Simplex Analyses of the Test Data: What Can They Tell Us?
Frayer, Dorothy A.
A Paradigm for testing concept attainment, comprised of twelve tasks, was formulated. These tasks were hypothesized to form a cumulative hierarchy. Tests were constructed in mathematics and social studies using the paradigm. Data for these tests was analyzed by Kaiser's method for fitting a perfect simplex and Schonemann's method for fitting a quasisimplex. Results suggest that tasks requiring recognition of attribute examples or concept examples are of least complexity; tasks requiring recognition of relevant attributes or the concept definition are of intermediate complexity; and tasks requiring recognition of irrelevant attributes or principles are of greatest complexity. Sample items are included in the appendix. (Author)
