Engineers apply computer science knowledge to problem solving, and we think children can, too. For more than two decades, we’ve been partnering with PK-12 educators to bring authentic, hands-on engineering challenges into the classroom. Core to these efforts has been helping educators support students as they engage in engineering practices—the habits and behaviors engineers rely on when solving problems. One of the practices that we want educators and students to be aware of is that engineers use computer science knowledge when designing solutions.
