We program little turtles to dance on the screen then we play with real robot cars. Learning how to program is an awesome time. I love my job.
Computer Science may be intimidating but like any other field of study, you don't have to learn it all at once. We're skipping so much in this class. Don't worry about it. You'll have enough tools to figure out if you want to invest the time to learn the deeper, more challenging (and more powerful) stuff.
In order to understand basic computer programming, you will need to understand some of the components in your computer. If you understand the basic shape of the environment, the behavior of programming languages will have better context. You won't need to understand exactly how a processor works, but you'll need to know roughly how it fits into the picture so you can solve some common problems.
