Where I was teaching in MN we used station teaching for school groups.
One or two stations on the flat for boot drills and moving around on skis.
The rest in parallel lanes width and length determined by that days snow conditions and crowd.
Generally lanes set up using traffic cones to define the lane as well as when and where to turn.
One lane for straight runs and stopping.
One lane for mini turns ending in a left or right turn to a stop.
One lane for mini turns ending in a right or left turn to a stop.
One lane of a slalom course forcing a large enough turn in each direction to control speed.
An explanation of the chair lift, a quick quiz about the skiers responsibility code, and off they go.
From the instructors perspective. Kids get off the bus and are led to the lodge where expectations and rules for the day are laid out.
Those few with their own equipment get ready, well the bulk of the kids are talked through the rental form.
The first instructor up takes the kids with their own gear out and leads them through the stations. Meanwhile the second instructor up takes all the renters who have skied before through the rental shop and through the stations. If they can indeed ski they're out of there in less then 10 minutes leaving those instructors free to cycle back to earlier stations as needed.
The rest of the instructors lead groups of 8-15 kids to the shop in ~10 minute intervals or as quickly as the shop says they can handle them. when all the instructors are gone the chaperons take groups to the shop.
On the snow instructors lead their group to the first station. Basically the Instructor gets in the loop walking/skating up and skiing down offering constant demos and feed back. When the next group comes up behind them one instructor takes the ones who have completed the task with to the next station while the new kids and an instructor stay and work the first station.
Basically kids and instructors cycle through until all the stations are covered then just cycle station to station as need for help at particular places become evident or at least the need to turn right after a half hour of turning left sets in.
After most had gotten through the stations the few who needed more help would wind up in more traditional groups as the need to staff each station lessens.
On an average day we could, with 5 or 6 instructors, take 150 to 300 off their bus to free skiing in less then 3 hours.
As a supervisor it made it easy to rotate instructors in to help with a crowded station even if they only had 15 minutes. Most of the instructors enjoyed working up their own station shtick. Best of all (from a supervisors perspective) it made instructors who really understood what you need to know to take the next step, and how close to perfect it had to be preformed to keep progressing.
We occasionally would use them with the public if it was real busy, but generally we had enough staff on busy days that it wasn't necessary.
