30 Students And Parents Call Out Their Teachers Who Were So Wrong, They Shouldn’t Be Teaching Anyone

I had a teacher try to tell the class that Saturn, Neptune, and Uranus were the only planets known to have rings. I raised my hand and added that Jupiter had rings too, but that they were so faint they were hard to see. She vehemently denied it. When I politely (yes, really) told her that I had just seen it in a book, she gave me detention for trying to correct her in front of the class.

The next day, before class began, she approached me with an encyclopedia opened to a page about Jupiter, and apologized. She told the class I was indeed right, and that it's important to listen and learn from people even when we think we are 100% right. One of the more wholesome moments I can remember from school in my youth.

That if I didn’t learn my times tables I’d wind up a broke garbage man, never learned then but I’m a garbage man who made 6 figures last year

Sex ed teacher in grade 7 told me that the white stuff that collects in my underwear is semen. I’m a girl.

I learned way later that it’s actually discharge and EVERY vagina does this.

That I won’t always have a calculator in my pocket. F****n liar.

My name's pronunciation. 1st grade 1st day of the year we all told our names, introductions etc. My name is from a SEA country and not even that difficult to say just read differently than its spelled, its even monosyllable. My teacher screeched at me and told me it'll be pronounced the way its phonetically spelled in English which included swapping two middle letters for some reason. The other students went along with it and so did I. Even to this day I still introduce myself by that pronunciation except to people of my own race.

In university I started getting people that wanted to pronounce it correctly which was incredibly kind and they sort of pointed out how messed up it was for that teacher to decide that for me.

People are going to offer you drugs disguised as candy at the park.. Just say no!

20 years later and I still haven’t been offered drugs at the park.

"You shouldn't write 'Xmas' instead of 'Christmas' because you're X-ing out Christ."

The X is really the Greek letter Chi, which is the first letter in the Greek word for Christ.

My mom told her 1st grade teacher her favorite color was magenta. Her teacher punished her for not picking a real color, and for arguing with her about it. My great-grandma, a painter, sent my mom to school the next day with a tube of magenta paint! Not long after this my mom skipped to the second grade😂

1st grade math

Teacher: what's 2-1

Class: 1

Teacher: What about 1-2

Class: confused

Teacher: See, you can't subtract a smaller number from a bugger number

Me, an intellectual: Hey, wait a minute, that's negative 1

Teacher: Shush, those don't exist til third grade

That I could avoid a nuclear blast by hiding beneath my school desk.

Silly woman. I saw a movie about this, and now I know to climb into a refrigerator instead.

A student in my class asked why we call it the 20th century when the year was 19xx. The teacher explained that most likely that a long time ago probably in the dark ages they made a mistake in printing a calendar, but by the time it was noticed all the calendars had been made and sent out, so they just left it that way.

I heard her say this and knew it was all kinds of bull s**t, but I said nothing because I was a shy 4th grader and she was a hostile nun.

That the moon emits light, just like the sun. As a nerdy kid interested in space I told her that it’s actually reflecting the light of the sun, but she did not believe me.

Never forget it. In 4th grade we were learning about bats. And the teacher asked the class to name as many different types of bats as we could. I raised my hand and said "Vampire Bats," and he said name only real ones please.

They are real, and I knew it. But he made me feel like an a*s.

6th Grade

Me: But what happens when you subtract a negative number *from* a negative number

Teacher: You...can't do that

That I couldn't have blue eyes if my mom had brown eyes. Thus began a life long obsession with genetics so I could prove her an absolute f*****g fool. Bless my mom's single recessive gene she passed to me. I missed the blonde but I'll take the blue eyes.

Science teacher in 4th grade told us it takes food 45 minutes to get to your stomach after swallowing. Spent an entire class period on it.

He handed us each a piece of cereal to eat at the beginning of class. Halfway through (some 20 minutes later), we had to point to where it likely was in our system. The correct answer, according to him, was somewhere right above our collarbone.

Years later, a bite of too-hot oatmeal told me he was an idiot in all of about four seconds.

I got sent to the principal's office for using the word "plethora." The teacher thought it was a swear word. So did the principal.

EDIT: For those asking about a dictionary, yes, they looked it up. And there is some obscure, arcane definition that means a swelling of a body part. This, of course, is the only definition my teacher knew, not the extremely common one.

That there was no such thing as a black flower. She put a big X through my painting.

That Lincoln was the first American president. I told her she was wrong, it was Washington, and she snapped, saying ‘well why do you know so much about American politics it is pathetic.’ And all the other kids in my class started making fun of me for being stupid.

Reasons why I hate rural Canada.

Not a teacher but the principal. When I reported one of the school bullies for physically attacking me (plenty of obvious proof), he put the blame on ME, & told me to "grow up". Spineless worm!
