Kessler, Claudius M. and Anderson, John R. (1986): A Model of Novice Debugging in LISP. In: Soloway, Elliot and Iyengar, Sitharama (eds.) Empirical Studies of Programmers June 5-6 1986, 1986, Washington, DC. pp. 198-212.

“This paper reports an investigation of novice programmers trying to debug one-line LISP functions. We present a model of debugging based on protocol data and introduce a production system simulation of the ideal novice debugger. We conclude with a discussion of the applicability of such a model to the teaching of programming in LISP.”

Kessler, Claudius M. and Anderson, John R. (1986): Learning Flow of Control: Recursive and Iterative Procedures. In Human-Computer Interaction, 2 (2) pp. 135-166

“Two experiments were performed to study students' ability to write recursive and iterative programs and transfer between these two skills. Subjects wrote functions to accumulate instances into a list. Problems varied in terms of whether they were recursive or iterative, whether they operated on lists or numbers, whether they accumulated results in forward or backward manner, whether they accumulated on success or failure, and whether they simply skipped or ejected on failure to accumulate. Subjects had real difficulty only with the dimensions concerned with flow of control, namely, recursive versus iterative, and skip versus eject. We found positive transfer from writing iterative functions to writing recursive functions, but not vice versa. A subsequent protocol study revealed subjects had such a poor mental model of recursion that they developed poor learning strategies which hindered their understanding of iteration. It is argued that having an adequate model of the functionality of programming is prerequisite to learning to program, and that it is sensible pedagogical practice to base understanding of recursive flow of control on understanding iterative flow of control.”

“ Computer programs emerge as the outcome of complex human processes of cognition, communication and negotiation, which serve to establish the meaningful embedding of the computer system in its intended use context. ”
