The Age of STEM


Book Description

Across the world STEM (learning and work in Science, Technology, Engineering and Mathematics) has taken central importance in education and the economy in a way that few other disciplines have. STEM competence has become seen as key to higher productivity, technological adaptation and research-based innovation. No area of educational provision has a greater current importance than the STEM disciplines yet there is a surprising dearth of comprehensive and world-wide information about STEM policy, participation, programs and practice. The Age of STEM is a state of the art survey of the global trends and major country initiatives in STEM. It gives an international overview of issues such as: STEM strategy and coordination curricula, teaching and assessment women in STEM indigenous students research training STEM in the graduate labour markets STEM breadth and STEM depth The individual chapters give comparative international analysis as well as a global overview, particularly focusing on the growing number of policies and practices in mobilising and developing talent in the STEM fields. The book will be of particular interest to anyone involved in educational policy, those in education management and leaders in both schooling and tertiary education. It will have a wider resonance among practitioners in the STEM disciplines, particularly at university level, and for those interested in contemporary public policy.

Gender Inclusive Engineering Education


Book Description

Women continue to comprise a small minority of students in engineering education and subsequent employment, despite the numerous initiatives over the past 25 years to attract and retain more women in engineering. This book demonstrates the ways in which traditional engineering education has not attracted, supported or retained female students and identifies the issues needing to be addressed in changing engineering education to become more gender inclusive. This innovative and much-needed work also addresses how faculty can incorporate inclusive curriculum within their courses and programs, and provides a range of exemplars of good practice in gender inclusive engineering education that will be immediately useful to faculty who teach engineering students.




Understanding Student Participation and Choice in Science and Technology Education


Book Description

Drawing on data generated by the EU’s Interests and Recruitment in Science (IRIS) project, this volume examines the issue of young people’s participation in science, technology, engineering and mathematics education. With an especial focus on female participation, the chapters offer analysis deploying varied theoretical frameworks, including sociology, social psychology and gender studies. The material also includes reviews of relevant research in science education and summaries of empirical data concerning student choices in STEM disciplines in five European countries. Featuring both quantitative and qualitative analyses, the book makes a substantial contribution to the developing theoretical agenda in STEM education. It augments available empirical data and identifies strategies in policy-making that could lead to improved participation—and gender balance—in STEM disciplines. The majority of the chapter authors are IRIS project members, with additional chapters written by specially invited contributors. The book provides researchers and policy makers alike with a comprehensive and authoritative exploration of the core issues in STEM educational participation.




Examination of the U.S. Air Force's Science, Technology, Engineering, and Mathematics (STEM) Workforce Needs in the Future and Its Strategy to Meet Those Needs


Book Description

The Air Force requires technical skills and expertise across the entire range of activities and processes associated with the development, fielding, and employment of air, space, and cyber operational capabilities. The growing complexity of both traditional and emerging missions is placing new demands on education, training, career development, system acquisition, platform sustainment, and development of operational systems. While in the past the Air Force's technologically intensive mission has been highly attractive to individuals educated in science, technology, engineering, and mathematics (STEM) disciplines, force reductions, ongoing military operations, and budget pressures are creating new challenges for attracting and managing personnel with the needed technical skills. Assessments of recent development and acquisition process failures have identified a loss of technical competence within the Air Force (that is, in house or organic competence, as opposed to contractor support) as an underlying problem. These challenges come at a time of increased competition for technical graduates who are U.S. citizens, an aging industry and government workforce, and consolidations of the industrial base that supports military systems. In response to a request from the Deputy Assistant Secretary of the Air Force for Science, Technology, and Engineering, the National Research Council conducted five fact-finding meetings at which senior Air Force commanders in the science and engineering, acquisition, test, operations, and logistics domains provided assessments of the adequacy of the current workforce in terms of quality and quantity.




Fifty Years of Fuzzy Logic and its Applications


Book Description

This book presents a comprehensive report on the evolution of Fuzzy Logic since its formulation in Lotfi Zadeh’s seminal paper on “fuzzy sets,” published in 1965. In addition, it features a stimulating sampling from the broad field of research and development inspired by Zadeh’s paper. The chapters, written by pioneers and prominent scholars in the field, show how fuzzy sets have been successfully applied to artificial intelligence, control theory, inference, and reasoning. The book also reports on theoretical issues; features recent applications of Fuzzy Logic in the fields of neural networks, clustering, data mining and software testing; and highlights an important paradigm shift caused by Fuzzy Logic in the area of uncertainty management. Conceived by the editors as an academic celebration of the fifty years’ anniversary of the 1965 paper, this work is a must-have for students and researchers willing to get an inspiring picture of the potentialities, limitations, achievements and accomplishments of Fuzzy Logic-based systems.
