This chapter explores why teacher educators should teach teachers how to integrate coding across content areas and how to do so by applying concepts of computational thinking such as using algorithms, flowcharts, and Boolean logic to all fields. Teaching teachers how to teach coding across the content areas offers opportunities to diversify people in a field where intimidation, discrimination, and lack of opportunities has effectively kept the field of programming largely white or Asian and male. In addition, as our lives become more and more infused with technology, Rushkoff warns that we either learn how to program or become programmed. This means that not everyone needs to become a computer programmer, but everyone needs to understand how programming computers works. In other words, coding across content areas would help prepare all students, not just those pursuing the field of computer science, for the 21st century.
