"From MOOCs to autograders to computerized tutors, technologies designed for large-scale learning have never lived up to the hype. Justin Reich once promoted these "transformative" novelties; now he reveals their failures. Successful education reform, he concludes, will focus on incremental institutional change, not the next killer app"--
A leader in educational technology separates truth from hype, explaining what tech can—and can’t—do to transform our classrooms. Proponents of large-scale learning have boldly promised that technology can disrupt traditional approaches to schooling, radically accelerating learning and democratizing education. Much-publicized experiments, often underwritten by Silicon Valley entrepreneurs, have been launched at elite universities and in elementary schools in the poorest neighborhoods. Such was the excitement that, in 2012, the New York Times declared the “year of the MOOC.” Less than a decade later, that pronouncement seems premature. In Failure to Disrupt: Why Technology Alone Can’t Transform Education, Justin Reich delivers a sobering report card on the latest supposedly transformative educational technologies. Reich takes readers on a tour of MOOCs, autograders, computerized “intelligent tutors,” and other educational technologies whose problems and paradoxes have bedeviled educators. Learning technologies—even those that are free to access—often provide the greatest benefit to affluent students and do little to combat growing inequality in education. And institutions and investors often favor programs that scale up quickly, but at the expense of true innovation. It turns out that technology cannot by itself disrupt education or provide shortcuts past the hard road of institutional change. Technology does have a crucial role to play in the future of education, Reich concludes. We still need new teaching tools, and classroom experimentation should be encouraged. But successful reform efforts will focus on incremental improvements, not the next killer app.
From the co-founder of THINX and hellotushy.com, start-ups collectively valued at more than $150 million, comes DISRUPT-HER, a rallying cry for women to radically question the status quo. Miki Agrawal has faced patriarchal pushback, fought girl-on-girl hate, ridden the roller coaster of building businesses as a female CEO, and even overcome an attempt to burn her for witchcraft (figuratively). In order to navigate the complicated--at times maddening--struggles of contemporary femininity, we need an unabashed manifesto for the modern woman that inspires us to move past outrage and take positive steps on the personal, professional, and societal levels. This manifesto galvanizes us to action in 13 major areas of our lives with as much fire power as possible. These are the credos we live by, the advice we give to friends, the tenets we instill in our companies and peers on a daily basis. Stories of badass female movers and shakers are shared in this book too to give you an extra jolt of "I've got this." It's a whole body F*CK YES to your work, your love, your relationships, and your mission--while doing it all authentically, unapologetically, and with full integrity.
Optical Fiber Telecommunications V (A&B) is the fifth in a series that has chronicled the progress in the research and development of lightwave communications since the early 1970s. Written by active authorities from academia and industry, this edition not only brings a fresh look to many essential topics but also focuses on network management and services. Using high bandwidth in a cost-effective manner for the development of customer applications is a central theme. This book is ideal for R&D engineers and managers, optical systems implementers, university researchers and students, network operators, and the investment community. Volume (A) is devoted to components and subsystems, including: semiconductor lasers, modulators, photodetectors, integrated photonic circuits, photonic crystals, specialty fibers, polarization-mode dispersion, electronic signal processing, MEMS, nonlinear optical signal processing, and quantum information technologies. Volume (B) is devoted to systems and networks, including: advanced modulation formats, coherent systems, time-multiplexed systems, performance monitoring, reconfigurable add-drop multiplexers, Ethernet technologies, broadband access and services, metro networks, long-haul transmission, optical switching, microwave photonics, computer interconnections, and simulation tools. Biographical Sketches Ivan Kaminow retired from Bell Labs in 1996 after a 42-year career. He conducted seminal studies on electrooptic modulators and materials, Raman scattering in ferroelectrics, integrated optics, semiconductor lasers (DBR , ridge-waveguide InGaAsP and multi-frequency), birefringent optical fibers, and WDM networks. Later, he led research on WDM components (EDFAs, AWGs and fiber Fabry-Perot Filters), and on WDM local and wide area networks. He is a member of the National Academy of Engineering and a recipient of the IEEE/OSA John Tyndall, OSA Charles Townes and IEEE/LEOS Quantum Electronics Awards. Since 2004, he has been Adjunct Professor of Electrical Engineering at the University of California, Berkeley. Tingye Li retired from AT&T in 1998 after a 41-year career at Bell Labs and AT&T Labs. His seminal work on laser resonator modes is considered a classic. Since the late 1960s, He and his groups have conducted pioneering studies on lightwave technologies and systems. He led the work on amplified WDM transmission systems and championed their deployment for upgrading network capacity. He is a member of the National Academy of Engineering and a foreign member of the Chinese Academy of Engineering. He is a recipient of the IEEE David Sarnoff Award, IEEE/OSA John Tyndall Award, OSA Ives Medal/Quinn Endowment, AT&T Science and Technology Medal, and IEEE Photonics Award. Alan Willner has worked at AT&T Bell Labs and Bellcore, and he is Professor of Electrical Engineering at the University of Southern California. He received the NSF Presidential Faculty Fellows Award from the White House, Packard Foundation Fellowship, NSF National Young Investigator Award, Fulbright Foundation Senior Scholar, IEEE LEOS Distinguished Lecturer, and USC University-Wide Award for Excellence in Teaching. He is a Fellow of IEEE and OSA, and he has been President of the IEEE LEOS, Editor-in-Chief of the IEEE/OSA J. of Lightwave Technology, Editor-in-Chief of Optics Letters, Co-Chair of the OSA Science & Engineering Council, and General Co-Chair of the Conference on Lasers and Electro-Optics.
Strategies for Protecting National Critical Infrastructure Assets eases the research burden, develops investigative protocols, and pulls together data into a comprehensive and practical guide, to help the serious reader understand advanced concepts and techniques of risk assessment with an emphasis on meeting the security needs of the critical national infrastructure. The text is divided into five major sections, which are further broken down by individual chapters, each addressing one element of risk assessment as well as focusing attention on applying the risk assessment methodology to a particular industry. This book establishes a new and acceptable approach for conducting risk assessments in a high-risk world. Helps the reader to understand advanced concepts and techniques of risk assessment Provides a quick, reliable, and practical "briefcase" reference to use in the office as well as on the road Introduces the elements of the risk assessment process by defining its purpose and objectives, describing the behavioural and physical sciences, the techniques employed in the process, and the measurement and evaluation tools and standards used to perform an objective risk assessment.
