Christopher,
I really like this simple idea!

Years ago I had a kid on a bicycle under the front end of my car lifting my front wheels off the ground as I slid down a steep hill bouncing off the curb. When the kid was asked why he did not stop at the intersection, he replied that he had only had time to fix the gears before a test ride. For years I would kidnap a youths bike if it did not have brakes, I would install the brake for free, and tell him about the kid that was under my car and I would not not let another kid end up under there as long as I had the skills to do something about it.
My advice is teach them brake systems first. In a safe parking lot have two kids at the same speed see who can stop more effectively, one who only uses a front brake or only a rear brake. Physics says a object moving forward and being pulled down by gravity will have the best braking force from the wheel that is forward and down. Test and find out for your self

Be sure you have thought out what your goal is. The ability to take care of most of the basics, Air (tire, tube, wheel truing), Brakes, Chain/cable/crank arm, derailleurs adjustment including hanger alignment in a month class, or longer course to cover things they may not see at their stage of learning/experience.
A-B-C-D covers 80% of what comes through our co-op doors and I think of it as Mech 102, 101 being righty-tighty, tool use & care, etc Take a look at Primitive Pete for that.
The remaining 20% is bearings/advanced and if you can do a hub, then head sets and bottom brackets are just a variation. That can be an "add-on" or a shadow type deal for the first couple. Then let them practice on a shop bike. Wheel building is a separate deal, some may not be interested plus it's a parts cost for a co-op even if it is just spokes.
By teaching the A-B-C-D everyone learns the basics and can lean on each other as trouble shooting becomes necessary.
A speciality per person seems to me to be a lot to coordinate to be sure a full team is present.
Use the Park Book for the basics and the many videos on-line as necessary. If possible, let the kids research some of them as a recurring project.
I'm former military, and for many of the skills, the idea of get the basics taught and then let them do OJT for the more advanced tasks has worked pretty well. Not too different from a riding class then off to do it.
Nothing's perfect, but I do the A-B-C-D in three hours twice a month. A & B hands on their own bike, remove/replace both wheels and break down/reasemble the front, then patch a shop tube, C & D as mostly show and tell, if their derailleur needs adjustment it backs up what the limiting screws don't do.
They leave the class able to fix a flat and if their brakes aren't working correctly, they now have an idea why and if they don't have the tools or find they can't quite do it on their own, they know what they want to do when they come back. It would be easy to do A-B-C-D in 4 90 min. classes. Spice it up with horizontal vs. vertical dropouts, mounting a rear wheel with the vertical derailleur mount so they learn to get the wheel straight in the stays. Coaster wheel to learn about the brake. Add in the advanced once a quarter. Any more I tell students to set aside 6 hrs on a Sat with nothing else on their schedule and just come back to the co-op to be walked through it.
Take what you can use, just my thoughts.
I posted some stuff to the wiki, including some open source anatomy pictures. I'll send you my syllabus/class hand-out tomorrow.

Hello People,
Our developing high school bike program in Melbourne is in need of a fantastic workbook for our students to utilise. Our resources are completely outdated and participant numbers are increasing so we need a resource that will keep our students developing and learning.
Contents we'd love:- Workshop rules and procedures- Worksheets on all the specific processes and anatomy's- Activities- Diagrams and explanations- you get the idea.
We understand that these resources take a heap of time and effort to compile and we'd be so very grateful if someone was willing to help out by sharing theirs.
Best Regards
Dominik
