This study tested the effects of two instructional aids in a complex, dynamic environment, specifically, a business simulation. Participants studied (1) a "causal map," which depicted key variables in an interconnected network, (2) a textual outline of the same relationships, or (3) no-aid. With the relevant aid still available, the participants…

Incorporating relevant numerical information into decision-making is a fundamental and important aspect of numeracy. However, the process through which weight is assigned to particular numerical values is not well understood. The central theory proposed in this dissertation is that the weight assigned to numerical information may be conceptualized…

A procedure designed to help instructional decision-makers evaluate individual sources of diagnostic information in terms of their functional utility may add a desirable measure of precision to their instructional prescriptions for learners. (Author)

Typically, guidelines for design of interactive multimedia systems have been based on intuitive beliefs of designers rather than being founded on relevant research and theory. As advances in technology create new opportunities for education, it is important to use a range of theoretical perspectives to optimize use of new technology in teaching…

An approach to skills analysis is described in which strategy and processing skills sufficient for task performance are represented as an information-processing routine. Each step in the routine is viewed as a utilization of a processing mechanism or primary process. Definitions of these processes represent hypotheses about the psychological…

Educational development requires management, which is basically decision-making based upon information. Information must be processed, involving movement from its source, analysis, transmission, storage, retrieval, summarization, transformation, and reporting. The regulation of this process is the purview of the information management system…
