TED Talks are valuable sources that can be used in academic work. The speakers have been vetted for credibility. Always take notes when viewing these sources as you want to be able to identify any facts, statistics, or opinions of authority for possible use in research papers. If the link doesn’t work, just do an Internet search for the title of the assignment + TED Talk and you’ll get a working link. Then if you remember, notify the instructor of the problem.
