what counts, and that anything you can instantly Google, or store in your calculator, or retrieve via quick text-message or phone call need not be remembered, nor tested, because, obviously, you will always be able to instantly Google it, or store it in your cellphone, or get someone to text it to you. 

It would be interesting to pull the data in from previous decades and see how the elevation has changed in different areas.

@adrian – it’s just raw totals, grouped geographically. These aren’t scientific by any means, I basically took the underlying pattern and extruded it out and smoothed it a bit to make it look “pretty”. But basically each image is the aggregate numbers for a single year of crime data.

@richard – yes, there is some smoothing in effect, which means that the ridge along Shotwell St (for the prostitution map) is indeed a bit smoothed between peaks. That’s not to say that there are only two peaks at Shotwell and 19th and Shotwell and 17th. There are incidents in between as well, but the big peaks at those major intersections does mean that the ridge between them appears higher than the actual incidents along those blocks support. A lot of people have commented on the usefulness of maps like these. I want to stress once again: this was done as an art project much more than a useful visualization. My goal was not to provide useful information that one could act on.

“one trick pony. these maps add nothing of value to a standard color plot.” I disagree: allowing for a third dimension of elevation makes the reality of concentration clearer – and half the point of crime mapping is to measure concentration, not simply “intensity.”

Great idea and nice work on the graphics, but there are at least three improvements you should make to reveal *true* patterns. Forgive me if you already did these. 1) Availability bias – normalize for population density (i.e. per capita activity) 2) Sampling bias – normalize for the number of cops on the beat (geographic and crime type) 2) Frame bias – break it up by daytime and night time
