Tool: TED Ed
TED is a global community that aims to spread ideas. In order to do that it offers a set of freely available videos featuring talks by knowledgeable, interesting and respected figures covering almost all topics. Its newest initiative is TED’s education, which is intended to raise the voices and ideas of teachers and students. All TED talks are available for free in the form of short and powerful videos (usually 18 minutes or less).
TED offers a highly responsive search facility to search its talks based on topics, languages and duration. It is convenient to use and allows the viewer to search and select the talk which best suits their needs or interests. In addition, its functionality “Surprise Me” allows the viewer to let TED select a talk of a previously specified kind.
As TED is an online application, it needs internet connection. However, it allows you to download a talk in MP4 format, which let you see the videos even offline. You do not need to login in order to use TED but if you do it you will have a more personalized experience.
