My children's teachers were using FlipGrid for fun activities in their classroom so I decided to modify and use it in my classroom! We are now performing our skill checks on FlipGrid and the students are loving it! They also have to review two or three of their classmates each week and their responses are videos as well with corrective techniques. When we return to on campus classes, we will continue to use this as an additional psychomotor assessment!
This is a really easy program to create videos/screencasts. You get a link that you can post in course emails/announcements/assignments/syllabi, etc. It doesn't caption yet but I have put in the request for this feature. I use the free version.
This is a great resource for chemistry teachers. In particular, I recommend the math skills area and the "Introduction to Stoichiometry" (Level 3, especially!).
