This is sooooo true. I am one of those right brained people who is a visual learner....Reading about photography is torture for me, so I try to find different ways to learn. I prefer watching videos and seeing examples. I would love to find someone who would be willing to teach me a few things!!
I'm going to rant about this (warning). Tami, this is widespread throughout our society now so please don't take personal offense. I have spent decades being very disturbed about this brain-sides-learner-type education babble. If it is true, and I don't believe it is, but if it is, then it's very unfortunate that those poor people are so disabled. And that's because there is a qualitative difference in what can be learned and how learning can take place if that, "I'm right brained, I can't do math cr*p," is true. The Inverse square law is a good example. That's a very powerful principle particularly because it has application not only to photography but to physics and science in general. It also applies to electricity, gravity, etc., so that best expressed we say the strength of a signal is inversely proportional to distance.
Abstract learning is powerful and efficient and it empowers the learner by improving their ability to learn. Another lighting example is helpful: You set up a studio product shot using strobes and when you finally meter the shot you get f/5.6 given your ISO. You're unwilling to raise the ISO, but you need f/16 for adequate DOF so what to do? Just fire the strobes multiple times with the camera shutter held open. How many times? That's easy; 2 cubed. For over twenty years now in a college classroom I've had to teach and explain this to a room full of college students, most of whom had long ago convinced themselves they were "visual learners." So I could never just say, "You're trying to alter the exposure by three stops: f/5.6 to f/16. A stop is a factor of 2 so the answer is 2 cubed." Maybe once every three years one of them would hear me say that, look at me, and thumbs up, lesson learned. The abstract principle of exponentiation applies. It's a core mathematical principle of immense power. You're mentally crippled if you can't use it.
And so what did I have to do for the "visual learners?" I'd collect the empty soda cans in the room. "OK, fire the flash once and that's one soda can" and I'd put the can on the desk. "Now how many more soda cans do you need to double what you see? One more? Good! OK, now it's going to get hard. Richard, how many more soda cans do you need to double what you see now?" OK, OK double is a difficult concept. Count the soda cans on the desk...
This was a class of college students -- I shouldn't have had to waste that time so the "visual learners" wouldn't be left behind. What if you needed f/22 instead of f/16 -- a four stop move? 2^4 or are you going to start stacking soda cans?
This learning modality nonsense is far less and explanation of how learning and teaching takes place and far more an excuse for failure.
