The major problem, is not spelling and grammar -- it's the theft of intellectual property. Many students, for whatever reason, think nothing of skipping the reading assignments and simply Googling/copying/pasting answers to graded assignments. Believe me -- I've debased my composition quality standards as much as I can while still being able to surmise the students' meaning; what I can't overlook is academic integrity in terms of presenting original work. I'm learning to accept that proprietary education (the schools for which I work) is, primarily, a source of a credential for employment. But it's hard to get past the need for some honest learning to take place. And that's what's taking up most of my time.
