This is an incredibly handy tool for transforming video content that just about any classroom can make use of. Both teachers and students can customize online videos to prompt viewers to think critically, reflect, and respond. How much those viewers learn will depend, of course, on the original video and the quizzes or comments that you add, but there's enormous potential here for fostering a more learner-centric classroom experience. Creating informative, engaging videos can encourage students to be active viewers who critique what they watch. It's straightforward for teachers to upload their own videos, and there are tons of high-quality videos available (both from channels like Khan Academy and from other teachers) to use as stellar starting points. 

While passively watching online videos may require only lower-level thinking skills, the ability to isolate and encourage interaction with the most important aspects of a video increases the relevance of content and depth of learning, especially if teachers take advantage of the options to add supplemental resources and links. Furthermore, critical thinking skills such as analysis and information seeking can lead students to a transformation of knowledge if teachers let students research, create, and share their own video lessons. 

The main drawback is the volume of available content and the way it's organized. The search experience can be daunting. Many teachers have created and shared their own versions of the same videos, and it can be tough to wade through them all to find what you need. The tool could also use more features for annotating and remixing videos, especially the ability to combine multiple videos. Since this feature isn't yet available, the developers suggest a workaround: sequencing video lessons to create a similar student learning experience.
