Although there is great debate about how work is changing, there is a clear consensus that changes are fundamental and ongoing. The Changing Nature of Work examines the evidence for change in the world of work. The committee provides a clearly illustrated framework for understanding changes in work and these implications for analyzing the structure of occupations in both the civilian and military sectors. This volume explores the increasing demographic diversity of the workforce, the fluidity of boundaries between lines of work, the interdependent choices for how work is structured-and ultimately, the need for an integrated systematic approach to understanding how work is changing. The book offers a rich array of data and highlighted examples on: Markets, technology, and many other external conditions affecting the nature of work. Research findings on American workers and how they feel about work. Downsizing and the trend toward flatter organizational hierarchies. Autonomy, complexity, and other aspects of work structure. The committee reviews the evolution of occupational analysis and examines the effectiveness of the latest systems in characterizing current and projected changes in civilian and military work. The occupational structure and changing work requirements in the Army are presented as a case study.

The archer stands and pulls back the bow, visualizing the path of the arrow to the target. Does this mental exercise enhance performance? Can we all use such techniques to improve performance in our daily lives? In the Mind's Eye addresses these and other intriguing questions. This volume considers basic issues of performance, exploring how techniques for quick learning affect long-term retention, whether an expert's behavior can serve as a model for beginners, if team performance is the sum of individual members' performances, and whether subliminal learning has a basis in science. The book also considers meditation and some other pain control techniques. Deceit and the ability to detect deception are explored in detail. In the area of self-assessment techniques for career development, the volume evaluates the widely used Myers-Briggs Type Indicator.

