[Phys-l] docking for correct thinking



On another list a teacher wrote:

On a related note, I had 2 students come up to complain about the points I deducted from their lab because they had massed a billiard ball and reported it as 1.58 kg instead of 0.158. They lost points for the error and in a few places where they used the erroneous mass to come to wrong conclusions.


Am I legitimately concerned about the punishment for the allegedly wrong conclusion(s)?

Here's what I wrote in response: (not yet posted -- "discretion")


I'm w/ them; their conclusion(s) wasn't (were't) wrong.

bc wonders, if they'd concluded what you think is correct even w/ the 10X error, Dan woulda not docked them?

p.s. I am concerned about this. You've docked them for "correct" thinking, not a good message.


bc wonders if he's off the deep end.

p.s. one of the few things I remember from my HS physics (elite private school) is, if an error made early, no further docking if the remaining is all carried out correctly. (consistently)
