This paper describes a new interface for PolygonR&D designed to facilitate student’s navigation between different levels of programming. In a first year programming class (CS1), many novice programmers have difficulty switching between thinking about low-level instructions, subroutines, and programs. Experienced programmers are adept at chunking a group of instructions into a subroutine, breaking down a task into cases which can be coded with low-level instructions, and breaking down complex programs into subroutines. In an attempt to help novices gain experience in navigating between the different levels of programming, the programming environment of PolygonR&D (a micro-world based on polygons) was enhanced to allow for easy exploration of subroutine outcomes without further programming. In two iterations of CS1, the new interface showed promise as an introductory aid for novice programmers.
