My favoritist favorite favorite thing about Google Classroom is the Private Comments. Comments in Classroom are not feedback, they are conversations. BEFORE a student even starts an assignment they have the opportunity to ask for help or clarifying question in the Private Comments. You can reply. You can have back and forth conversation with students.
Assign Private Comments
I would much rather have conversations with students than grade students. Opening up stacks of digital paperwork is my least favorite thing to do. My favorite assignment is to ask a question and request that they put their response in the Private Comments. Then I am able to have a back and forth conversation with each student to ensure that EVERY SINGLE STUDENT takes a step in their learning.
