OCR paper grading
OCR of school papers to automatically enter grades into a database.
At Quora I read that a Junior high school the teacher
spent more time entering grades into an application than
actually grading the papers. They had saved up 600 of
them for a data-entry session.
This suggested the obvious OCR (optical character
recognition) of graded papers and their entry
A fun casual approach would be an OCR pen that
interpreted the written scoring, perhaps preceded with a
circle around the student's name. OCR pens already
Another approach could be just loading a stack of graded
papers into an OCR with a sheet feeder.
Less obvious would be OCR glasses that merely gazed at
the papers while the instructor wrote on them.
While really obvious there are millions of teachers
worldwide that might welcome an OCR approach.
||[+] Anything to limit the overhead and helping systems to a realistic intrusion on actual work time. the solution has to work and be less time intensive.
||Back in Korea (South) my colleagues ended up with a
bazillion test papers with "tick the correct box" forms.
||Stupidly I remembered about halfway through their
marking that they could do a template with bits cut
out over the correct answer, save all that time totting
up points. Education is just another factory.
||Why do they write the grade on the paper rather than typing it in
as soon as they've decided it? (Actually, why do they read the
writing on paper at all?) They could even type in a mark for each
aspect of the work and the computer could automatically
compute the overall grade according to the rubric.
||Alternatively to OCR, just use a smartpen that's capable of
tracking on mundane paper (perhaps using an IMU or special
writing pad), or put the paper on a graphics tablet and use its
stylus (but then you don't get ink on the paper and so can't see
what you're writing, so there's really no point in putting the
paper on top of the tablet).
