Flipped learning is a reversal of the traditional teaching strategy, which has changed the timing of teacher's lectures and homework. In this revolutionary situation, the appropriateness of the before-class videos and other materials and the arrangement of class in the classroom play an important role in the fulfillment of application of the materials. Classical TED speeches are the excellent options for English language learners' flipped learning. This paper tends to make a case study of the application of TED speeches into flipped learning, taking the speeches with the keyword "transportation" as an example.
