As part of the distance learning program, a couple of our courses are taped by this camera. It always reminds me that there will be other students from somewhere around the world experiencing what we have had in the class: the conversation between students and instructors will be heard once again through the video; once in a while, there might be a student passing across the screen because he or she was a little bit late to the class; and when we had the class of making Peanut Butter and Jelly Sandwich, all the laughters will be shared through the video.
