We had computer classes where we had to learn about spreadsheets.
To do a number plus ten percent we had to put in A1+A1*10/100
I did A1*1.1 like a normal person.
She then went round to make sure everyone had put it in correctly. Got annoyed at me and changed A1 to something else to expose my folly.
Was visibly annoyed when it showed the right answer.
(I don’t think taht was your teachers point at all, but) couldn’t the fifferent formulas produced different rounding errors due to floating point percision?
Man… This sucks. I can’t believe how many lemmings have had similar experiences. I’m just remembering one now where I was excited about math, went ahead in the curriculum to fractions, and answered everything in ratios. Instead of the teacher seeing the simple mistake, I just remember them being “wrong”. How deflating.
Kids need connection before correction. I’m sort of glad my kid is glued to a screen doing adaptive math. It sucks in its own way, but better than unfeeling correction. Though, at least in my district, there’s a big emphasis on empathy development so I think the teachers try to model that.
Americanized versioned, but with a match teacher it went something like this:
Teacher: Whoever can solve this will get an A.
me: I have a solution.
Teacher: come out and explain it.
Me: I do just that.
Teacher: that is correct, but you didn’t use the method we just learned, no A, sit down.
There’s not much worse as a kid in a learning environment, or even with your parent(s), to be shut down painfully for being right about something that they don’t know or don’t think you know. Really crushes the satisfaction of nailing a win and turns it into bitterness and starts the lifelong process of keeping your mouth shut when you’re right and letting others win when wrong.
On the other hand, its a crash course in reality of just because you’re right it doesn’t mean anyone gives a shit
Never stop fighting their lies
I had a kindergarten teacher try teaching syllables by clapping them out while saying the word: 👏 ALL 👏 I 👏 GATOR! Alligator! 👏 ALL 👏 I 👏 GATOR! Three syllables.
Tried correcting her, she just clapped and said gator again.
I still remember my teacher bitching me out in front of the class when we were learning negative numbers because when he asked me how I figured out the correct answer I said that the positive numbers and negatives cancelled each other out. Like -4 and positive 5, the negative 4 cancels out 4 on the positive side and you are left with 1. Maybe that wasn’t the correct verbiage but it gave me the correct answer every time. He was a dick about correcting me though.
“youre not supposed to know that yet” then why in fucks name did you ask lady?
God that teachers dumb… Why even as the question? Why not just do 20 - 20 if you are going to be upset when a kid knows the answer. Simple! Don’t ask questions you don’t want the correct answers to. Teaching kids the wrong answers only messes them up the next year when they have to unlearn the bullshit you taught them.
Fucking hell I feel validated rn, I had a similar experience at that age but it was in language/reading class. It’s so frustrating to know that you are correct but you lack the terminology/ability to properly convey why you are right.
This shit happened to me, but in kindergarten. I grew up in a bilingual house. I spoke English and Spanish equally. I went to the school with my mom to get assessed. She said I could read and was bilingual. The teacher didn’t believe it and made me read from one of their books.
To add insult to injury, when they had Spanish class, the fucking teacher taught us that “purple” was “porpuda” and “lizard” wad “lizardo.” Shit like that… My mom put me in another school.
I’m 48 and still laugh about lizardo. How absolutely stupid.
Was your spanish teacher called Senór Chang by chance?
El lizardo is a great name for a male strip club tho!
You had Peggy Hill as a full time Spanish teacher‽‽ She’s supposed to be a substitute!
To add insult to injury, when they had Spanish class, the fucking teacher taught us that “purple” was “porpuda” and “lizard” wad “lizardo.”
That’s ridiculous! Everyone knows the correct world is lizarda! Spanish is a gendered language, the genders matter! /s
When I was in kindergarten, my mom got a call day 1 because I didn’t know how to count to 10 supposedly. Even though I did it multiple times. I just did it in Japanese cause they never requested I do it in English. Tbf, I’m white and not bilingual.
Lol my ex girlfriend had a “karate” teacher growing up. He taught them a few “Japanese” phrases. It wasn’t until decades later she learned this dude just made it all up. I guess it was something you could get away with in early 90’s bumfuck Wisconsin. Like this dude just rolled into town, started “karate” classes, and just kinda went with it.
