ABSTRACT

The general purpose of the Decompose-Network-Assess (DNA) method of cognitive task analysis is to provide an easy procedure for eliciting knowledge and skill elements from experts and represent the diverse kinds of knowledge required to reason and function in any domain. The DNA method is intended to identify a hierarchically structured knowledge base of curriculum elements for instructional and training purposes (Shute, Torreano, & Willis, in press). Its primary goal is to produce the expert model for intelligent instructional systems. The DNA program is still being refined. We believe that it will be a worthwhile tool for analyzing instructional or training requirements for other, more general purposes as well.
