@ucbalumnus - This year, it is entirely possible that all of the practica and student teaching activities would indeed be virtual. I’ve seen plenty of discussion of “How do I supervise my student teacher in online classes?” and “How should I handle being a student teacher online this semester?” lately in an education forum that I participate in. In normal years, required classroom observation, practica, and student teaching activities for online students can be arranged in locations that are convenient to where the student is. I did my required classroom observations and teaching internship in two different states in two different parts of the US while completing my MS Ed. online at a university based in a third state. Students in that program were scattered all around the globe and everyone was able to find sites and supervision for required practica that were acceptable to our department.
