They fit right in with the philosophy of the Four Pillars.
I've been using video assessments for years - in American Sign Language courses. It is an excellent way to see how they're doing and give feedback on specific aspects of their work. It's fun to think of how this can be done across other courses as well. I'll add it to my linguistics course in the spring - I think.
In my constant tinkering, I have gone almost exclusively with video assessments in my classes this semester. Is it better than my old traditional approaches? Yes. Do I need to tone it down and mix with other forms of assessments? Yes.
In case it's helpful (and you aren't using Flipgrid), here's a little video production guide I provide for my students. It's got a CC license, so use/share freely: https://drive.google.com/file/d/1c9cebOLfStPpYgUs1JYAOE_rH4K7_gz5/view?usp=share_link
