... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested.

Pathfinder network scaling has been used widely to assess knowledge acquisition and inform interface design. While a large body of research agrees on the validity of this technique to develop knowledge structures, the rating task becomes cumbersome when users are faced with a large number of concepts to relate. Thus, a new rating method was created to help users determine the relationships between concepts. This new interface allows subjects to judge proximity by arranging concepts in visual space on a target. Traditionally, subjects were presented the concepts in pairs and made ratings on Likert Scales. Students (N = 88) at the Air Force Academy used both methods to rate the similarity of basic flying concepts. Results showed that the new method was more sensitive to differences in knowledge structures between experienced and inexperienced pilots (p < .01). Experienced subjects also preferred the new target method compared to the traditional rating method. The relative efficiency of the two methods is discussed.

The cognitive organization of a set of abstract programming concepts was investigated in subjects who varied in degree of computer programming experience. Relatedness ratings on pairs of the concepts were collected from naive, novice, intermediate, and advanced programmers. Both individual and group network representations of memory structure were derived using the Pathfinder network scaling algorithm. Not only did the four group networks differ, but they varied systematically with experience, providing support for the psychological meaningfulness of the structures. Additionally, an analysis at the conceptual level revealed that the four groups differed in the way concepts were represented. Furthermore, this analysis was used to classify concepts in the naive, novice, and intermediate networks as well-defined or misdefined. The identification of semantic relations corresponding to some of the links in the networks provided further information concerning differences in programmer knowledge at different levels of experience. Applications of this work to programmer education and knowledge engineering are discussed.

Models of users' procedural knowledge were derived from the records of command usage obtained from nine experienced users of the Unix operating system. Pairwise transitions between user command entries were analyzed for the purpose of identifying salient command patterns associated with task-based user behaviors. Structural models of command usage patterns were obtained from Pathfinder network scaling of Unix command events. The network representation of command patterns was evaluated as a method for abstracting users' procedural knowledge. These network scaling solutions revealed patterns that were common both within and across users' command usage.

McDonald, James E., Dearholt, Donald W., Paap, Kenneth R. and Schvaneveldt, Roger W. (1986): A Formal Interface Design Methodology Based on User Knowledge. In: Mantei, Marilyn and Orbeton, Peter (eds.) Proceedings of the ACM CHI 86 Human Factors in Computing Systems Conference April 13-17, 1986, Boston, Massachusetts. pp. 285-290.
In this paper we propose a formal interface design methodology based on user knowledge. The general methodology consists of 1) obtaining distance estimates for pairs of system units (objects, actions, concepts), 2) transforming the distance estimates using scaling techniques (e.g., Pathfinder network analysis), and 3) organizing the system interface based on the scaling solution. Thus, the organization of the system is based on the cognitive models of users rather than the intuitions of designers. As an example, we discuss the application of our methodology to the design of a network-based indexing aid for the UNIX on-line documentation system (MAN).

This paper investigates the effects of computer programming skills on the writing of ordinary instructions. Three computer experience groups (Naive, Beginner, Expert) wrote telephone directory instructions to one of three targets (another person, George Washington, or an English-understanding computer). Each subject performed this task twice, such that data could be collected from Beginners before and after one semester of computer experience. No effects of this Session variable were found, however, leading to a discussion of the learning versus selection hypotheses. Other results indicate that overall type of instruction strategy used was only significant for the computer target. When writing for a computer, Experts were more likely to use a whole name search, Naive users to use a separate name search, and Beginners to use a letter search. These results are interpreted in terms of problem representation and in terms of expectations of a natural language computer system. In addition, it was found that Experts used more looping and programming action statements than Naive or Beginner users, even when writing to another person. The programmer's advantages are then discussed. Also, the computer target was always the least likely to receive information in terms of alphabetization instructions, directory descriptors and fillers suggesting further burdens and expectations that users may place on natural language systems.

This report reviews work on defining and measuring conceptual structures of expert and novice fighter pilots. Individuals with widely varying expertise were tested. Cognitive structures were derived using multidimensional scaling (MDS) and link-weighted networks (Pathfinder). Experience differences among pilots were reflected in the conceptual structures. Detailed analyses of individual differences point to factors that distinguish experts and novices. Analysis of individual concepts identified areas of agreement and disagreement in the knowledge structures of experts and novices. Applications in selection, training and knowledge engineering are discussed.
