SchoolTube - A YouTube Alternative
SchoolTube is a free video sharing site for students and educators (K-12). It is a safe environment for students to post their work, and teachers can easily find videos to support their lessons. All the content on SchoolTube is moderated and approved by registered teachers. Students, 13 and over, are able to create their own accounts.
SchoolTube is a safe alternative to YouTube, which is often blocked at schools - particularly at the elementary level. To prevent cyber-bullying commenting is not permitted, however there people are able to rate videos. Another nice feature is that the videos come with embed code so that they can be used on a blog.
The video below gives a brief explanation of SchoolTube and the uses within a school setting.
