This reminds me of a much more reasonable bad teacher from my childhood, which I still remember as unfair

We had been learning the vowels, which in one thing were listed as a, e, i, o, u, and sometimes y, among others with the just the five most common ones

So days later when we had a quiz my answer to which letters are vowels was a, e, i, o, u, and sometimes y. I got a red x, with "and sometimes y" crossed out. I don't think we were given points but it felt like zero points.

I wonder if this is an actual child being taught not to trust questions or someone implementing the idea of get internet points by typing a question, writing a childlike a correct answer, then writing in pen a bad teacher response

When I was in elementary, my teacher said that "Lutetia" was how the Romans called the city of Liege. As an avid reader of Asterix comics, I knew this isn't true and corrected her and said it was the Roman name of Paris. She insisted that it is Liege. Anyway, the next day, she came back to class and said that she looked it up and that I was indeed correct and Lutetia referred to Paris and gave me a chocolate bar and told me to keep reading comics. Good teacher.

In elementary school our teacher asked us to spell the current year with roman numerals, so I worked out "MCMXCVIII", which I was quite proud of. But the teacher came back at me quite snarkyly and said it's much easier to just substract 2 from 2000, "IIMM" duh!

It was only many years later that I accidently learned that he was indeed full of shit and I was right all along.

[–] Kazumara@discuss.tchncs.de 40 points 1 week ago (2 children)

it’s much easier to just substract 2 from 2000, “IIMM” duh!

For anyone wondering why this is wrong, there are two reasons:

  1. The roman numeral system only traditionally contains subtractions from the next higher five- and tenfold symbol. So you can subtract I from V and X, X from L and C, C from D and M

  2. The subtractions only generally allowed one symbol to be subtracted, with a few notable exceptions like XIIX for 18 and XXIIX for 28

I had a HS teacher say the the 2nd to 5th richest people were the Walton(of Walmart) family heirs. I knew this wasn't right because at the time, Steve Balmer(of Microsoft) was the 5th or something. I printed out the Forbes list and brought it in. The teacher coped by saying that if you combined the Walton wealth, it would rank that high. He was a POS teacher for more significant reasons than that though.

I once got in trouble with my math teacher for saying "well if we're just making things up, then sure [I cheated on a math test while sitting in the front of class where the teacher can see but I was using some kind of hidden code on my t-shirt that was a bunch of Shakespearean insults] . But what about all that Crack you were doing in your car this morning?"

Apparently my "making things up"was a slightly more serious than his. I stand by it. If we're making shit up, we're making shit up.

For the record, this geometry teacher was convinced I was cheating in class because I didn't do homework. Homework was 5% of the final grade for the year according to his syllabus, I hated homework, so I figured as long as I didn't suck at the rest of the class, I could do 0 homework and pass. I was right, passed with a 94%

Why would you ask "How is this possible" when you expect the answer to be "it's not"?

[–] kkj@lemmy.dbzer0.com 99 points 1 week ago (2 children)

Teacher got the worksheet from someone else and didn't know the answer.

The teacher is fucking stupid. The question says Marty ate more, that is not only possible it is a given.

[–] UnderpantsWeevil@lemmy.world 83 points 1 week ago (4 children)

The teacher is fucking stupid.

The teacher is likely under-trained, overworked, and under-qualified for the class. Common in districts where the focus of the administration is driving down the cost of education rather than delivering the highest quality.

That is, of course, assuming this is a real homework and not some agitprop churned out by a Facebook group or a social media account more interested in generating outrage than education.

[–] Irelephant@lemm.ee 43 points 1 week ago (3 children)

With the choice of marker, I'd say its rage bait.

Take that to the principal, stupid teachers shouldn't teach

[–] remon@ani.social 70 points 1 week ago* (last edited 1 week ago) (2 children)

Reminds me of the time when I got send to the principle for saying "fuck you" during class. I was saying it to a classmate, but the teacher felt it was directed at her.

Anyway, the principle (herself a German teacher, this happend in Germany) gave me detention and wrote a letter to my parents, saying it was because I made a sexist remark towards a teacher.

My Dad wrote back explaining the difference between a sexist and an obscene remark. They canceled my detention and I never heard about it again.

If you state that Marty ate more as part of the question, you cannot answer in any other way, because it denies mathematical logic here. You introduced a lie as part of the problem, and if I need to decide myself which part of the statement is a lie, I can pick whatever I want, let's say, Marty didn't ate 4/6, but 6/6. This teacher should be taken to the gulag.

