Read about the principals behind the design of Scratch in Communications of the ACM: Scratch: Programming for All: “Digital fluency” should mean designing, creating, and remixing, not just browsing, chatting, and interacting.:

It has become commonplace to refer to young people as “digital natives” due to their apparent fluency with digital technologies. Indeed, many young people are very comfortable sending text messages, playing online games, and browsing the Web. But does that really make them fluent with new technologies? Though they interact with digital media all the time, few are able to create their own games, animations, or simulations. It’s as if they can “read” but not “write.”

As we see it, digital fluency requires not just the ability to chat, browse, and interact but also the ability to design, create, and invent with new media, as BalaBethany did in her projects. To do so, you need to learn some type of programming. The ability to program provides important benefits. For example, it greatly expands the range of what you can create (and how you can express yourself) with the computer. It also expands the range of what you can learn. In particular, programming supports “computational thinking,” helping you learn important problem-solving and design strategies (such as modularization and iterative design) that carry over to nonprogramming domains. And since programming involves the creation of external representations of your problem-solving processes, programming provides you with opportunities to reflect on your own thinking, even to think about thinking itself.
