I do not have lots of experience regarding teaching professionally, but I have been a student, and my field of work requires me to be always on the frontline, learning new things all the time. It is also very important to remember one thing, that many, many people forget. As Einstein said once:
"if you put a monkey and a fish to climb a tree, the fish will always think that he's dumb"
What does that mean? I am confident that you got it. There are people and people. We belong to the same race, but we are not equals. Our minds developed through several processes that depended on the environment in which we grew up, and consequently, applying the same methodology to everyone might not work. Well, not might, most probably.

But there is a general order that might be followed.

For starters, the main thing to understand is the concept of the problem that we are facing. With science and physics especially, it is extremely useful to be able to visualize the problem, to have a clear idea of what we have in front.
Once visualized, we can think about it. what am I looking at? what might be the reasons behind such behavior, such phenomena? What if I change this or that? what happens? A brainstorming session will help a lot to space out and will allow us to define some constraints.
Then, and only then, we will take a look at the work done by the giants of the past, the minds that allowed us to create the world as it is (we'll open the book and take a look at the boring theory that's written inside). Once we will identify the laws, and how to look after them, we will try to apply them to our situation, and then, repeat them with other exercises.
Does it sound a bit better than falling asleep of boredom in the middle of the book?
