Wow! This slideshow is very visually appealing and extremely easy to use. I like that there is consistency with the description being presented down the left-side of the page and that I can go forward or backward through the slides. It was a nice touch that you included your own website as an example on one of the slides also. I think that students could easily use this lesson to learn more about design elements. I like that the quiz informed you if you were correct or incorrect. Do the students have to get 100% to "pass" the quiz? I missed a couple of questions and had a 40/50 (80%) and it said that I failed so I was just curious. I really don't have any suggestions for improvement except that there were two similar questions on your quiz (in a row) regarding contrast. The actual lesson was informational and easy to use. Great tool!
All of the links work and I really like the links to the quiz and video at the end.
