About 40 years ago I was, as new lecturer in a college, confronted with a class of Police Cadets who were expected to do C&G Proficiency in Arithmetic ... I drew chalk marks on the road outside - got them measure the "tyre marks" and substitute into a formula... The result? A cadet, when asked, said, "The Mini in question was doing 172mph when the brakes were applied" - questioned, he stuck to his guns: "I done it on my calculator"
Yes, I've had that with a graduate we took on. Asked him to give me a rough idea of the volume of a fuel tank. I went off and did something else, and was a bit surprised an hour later when I cam back and he was still working on it. (this being a cubic fuel tank)! Eventually, he came back and told me it was 8.2154 litres.
"Bobbins!" I said (or something very like it)!
He absolutely stuck to his guns!!! Went through all the calculations again on his calculator (making the same mistake) and showed me the result to even more decimal places.
I asked him, if I fiilled it with beer, how long it would take him to drink it and he obviously had an intuitive idea of the volume, because he said he'd be able to swim in it, never mind drink it. I then asked if he thought he'd be able to swim in 8 litres of
anything and it seemed that there was just a fundamental lack of an understanding of how big a litre was, coupled to the (these days customary) unshakeable faith in the calculator - mainly because you get the answer to a lot of decimal palces.
(it was 80-odd litres, by the way)!
