Towards a theory of HtDP-based program-design learning

Abstract

Program-design is an essential skill students in introductory computing courses must learn, but which continues to be difficult for students. Many introductory curricula focuses on low-level constructs, even when students are expected to gain higher-level problemsolving and program-design skills. How to Design Programs (htdp) is a curriculum that teaches a multi-step approach to programdesign, promoting multiple, interrelated program-design skills. My research explores how novice programmers use htdp-based techniques to design programs, the design-related skills students learn and use, the factors that drive their design decisions, and how these weave into a conceptual framework of htdp-based program-design.
