15-110: Principles of Computing
An introductory computer science course for students with little to no computing experience. Students will learn the core elements of programming in Python and will also receive a broad overview of big ideas in the field of computer science. The course begins with fundamentals of programming (data, variables, functions, conditionals, loops, and recursion) and the basics of computer organization (data representation and memory), then introduces major data structures (lists, dictionaries, trees, and graphs), the core concepts of efficiency (through runtime analysis and a case study of search algorithms), and how computing is scaled for practical use (concurrency and the internet). The course concludes with an overview of how computer science can be used as a tool to support other domains (data analysis, simulation, and machine learning) and how computer science influences and is influenced by the world (history, ethics, and modern events).
