Restrict Students from Commenting on Stream

Restrict students' ability to comment on the Stream by changing a Stream setting (this has to be done for each class). 
   
 
 Go to  Google   Classroom 
 Select a class 
 Click the settings gear in the top right corner 
 Scroll down to Stream (under the General section) 
 Change the setting next to Stream. Choose either "Students can only comment " or "Only teachers can post or  comment ). Do  not  leave it as "Students can post and  comment  - this is how they're accessing YouTube" * *See note below 
 Click Save in the top right corner 
 Repeat this for each  Google   Classroom 
 
 **This setting affects the announcements area of your  Google   Classroom  page. If you post announcements and want students to  comment  on them, choose the middle option. If you don't use this feature, limit it to only teachers who can post or  comment .
