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 …

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 …

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

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

> Precision and accuracy have different and distinct meanings in engineering. is there something I said that gives you the impression that I need this explained to me ?
