Building a Linux Computer Lab for Schools?
joseamuniz asks: "After giving Linux classes to Secondary School Teachers, I got in touch with a non-profit organization called UNETE. This association has donated 1,523 computer labs to public schools in Mexico. I told them about Linux, and they are interested in equipping a beta computer lab with this Operating System, with Intel PIII, 256 MB RAM PCs. The more they like this lab, the higher chances to include Linux in the new labs donated by this institution." What hardware configurations and software packages would you install on such a machine to show off the real power of Linux in an educational environment?
What educational software packages are available for Linux? Something tells me they haven't ported Oregon Trail to Linux yet.
Windows and Word on a second partition.
Only 256 megs of ram, so I'd stay away from the heavy guis. I'd probably use the litght weight knoppix (runs with xfce) and limit the number of applications on it. The only thing I'd add is OpenOffice. then I'd install it to the drive.
Either that or I'd run K-12 Linux terminal server project. which is a fine network absed distribution.

Make absolutely sure that any software these schools really want to run either has a native Linux version, a practically-idential Linux version, or will run flawlessly under WINE. If the schools can't use the software they want to, it'll leave quite a bad taste in their mouths about Linux.
It doesn't show off the power, but remember the KDE has a set of "Edutainment" programs of varying quality.
I've personally used some of these for school, and they are quite good. For example, "Logo" is replaced with KTurtle, and there are a few maths programs (KPlot for graphs and Kig for geometry, among others). There are quite a few language tools too. There is an impressive chemistry program which lists the periodic table and information about each element, too.
So KDE includes a great base. More schools should use it (especially when combined with KOffice)

Have you looked at the K-12 Linux Project yet? Seems like that would be a good place to start.

Just to preach the common trend, I would suggest Ubuntu for the distro. The base desktop install is exactly what you would need. You get Firefox, Evolution, Gaim and OpenOffice.org. It's a no hassle install, it's Debian and you can get support for it if you want. I wouldn't suggest holding off on Ubuntu until their next release, because it's pretty slick and comes out in about 2 months.
Also, you can get free CD's from them. Just request 100 or so and have them shipped to where ever that organization is. Technically you only need one, but you can give them out to the students if they like it. It comes with a livecd, so they don't have to destroy their home PC.
Like it or not, these machines will be rooted or get seriously fouled up at some point. This is actually one area where Linux really shines. You can set up a net boot environment (or live cd) that brings the box to a known good state. Don't keep any real data on these boxes. You don't even HAVE to keep a desktop image. You can NFS mount / if you really wanted too (though it's probably better to have an OS image local that can be over written easily).
This means you'll probably need a more beefey (at least in hard drive space) server that this lab will live off of, but I assume you already knew that.

I'm a total newbie to linux, so I'm not qualified to give detailed advice. What I will say, however, is that after playing with lots and lots of different distros, I find Mandrakelinux to be the simplest and most user-friendly introduction to linux. So I would recommend installing Mandrake to give the teachers and students a good flavour for linux with an easy transition. It comes with just about everything you need to get up and working fast.
Im afraid most of the educational software taught at the school level is built for windows and wont support other OS's very well. So the primary thing is find out which software is needed by them and get those working on Linux. Not many school children are going to start out running command line programs, or coding in perl and C++. Most likely, they will browse, use rich text editors/spreadsheets, chat apart form educational software. Unless of course, we are talking higer grades, even then, not all of them are going to be computer professionals. -imho

