      7/ So if your answer is "lol, derp, stupid teacher, stupid schools, how dare they mark the kid down for giving a more precise / more accurate answer", then you don't understand the real world, or trade offs between computation time and accuracy, or budgets, or schedules.

      8/ perhaps on the part of the page that's cropped from the meme? or perhaps it was explained by the teacher if the lesson was on fractions and a kid used a calculator to reduce 1/3 to 0.333333333333333 would you complain that it wasn't spelled out?https://twitter.com/binarybits/status/1128757146978529281 …

      Where does the question say "use the process known as estimation?"

      9/ we have visual evidence that the teacher is doing this, but the objection is "the teacher isn't doing this" /shrug okhttps://twitter.com/wraithburn/status/1128757519835332610 …

      I don't disagree, but the context is that the school teachers AREN'T DOING THIS. They don't actually teach this idea, they mark you down as failing because the "show your work step" is not identical to the one in the book. No learning happened.

      ⓘ Dogs don't have thumbs Retweeted Challenger

      10/ More on the "estimation" thread. Many people respond with some example like this:https://twitter.com/PulseAwakening/status/1128987934026108929 …

      FWIW my take on it, from the kid's point of view, is: Madam, if you wish me to estimate things, don't give me inputs that are faster for me to mentally calculate than to estimate.

      11/ Basically "if you want someone to follow the lesson plan, you need to make it harder to cheat". Why? The lesson is there to teach how to estimate. I might have a lesson that says "react X hydrogen with Y oxygen". Writing down "water!" when the point is labwork is WRONG.

      12/ If the kid wants to ignore the lesson and fail to learn proper labwork, or proper estimation technique, fine. The teacher's job is to: 1) teach the method 2) test the learning 3) provide feedback if #2 is defective

      13/ The most common (dumb) response was "the question didn't say 'estimate' ". (a) the question was #9. To argue 'but the question didn't say 'estimate' is to implicitly assert full knowledge of the entire quiz -including title at the top, which might very well be 'Estimating'

      14/ Even if the quiz doesn't say 'estimating' across the top, context matters. If the last week was teaching reverse polish notation on an engineering calculator, then the correct answer is "I punched 28, then 103, then plus key". If context is 'estimating'...

      15/ Another dumb response is 'but the kid's answer was BETTER'. No, it wasn't. Utility in the real world is not measured on a single scale. Time, effort, correctness all matter, and the exact balance depends on the situation.

      16/ An alternate version: 'the kid's answer was more PRECISE'. Yes. And? Precision in excess of constraints is actually an error. If I give you a thermometer and tell you that it's accurate to +/- 2 degrees, then ask for the average of three readings, 91.0912854 is WRONG

      17/ I got told by one or two people that there is ONE CORRECT WAY to estimate, and that is to round numbers in a certain way. This is hilarious. Who taught you that there's ONE CORRECT way? God? There are dozens if not hundreds of equally valid approaches.

          18/ Many people wanted to argue "but I could choose a better example than the numbers the teacher chose". Sure. Me too. So what? That has zero bearing on the point.

          19/ "Herp, Derp, Common Core, Vaccines, Gay Frogs, Obama" was bandied about. FOCUS PEOPLE None of that matters. The topic was "is the teacher a retard for giving -1 points?". No, she's not.

          20/ One response was "the teachers are teaching the children to do math intentionally incorrect, and that's because they hate Truth, and Jesus is coming for them". As far as I can tell, this was serious.

          21/ I'm not sure what to say about this. ...but I imagine that every single Cathedral and church that has ever been built to glorify Jesus had 20 or 30 contractors using estimation to figure out how many tons of steel or ox carts of bricks were required.

          22/ As far as I can tell, Jesus has no precision on the accuracy with which floating point math should be done. The machine elves might, but Jesus doesn't.

          23/ Another response I got several times was "the question asked 'is this a reasonable answer' and the kid answered 'yes', so he got the question right !!" The question was two parts: boolean, then 'explain'. The kid used the wrong method in part 2.

          24/ There were multiple people who said "I can't imagine a single reason why XYZ" This is argument from ignorance. The fact that you can not imagine it is not proof of anything aside from your limited imagination. Pro tip: if you ever are tempted to say that, ask instead >>>

          26/ Then, of course, there was the person who got upset when I said that it was an argument by ignorance by being offended that I was calling him ignorance. (a) it's a phrase ("by" is not as common as "from", but is still common) (b) even if it wasn't, it was truthful

          27/ I challenged several folks who said "it doesn't say estimate" to tell me what the instructions at the top of the page were. All responded "I can't see the top, so I'm going on what I can see". This ... ah... Look, if you're saying the teacher is an idiot, then >

          28/ You're implicitly arguing "there is NO context in which the teacher's mark down is valid". In which case, saying "I can't see the context" is not a defense of your position. In that case you have to somehow enumerate every single possible context and disprove them all.

          29/ Several people called me dumb or derp. Which is ... surprising. If my argument has a flaw, point to the flaw in the argument. If you can't see a flaw, ad hominems do not seem useful.
