Hi Ahmad, I think we're pretty much saying the same thing. But I don't necessarily agree that a teaching guide is always required.

If you're interested in the subject, there's a swathe of reading material in the field of systems thinking and knowledge management related to the subject of cognitive and applied learning - e.g. Ackoff, Kolb, Fitts and Posner etc. Certainly too much to get into in a medium designed for a largely different use.
And in answer to Phi, suffice to say, we are ultimately responsible for our own education - in the broadest sense of the word. To mangle a quote, learn all you can learn, be all you can be, share what you know.
"Teachers" are like Buddhas... you know what to do if you see them on the road...
