What is a good approach learning opengl es 2.0?

Question

I was already messing around with some coding and finally think that I am finally ready for the OpenGL part, then thought again and decided that I need to be guided by how to learn / remember OpenGL ES 2.0!

Well, basically, I know how it works at a high level, and then when I start entering code ...

I see a bunch of parameters, I refer to some documents, I fill in those parameters, I see some more parameters, I refer to more documents, (loop) MVC comes in, I get completely and utterly confused! Brain crashes. 

I'm trying to do some simple things on the iPhone, I would like to find a sequence of thoughts about the guru, for example, some kind of checklist or order to do something so that what I do is always clear!

For example, something like:

 Arrays of numbers always come before shaders (some sets of program lines that always appear in a certain order) 

Now I have a high level understanding like this:

I would like to know what are the usual steps involved in expanding all this high-level knowledge, such as tags on a website!

I tried to read some lessons, and I will try to do it again, to try to learn the general steps / order, to do this, if someone can speed up the process, I will be very grateful! Am I asking too much? = P

Answer 1

I highly recommend this GL book tutorial on iPhone

This is especially useful for fairly experienced developers who start with GL. If you start at a more novice level, this can be confusing piecemeal.
