Using Zoom to Connect Remote and In-class Participants in General Purpose Classrooms


There may be occasions when instructors wish to connect a remote guest lecturer or student to the proceedings of a campus-based class.  A combination of Zoom and classroom technology can make simple sharing of content to two locations possible. The following steps will enable instructors to streamline the process.

  1. Log into the instructor PC (Main PC) in the classroom with your University directory credentials.
  2. Open your PowerPoint or Google Slides presentation, web page or other application on the instructor computer.
  3. Log into Zoom and join the class meeting on the instructor PC.
  4. Check your speaker and microphone settings to make sure the classroom audio is synced with the Zoom meeting room. Change the Suppress background noise setting under Audio Settings from Auto to Low to help eliminate static in the audio heard by online participants. This adjustment needs to be made only once on the classroom computer.
  5. Select Share Screen on the Zoom meeting task bar.
  6. If sharing PowerPoint or Google Slides, switch into presenter mode.
  7. On the Crestron panel click on PC Main as the source to route to the Projector destination.
    Screenshot the Crestron panel ,click on PC Main.

NOTE: With this set up students in the classroom will see content on your computer projected on a screen in the room; remote participants will see your computer content shared in the Zoom room.

Sharing the Doc Camera

If your intent is to share the content displayed by the document camera with remote and local participants, you must do so by projecting the Zoom shared screen content.  This enables you to maintain audio between local and remote participants.  To switch between sharing instructor PC content and document camera images, follow these steps:

  1. Stop screen sharing in Zoom if you have been sharing other content.
  2. Click on Share Screen in the Zoom meeting task bar.
  3. Click on the Advanced tab at the top of the window.
  4. Click on the Content from 2nd Camera option, then click on Share.
  5. On the Crestron panel, make sure you are still sharing PC Main to the Projector.
  6. Place your content under the Document Camera head. See Guide to Classroom Document Cameras for more operational details.

 (The Doc Camera button on the Crestron panel would be appropriate if viewers are only in the local classroom.  The sharing method described above will ensure that audio works for remote viewers.)

Using a personal computer

Some faculty prefer to present with their own computer, often a Macintosh. To share content with local and remote participants, follow these steps:

  1. Connect your personal computer to the Crestron using one of the HDMI cables on the lectern that is appropriate for your device.
  2. Open your PowerPoint or Google Slides presentation, web page or other application on your personal computer.
  3. Log into Zoom and join the class meeting on your computer.
  4. Check your speaker and microphone settings to make sure the classroom audio is synced with the Zoom meeting room. Change the Suppress background noise setting under Audio Settings from Auto to Low to help eliminate static in the audio heard by online participants. This adjustment needs to be made only once on your personal computer.
  5. Select Share Screen on the Zoom meeting task bar.
  6. If sharing PowerPoint or Google Slides, switch into presenter mode.
  7. On the Crestron panel, click on HDMI Device (or VGA Device) as the source to share to the Projector. This will display the Zoom shared screen to the classroom screen so local participants can see the content.
