Awesome!!! This is a great supplemental tool! Multiple means of respresentation including alternatives for visual information (video) as well as providing alternatives for auditory information. This tool also provides different ways of interacting with the material. I appreciate that the questions were built right into the middle of the material so that kids can "test"what they have learned so far. I think adding the "keep learning"...to the end was a great way to extend academic discovery. I also like the assement tool that checks answers.
Some of the sound effects did not work when clicking on the answers. Alos, on the page with two videos, there was not a way to click out of the video or collapse from the large screen. If you did not already know how to just hit "ESC", you might feel frustrated. Overall, technically this was a great StAIR.
Time spent reviewing site:
I spent about 35mins looking at the videos and the extension piece at the end.
