 Hello, I'm Professor Stephen Neshevet, and this is the Assignment and Preview video. This is the video that's going to tell you what you need to do to get ready for, before coming to class. So here's what you need to do. What I would like you to do is watch videos one and two that have been prepared for you for this, and and of course the video that you're watching right now. On the second video, there are two parts if you recall, the first part was identifying a problem or question that would be suitable for a flipped classroom project. I would like you to come up with two candidates for that, and write down in your notebook what those two candidates are, and make sure that you write down whether, and to what extent those two candidates satisfy the five criteria for a good flipped classroom topic are, and what will happen is that you'll come into class, and at some point in the class we'll solve, we'll actually tackle part two, which is solving the problems of one of those two, and discussing and maybe comparing notes on that. So your your pre-lab is to take the second video, grapple with part one, two, two problems. Okay.
