When I started building websites, I started with a Dreamweaver course at the local college. It was a disaster. The pupils were all of different abilities and standards – the teacher was either too fast or too slow for each pupil.
If you have the resources, in my honest opinion you should give them each access to the video training course so that they can each progress at their own pace.
If you want to teach them something really useful, then www.remarpro.com is what you should be teaching.
