A process model to explain bugs produced by novices early in a programming course are presented. (The term "bug" refers to an error in a person's behavior, particularly an error in a computer program they have written.) The model is motivated by interviews of novice programmers solving simple programming problems. The key idea is that…

This report examines the features and performance of the BUG-FINDing component of MENO-II, a computer-based tutor for beginning PASCAL programming students. A discussion of the use of artificial intelligence techniques is followed by a summary of the system status and objectives. The two main components of MENO-II are described, beginning with the…

This report describes PROUST, a computer-based system for online analyses and understanding of PASCAL programs written by novice programmers, which takes as input a program and a non-algorithmic description of the program requirements and finds the most likely mapping between the requirements and the code. Both the theory and processing techniques…
