My English teacher liked to tell us that 2 + 2 = 5.

A half cookie for an easy reference.

1984, and only quarter of a cookie please. I'm on a diet from cookies.

quite a bit of science i learnt at GCSE level turned out to be dumbed down to the point that it wasn't actaully true. I can't remember specifics apart from that some of it was about light and gravity, but i remember starting Physics AS and think "But we were told differently in GCSE"

Our physics AS teacher told us on the first day that everything we though we knew was wrong, as it was only a model. Half a cookie for that reference.

"You can't take the sqaure root of a negative number" Is a quote out of context. The other half is: " and use it as a real number in mathematical context."

My Media teacher taught us about the Hillsborough Disaster, using the Sun and the police reports as the major sources.

For those who don't know, the Hillsborough Disaster happened when Liverpool played Notts Forest a while ago, there were too many people in the stadium and more outside trying to get in. The police were told to allow the people outside to come in, creating a crushing effect in one of the "pens" (high-walled fences stopping the fans getting onto the pitch), and when they tried to climb the fence to get out, they where beaten down by coppers. The Sun reported a police-skewed version of it, suggesting that it was entirely the fans fault. 97 Liverpool fans died that day, and the police chief has since been prosecuted for gross negligence. I called my teacher out on this, because the way that she told it the Liverpool fans were a bunch of animals who were the sole cause of the disaster. My mum would have been a 17 year old girl in those stalls, but she had her ticket nicked whilst she was on the train down there.

My health teacher told me that babies come out a vagina. I was so insulted that I almost said something, but I decided to just leave a leaf of cabbage on her desk. We all know the truth.

The Sun were proper douches after Hillsborough. I'm a Liverpudlian myself and no one buys the Sun here these days, even after the Sun issued an formal apology.

One of the few things my high school taught me was that I had to go on to university and get a degree, just because I was good academically.

Bollocks! They were just a bunch of elitist snobs who measured success with grades and didn't care about students, they just wanted to look impressive!

In case anyone didn't notice, I don't like that school very much...

Ditto, one major gem I have found in my working life is that, qualifications will get you the job, but skills and experince will get you respect from your peers, and in some cases students

OP: 'Teachers will allways be right'. A friend of mine argued with the teacher in a music lesson, and when the teacher insisted he teach the lesson 'as he knew everthing' he performed the piece flawlessly and was given detention for 'talking back to the teacher'! Since when did teachers become these all-powerful, all knowing creatures?

"The civil war was about slavery"

[sarcasm] shure was herp durp [/sarcasm]

Our usually pretty awesome chem teacher told us once, that a human is pretty much dead with a blood alcohol of 2,8 to 3,0. That was two days after I ran into a police control on my bycicle with 2,6...

Probably everything I was taught in health class. A few classic claims are that tobacco contains radioactive compounds, men are 6'3" on average, and that eating McDonald's in moderation would get the same result as Morgan Spurlock in Supersize Me, because you're apparently taking in the same toxins and excesses, just at a slower rate.

Also, more of an omission, but my elementary and middle schools did not teach a difference between "than" and "then." I used "then" for everything and never got called on it or lost points for it.

"Demonic possession is a reality."

In. All. Fucking. Seriousness.

My history teacher essentially told the class that the US bombed Hiroshima and Nagasaki immediately after Pearl Harbor was attacked. She then used this misinformation to imply that the nukes were completely unnecessary.

Jr High. Modern American condoms were made of latex
or intestines. How friggin' romantic that must feel...

I call bullshit on the intestine condom idea. They tried to tell us about that in sex ed, but I know Tennis Racquet wires used to be made from cow intestines & that they'd fall apart if they got wet...

That would be because the strings are treated to a very special chemical cocktail that degrades in water.

Condoms were originally made from sheep intestines - and they still are.

For those who are allergic to latex, they make condoms from intestines to cover the latex intolerant.

I had a lot... Can't remember any off the top of my head, though.

Wait, so that wasn't inaccurate?! I've never typed "omfg" but OMFG! Prevent pregnancy by depositing male fluids (sorry mods, best I could think of at the moment) into the entrails of a dead animal?! No really, how the hell is that even remotely romantic or arousing to anyone? Hell, I'll even throw my faith in on this one and ask if this constitutes bestiality since an animal was used in the process of conducting the sexual act.

