Computers, smartphones, smart systems, and other technologies are woven into nearly every aspect of our daily lives. As computational technology advances, it is imperative that we educate young people and working adults to thrive in a computational world. In this context, the essential question for American education is: In a computational world, what is important to know and know how to do? This paper argues that computational thinking is both central to computer science and widely applicable throughout education and the workforce. It is a skill-set for solving complex problems, a way to learn topics in any discipline, and a necessity for fully participating in a computational world. The paper concludes with recommendations for integrating computational thinking across K-12 curriculum. .
