We have a few ways for professors to record classes and offer lectures online. VidGrid (mostly for recording your screen). With Zoom, you can record a live video meeting held with your students. Record your written notes and audio, at the same time, with Livescribe.
You can then share the products of any of these methods in your Canvas class or Google Drive.
Note: If you're a student looking to record your class, please talk with your professor and/or Student Accessibility Services.
