Sections
Lectures are supplemented by 90-minute sections led by the teaching fellows. Attendance at sections (at least one section for each of Sections 0 through 8) is expected.
When sections are running (see the schedule below for a list of section times), use the button below to log in via HarvardKey and access the section room.
Please do not arrive in the Zoom meeting room more than 15 minutes before your section’s scheduled start time. Similarly, if you would arrive more than 15 minutes late for a section’s scheduled start time, please select a different section to attend, so as to minimize disruption to the ongoing class.

Norms
All sections are held online via Zoom. Per the syllabus, you are expected to attend sections live, one per lecture. A calendar of sections will appear below once times have been set. Check the bottom of the calendar below for an indication of what time zone the calendar is displaying.
Sections have no attendance limit. We grab via an API your name and email attached to your Zoom account when you sign into the meeting for attendance so be certain that you can be properly identified, if you want credit for attending the section! (You are free to switch to a pseudonym, if you wish, during the section meeting itself!) Watching a recording of a section does not substitute for the section attendance requirement in the course’s syllabus.
Section recordings will ordinarily be posted some time on Fridays.
The course treats Zoom just like a classroom. For any meeting that you attend, be sure to:
- Participate from a quiet space (and not from a bed, car, hammock, plane, or train), where can you listen and speak. If you participate from a more public space, just be sure you won’t be approached or disturbed by others while there.
- Be sure to participate with your camera turned on, using horizontal (not vertical) video, unless your circumstances don’t permit.
If unable to accommodate these norms for some meeting, please watch the recording (if any) thereof. And please forgive if the staff ask you to log out so that all attendees are those fully engaged!
