TeacherTube (to quote from the site) "is an online media property for people to watch and share Education videos worldwide through a Web experience for everyone." This site as it continues to grow holds a lot of potential for teachers to share their experiences, cool lessons, thoughts and insights with one another.
I know that I find in my job as tech director that I often feel as if I’m recreating the wheel. It is only a couple of times a year that I actually meet with other techies face-to-face and get to share ideas with them and learn from what they are doing in their schools. TeacherTube could really help to create more cross pollination of ideas. In the short time I have been visiting the site I have found some great tutorials on how to use PowerPoint and CamStudio among other things. There are “channels” for the common secondary education subject areas as well as a spot to post student videos.
It seems that a TeacherTube could be used not only for sharing information among teachers, but for posting conference proceedings from across the country. Additionally teachers could post assignments (and potentially lectures) for students that could benefit the education community as a whole not just their individual classes.
