A dedicated student support website is available at Please refer students there for complete information.

These support services are available:

  • The Hixon Writing Center will be conducting its one-to-one meetings with students online; you can find more information at
  • Deans tutors will continue to be available to support Caltech undergraduates. Students are encouraged to utilize whatever video chat apps they prefer in order to communicate most effectively with tutors, and tutors should continue tracking hours as usual. Information can be found at

Zoom bombing is a phenomenon where uninvited people disrupt a zoom meeting. Keep Zoom invitations shared only with students (never publicly) and have screen sharing off for participants (now the default setting). More info here.

Both of these applications allow secure, FERPA-compliant exchange of assignments, feedback, and grades with students; they just have different features. Canvas allows streamlined hand-in, use of grading rubrics, feedback via typed or annotated comments, and voice/video feedback, and recording/return of scores. Gradescope has expanded functionality for problem sets and coding assignments, including batch grading of individual problems across an entire set of submissions and use of grading rubrics. We suggest exploring the documentation for Canvas Assignments, Canvas SpeedGrader, andGradescope a little to find out what might be best suited to your course. We also discuss different types of assignments here.

Uploading videos directly into Canvas allows sharing only with enrolled students and approved auditors; that is the recommended method at this time (note that this has changed: in Caltech's former LMS, Moodle, we were not able to host video materials directly).

Alternatively, Google Drive can be used to store class videos so that they are available for streaming to students, yet privacy and security can be controlled. Find out more here. Links to videos in Google Drive can be added to Canvas.

If you are using publicly available videos that have no student information in them (e.g., on YouTube or Vimeo), you may link to them from your Canvas course.

It is possible to use other applications; please exercise caution and consider carefully what kind of information is being shared via third-party applications. Find out more here.

We have set up a YouTube channel with Caltech-made demonstrations and how-to's. The pages under Tech & Tools also contain links to support materials that also contain video tutorials.

Sure, we would recommend going through the pages in the Advice & Guidance section of the website, as these resources walk through key considerations and offer models for remote/online courses that have worked well at Caltech.

Under certain limited circumstances, auditing of courses by individuals with legitimate educational interests may be allowed. Faculty and instructors are under no obligation to permit auditors. Division chairs must review lists of potential auditors before they can join courses; once approved, a procedure will be provided to faculty/instructors. For more information, please contact your division office.
