Richard Byrne writes: “This week is Computer Science Education Week. I’ve long thought that every student should have some experience with computer science. I was introduced to some computer science concepts when I was in elementary school in the 1980s through the use of Logo, and that experience is still beneficial to me today. If you would like to have your students get a little computer science experience this week, here are some good resources.” Tools include MIT App Inventor, Blackbird, and Scratch.
