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.
