This is actually a subject I have had with folks in the past, but mostly because of the LACK of education.
As Derrel states, there really is no longer any "rules" (at least at this point in history) to make for the system we have.
When new forms of physics are discovered, that may change.
Now bear with me here. As someone who has read
Marcus Vitruvius Pollio's Ten books of Architecture, watch the "Ways of seeing (1970's), and a host of other books, videos, etc, read books on ancient prose, poetry and a host of other arenas of geekdom, (Sun Tzu Art of War, the modern "wooden Book" series on Design, the Trivium, Quadrivium, Science, the Reg Veda, The Wheel of the Law, etc, ) teaches the fundamental aspects of day to day life and the interconnections of concepts becomes clear, the real context I think should be on the foundations of basic art theory.
Then show the mechanical aspects of photography, especially the relationship of the lens to image plane, and how moving and manipulating that will enhance the images and/or change the overall effect.
Look at the rules on light behavior and the effect of shadows. But all of this has been studied to death for literally 5000 years. The one arena that IMO is the most important is to teach how to look for the unusual in the usual.
