I've done on-site
MapPoint training for several different companies over the years. I finally settled on teaching out of the
MapPoint for Dummies book. Although we end up spending some time flipping through the pages and aren't as focused as say if we used a tight workbook, the people getting trained get a sense of what's in the book and walk away with a good reference they are not as likely to throw away as a 20 page workbook.
Also, at least half the time training is always (so far at least) working with the company's data, helping them explore the options in MapPoint and different ways to look at the data.. sort of like a workshop. No matter how much I prepare, we always come up with new ideas during the workshop sessions.
