Like with any tool that gives students more freedom, there is potential for bad behavior as well. We recommend setting the appropriate expectations with students.
Use this Classroom Expectations template as a guide for your own classroom expectations. Most of the teachers using Seesaw have not reported additional issues after having the increasingly important "digital citizenship" conversation with their students. It's all part of the learning process!
By default, all new student items and comments require teacher approval. This will prevent any inappropriate content from being shared with parents or posted on your blog. You can delete it from the approval queue and have a conversation with the student.
However, in Class Code Shared Sign in mode, we do show unapproved items in the student's own journal, but not in the Class Feed. This is so they can see feedback left on their work by the teacher, make a copy of it to make edits and resubmit, etc.
Additionally, with our Link item type, we have a list of blocked URLs to protect against explicit content being shared from online sources.
