There are two types of TED-Ed lessons. The first, TED-Ed’s award-winning original lessons, represent collaborations between expert educators, screenwriters and animators. Each collaboration aims to capture and amplify a great lesson idea suggested by the TED community. The second type of TED-Ed lesson can be created by any website visitor, and involves adding questions, discussion topics and other supplementary materials to any educational video on YouTube. Both types of TED-Ed lessons are used regularly – in classrooms and homes – to introduce new topics to learners in an exciting, curiosity-inspiring way.