Maybe I'm looking at this wrong, but right now my mind has officially been blown.

About as romantic as it is to take care of a baby's pissing and pooping while you're still in school.

I think the one thing that once you're smart enough to call your teacher out on something, you should be smart enough to understand that teachers are just people, usually well-meaning people, but they have their limitations and misconceptions.

I learned to be critical at an early age because my grandfather's delight was to playfully teach us everything the wrong way (which is why I called hand feet and feet hands for a while). It engrains that every message is subjective. What I wish I had learned at a younger age is to deal more nicely and gracefully when I know someone is wrong instead of blasting it in their face or ignoring everything they say from that point on.

I've been in three high schools, and in every one, Global History consists only of Western Europe and America. Forget China, we have Britain. Ottoman Empire, forget those Islamics, let's learn about the American Revolution for a couple of months. :/

My citizenship teacher once said that the Pope was the head of the Church of England.

I would'nt mind so much except I was in a catholic school.

Health Class tacher, to a perfectly nice guy who liked to smoke weed on the weekends "You'll be dead in five years if you keep it up."

Not directly taught to me, but alot of Americans believe they won the war of 1812. Which is complete bullshit. If they had won, Canada wouldn't exist today.

went to catholic schools... i think that covers mot things

Damn, I can't remember specifics but I did once have a teacher who we had to correct a lot. We kinda stopped doing it though because she almost cried from being wrong so often. We ended up quietly figuring out what was right instead.

It's usually maths or physics lessons that teachers have to lie or "bend the truth" slightly so they don't confuse younger students. Like in year 8 physics when my teacher said there were only 3 states of matter. Lol.

Let's just say this: revisionist history is the only history taught in American schools. Seriously, it's freaking ridiculous.

Completely agreed.

Both sides in any conflict are whitewashed.

Rape of Nanking?
Never heard of it before!

What do you mean we marvelous Americans tossed Japanese folk into camps?
That's just absurd.

The first, it was the Japanese, unless you were implying something else. And for the second one, we read Farewell to Manzanar in 8th grade language arts, which if you didn't know is all about the internment camps. But I do agree that probably most of the U.S. has no idea that that ever happened.

I remember a random middle/ high school science teacher talking about how two objects cannot occupy the same space. At this point that statement has been amended to state that "No 2 same sized objects can occupy the same space at the same time" or something like that

I have a pretty awesome history teacher, she doesn't sugarcoat history, especially US history.
Although she claims to have studied under some martial arts grand master, and that she can use her "chi" to do all kinds of things.
she is secretly a Jedi who can use The Force

That water doesn't expand when it freezes

I know it was.
I was presenting an example for each side - the Japanese pretty much justified the use of nukes with what they did, and the Americans (or "we," if you prefer,) displayed MASSIVE hypocrisy with what they did.

When my Senior economics teacher tried convincing the class (including me, a Brit with a taste for rock music from the 1960's to 80's) that the Beatles were all American... It's at this point I requested a subject change (This is in Australia)

...

On topic, the biggest one would be that evidence of the Holocaust was questionable at best.

Yeah...

Ah, I see. I was a bit confused there.

My English teacher in year 6 said a good story had no speech in it.
I hated that teacher.

yo dawg i herd u liek confusion so i put some confusion on ur confusion so you could wtf while you wtf

It's alright.

That marijuana is a very deadly and dangerous drug, and is highly addictive.
That's kinda what it said in my science textbook in 8th grade. There are so many things wrong with the educational system, and some people are just not fit to be parents. The world needs change.

Most inaccurate thing I was told in school? Drugs are bad (m'kay).

Zac_Dai:
Wow the American education is pretty fucking terrible by the sounds of it.

I mean I had teachers who were arseholes, but at least they knew the subjects they were teaching.

My thoughts, too.

In my freshmen health class we were taught that if EVERYONE practiced abstinence their whole lives the world would automatically become a better place and worse of all i got a detention for asking how and offering the counter arguement that the human species would cease to exist if we followed that logic. The only answer i got was simply "God wouldn't let it happen". Damn bible-thumpers

That God would looks after us and love us all. HE'S NOT REAL YOU FOOL! *ahem*

Actually it was that eating glue was a bad thing, that paste tasted gorgeous.
