So, regular maths today [ie AS level maths class, not AS further maths], the following is observed:

*teacher has written most of a worked example*
"... and that leaves us with x2 = -1 or 1/9. Now, we know we can't solve x2 = -1, so we'll just cross it out and focus on the 1/9"

HANGONJUSTAMINUTE.

We'll just cross it out?!

I put my hand up in protest. "Eh? Surely there is at least one answer involving i?"

"Well yes there is, and we'll be coming onto that in further maths this term".

"So, are we not going to cover imaginary numbers in A level maths? At all?"

"No."

I am now once again disgusted with the state of the education system in this country.

Hey, know it's been a while, but can't help adding: It's not just your country! Sometimes our teacher won't teach us stuff because we're not supposed to learn it until next year, and sometimes she'll teach us formulas and say "But don't use it on the exam, because it's not covered till next year." We're not allowed to use stuff we know because we're not supposed to have learnt it yet. jfkdsla;jkflsa

Same happens here, I am in brazil.

It may seem surprising (I know it made me all "whah?" when I learnt that), but this "You are not supposed to learn this now" is a teaching technique used to encourage students to learn maths. As it seems to go, most students are overwhelmed with too much information in the subject and drop the class without a second thought if they feel they need to take in too much information; it also forces the few that are interested in maths to pursue it outside of class, and thus learn other views than their professors (and start to perceive maths as a science and not as a recipe), making it more likely for them to pursue maths as a career instead of being just contented with they learnt in class.

I was taught that in maths educating class, so I'm not sure how well it stands for other subjects. But must stand well in maths, since it's so widespread a technique... (or maybe it's widespread because you can be lazy when you are a teacher and use it. =P)
