 My name is Colleen Lewis. I'm a computer science professor at Harvey Mudd College and the instructor for the class Programming and Scratch on edX. I'm really excited. You're interested in the course and I hope you take it But first you're probably asking what's this class even about? So we're gonna be doing computer programming, which is just writing rules for the computer to follow learning a language that the computer understands So what I tried to do is take a bunch of really interesting and important computer science topics and pack them into the course It's fun and accessible. So this will be a great course for kids But it'll be great course for anyone who's interested in learning a little bit more about computer science Lastly, I want to encourage you to take the course with a friend It can be one way more fun and two in computer science a lot of what we do is Collaborate to make really big cool things with computer science. You always need a big Collaborative team so start practicing that and join this course with a friend
