Chapter 3 considers the goal of using computing as a tool to support learning in other domains, including the goals of computational thinking. One of the student populations in this chapter is STEM students. eir goal is to be educated citizens and workers, who can use physics, mathematics, and STEM problem-solving skills in their lives. For these students, much of the research has emphasized programming as a medium. Programs are a notation that expresses causality and time better than traditional mathematics.
