This format is actually pulled from Public Speaking, where it has been
shown that listeners retain the material better if you basically do:

1. "This is what I'm going to tell you"
2. Tell them
3. "In summary, here is what I've just told you"

It's also good practice to limit an instructional lecture to no more than
3-4 main points.  Done right, I think this is actually a very good format,
even in a book.  "The Pragmatic Programmer," for example, follows this
format and it's one of the best programming books I've ever read, and
also one of the most concise.
