  • What if learning to code weren't actually the most important thing? It turns out that rather than increasing the number of kids who can crank out thousands of lines of JavaScript, we first need to boost the number who understand what code can do. As the cities that have hosted Code for America teams will tell you, the greatest contribution the young programmers bring isn't the software they write. It's the way they think. It's a principle called "computational thinking," and knowing all of the Java syntax in the world won't help if you can't think of good ways to apply it.
  • Researchers have been experimenting with new ways of teaching computer science, with intriguing results. For one thing, they've seen that leading with computational thinking instead of code itself, and helping students imagine how being computer savvy could help them in any career, boosts the number of girls and kids of color taking—and sticking with—computer science. Upending our notions of what it means to interface with computers could help democratize the biggest engine of wealth since the Industrial Revolution.
  • Much like cooking, computational thinking begins with a feat of imagination, the ability to envision how digitized information—ticket sales, customer addresses, the temperature in your fridge, the sequence of events to start a car engine, anything that can be sorted, counted, or tracked—could be combined and changed into something new by applying various computational techniques. From there, it's all about "decomposing" big tasks into a logical series of smaller steps, just like a recipe.

  • Because as programmers will tell you, the building part is often not the hardest part: It's figuring out what to build. "Unless you can think about the ways computers can solve problems, you can't even know how to ask the questions that need to be answered," says Annette Vee, a University of Pittsburgh professor who studies the spread of computer science literacy.

    "Unfortunately, the way computer science is currently taught in high school tends to throw students into the programming deep end, reinforcing the notion that code is just for coders, not artists or doctors or librarians. But there is good news: Researchers have been experimenting with new ways of teaching computer science, with intriguing results. For one thing, they've seen that leading with computational thinking instead of code itself, and helping students imagine how being computer savvy could help them in any career, boosts the number of girls and kids of color taking-and sticking with-computer science. Upending our notions of what it means to interface with computers could help democratize the biggest engine of wealth since the Industrial Revolution."
