From: THOMPSON%umass-cs.csnet@CSNET-RELAY.ARPA I am looking for information about the knowledge structure differences of people who have different levels of expertise in a subject. For example, what is the difference in the knowledge structure of an "apprentice", a "journeyman",or a "master". I will be happy to collect these references and repost them. Please send them directly to me (via csnet). Roger Thompson Thompson@UMASS

From: bulko@SALLY.UTEXAS.EDU (Bill Bulko) My attempted mail reply to thompson@umass-cs.csnet failed, so I'm posting this instead. The request was for pointers to articles dealing with how varying levels of expertise could be represented. My research is related to problem solving in physics, and so I have read several papers dealing with the way people learn how to solve problems in technical fields. Below is an excerpt from my proposal containing the related (annotated) references; I hope that they prove helpful. Bhaskar, R., and H. A. Simon, "Problem Solving in Semantically Rich Domains: An Example from Engineering Thermodynamics." Cognitive Science, Vol. 1, No. 2, April 1977. This is a study of the processes used by people to solve problems in semantically rich domains, and how these processes compare with those in general problem-solving domains. The authors choose the field of thermodynamics, and use a protocol-encoding program called SAPA, which they theorize corresponds to their subject's problem-solving behavior. Chi, M. T. H., P. Feltovich, and R. Glaser, "Categorization and Representation of Physics Problems by Experts and Novices." Cognitive Science, Vol. 5, No. 2, April-June 1981. The authors compare the ways experts and novices categorize physics problems and form physical models of the problems based on the categories created. Studies are presented which investigate the implications of the differences found for problem solving in general. Larkin, J., J. McDermott, D. Simon, and H. A. Simon, "Models of Competence in Solving Physics Problems." Cognitive Science, Vol. 4, No. 4, October- December 1980. This article discusses how a person's experience and expertise in solving physics problems determine the process by which he solves them. The authors describe a set of two computer programs which they claim are accurate models of "expert" and "novice" problem-solving protocols. Larkin, J., and H. A. Simon, "Learning Through Growth of Skill in Mental Modeling." Proceedings of the Third Annual Conference of the Cognitive Science Society, p. 106. The authors study how people develop the ability to take physical situations and re-represent them in terms of scientific entities. They present a program called ABLE, which models the performance of human experts and novices as they solve physics problems, from this learning point of view. Luger, G., "Mathematical Model Building in the Solution of Mechanics Problems: Human Protocols and the MECHO Trace." Cognitive Science, Vol. 5, No. 1, January-March 1981. Luger describes an automatic problem solver, MECHO, and describes how it can be used for model building and manipulation in solving problems in physics. He compares traces of MECHO with the problem-solving protocols of several human subjects, and hypothesizes that these traces are similar to the model-building techniques that people in general use.

A related paper is : Mark Weiser and Joan Shertz. "Programming problem representation in novice and expert programmers." International Journal of Man-Machine Studies. December 1983. pp. 391-398. This paper is an application of some of the Chi, Feltovich, and Glaser methodology to the problem space of programming, with generically similar results. Differences in detail include categories of problem-solving used and not used by experts (algorithms yes, data-structures no), and differences between expert programmers and expert former programmers now programming managers. -mark Spoken: Mark Weiser ARPA: mark@maryland Phone: +1-301-454-7817 CSNet: mark@umcp-cs UUCP: {seismo,allegra}!umcp-cs!mark USPS: Computer Science Dept., University of Maryland, College Park, MD 20742
