Mobento. Mobento's take on searching for educational videos allows you to search by category, organization producing the video, speakers, and length of video. You can refine your search by combining selections from each of those menus.
Applications for Education
Mobento won't change the way that you use videos with your students, but it could be helpful in finding a good video to use in a flipped lesson. Once you find a video you might want to try a service like EduCanon to create a flipped lesson that requires students to answer questions while watching the video.
