This volume explores the application of computer simulation technology to measurement issues in education -- especially as it pertains to problem based learning. Whereas most assessments related to problem solving are based on expensive and time consuming measures (i.e., think-aloud protocols or performance assessments that require extensive human rater scoring), this book relies on computerization of the major portion of the administration, scoring, and reporting of problem-solving assessments. It is appropriate for researchers, instructors and graduate students in educational assessment, educational technology, and educational psychology.
The power of modern information systems and information technology (lSIIT) offers new opportunities to rethink, at the broadest levels, existing business strategies, approaches and practices. Over the past decade, IT has opened up new business opportunities, led to the development of new strategic IS and challenged all managers and users of ISIIT to devise new ways to make better use of information. Yet this era which began with much confidence and optimism is now suffering under a legacy of systems that are increasingly failing to meet business needs, and lasting fixes are proving costly and difficult to implement. General management is experiencing a crisis of confidence in their IS functions and in the chiefinformation systems officers who lead them (Earl and Feeney, 1994:11). The concern for chief executive officers is that they are confronting a situation that is seemingly out of control. They are asking, 'What is the best way to rein in these problems and effectively assess IS performance? Further, how can we be certain that IS is adequately adding value to the organisational bottom line?' On the other hand, IS executives and professionals who are responsible for creating, managing and maintaining the organisation's systems are worried about the preparedness of general managers to cope with the growth in new technologies and systems. They see IT having a polarising effect on general managers; it either bedazzles or frightens them (Davenport, 1994: 119).
Cradle-to-grave analyses are becoming the norm, as an increasing amount of corporations and government agencies are basing their procurement decisions not only on initial costs but also on life cycle costs. And while life cycle costing has been covered in journals and conference proceedings, few, if any, books have gathered this information into an
In recent years the increased awareness of environmental issues has led to the development of new approaches to product design, known as Design for Environment and Life Cycle Design. Although still considered emerging and in some cases radical, their principles will become, by necessity, the wave of the future in design. A thorough exploration of t
This book examines the human factors issues associated with the development, testing, and implementation of helmet-mounted display technology in the 21st Century Land Warrior System. Because the framework of analysis is soldier performance with the system in the full range of environments and missions, the book discusses both the military context and the characteristics of the infantry soldiers who will use the system. The major issues covered include the positive and negative effects of such a display on the local and global situation awareness of the individual soldier, an analysis of the visual and psychomotor factors associated with each design feature, design considerations for auditory displays, and physical sources of stress and the implications of the display for affecting the soldier's workload. The book proposes an innovative approach to research and testing based on a three-stage strategy that begins in the laboratory, moves to controlled field studies, and culminates in operational testing.
Computer systems have become an important element of the world economy, with billions of dollars spent each year on development, manufacture, operation, and maintenance. Combining coverage of computer system reliability, safety, usability, and other related topics into a single volume, Computer System Reliability: Safety and Usability eliminates th
These Proceedings provide a general overview as well as detailed information on the developing field of reliability and safety of technical processes in automatically controlled processes. The plenary papers present the state-of-the-art and an overview in the areas of aircraft and nuclear power stations, because these safety-critical system domains possess the most highly developed fault management and supervision schemes. Additional plenary papers covered the recent developments in analytical redundancy. In total there are 95 papers presented in these Proceedings.
