Mar 21, 2017 at 12:32 comment added Lawrence Yes, that question can be asked in an incredulous tone, in which case it would be similar to "Hasn't a student used this previously?".

Mar 21, 2017 at 11:37 comment added Teacher KSHuang Yes, you are correct and stangdon is more precise.
Mar 21, 2017 at 11:29 comment added stangdon The statement version is "No student has used this previously." Does that help you understand the meaning of the question?
