It is very good. There's an educational philosophy around this that state that people who are new need to know "why should I care" first, then "how do I do it" next, followed by "ok, why does it work that way?" last.

When you're cooking, you follow a recipe. When you are learning to be a cook, you graduate to figuring out why you do it the way the recipe did.

And when you get really good, you start saying things like "Well, I wouldn't teach people to cook THAT way! That's wrong!"
