For Active Learning, the ideal is that

"Class time is spent on collaborative activities in
small, assigned teams".

   For Spring 2021, our classes are going to be entirely
remote.  So our "collaborative activities" will consist
mostly of working together on our Mastering Physics HW
problems, with lots of Learning Catalytics questions
(many more than we would usually have in an in-person
class).

   The "small, assigned teams," which we would have been
using had we been meeting in person, will be replaced by
dividing our class up into two sections of about 20
students each.  Each of the two sections will be
assigned a dedicated Learning Assistant (LA) to whom
you may address questions by chat during the remote
class meetings and recitations.  If the LA cannot 
answer your question directly, then they will ask
me to address the question verbally during the
remote class meeting.

   It looks like our class is going to have about 40-50
students; so, I expect that, in addition to being able
to direct questions via chat to your LA, you will be
allowed to unmute your microphone and ask questions
at any time during class (as long as this does not get
unmanageable).

  In in-person Active Learning, "You will, at times, be 
required to report your team's findings to the entire
class." In an in-person class, your team, when called 
on, must show their whiteboard work for a particular
problem, and explain the work to the entire class.
We won't try to have a remote version of this aspect
of Active Learning in Spring 2021.

  Thanks, GBA.