Education is a hot topic. From the stage of presidential debates to tonight's dinner table, it is an issue that most Americans are deeply concerned about. While there are many strategies for improving the educational process, we need a way to find out what works and what doesn't work as well. Educational assessment seeks to determine just how well students are learning and is an integral part of our quest for improved education. The nation is pinning greater expectations on educational assessment than ever before. We look to these assessment tools when documenting whether students and institutions are truly meeting education goals. But we must stop and ask a crucial question: What kind of assessment is most effective? At a time when traditional testing is subject to increasing criticism, research suggests that new, exciting approaches to assessment may be on the horizon. Advances in the sciences of how people learn and how to measure such learning offer the hope of developing new kinds of assessments-assessments that help students succeed in school by making as clear as possible the nature of their accomplishments and the progress of their learning. Knowing What Students Know essentially explains how expanding knowledge in the scientific fields of human learning and educational measurement can form the foundations of an improved approach to assessment. These advances suggest ways that the targets of assessment-what students know and how well they know it-as well as the methods used to make inferences about student learning can be made more valid and instructionally useful. Principles for designing and using these new kinds of assessments are presented, and examples are used to illustrate the principles. Implications for policy, practice, and research are also explored. With the promise of a productive research-based approach to assessment of student learning, Knowing What Students Know will be important to education administrators, assessment designers, teachers and teacher educators, and education advocates.
The U.S. Department of Defense (DoD) faces short-term and long-term challenges in selecting and recruiting an enlisted force to meet personnel requirements associated with diverse and changing missions. The DoD has established standards for aptitudes/abilities, medical conditions, and physical fitness to be used in selecting recruits who are most likely to succeed in their jobs and complete the first term of service (generally 36 months). In 1999, the Committee on the Youth Population and Military Recruitment was established by the National Research Council (NRC) in response to a request from the DoD. One focus of the committee's work was to examine trends in the youth population relative to the needs of the military and the standards used to screen applicants to meet these needs. When the committee began its work in 1999, the Army, the Navy, and the Air Force had recently experienced recruiting shortfalls. By the early 2000s, all the Services were meeting their goals; however, in the first half of calendar year 2005, both the Army and the Marine Corps experienced recruiting difficulties and, in some months, shortfalls. When recruiting goals are not being met, scientific guidance is needed to inform policy decisions regarding the advisability of lowering standards and the impact of any change on training time and cost, job performance, attrition, and the health of the force. Assessing Fitness for Military Enlistment examines the current physical, medical, and mental health standards for military enlistment in light of (1) trends in the physical condition of the youth population; (2) medical advances for treating certain conditions, as well as knowledge of the typical course of chronic conditions as young people reach adulthood; (3) the role of basic training in physical conditioning; (4) the physical demands and working conditions of various jobs in today's military services; and (5) the measures that are used by the Services to characterize an individual's physical condition. The focus is on the enlistment of 18- to 24-year-olds and their first term of service.
Recruiting an all-volunteer military is a formidable task. To successfully enlist one eligible recruit, the Army must contact approximately 120 young people. The National Research Council explores the various factors that will determine whether the military can realistically expect to recruit an adequate fighting force-one that will meet its upcoming needs. It also assesses the military's expected manpower needs and projects the numbers of youth who are likely to be available over the next 20 years to meet these needs. With clearly written text and useful graphics, Attitudes, Aptitudes, and Aspirations of American Youth offers an overview of important issues for military recruiters, touching on a number of important topics including: sex and race, education and aptitude, physical and moral attributes, and military life and working conditions. In addition, the book looks at how a potential recruit would approach the decision to enlist, considering personal, family, and social values, and the options for other employment or college. Building on the need to increase young Americans' "propensity to enlist," this book offers useful recommendations for increasing educational opportunities while in the service and for developing advertising strategies that include concepts of patriotism and duty to country. Of primary value to military policymakers, recruitment officers, and analysts, Attitudes, Aptitudes, and Aspirations of American Youth will also interest social scientists and policy makers interested in youth trends.
Researchers, historians, and philosophers of science have debated the nature of scientific research in education for more than 100 years. Recent enthusiasm for "evidence-based" policy and practice in educationâ€"now codified in the federal law that authorizes the bulk of elementary and secondary education programsâ€"have brought a new sense of urgency to understanding the ways in which the basic tenets of science manifest in the study of teaching, learning, and schooling. Scientific Research in Education describes the similarities and differences between scientific inquiry in education and scientific inquiry in other fields and disciplines and provides a number of examples to illustrate these ideas. Its main argument is that all scientific endeavors share a common set of principles, and that each fieldâ€"including education researchâ€"develops a specialization that accounts for the particulars of what is being studied. The book also provides suggestions for how the federal government can best support high-quality scientific research in education.
The development of technologies to modify natural human physical and cognitive performance is one of increasing interest and concern, especially among military services that may be called on to defeat foreign powers with enhanced warfighter capabilities. Human performance modification (HPM) is a general term that can encompass actions ranging from the use of "natural" materials, such as caffeine or khat as a stimulant, to the application of nanotechnology as a drug delivery mechanism or in an invasive brain implant. Although the literature on HPM typically addresses methods that enhance performance, another possible focus is methods that degrade performance or negatively affect a military force's ability to fight. Advances in medicine, biology, electronics, and computation have enabled an increasingly sophisticated ability to modify the human body, and such innovations will undoubtedly be adopted by military forces, with potential consequences for both sides of the battle lines. Although some innovations may be developed for purely military applications, they are increasingly unlikely to remain exclusively in that sphere because of the globalization and internationalization of the commercial research base. Based on its review of the literature, the presentations it received and on its own expertise, the Committee on Assessing Foreign Technology Development in Human Performance Modification chose to focus on three general areas of HPM: human cognitive modification as a computational problem, human performance modification as a biological problem, and human performance modification as a function of the brain-computer interface. Human Performance Modification: Review of Worldwide Research with a View to the Future summarizes these findings.
Total quality management (TQM), reengineering, the workplace of the twenty-first century--the 1990s have brought a sense of urgency to organizations to change or face stagnation and decline, according to Enhancing Organizational Performance. Organizations are adopting popular management techniques, some scientific, some faddish, often without introducing them properly or adequately measuring the outcome. Enhancing Organizational Performance reviews the most popular current approaches to organizational change--total quality management, reengineering, and downsizing--in terms of how they affect organizations and people, how performance improvements can be measured, and what questions remain to be answered by researchers. The committee explores how theory, doctrine, accepted wisdom, and personal experience have all served as sources for organization design. Alternative organization structures such as teams, specialist networks, associations, and virtual organizations are examined. Enhancing Organizational Performance looks at the influence of the organization's norms, values, and beliefs--its culture--on people and their performance, identifying cultural "levers" available to organization leaders. And what is leadership? The committee sorts through a wealth of research to identify behaviors and skills related to leadership effectiveness. The volume examines techniques for developing these skills and suggests new competencies that will become required with globalization and other trends. Mergers, networks, alliances, coalitions--organizations are increasingly turning to new intra- and inter-organizational structures. Enhancing Organizational Performance discusses how organizations cooperate to maximize outcomes. The committee explores the changing missions of the U.S. Army as a case study that has relevance to any organization. Noting that a musical greeting card contains more computing power than existed in the entire world before 1950, the committee addresses the impact of new technologies on performance. With examples, insights, and practical criteria, Enhancing Organizational Performance clarifies the nature of organizations and the prospects for performance improvement. This book will be important to corporate leaders, executives, and managers; faculty and students in organizational performance and the social sciences; business journalists; researchers; and interested individuals.

This book describes and evaluates existing models of human performance and their use in the design and evaluation of new human-technology systems. Its primary focus is on the modeling of system operators who perform supervisory and manual control tasks. After an introduction on human performance modeling, the book describes information processing, control theory, task network, and knowledge-based models. It explains models of human performance in aircraft operations, nuclear power plant control, maintenance, and the supervisory control of process control systems, such as oil refineries. The book concludes with a discussion of model parameterization and validation and recommends a number of lines of research needed to strengthen model development and application.
This book identifies areas that represent new needs and opportunities for human factors research in the coming decades. It is forward-looking, problem oriented, and selectively focused on national or global problems, including productivity in organizations, education and training, employment and disabilities, health care, and environmental change; technology issues, including communications technology and telenetworking, information access and usability, emerging technologies, automation, and flexible manufacturing, and advanced transportation systems; and human performance, including cognitive performance under stress and aiding intellectual work.
Volume II covers a number of measurement and analytical issues in greater technical detail, including: range restriction adjustments, methods for evaluating multiple sources of error in measurement, comparing alternative measures of performance, and strategies for clustering military occupations.
