My Take
I find that my honors class students are more receptive to TED talks. They maintain focus on the speakers and reflect on the videos at a deeper level than the regular classes. I feel the talks are not applicable to lower level students and would be lost on them without a lot of teacher explanation.
How I Use It
This is a great way to have students look at a covered topic in a new way. It shows them what is new in the field of study. It is a great discussion or debate opener. Students can also be required to write a reflection on the video clip.
