Netbook Update

Ben Grey has a post over on The Edge of Tomorrow that's worth your time if you're in the position of deciding what kinds of devices to purchase for your students. You really should go read the post (and the comments), but I just wanted to pull out my comment as some folks began investigating netbooks after a previous post of mine.

So, here was my comment (in the context of that post and comment thread, but still mostly makes sense on its own):

Let me just contribute a little info about our experience with netbooks running ubermix.

First, they clearly are inferior to the MacBooks when it comes to video editing and photo manipulation. Now, you can still do some basic video editing on low-res video, and also some basic image manipulation (cropping, brightness, etc.), but you certainly wouldn’t want to do a ton of that on the netbook unless you absolutely had to. I also agree that iLife is something that’s not matched elsewhere, which is why having some iMacs or MacBooks around for those purposes is probably ideal (which is what it looks like Ben’s district has done).

Second, a Mac is going to be a little faster than the netbook at lots of things, and that’s nice to have, and typically the screen is going to be larger (both physically and in terms of pixels), which is also nice.

Third, certainly the touch interface of an iPad (and perhaps a MacBook soon?) is a great addition in many instances (and a drawback in terms of text entry, fingerprints, and scratches).

But I don’t want to get into that part of the argument, I feel like Ben looked at many devices and tried to make the best decision possible for his students, so let me talk a bit about what our netbooks running Jim Klein’s ubermix can do, as that might be helpful to folks reading this thread. Our current district approved model is the Asus Eee #1001-PXD-MU17-BU at $259.40. I can’t tell you for sure how long the battery lasts because it lasts an entire school day, but my best guess is around 8-10 hours. Our two-year old ASUS netbooks last between 4 and 6 hours, meaning they do occasionally run out before the end of the school day. In comparison our (Dell, running Windows XP) laptop batteries last 2-3 hours and also seem to degrade and need to be replaced more quickly.

The machines boot in less than a minute (and shut down in about 20 seconds) and you have a fairly extensive list of standard software to choose from, as well as you can add just about anything open source you like. Since, like lots of folks, we are moving to more web-based software, it can quickly and easily access Google Docs (and the rest of the Google suite) using either Firefox or Chrome. It does run Flash, and Java, although occasionally we’ll run across a site that requires a specific OS (typically Windows, sometimes Windows or Mac). In general, accessing the web is quick, easy and functional.

If you don’t want to use Google Docs or something else online, it does come standard with the current version of LibreOffice, which is full-featured enough for almost any student. It also has Audacity, Skype, Gimp, Google Earth, GeoGebra, Scratch, Webcam software, and a variety of other software. The only software we’ve added to it is Logger Pro to run our science probes and some Dell printer drivers (although we have customized the look and feel quite a bit). You can, of course, download and install just about any open source Linux software.

It is easily customizable and has a very nice imaging process. Once you create the image you can copy that to a 4 GB or larger flash drive and then the imaging process takes about 6 minutes per machine using that flash drive. What I do is copy the image to 16 or so flash drives, then set out 16 netbooks on a table and start imaging. By the time I get to #16 the first one is usually done imaging. If your image is complete, then you’re done. What I do because we have netbooks in lots of different rooms is I create one image that has all of the possible printers that our netbooks print to setup on them, then after I image I simply delete all but the one that needs to be there (faster for me than copying a new image to all 16 flash drives). That probably adds about 2 minutes to each machine to do that. So, by the time I image all 16 and then work my way around and delete those printers, it’s probably about 15-20 minutes per set of 16.

These machines are not locked down (although they can be), so students can – if you or they choose – customize them. While that’s scary to some folks (again, you could lock them down), the beauty is that the built-in restore function works in about 30 seconds. On boot up you can restore to your image and it adds about 30 seconds to the boot process and keeps any user documents. Or, you can choose to completely restore – wiping out the user docs as well – and it’s about 3 minutes. You can even set them to auto-restore back to the image on each boot if you’d like. (And while I typically do it, the process is easy enough that any teacher could be given a 3-step list of instructions to restore on their own if necessary.) Other than a little bit of knowledge to first create the image (and, trust me, I only have a little bit of Linux knowledge), these don’t require much support. (In fact, that’s partially why our tech department approved them, because they don’t have to support them.)

While I don’t use this feature, you can push out updates to them from a server. A script is installed as part of your image that checks for updates, and then if you put a new update out on the server it will grab it (either at startup or shutdown I believe). I’ve chosen not to mess with that, at least partially because so far each year the updated version of ubermix has been enough better that I’ve simply chosen to reimage all of my netbooks (again, at about 15-20 minutes per set of 16, working by myself, that’s not bad, but your mileage may vary).