Thanks, now I have a plan for trolling my kid’s future kindergarten teacher.
why does this gat dang kid keep complaining about his itchy knee?!?
san yon go roku shichi hachi kyu jyu!
…jyu-ichi jyu-ni jyu-san…
Ok I’ll stop now.
Ahem, not bilingual, but I definitely have a small chunk of Japanese drilled into my head after a decade + of Karate, haha.
Okay…
lol porpuda. was she trying to say púrpura instead of morado?
y más lagarto = lagardo = lazardo = lizardo??
poor kid
Exactly that. Porpuda is now a joke between my girlfriend and I and we intentionally use it wrong.
I had an elementary school teacher who insisted that gravity came from the earth’s rotation, and that if the earth stopped spinning there would be nothing holding us down.
I had a math teacher at my stem highschool claim that the touch screens on the ipads worked by heat and that if you touch them too much the screen will get too warm and stop responding
She also told students their computer was slow because they had too many desktop shortcuts, or hadn’t emptied their “trash” files.
There was also an argument we had over whether something was actually a 3d vector or multiple 2d vectors but I don’t wanna dredge my memories for the exact details, it was dumb.
So, there is some jank in how Microsoft handles the desktop that results in more shortcuts on in using more resources. It always has to have all the images and icons loaded at all times.
But with the increases in baseline RAM I’d be shocked to find anyone with more than 4GB experiencing slowdown from it, even in the most extreme situations.
Similar thing with trash/recycling bin. Are you already low on storage space? Then yeah, clean it so your PC has enough spare space to work, or to use for swap (effectively extra, slower RAM by way of using drive space). But that was also far more likely to be a problem on the old drives measured in MB.
Huh, thank you for the additional info!

I think the only way this could be any stupider is if she said it has cameras under the screen looking for where your fingers go.
Lol, yeah somehow that would sink even lower. It fucking drove me up the wall when I was a kid
I had an 8th grade social studies teacher/football coach tell us black people had an extra bone in their leg and that’s why they were so good at sports. He was pretty well liked teacher tbh, we watched Oliver Stones “JFK” in his class. During lectures he’d come around and sit on the front of his desk to seem more relatable. He ended up on the school board eventually.
Did your teacher believe in the hollow Earth theory?
Average autism experience tbh
Yep, am autistic, can confirm.
As with Union of Kobolds, I eventually got into the ‘gifted’ program… they even had me as a 2nd and 3rd grader basically being an unpaid tutor for 4th and 5th graders, sitting in the hallway, helping kids with reading difficulties (in all liklihood, undiagnosed dyslexia) read through kids books.
But, there’s always classes and teachers not part of the gifted program, and they’re often difficult and wrong and rude for no reason.
I still remember a chemistry teacher getting very angry with me for even bringing up quantum scale electron clouds as a model of atoms.
Not allowed to go beyond the Rutherford-Bohr model, even in discussion, always dismissive and rude, incapable of saying just ‘yes that is a more accurate model, but it is far too complex to go over without understanding Rutherford-Bohr first’.
That, and teachers really fucking hate being called out on something for some reason.
All my teachers were fine with it honestly :3 at least after primary school… if you corrected them they might’ve given you extra credit
But the general notion of saying something correct and people saying that that’s wrong, and not knowing why still stands
I asked my science teacher why and how the periodic table was setup like it was, I got “that’s how it’s setup”
But why, there as to be a reason
That’s just the way they made it
Yeah because they have to have gone by something what is that something
That’s just the way they did, stop asking questions (please don’t fucking learn in here)
Godamn that pissed me off.
Really? We got a detailed breakdown of why the periodic table is the way it is
Yeah, turned me off to science at that age too which sucks because I was pretty into it.
Once I got into Gifted teachers were like that. My first couple years in normie classes suuuucked.
Then in Gifted the bullies got much smarter. Fun times.
Really? Seems like.a very shit teacher and school. Dont think a 7 yr old getting upset by that is unusual. Id be furious of that had happened to my kid.
