Griping about students... AGAIN

I just did a lecture on control surveys and map projections for my surveying class. Consequently I also gave them a simple quiz on the subject. One of the questions was as you see below. All the images will grow when you click on them, and all my comments on the quiz papers are in green scrawling writing. Shall I weep? The class average was 48%

The question. You see, not too difficult I thought.

When in doubt... keep writing the words all over the place, surely one of them will land on the right item?

Interestingly, we didn't even talk about the poles during this lecture, they are left off the mathematical model because they get too distorted...

Equator? Of all the things to NOT remember? Equator? BLUEWICH? Funny, but really really sad.

Well, at least they got "equator" on this one...

The best right answer, with added bonus of being pretty. There were few of these "right" answers.

Why is it an 'ellipsoid', and not 'the earth'? Is zero degrees longitude on every ellipsoid or sphere called The Prime Meridian?

...and do they all run through Green-witch?

ellipsoid because that's what we were talking about in class that we use as a MODEL for earth... perhaps my giving quizzes on what we cover vs other stuff that we didn't talk about would yield equally comparable results?

I liked the "beautiful" comment

Bluewich made me laugh, and Green witch was also a good answer.

Henceforth I will refer to the equator as the Bluewich meridian. Now what should I rename the tropics . . .

Dawn said...

Ah, the attack of the Green witch!

I agree with cam. The equator just got a new name.

I also really enjoyed the student who redrew many of the lines of longitude to make them something else altogether.

And who is this miracle student who draws the earth?? That was crazy!
