Teachers leave grading up to the computer
CNET News.com - April 7, 2005
A computer program developed at the University of Missouri may take some
of the tedium out of teaching--it grades papers and offers students
writing advice.
Ed Brent, professor of sociology at the Columbia, Mo., university, spent
six years developing the program, which is called Qualrus, and has been
testing it on his pupils for the past two. It works by scanning text
for keywords, phrases and language patterns. Students load papers
directly into the system via the Web and get nearly instant feedback.
How can a cold, mechanical computer comprehend the art and nuance of
writing? The program is actually quite sophisticated, Brent said. It's
not enough to just throw keywords into an essay willy-nilly. The
program analyzes sentence and paragraph structure and can ascertain the
flow of arguments and ideas. It gives each work a numeric score based on
the weight instructors place on various elements of the assignment.
