Exploratory Test of an Automated Knowledge Elicitation and Organization Tool

Abstract : his paper combines the contents of two papers that were presented at the ITS 98 conference one focusing on knowledge representation (Shute, 1998) and the other describing a knowledge elicitation tool (Shute, Torreano, & Willis, 1998). There are three main purposes of this paper. First, as a means to stress instructional and assessment implications of different knowledge types, we will briefly overview knowledge representations. Second, we describe a novel cognitive tool designed to aid in knowledge elicitation and organization for instructional purposes ö specifically geared for intelligent tutoring system development. Our aim for this tool, embodied in a program called DNA (Decompose, Network, Assess), is to increase the efficiency of creating the expert model, often referred to as the bottleneck in developing intelligent instructional systems. Third, we present an exploratory test of the tool's efficacy. Specifically, we used DNA with three statistical experts to explicate their knowledge structures related to measures of central tendency in statistics. In short, we found that DNA shows promise as a functionally feasible program. DNA was able to effectively elicit relevant information, commensurate with a benchmark system, generating a starting curriculum upon which to build instruction. The initial elicitation was achieved in hours compared to months for conventional elicitation procedures. (