While our netbooks don’t go home with students, they are used pretty heavily and we’ve had very few hardware issues. In four years we’ve had 2 or 3 cracked screens, a couple of failed hard drive/ssd drives, and a fair number of keys that get picked off and then we’ve had to replace the keyboard. They connect easily to our open wireless network and seem to match our Dell laptops running Win XP in terms of download speed via wireless.

While we did do some training with our Language Arts teachers, it really wasn’t around Linux or the netbooks, it was around what to do with them. Teachers and students both just pick them up and use them – if they are comfortable using any computer, they are comfortable using these – not really much of a learning curve. We have them available for check out in our media center, and also in our Study Center, and students – even ones that don’t have a class that uses them – don’t seem to have any issues using them.

So, I’m not necessarily trying to support one side of the argument or the other, but I think many folks reading this discussion don’t have any experience with the specifics of what Ben is talking about with his netbooks running ubermix, so I’m hoping this helps a bit. For us, the cost factor (as well as the ease of setup/support) is huge. Yes, I would prefer to give our students MacBooks over netbooks, but at a greater than 3 to 1 price ratio that’s a tough call to make. I think we’ll continue to see devices evolve. In the meantime, I would encourage everyone to at least explore a netbook running ubermix if you think it might meet the needs of your students and teachers.

Just Write Poorly. In Public. Every Day.

Seth Godin has some advice about writing:

The reason we don't get talker's block is that we're in the habit of talking without a lot of concern for whether or not our inane blather will come back to haunt us. Talk is cheap. Talk is ephemeral. Talk can be easily denied.

We talk poorly and then, eventually (or sometimes), we talk smart. We get better at talking precisely because we talk. We see what works and what doesn't, and if we're insightful, do more of what works. How can one get talker's block after all this practice?

Writer's block isn't hard to cure.

Just write poorly. Continue to write poorly, in public, until you can write better.

I believe that everyone should write in public. Get a blog. Or use Squidoo or Tumblr or a microblogging site. Use an alias if you like. Turn off comments, certainly--you don't need more criticism, you need more writing.

Do it every day. Every single day. Not a diary, not fiction, but analysis. Clear, crisp, honest writing about what you see in the world. Or want to see. Or teach (in writing). Tell us how to do something.

So, are you having your students write every day? In public? I know I'm not (although I'm starting to have them write a bit).

I think we're often overly concerned about the quality of our students' writing, and whether it's "good enough" to share. Now, to be clear, I think our students should be concerned with the quality of their writing, and should strive to get better at communicating their thoughts. But if we let the worry about what others will think get in the way of having our students write more, and for a larger audience, then we're doing them a disservice out of fear.

This begs the question, of course, about how much our teachers are writing. Particularly our Language Arts teachers, but really all of our teachers. If it's so important for our students to write, how come we're not modeling it?

Do you write every day? In public? Why or why not?

One. Third.

Two different data depictions crossed my information stream in the last twenty-four hours. Let’s see what they have in common.

First up is this data visualization of PISA scores put together by Michael Marder, a Professor of Physics and the Associate Dean for Science and Mathematics education at the University of Texas, Austin. Unlike the usual way these scores are presented (particularly to the American public), this time the U.S. scores are broken down by poverty level. Here’s a screenshot, but you really should explore the interactive Tableau visualization or view the mp4 that Professor Marder narrates.

 

Second was this report (pdf) from the Colorado School Finance Project, depicting the characteristics of Colorado’s K-12 population over the last 17 years. Again, a screenshot, but take a look at the entire PDF as well.

[As you view the Colorado data above, also keep in mind the current budget situation facing Colorado school districts (pdf).]

Now, regular readers of this blog (are there any of those any more given my recent blogging drought?) know that I have some serious concerns about various aspects of our education system, and I believe there are many changes we need to make to best meet the needs of our students. My current frustration, however, is that I feel most of the talk around education reform at the national, state and even local level is not only about the wrong issues, but also misreads the data and ignores the most important factor affecting what they (not I) believe is the best metric for measuring how our students are learning.

For some reason Alex Trebek’s voice popped into my head while thinking about this.

Me: I’ll take Education Reform for $1000, Alex.
Alex: It’s the Daily Double! How much will you wager?
Me: I’ll bet it all on Education Reform, Alex.
Alex: That’s very bold. The one issue that well-known national education reformers might actually be able to have an impact on, but also the biggest issue they pointedly ignore.
Me: What is poverty?
Alex: That is correct! 

 To be clear, I don’t think poverty is our only issue in education. Nor do I think we should use it as an “excuse.” But as long as reformers think that "test scores" and "accountability" are the best path to meeting the needs of our students, then I think they need to get past the rhetoric and address the underlying issue of child poverty. The hypocrisy of misusing data to justify asking for more and more data from schools in order to judge how well we’re doing is stunning.

A full one-third of public education students in Colorado are on free lunch. One. Third. Until we address that, please spare me any more discussion of CSAP/TCAP/ACT/PISA/TIMMS/NCLB/RttT/YAA.
