Submit Google Docs with a Google Form (Read warning)
WARNING: This creates a copy of the submissions and therefore does not allow you to leave feedback that students can see unless you individually share the documents with them.
Do not clutter your inbox by having students share their work with you! If you're not already using Google Classroom, consider using this as a way to organize student submission. Make the Gogole Form and share the link, collect submssions and start giving feedback.
