This is a nice resource for advanced ESL students. The exercise can be used as an in-class activity or a homework assignment depending on the needs of students.
Students are first asked to look-up and define key vocabulary related to the Ted Talk. From there they are asked to answer several short-answer comprehension questions as the listen to and/or watch the talk. The talk is roughly 9:00 minutes long, but has the option of including subtitles should students need additional clues.
