Using course tools>>Collaboration tools
As an instructor, you can record and archive Virtual Classroom and Chat sessions. Students cannot record these sessions, although you can allow students to review any archives you record.
To record a collaboration session:
Enter the Virtual Classroom or Chat session you want to archive.
Click the Start recording button at the top-right of the window:

Enter a name for the archive, then click OK.
Use the recording controls to pause, stop, and insert bookmarks, as necessary.
CourseCompass begins recording the session. You can later review the collaboration session recording.
