I really enjoyed the ease of use with this material. I enjoyed the fact that the information could be presented in English and Spanish. I also liked that the video not only provided audio, but subtitles. This would allow students will visual and auditory disabilities to follow along with the video. I also liked how there were different versions of the topic quiz. This could prevent cheating amongst students, but also provide a student with another opportunity to test their knowledge of the topic if they weren't success the first time. I think that is great that students are able to use this material at their own pace. i could see myself using this as supplemental material for my lessons if a student was struggling or wanting extra practice with a specific concept.
