You want to use a video... What if your school does not allow the use of YouTube?
Here are some alternatives:
- John Locker, subtitled the "Online Learning Network," has videos on a variety of subjects. They can be embedded into a web page. Use the search facility and categories. http://johnlocker.com/
- TeacherTube, the alternative to YouTube, has videos addressing various topics. http://www.teachertube.com/
- SchoolsTube, like TeacherTube, is intended to be an educational substitute for YouTube. It's relatively new, so there's not much there yet, but it is very promising indeed, and includes audio too. http://www.schoolstube.com/
- SchoolTube, which has lots of videos and pictures for use in the curriculum, as well as lesson plans and other resources. http://www.schooltube.com/
