There are many sites and extensions that allow students to create citations, most with little work from the students. QuickCite actually requires students to enter the information before it is cited.
The information required for either Quick Attributions or MLA 8 gets the students to do much of the work for themselves.
If they aren't sure what each category is asking, there are helpful popup boxes located next to each field that explains what is needed.
Another nice benefit is QuickCite doesn't require an account or sign in.