Its kind of a perfect example of how mediocre has become acceptable and even celebrated. And the attidues of don’t question, or don’t challenge. Scale that up and you start understanding how the world is as it is, particularly in the US.
They need you to feel like less so they can feel like more. Their comfort trumps your reality. Bystanders are more comfortable appeasing bullies than caring for victims.
“Impossible” would be a more mathematically accurate answer than “zero”.
It’s not a matter of accuracy even, if for any two natural numbers x < y it holds x - y = 0 then x = y, which is a contradiction. So this is basic consistency requirement, basically sabotaging any effort to teach kids math.
Depends on how your mathematical system is defined. In the mathematics system this teacher is using, negative numbers simply do not exist. The answer to 5-6 is the same as 5/0: NaN. Is this mathematical system incomplete? Yes. But, as has been thoroughly proven, there is no such thing as a complete mathematical system.
The answer would still not be 0 as 0 is clearly still well defined within that system. NaN, undefined, etc. would be acceptable answers though. Otherwise you define:
for x > y, y - x = 0
Which defines that x = y
Resulting in the conditional x > y no longer being true
Also x/0 isn’t NaN. It’s just poorly defined and so in computing will often return “NaN” because what the answer is depends on the numbering system used and accidentally switching/conflating numbering systems is a very easy way to create a mathmatical fallacy like the one above.
Yea, or “the first twenty are free but the remaining five you don’t have to give are a problem”.
The worst part is that he was grounded by the parents. When I was younger a teacher told me I was wrong for saying that Portrush was in County Antrim, not Londonderry like she told the class. My mum brought it up at the parent teacher conference.
Same teacher also marked me wrong when asked to list loughs in Northern Ireland and Iisted Lough Beg. I was right, but it wasn’t on the list that SHE gave us.
I really don’t get this attitude. I’ve taught many classes, and making mistakes is just part of teaching. Unless you’re just reading from a textbook (and even those can be wrong), you’re going to make some mistakes. I’m a human being; sometimes I’m going to get stuff wrong. I try to minimize the errors, and it’s not like I’m teaching subjects I’m unqualified to teach. But to err is human. Maybe it’s different because I’ve taught undergrad students rather than K12, but IDK. I just really don’t get the attitude of an educator that feels they need to conjure up an aura of unerring perfection.
if I make a mistake in some derivation, I’ll just admit it, usually with some self-deprecating humor. A few things I’ve said to address it when it happens:
“Whoops! Guess the coffee hasn’t kicked in yet!”
“Whelp, contrary to popular opinion, I am not infallible!”
“Well, I’m clearly not infallible, guess I’ll never be pope!”
<Delivered with obvious sarcasm.> "No, you see, that was intentional! i was just testing you to see if you would notice my error! Obviously it can’t be that I made a mistake!’
“Whelp, as you can plainly see, I am clearly drunk!”
I’ve said all these and other things in front of entire classrooms of students. I don’t make mistakes often. But if you teach enough, it does happen. And it’s always a bit annoying to the students, as they have to back up, maybe correct their notes, etc. And I try to lighten that annoyance with some levity. So I try to make my lectures as correct as possible. But when mistakes do happen, i just try not to make a big deal about them, I dismiss them with some light humor.
Honestly, I’m glad I make mistakes. I wouldn’t want to teach if I didn’t. Part of teaching is making students feel confident that they have the ability to wrap their heads around concepts that may be very challenging. And if even the instructor can make mistakes? Well then students hopefully won’t feel so frustrated and demoralized about the ones they make.
It’s a fine line to walk while teaching. On the one hand, you want to be an authoritative source of knowledge on whatever topic you’re teaching. On the other, you need to be human. And part of that is not trying to portray yourself as some infallible god. Because ultimately that’s not what you are. And kids are clever and perceptive; they can see through your bullshit. If you make a mistake and try to cover it up, they will see through it, and they will lose respect for you. Aside from a few reprobates, most kids have enough emotional intelligence to realize that ultimately you’re just a human being trying to do your best, and that some errors are inevitable. Students are perfectly willing to forgive imperfection. They’re far less willing to forgive dishonesty.
