Thanks to Richard Byrne for pointing out these new features. If you use forms for student assessment, you can now shuffle the question order, so students can't copy each others' answers (or memorize them!) You can also limit responses, so that people can't repeatedly fill in a form. I used Google forms last year in a March Madness book poll, and several students spent hours voting so their favorite books would win. At the time, I figured their passion deserved some recognition, but in the future, I'll be sure to limit responses.
