years ago, a friend of mine (then teaching chemistry) failed a student for a poorly presented answer on chemisty lab reports

his attitude was this was perfectly valid, well written lab reports made the science clear, (and would allow other to verify the results. he maintained English classes existed exclusively to teach grammer so students could write clear and concise lab reports... (the english department was thrilled with this idea, but.. they backed up him and when the student appealed to the english department!)
