Good way to see what the common errors are so you can address. The bar at the top gets you to see whom is participating which is great. What do you do if for those students whom don’t participate? What incentive do you use to encourage this participation?
It is great to get immediate feedback that can be used to inform the next instruction. However, I am wondering if this result is saved so I can visit it later. It might not be easy to track all struggling students while teaching synchronously.
