Toward a Model of Knowledge Structure and a Comparative Analysis of Knowledge Structure Measurement Techniques.
Koubek, Richard J.; Mountjoy, Daniel N.
A proposed model of human knowledge structure was studied, beginning with an operational definition of knowledge structure. A battery of available knowledge structure measurement techniques was used to detect structure differences between two experience level groups in the domain of clerical work. Subjects were 15 experienced secretaries and 15 secretaries with no more than 1 year of secretarial experience. Techniques used included card sorting, hierarchical clustering analysis, repertory grid, multidimensional scaling, Pathfinder, and pairwise similarity ratings. Subjects performed the standard tasks associated with each measurement technique. Results validate the existence of all model dimensions. Two dimensions were affected by experience level, and post hoc analysis revealed that an additional dimension, structure complexity, is a function of experience level differences, and should be included in future model development. The capabilities of the measurement techniques differed. Hierarchical clustering analysis was the most effective technique for detecting structure differences between the subject groups. In refining the proposed model, new knowledge structure measurement methodologies should be developed to provide a more comprehensive examination of the important parameters. An 83-item list of references is included. Six figures and three tables present study data. (Author/SLD)
