Thought is innate and based on experience but symbols and language are learned and are used to tranmit our thoughts to another person.

This was my first reaction too on reading the thread this morning.. But isn't education besides teaching facts suppose to teach one how to think and analysis? Also we assume that the students are taking the course to become photographers while they may in fact be going to engineering lens and other similar jobs in the photographic industry.

Yes, but a quick look at any lens or light meter tells you just as much without any calculations at all. Each stop signifies a factor of 2, so to get 4x the amount of light, click over 2 stops & you're done. Teaching a student all this math (if this is what the thread is about, I wasn't in on the beginning) is very academic. It's not anything a photographer with a camera in hand would ever do.
