In the Online classroom, there is a Screenshare option which both you and your students can use to share documents on their screen! This works best when using Google Chrome, and you will need to download a browser extension prior to having the lesson to ensure that your computer has access to your computer screen and can display this in the classroom. You will see a pop-up prompt you to do this when you try to screen share for the first time.
Your screen will be visible to all participants if you choose to share it in the Online Classroom. You can share either your whole screen, or just a specific window (e.g. you could share a PDF you have open, without sharing the web browser open in the background)
Once you activate screen-share, you will get a pop-up screen, which will give you options to share either a specific application or your entire screen. Choose exactly what you’d like to show, and hit ‘Share’.
