We propose to develop Computer Science 0 (CS0): a new introductory general service course, available to students across the university, to share the beauty, joy and awe of computing. This course has the potential to serve as a model for a new CollegeBoard Advanced Placement course in the works, which could have national impact. Students will be gently introduced to programming and computational thinking using a new graphical programming language called Scratch, with the emphasis on problems relevant to themselves and society.