The major cost was time in getting it set up since all the computers have a different configuration.
BTW, VectorLinux hardware detection on these old machines is awesome. Let's just say that after setting up nearly 50 of them, I've only had to edit the XF86Config-4 file two or three times. Also, no problems with strange cards. Also, VL, being Slackware based, is extremely FAST on old machines and boots into IceWM nearly as quickly as it takes my new 1.8 GHz Athlon to load KDE. (Please no flames about how KDE is bloatware, we've all been there.)
Point of the matter is that if you have the time and you have old hardware, setting up one of these labs is a snap.
Don't go any farther than http://www.k12ltsp.org/. They have the best all around linux solution for k-12 schools. Period.
I can speak from some experience on this. At my university, they had very few Linux machines. The labs that did have them were for our calulus classes. The ran Maple under RedHat. The systems at the time were probably very close to the systems which you describe. They were a pleasure to use. I think Maple would serve to show the power of such a system.
Thomas Jefferson High School for Sci./Tech.- this school has an entire computer systems lab with running on Debian, complete with Cray SV1 and cluster of 386's. The lab is run largely by student system administrators who know and learn much about the Linux operating system during their stay at TJ, which helps to prepare them for entry into the business world and tech industry where UNIX based operating systems are the common standard. TJ is a public school located in Fairfax County, Virginia. It also has a Wikipedia entry that goes into more detail than my post here (Sorry for lack of link, but Wikipedia seems to be running slowly for me as of late and I couldn't get the page).
Ok, so, Gould Academy is where I went, and they use linux for everyday use, in the labs, classrooms and even faculty offices. Mostly what students learned to use was IceWM, Konqueror as a file manager, OpenOffice, Mozilla (although Firefox might be a better choice), gAIM (not in class!), the Gimp and xpdf. /home directories would be good.
They didn't have a big budget for the computers, so they used the old 386 (true, I've used them!) and a bunch of old machines, bought a dual Xeon 733 MHz server, and ran LTSP on the whole thing. They had a special file server with a quota of about 1 Gig for students in their home directory, which was plenty, and a separate mail server.
I think that if you install those PIII with LTSP you'll be missing out on responsiveness, so instead maybe install the same distro on all of them, and use a NIS domain for login (with gdm, or even better, Entrance, which is prettier than gdm to look at!) and getting one machine with several drives to use as NFS server for the
Then if you want to start a multimedia class, it turns out a lot of people are actually thrilled when using Blender. A whole bunch of people active on Blender forums right now are not much older than 13. I've basically taught my Linux professor at Gould to use blender, and the Advanced Linux class at the same time.
I think that's plenty of things to show eye-candy and the real horse-power you can get in the managing of such a lab with linux.
Also, most of these programs have spanish localizations, iirc.
---- I am certain of only one thing : I know nothing else.
Those who use only windows at home and at school learn just that, how to use windows.
Force them them to use something else, and they no longer just know how to use windows, but how to use a *computer*.
I've heard it said that the best way to learn how to learn language is to learn many of them. This is why we teach spanish, or why a good CS program should involve several different programming languages.
The concepts for using any OS are the same, and that's what should be taught in school, not exactly where to find what button in Word. You wouldn't say that kids should skip reading Shakespeare because every newspaper in the country is a 100% modern English shop, would you?
There is in fact a debian-based linux distro being developed which is targeted directly at schools.
Take a look at the Skolelinux project at http://www.skolelinux.org/portal/index_html
Look! No sig!
Forget about distro arguments, forget about how cool kdeedu is, forget about how amazing (whatever, I don't use gnome, but I'm sure there is something).
Concentrate on the fact that you have slow machines running undocumented software that are being demonstrated by people who do not know the software. Every one of those issues needs to be resolved, and if you want the lab to be a real success then aim for the goal of making everything run smoothly every time.
The machines will feel slow, so you will have to work around this somehow or choose a light wm and cope with the added complexity it brings. The software is mimimally documented, and what documentation exists will need to be rewritten for your target level and language. Think howtos with step by step screenshots -- the reason cheesy computer courses use those is because they work... And the teachers need more than just a training course if you expect things to go well, they need a depth of experience.
So to start with the hardware. Linspire does not run well on a typical 500MHz machine because it needs more ram. Decide for each major choice (distro, window manager) how slow it is, and if it will feel better if you choose the fast but hard option or the slow but easy option. Generally, people who haven't used 3GHz computers cope with slowness more, so decide based on their experience rather than yours. If the machines have high ram I would go with KDE, low ram and I'd go with enlightenment or similar.
Next, concentrate on making sure every single thing these people want to do will work flawlessly first time. Make the documentation perfect. In many ways, the docs will be more important than the software.
Now you have the computer side working, concentrate on teaching the teachers to the point that they feel 100% comfortable. It is important at this point that no changes happen to the software. If the teachers just know how to do their lesson but don't feel comfortable then that discomfort will show strongly.
I hate to say it, but this sort of project is a lot of work even with awesome software running on blazingly fast machines. You're not targetting geeks who will overlook details such as user interface or docs because a program is cool. Of course, if you drop your standards and just deliver something that will appeal to geeks, well that's pretty easy with linux.
If you do manage to get the software, training materials and educators all working smoothly, then don't change a thing. Say openoffice 2.0 comes out and would fix a number of issues, ignore it! You can only retrain geeks fast, not people. You'd break your howto with items shifting menus or even just icons being tweaked. You'd upset your educators who don't have the depth of experience in software to cope.
Oh, and please publush everything at this point -- collaborative development doesn't just apply to software.
Good luck.
Check out Skolelinux (Distrowatch page) (Linux for schools, Norwegian name). Made to work perfectly with LTSP, and based on debian stable. On the install cd you can choose to install the Skolelinux server or thin clients, or a standalone install. Plenty of educational software availible. The thin client install runs fine on older hardware. Give it a try.
OK before anything, I'd ask the guys to forget all that bullshit about sombreros and guys wearing sandals.
I live in Mexico City and we're SURROUNDED by "ducky" schools teaching you to be a "computer technician bachelor", and they teach you Windows, Word, and all that crap.
You can find cybercafe's every 2 or 3 blocks.
People in here use MS Word to use their homeworks. Go to a cafe and you'll see thousands of "Learn Word" books, booklets, magazines, etc. You can buy the tutorials off the streets.
Children in elementary already use Word for their homeworks. Most kids I know already got a MSN account (just don't ask me about their grammar or *shudder* spelling).
In other words, no, we don't need any more Microsoft training, thank you.
And with the current trends, Linux will be much more popular 10 years from now. Want to prepare them for the future? Teach them Linux.
Or Squeak, which already has tons of educational content (the primary objective of the language).
