Ustream.tv can be used within an educationlearing situation to be able to view videos on a variety of different topics. These topics include but are not limited to presentations, lectures, informational videos on different countries and cultures. For example, major political events such as debates, speeches, rallies, talk shows, and school and business events and training are all available on Ustream.tv. The use of ustream.tv would open up a completely new group of potential learners and teachers with which to communicate. This application could also be used by students required to miss a great deal of class to view the classes they are missing and for them to be able to keep up with the rest of the class' lessons. Another way that ustream.tv can be used within an educationlearnig situation is by allowing classrooms of students to communicate back and forth via videos or allow students to view a performance that is going on somewhere else around the world, an opportunity they would not have had otherwise. Ustream.tv can be very beneficial for educators. It is appropriate for all ages from Kindergarten through high school and college, though teachers should preview the videos before showing their students. Another benefit of Ustream.tv is that it is free. It also uses "popular video formats, such as FLV, WMV, MP4 and MOV."
