How I Use It
I taught our school's video production / TV news class. We used this site to create some short clips to teach vocabulary, intro clips to longer videos and to be a setting scene in a longer video. We had an education account and we were able to have groups of students log in - but the biggest issue was only being able to have one student able to edit on the computer at a time. Overall I like this tool - but you really need an assignment for the students...do not just let them "go on and play".
This tool is as powerful as you make it. Students can create animations about things you have learned in class, re-telling a story they have read or summarizing a chapter. The ways in which you can use this tool is really endless. Students learned the basics quickly and really took their time to make the animation perfect. There are certainly some issues with the product - like cost and a lack of backgrounds, figures and music...but overall this is a great tool.
