I think I'd prefer overview, exercise, details. You need some kind of mental framework. I guess you don't just dive right in, otherwise you wouldn't be getting good feedback ;)
What I really hate is explaining the solution before explaining the problem. It's a terrible way to teach and it's quite common. I like to say that there are two bad ways to teach: The cookbook (do this, then do that) and the maths textbook (solutions without problems or context). The good way is a combination of them with some additional things that neither of them has, like motivating examples, relevant anecdotes etc.
