Please let’s personalize feedback to students.  If you can choose the first assignment to start, provide video feedback to each student and use their name a few times.

Brighspace/D2L/MindsOnLine – has a built in Annotator that is really excellent – lets me do my feedback online within the platform without having to go to outside PDF Annotator if I like.

I still like to include Video feedback too and LOOM is now my goto as it is very quick, and gives me a responsive embed code that works great on any platform.  Also lets me know when my videos are watched!
