ClipChoose is a free polling tool that I featured in a blog post last month. On ClipChoose you can create a poll that is based on a comparison of two or more videos. In the video embedded below I demonstrate how to create a video-based poll on ClipChoose.
Applications for Education
ClipChoose could be a good tool to use to create video quizzes for a lesson about bias and propaganda. When teaching students about types of propaganda I could put two or three videos in Clip Choose and ask students to select the one that demonstrates the use of a particular propaganda technique. For example, if I wanted my students to practice recognizing the use of "glittering generalities" I would put in a video that demonstrates that method and two videos that don't.