It is entirely possible and his answer was correct. Question was phrased incorrectly, if the teacher wanted an answer "it is not possible" he should have said both pizzas were the same size.

The teacher is the one who's confused here. The kid is entirely correct.

[–] conditional_soup@lemm.ee 56 points 1 week ago* (last edited 1 week ago) (4 children)

I... Um... I've been looking at this for a minute and I can't tell why the answer is unconventional, nor what the fuck the teacher is on about.

[–] Freshparsnip@lemm.ee 41 points 1 week ago

The kid answered correctly, it's not unconventional at all, the teacher is just stupid

[–] King3d@lemmy.world 33 points 1 week ago (3 children)

It’s fucking dumb. No where did it say the pizzas are equal size. So the kids answer is just as right as her bullshit answer.

[–] lunarul@lemmy.world 39 points 1 week ago (1 children)

No, the kid's answer is not "just as right", it is the correct and expected answer. The teacher's answer is wrong and proof the teacher doesn't understand the question. The entire point of the question is understanding that fractions of a whole are relative to that whole and you can't directly compare fractions from different wholes like that. 5/6 > 4/6 doesn't mean Luis ate more pizza than Marty, it means Luis ate a larger share of his pizza than Marty ate out of his own.

But... The teacher is just flat-out wrong. It says right there in the problem that Marty ate more, and then uses that fact as a foundation for the question of "x is true, HOW can x be true". It'd be different if the question was "someone claims x is true; is it?"

Given 4/6 x > 5/6 y therefore x > 5/4 y

Marty's Pizza must have been more than a quarter larger than Luis'. The kid is exactly right.

And the teacher is not flexible enough to engage outside their expectations for how the question was supposed to be answered.

Clearly the expectation was for the kids to take the unstated assumption that the two pizzas were of the same size, and reject the premise as unreasonable (note the heading "Reasonableness").

Teachers that don't accept an unexpected but true answer are not teaching. The test taker had a correct take, one of the pizzas could be bigger than the other. It was not specified in the question. I am so glad I am out of school

i can't fathom this being real, most probably this was made for karma farming or something.

[–] edgesmash@lemmy.world 25 points 1 week ago (10 children)

Teachers like this exist. One of my kids had an elementary school teacher like this. Two examples:

  1. The math assignment was about currency denominations; what coins and bills you need to make up $7.42, for example. My kid answered using $2 bills (uncommon in the US but still printed), as we have them at home. Teacher marked the answer wrong because teacher didn't mention $2 bills in class.
  2. The writing assignment was to rewrite the Snow White story from the perspective of another character. My kid, having read a bunch of those "twisted tales" and recently fallen in love with "Wicked", wrote from the evil queen's perspective and made her a sympathetic character. Teacher marked her down for "changing the story" without acknowledging my kid's creativity. Teacher did not back down when we confronted her on this during our parent teacher conference.

(FWIW, in both cases we reassured our kid that they did great in both cases, and that we were proud of them.)

This brings back memories of when I realized that I was smarter than most of my teachers.

[–] leadore@lemmy.world 35 points 1 week ago* (last edited 1 week ago) (3 children)

This is bizarre. The info provided in the question was that Marty ate more than Luis, the question was how would that be possible given that Marty ate 4/6 of his while Luis ate 5/6 of his. The answer the kid wrote (Marty's pizza was bigger than Luis') is the only possible correct answer.

The grader is asserting that the information given in the question was wrong and that "actually it was Luis who ate more pizza"--even though it stated as a premise that "Marty ate more". How are you supposed to give a correct answer on a test if you are expected to accept one premise (proportion of pizzas eaten) while disregarding another premise (Marty ate more than Luis)? How do you decide which part to disregard? Would they have accepted the answer, "Luis actually only ate 3/6 of his pizza, not 5/6)"? Wouldn't that be just as valid an answer as "Marty actually didn't eat more than Luis"?

Some real "steel is heavier than feathers" energy coming off this teacher.

[–] vala@lemmy.world 31 points 1 week ago* (last edited 1 week ago) (7 children)

"This is not possible because..."

This kid is never going to trust teachers again.

He was right. The question is not even worded ambiguously. It was just written very poorly.

Will the teacher admit that? Or is the expectation that this (likely neuro divergent) student should have just understood the expectations based on context clues or something?

The title of this post is disappointing. The given answer is sound and it seems safe to assume it was arrived at by thinking mathematically.

I suspect many commenters are missing the point, the student's response can only be the correct and expected answer to this question. Teacher has it wrong.
