Issues in the pragmatics of qualitative modeling: lessons learned from a xerographics project
The photocopier is one of the most complex machines because xerography involves many types of physical phenomena. ARIA is a qualitative simulation of xerography that is intended to teach technicians the reasons behind some of the subtle problems that occur in copiers. This effort to model xerography exposed shortcomings in the techniques of qualitative modeling as applied to complex systems and helped to better understand the impact of certain basic modeling decisions.
The evaluation of text editors: methodology and empirical results.
This paper presents a methodology for evaluating text editors on several dimensions: the time it takes experts to perform basic editing tasks, the time experts spend making and correcting errors, the rate at which novices learn to perform basic editing tasks, and the functionality of editors over more complex tasks. Time, errors, and learning are measured experimentally; functionality is measured analytically; time is also calculated analytically. The methodology has thus far been used to evaluate nine diverse text editors, producing an initial database of performance results. The database is used to tell us not only about the editors but also about the users—the magnitude of individual differences and the factors affecting novice learning.
