I gave you an Okay not because of the content, but because of the way the Powerpoint ran. I liked your concept, but it took me a minute to figure out the definition and what I was supposed to do with that...maybe some more directions? Also it would have been nice to have some way of marking off the words. I liked your quizzes, but you need a "back" button. I think with a bit of "tweeking" this would be an outstanding presentation.
I tried to view the video but it wouldn't work for me. Also the presentation froze on me on the first quiz. You needed some "back" buttons as I got stuck a few times.
