Classification of Exhibit Evaluation: How deep should Occam’s razor cut?

In this article, Jacksonville State University's Stephen Bitgood responds to Roger Miles, a proponent of the Occam's Razor principle in determining the number of exhibit evaluation types, which argues for parsimony (fewest possible). Bitgood offers a rationale for Screven's four-type evaluation model based on multiple dimensions (when, why, how, what and who), accepts Miles's three-stage model of evaluation, and addresses Miles's criticisms of the use of remedial evaluation as one of the evaluation types. which Bitgood argues should not be cut from the list of evaluation types.
