Lightning in a Bottle

While I was at the ACPE conference last week I had a chance to work for a few minutes with a CTL 2Go PC (the same device I mentioned a few weeks ago).  It feels much more rugged than the EeePC, and to underscore the point, the company representative repeatedly demonstrated dropping the device from about five feet in the air.  The trade-off is that it is a little larger and heavier than the EeePC, but that also gives you a larger screen and longer battery life.  As the previously-linked review noted, the keyboard is still pretty cramped, and the screen resolution is still only 800×480, despite the larger display.  My major frustration with the keyboard is that the right Shift key is very small, and the Enter key is where I expect the quote/apostrophe key to be,  which causes me to regularly break sentences (or IM messages) when  I try to type I’m or similar words. They’re still pretty amazing, though!

The ustream.tv site we’ve been experimenting with (check and see if I’m online - sorry if I don’t notice when you enter, there’s no sound clue when someone pops in) is being used by a school district in eastern Washington for daily updates and things such as broadcasting band practice. John Kelly from ESD 123 introduced the site to a teacher there, and they have jumped all over it. Check them out, and if they aren’t live watch one or two of their archived sessions!

John Pederson posted a link to a new YouTube video on his TechLearning blog today. It’s a short, interesting piece that explores the nature of sharing in the modern age.

I’ve been a big supporter of having students work with robotics since we taught robot camps at the Pacific Science Center back in the 1980s. I am always enthralled with the complexity and depth of the kids’ learning experiences as they collaborate, invent, design, built, and program their creations. Interest in this area has grown, and over the years their have been several generations of Lego Robotics systems and other classroom robotics curricula. On a much grander scale, the last decade has seen huge growth in the FIRST Robotics and FIRST Lego League after-school programs which have expanded to include tens of thousands of students. (I missed the FIRST competition in Tacoma a few weeks ago - drat!) Still, robotics languishes primarily as an after-school activity available in a few isolated school, and that’s always disappointed me.

In addition to the tremendous educational value I have seen in robotics, however, there is growing value in that area in terms of future careers. As the power of processing continues its relentless march into seeming infinity, we are getting close to a world of robotic devices that would appear to be out of science fiction. A popular video on YouTube lately has been film of a robot called Big Dog, a quadruped walking robot designed to carry military equipment. Another video making the rounds shows a prosthetic arm designed by Dean Kamen’s company that is so lifelike they call it the Luke Arm (as in Luke Skywalker). The military is funding much of the development of this field of study, but the spinoffs will move rapidly into other applications.

And this article describes a prediction just made that 3.5 million jobs will be replaced by robots in Japan by 2025. Not manufacturing jobs, but service jobs like nurses’ aides, receptionists, and so on. The Japanese population is aging rapidly, and there will be fewer and fewer young people to take on these jobs.

So this starts to look like a serious win-win situation to me. Robotics is a phenomenally exciting project-based learning experience for students of a wide variety of learning styles, one that immerses them in a process that thoroughly integrates design, creativity, mechanics, electronics, physics, math, and a host of many other areas - even art! And now, robotics is also a rapidly expanding career opportunity for our students. We need to look for more ways to give kids the chance to explore this fascinating, exciting area of study. (Or we may be importing all of our robots from Japan.)

The new particle accelerator in Europe at the Cern laboratory has been in the news quite a bit the last month or so. This massive device is designed to smash subatomic particles together at tremendous speed to try and uncover new information about the nature of matter, including looking for a conjectured particle called the Higgs boson, the only particle predicted by the Standard Model of Particle Physics that has never been directly observed. (Ok, sorry about all that. I’m a science nerd, after all.)

I mention it here not to revel in arcane science, but because of an interesting technology backstory to this effort. As the Large Hadron Collider, or LHC, was being designed, the researchers realized that the volume of data it would produce was so large that it would potentially overwhelm the Internet when shared with scientists around the world. Their solution was to create a parallel network - that is amazingly fast. In addition to using fiber optics, the researchers designed an entirely new system for managing the transfer of the data. This combination creates a network that is up to 10,000 times faster than the existing Internet.

This technology is currently only available to certain institutions, but it will at some time begin to replace the Internet we currently use. Bandwidth will increase to a level that we literally can’t envision. What will we do with a technology that lets us back up a 120 gigabyte hard drive onto a remote server in five or ten seconds? The article linked above explores some of the conjectures, but the most dependable prediction for what we will do with that much capacity is something we haven’t thought of yet.

