A good option is to pre-record any lecture material (not students/Zoom class meeting) and upload it to Canvas. You can easily use Zoom to create the recording.

How To:

Open your PowerPoint or other resource you will be using
Start Zoom
Test your microphone for sound quality; consider using a headset with an external microphone to capture better audio
Start the Recording, making sure you select to save to the Zoom cloud and proceed with your session
Click on the Share Screen button and select the resource you opened in Step 1, then click Share.
On your computer, you can click through your PowerPoint or other course lecture materials and talk.
In the top left corner of your screen, you can click to pause or to stop your recording.
Once you are done, click End Meeting to stop your recording and exit Zoom.
Go to app.vidgrid.com. Click Enterprise Log-in. Log-in with your Bucks email address and password. Locate your recording. Double click on your recording name, it should read Zoom meeting..., to edit it to a title more meaningful to your students.
Share your VidGrid recording to your students by embedding it to a Page, Assignment, Discussion or Announcement in your Canvas course space. Learn more about using VidGrid at https://bucks.libguides.com/vidgrid

Recommendations

Add closed captions
- In VidGrid, you can add machine generated closed captions to your recordings. The closed caption is about 85% accurate and you can edit the captions. Tutorial at https://bucks.libguides.com/vidgrid
Chunk your material.
- Keep videos around five minutes.
- Several short videos are better than one long one.
Check for student understanding
- Consider adding a survey or quiz to your video to assess student. You can use VidGrid to add in-video questions. Then, by creating an Assignment in Canvas and selecting External Tool > VidGrid Quiz, click save/publish, and following the prompt in your Assignment to select your video with in-video questions, you will sync the student's grade on the in-video quiz to the Canvas Gradebook.
