So, I was at the store last night looking at getting
a new scanner,
when a capability of HP all-in-one machines caught
my eye. Seems you
can plug in a smart media card from a digital camera
and they'll print
out a contact sheet with bubbles for each thumbnail
image. You then
bubble in the ones you want copies of, lay the sheet
on the scanner
top, and, presto, it prints out the photos you want.
So, I'm thinking, if they can do that, why can't I
make my own bubble
sheets and scan them in, and have some software tell
me the students'
answers to each of the questions?
The scantron machine we have at my school will only
grade tests, it
won't let you do an item analysis or anything useful
like figuring out
what students know and what they don't, and machines
that will do such
things cost major bucks.
So, does anybody know of an open source (or cheap)
that will read bubble sheets? If not, maybe I have a
project for my
Special Topics in Computer Science class next
