Please help with plagiarism checker

[marvin100]

But what’s more confusing me is–why would a student need to turn their paper in to a plagiarism-checker independent of submitting to class? The student should know what constitutes plagiarism and if they are doing it or not, right?

I agree with this. I can’t for the life of me figure out why an honest student who understands academic integrity would have to wonder if she plagiarized or not.
