SchoolTube

Schooltube is an online video sharing site that was created for student and teacher use.  Students and teachers can use SchoolTube to access a wide variety of educational videos.  All of the videos found on SchoolTube have been screened and approved by a moderator, so teachers can be sure that the videos they are sharing with their students are appropriate and "school friendly."  Videos are sorted by category, and users can search by topic, making it easy to locate relevant video content.  Users can also upload their own videos, sort them into categories, and tag them so that others will be able to find them (after they have been approved by a moderator). 
Schooltube also allows teachers and students to create their own channels.  Teachers can set up channels dedicated to their classes, where they can post student created videos, as well as the videos that they want their students to watch.  Students can also create channels to keep track of their favorite videos and the videos they have uploaded.  This site would be a great tool for classroom use.  Teachers could use their channels to post educational videos they want their students to use as resources for research projects, or to post videos for students to watch as as a basis for a written response.  They can also post student created videos made in the classroom.
