Share Screen

Last updated: June 27, 2023.

Overview: Class allows an instructor to showcase the content on their screen using the screen share feature.

Screen sharing creates a forced-follow experience for the learners and provides the instructor with complete control over the pace at which your learners are exposed to the material.

If you are unable to share on macOS, please follow the steps in this knowledge base article.


To share the content or screen, click Share Screen located in the center of the bottom toolbar. 



Share the entire desktop and specific application windows. Choose one of the screen share options (shown here as Desktop 1, 2, or Google Chrome). The instructor can display different monitors or a specific application. Once selected, click Share.



  • Music or Computer Sound Only: Only share the computer’s audio (the selected speaker in the instructor’s audio settings).
  • Portion of Screen: Share a portion of the screen represented by a green border. The border can be adjusted as needed during the share by clicking and dragging any side or corner.
  • Content from 2nd Camera: Share a secondary camera connected to the instructor’s computer; for example, a document camera or the integrated camera on the instructor’s laptop. – Available on macOS and Windows app only.


To allow other users to share their screen, select the caret “^” to the right of Share Screen to open the Advanced Screen Sharing menu. Instructors can toggle on who can share, who can start sharing, when someone else is sharing, and who can annotate.


When the instructor start sharing their screen, the meeting controls will move into a menu that the instructor can drag around their screen.

  • Mute/Unmute: Mute or unmute the microphone.
  • Start/Stop Video: Start or stop the in-meeting video.
  • New Share: Start a new screen share. The instructor will be prompted to select which screen they want to share again.
  • Pause Share: Pause the current shared screen.
  • Annotate: Display annotation tools for drawing, adding text, and so on.
  • More: Hover over More for additional options.
    • Record: Start recording locally or to the cloud.
    • Meeting Info: Shows the current meeting’s ID, host, passcode, invite link, participant ID, and encryption status.
  • Reactions: Add a reaction
  • Raise Hand: Raise or Lower Hand


The instructors on macOS and Windows have the ability to see their shared content within the Class app as they are sharing. The screen being shared will show a green box around the content being displayed to learners. To see learners while sharing, select Video Placement: Float. Changing the Video Placement to Float will bring the gallery view outside of the app in order to be seen during a screen share.

Share Screen: If the instructor has a slideshow that they want to share, they would choose to Share Screen so that they are able to maintain control of the navigation pace and display of the slides to learners. 

Share Files: If you upload the slides in Share Files, learners can navigate the slides on their own but won’t see the instructor’s navigation, even if they choose to present the uploaded file at the end of Class. 

Think of the difference like this: in Share Files, you’ve just given participants access to the files: to download, scroll through, view at their own pace, etc. But when you’re presenting a slideshow through Screen Sharing, the instructors is controlling how and when the slides advance.

Share Screen on iPad


iPad instructors may share their entire screen, but may not share in these ways that are available on desktop:

    1. Music or Computer Sound only

    2. Portion of Screen

    3. Content from 2nd Camera

    4. A particular application


Advanced sharing options are available in the more button in the bottom toolbar, rather than as an additional option in the share screen widget


iPad instructors do not have the option to toggle allowing instructors only or all learners to start sharing when someone else is sharing as this option is available for the desktop Mac and Windows apps only.
