This article aims to provide a theoretical framework for computerized adaptive tests (CAT) and item response theory models for polytomous items. Besides that, it aims to introduce the simulation and live CAT software to the related researchers. Computerized adaptive test algorithm, assumptions of item response theory models, nominal response…

This book gives an overview of the state-of-the-art in Technology Enhanced Learning (TEL). It is organized as a collection of 14 research themes, each introduced by leading experts and including references to the most relevant literature on the theme of each cluster. Additionally, each chapter discusses four seminal papers on the theme with expert…

Discusses an algorithm for developing problem solving simulations using microcomputers, and describes both the components of the simulation algorithm and the user interface. Examples of simulation and programming methods are presented. (MBR)

The purpose of this evaluation of DEMOS, a system for decision modeling and uncertainty analysis, was to identify some generic issues of interest in the design of such information systems, obtain insights about the causes of problems in their use, and to suggest hypotheses about how to deal with them. (EM)

This report documents a computer-based gaming system for assessing recognition performance (RECOG). The game management system is programmed in a modular manner to: instruct the student on how to play the game, retrieve and display individual images, keep track of how well individuals play and provide them feedback, and link these components by…

This report documents a computer program for simulation evaluation of item response theory (IRT) ability estimators. This Honeywell DPS version is a very slight modification of the program originally developed in FORTRAN-77 on a DEC VAX 11/780. The model of the world simulated by the program involves a unidimensional test in which the probability…

This report describes the development of the Instructional Support System (ISS), a large-scale, computer-based training system that supports both computer-assisted instruction and computer-managed instruction. Written in the Ada programming language, the ISS software package is designed to be machine independent. It is also grouped into functional…

Presents a classification system of four microcomputer simulation types developed to evaluate their instructional processes: structured questions and graphics, variable-assignment exercises, diagnostic simulations, and group-interactive simulations. How this taxonomy contributes to three tasks associated with classroom use of software is…

Describes technique involved in designing a clinical simulation problem for the allied health field of respiratory therapy; discusses the structure, content, and scoring categories of the simulation; and provides a sample program which illustrates a programming technique in BASIC, including a program listing and a sample flowchart. (MBR)

Design of computer circuits used to be a pencil and paper task followed by laboratory tests, but logic circuit design can now be done in half the time as the engineer accesses a program which simulates the behavior of real digital circuits, and does all the wiring and testing on his computer screen. A simulated laboratory in digital logic has been…

This document reports on the first year of the STACI (Systems Thinking and Curriculum Innovation) project, a two-year project which is examining the cognitive demands and consequences of using the STELLA (Structural Thinking Experimental Learning Laboratory with Animation) software to teach systems thinking, content knowledge, and problem solving.…

This overview of computer uses in occupational training discusses three computer-based training modes--embedded, stand-alone, and adjunct training. An adjunct training system is described which captures task realism through a simulation to teach the use of a command and control system. A pilot study of this adjunct system's use is described.…

The expert system computer simulation detailed in this report is designed to investigate patterns of valuing in decision-making about dossiers of performance data used in teacher promotion evaluations. The knowledge base for the simulation consists of 111 questions organized into 117 rules. The questions and linked advice were derived from…

Provides a framework for understanding the concept of validity and how it applies to simulation research. Extant tests of validity are discussed in terms of this framework, and a general schema for testing validity is proposed. (MBR)

In providing an alternative view to the previous article by Ward (TM 508 880), the author notes problems associated with adaptive testing, diagnostic testing, testing embedded in instruction, and testing through simulations. (BW)
