The morning general session on Saturday had four panelists giving the past, present, and future of technology along with audience participation, and audience Q and A- all in 45 minutes. Not much in depth was done. There was also a lot of pushing of TI and Pearson solutions, which given the background of two panelists, was not shocking.
One thing I did learn about was Flipgrid. It seems essentially to be a video version of threaded discussion. I think you have to be careful about how you use it because one advantage of writing is you can see the length of a post quickly and parse quickly to a part you wish to reread. This is harder on video. On the other hand for some students creating a video response might be easier. Flipgrid claims they can add close captioning to student videos to meet accessibility requirements.
