TED recently introduced a TED-Ed. The video library holds original videos created by educators around the world. The videos are screened by TED for quality and length (no video is longer than 10 minutes). They post a new TED-Ed lesson every week and highlight educational TED Talks on the weekends.
Visit TED-Ed to view the available videos, and to subscribe to the channel.
Help TED-Ed create more education videos – they want animators and content-creators (wouldn’t it be fun to see some homeschool high schoolers on there?)
