Given the enormous popularity of YouTube, it’s not surprising that an education-specific version of this video-sharing web site should emerge–and on March 6, that’s just what happened. TeacherTube, the brainchild of 14-year education veteran Jason Smith, gives teachers a more educationally focused, safe venue to watch and upload videos that help demonstrate a new concept or skill, address specific learning objectives, or provide professional development for their fellow educators. TeacherTube includes daily featured videos on topics such as teaching about the digestive system, or how to make classroom posters with Microsoft Excel–and it also offers a video tutorial on how to upload your own videos to the site. Users are able to rate videos and leave comments; search for videos by tags; find, join, and create video groups to connect with people who have similar interests; and even customize their experience by subscribing to member videos, saving favorites, and creating playlists. When you upload videos to the site, you can choose to broadcast them publicly or share them privately with only those you invite. The site’s services are offered free of charge to all users.
