I set the timer and focus on my new goal: to grade a paper in twenty minutes. Everything starts smoothly; checkmark after checkmark, praise after praise. A quick glance at the rest of the paper reveals more of the same error-free, polished style. Hmm. I pull up the student’s writing diagnostic, previous assignments, and emails. All are riddled with errors and awkward phrasing. The plagiarism report, though, comes up clean.
