Practice What You Preach: Full Separation of Concerns in CS1/CS2

摘要

We argue that the failure to separate the concerns in CS1 is the leading cause of difficulty in teaching OOP in the first year. We show how the concerns can be detangled and present a detailed reorganization of contents for CS1/CS2 with CS1 exposing only the client view. We also report on our experience with this new pedagogy after three years of implementation at our institution.
