Teachers put to test by digital cheats

John Keilman:

Heloise Pechan’s heart rose when she read the essay one of her students, a seemingly uninterested high school sophomore, had turned in for a class assignment on “To Kill a Mockingbird.” The paper was clear, logical and well written — a sign, she thought, that she had gotten through to the boy.
Her elation passed quickly. What came next was suspicion.
Pechan, then substitute teaching at a McHenry County high school, went to Google, typed the paper’s first sentence (“Kind and understanding, strict but fair, Atticus Finch embodies everything that a father should be”) and there it was: The entire essay had been lifted from an online paper mill.
“I went from amazement and excitement to ‘Oh my God’ in the space of a half-second,” Pechan recalled.
