Computers in Education
University-level introductory programming courses, CS0 (non-majors) and CS1 (majors), often teach an industry language, such as Java, C++, and Python. However, such languages were designed for professionals, not learners. Some CS0 courses teach a graphical programming language, such as Scratch, Snap, and Alice. However, many instructors want a more serious feel for college students that leads more directly into an industry language. In late 2017, we designed Coral, an ultra-simple language for learning to program that has both textual code and a graphical flowchart view. Concurrently, Coral's educational simulator was designed hand-in-hand with the language. Coral was designed specifically for learning core programming concepts: input/output, variables, assignments, expressions, branches, loops, functions, and arrays. Coral is intended as a step in learning; once Coral is learned, students might transition to an industry language. This paper describes Coral, including the design philosophy and pedagogical considerations. This paper also includes data on student usage and perspectives of Coral during the Summer and Fall 2018.