I’ve been recently enjoying exploring social networking programs like Twitter and Facebook, and I’ve been a long-time user of instant messaging (MSN Messenger, AOL’s AIM, Yahoo Instant Messenger and Apple’s iChat) as well as web-based email through Yahoo. The problem, however, is keeping track of all of these different possible communications systems without going crazy.

I’ve known there were clients (such as Adium for the Mac) that combine multiple IM services into one interface. However, today I’ve been exploring Digsby, which not only combines IM services, but also social networking applications such as Twitter and Facebook.

Now I have one application that sits on my screen and alerts me if any buddy is online from any of my online accounts, if there have been updates to any of the Twitter users that I follow, updates to my Facebook friends, or new emails to my Yahoo account. It will take a few weeks to see if it really changes my habits long-term, but for now I am finding myself far more likely to use these services because I can do it so much more quickly.

As expected, more devices are coming to market to compete with the Asus EeePC. Laptop Magazine now has a hands-on review of the 2go PC, which is one manufacturer’s version of the Intel Classmate 2 design. It’s fairly rugged to hold up to student use, sports a carry handle, has a 9-inch screen, 30 gigabyte hard drive, webcam, and the option of Linux or Windows XP. Reportedly the Linux version will be $399 and the Windows version $499 at list price.

I can’t wait to see what happens in this market niche over the next 12 months!

I’ve been experimenting with a service called Ustream.tv, and it’s very intriguing. Basically, it’s YouTube for live video broadcasting over the Internet. It took me five minutes to set up an account, and now I can broadcast live video any time I want!

Wesley Fryer used this system last week to broadcast live presentations from the Air and Space Museum in Washington D.C. Using a cellular data modem, a laptop and camcorder, he was able to set up anywhere he could receive a cell signal. And since the broadcasts can be archived, anyone who misses the live broadcasts can view them after the fact.

There are dozens of live broadcasts going on at any one time. Right now some guy is doing music lessons, answering questions of the people logged into the session. (He’s on every day from noon to four Pacific time.)

Of course, there will probably be some channels that have programs that won’t be appropriate for kids, so getting this through to a school network may prove to be a problem. (Not to mention the nonsense that shows up in the chat windows and protecting the bandwidth of the district.) But sooner or later there will school-safe versions and we’ll have enough bandwidth to have this a tool that students can use to share presentations across the world, or participate in presentations of mentors or experts out in the field.

I’ve even set up my own channel! I’ll be hanging out at http://www.ustream.tv/channel/ed-tech-chat off and on during the week of March 17. Drop on by and see if I’m online.

Professor Michael Wesch from from Kansas State University has a great blog post that went up today.  It contains a link that shows a synchronized video/PowerPoint presentation he did at Educause on the “The Crisis of Significance.”  It incorporates some of the material from his videos, but puts it into a context that brings a clarity to those presentations.  It’s about an hour long, and incorporates 379 slides (!), but it effectively underscores a lot of what I’ve been thinking about lately.  We don’t have simply a technology gap with students coming into schools now, we have a cultural gap.  While the “generation gap” has been around for a long time, the impact of technology seems to be creating greater and faster levels of separation in ways that directly impact what and how we teach.

Note - I did have to install a plugin to make the video presentation work, and there are several comments to the effect that others were having difficulty viewing the presentation.  I used Firefox for Windows, and after installing the required plugin it played just fine.

Just to underscore another powerful trend, a number of manufacturers announced new camera and camcorder memory cards at the Consumer Electronics Show earlier this month, and the Washington Post covers several. Being a tech person old enough to remember spending $1,000 for 1 megabyte of computer memory, it boggles my mind that Panasonic will be coming out with an SD (Secure Digital) card that has a capacity of 32 gigabytes. In one of those little camera chips about the size of a postage stamp, you’ll be able to store eight hours of high-definition video. Prices haven’t been announced, but I would guess that little bitty chip will be in the $1,000 range. Not even accounting for inflation, that’s buying 32,000 times more memory for the same cost.

Another way to look at it - in 1985, a megabyte of memory cost $1,000. Today, it costs 3 cents. At that rate of change, in ten years it will cost .04 cents, or four hundredths of a cent. Free, for all intents and purposes.

This is a challenge we haven’t really addressed in our planning for educational technology. We still focus on how costly things are, and often plan for resource-starved settings. How would we plan if we operated on the assumption that the technology will eventually be free? Back in December Guy Kawasaki shared a video looking at that exact concept - planning for when technology will be free. It’s a presentation by Chris Anderson from Wired Magazine, and it’s an overview of a new book he has coming out. It’s pretty challenging, but I think his message is very important, and one we need to start considering sooner rather than later.
