Perceptual Structure of Scientific Knowledge. Final Report.
Johnson, Paul E.
The research contained in this report is directed at the problem of assessing structures of knowledge in science. Toward this end graduate as well as undergraduate students were asked to make judgments of the perceived similarity of expressions that mark or label concepts in the subject matter of physics. An apriori model of the structure of subject matter knowledge was used to generate task materials as well as interpret the judgment data. Evidence presented in the report lends suppport to the notion that mastery of a domain of knowledge can be indexed by procedures which might also reveal the state of a student's knowledge early in this educational experience. The adequacy of this approach to educational assessment (essentially through the medium of construct validity) should be tested by further research. Especially important, is research which reveals the role knowledge structure such as those identified in this report can play in problem solving behavior. (Author)
