'There is an activity I run with my students in the first class of semester. I tell them I’m going to play a video and want them to give me their impressions. How does it make you feel? Do you like it? Do you hate it? Are you without emotion? Then, I explain, I will reveal something about the video’s making and ask how this new information changes their impressions. Then, I divulge more of the video’s context, and ask once more for their responses.'
