Welcome to teaching impacts of technology, data collection, use and privacy. My name is Beth Simon and I'm a Computer Scientist, an Educator and a Professor in Education Studies Department here at UC San Diego. Before I tell you any more about me or this class, let me introduce you to a colleague. This is Art Lopez and I got to know Art maybe around 10 years ago because one of his students came up to him at his school where he teaches now and said, "Mr. Lopez, how come we don't have any computer science classes like kids in other school districts do?" And he thought, "That's a really good question. I need to look into that. " And what that led to it was a great collaboration where Arts started working with us in our efforts to bring professional development to help teachers who've been trained in other subjects, learn to teach computer science in the ways that we think all kids need to know computer. And Arts' been pretty successful. Here in his district, Sweetwater Union High School District, which is just South of San Diego and just North of the border with Mexico, 10 years later, they now have computer science courses in every high school in the district. And that is making an immense change in the lives of the students there, in terms of their careers and how we understand that computer science and computing really impacts our lives every day. And that got me really involved in this movement which is popular in the United States right now called CS for All, which is the picture of my laptop which it's pride of place I only have one sticker there. I do believe like many people around the nation and around the world that computer science and computational thinking are things that every student, every kid, every citizen needs to know, in the same way that we believe they all need to know reading, writing, and arithmetic. But it's a real challenge to get enough teachers prepared and capable of teaching the kids the computing that we need, and that is part of the goal of this class. In this course, we'll be particularly looking at the impacts of computing on our culture, our social interactions, and safety, law and ethics. You might be familiar with this purple diagram, it comes from a set of standards that were recently produced by an international association called CSTEACHERS.ORG. Now we know that whatever country or state you're in might have different standards but a lot of them are related to these. So, we'll use those as a grounding. But how are we going to look at impacts of computing? We're going to be taking a very problem-based approach. I mean we're talking about impacts of computing on our lives, so let's use our lives as a place to start. Depending on where you live, you may experience online shopping every day in your life. So, one of the things that we'll look at first is, how in the world does Amazon know what they should recommend that I might want to buy? We'll be digging into that and many other things but in this particular case, we want to look at how we can be able to figure that out. That will lead us to the new area of machine learning, and you will actually get the opportunity to train a classifying machine learning algorithm yourself, so that it can recognize three different poses of you. Now don't worry, it's not hard. I promise you it can't be bad, it involves kittens. As you will now see, we don't just cover the impacts of computing on culture, society, et cetera in this class, but the fact that we're looking at those impacts and the things that we use technology for everyday, we will then take those technologies and use that as an excuse to dig down into more fundamental computer science concepts. That's going to include things about networks in the internet, it's going to include things about data and analysis, and even some about sometimes about algorithms, and programming, and computing systems. Then, we'll go into and learn about a little bit about pedagogy. I knew that as practicing teachers or those of you who are practicing teachers you may know a lot about this, but I will use this as an excuse to share with you some of the most recent research that might be applicable in your classroom. In this course, we're particularly going to be looking at retrieval practice. This has been studied for a while but recently a lot of new research has come out about how amazingly effective it is to have students practice for treating their knowledge through a test type scenario versus restudying. We'll also, of course, be giving you time to look at and explore lesson plans and resources that you can use to help teach your students the scene concepts that you learned about in this course. This one particularly will be having you look at TED talks as a source for getting students to look at the potential future impacts of technology on our society, and we'll get to actually read the first chapter in a book called The Secret Code Menace. This is a book for young adults that actually helps teach them some basic computer science concepts while they're getting to read a fun book. So, if you're interested in learning and learning how to teach about how our data is collected, used, and what privacy implications we have, then I hope you'll join us in this course and in this specialization.
