This volume presents current thoughts, research, and findings that were presented at a summit focusing on energy as a cross-cutting concept in education, involving scientists, science education researchers and science educators from across the world. The chapters cover four key questions: what should students know about energy, what can we learn from research on teaching and learning about energy, what are the challenges we are currently facing in teaching students this knowledge, and what needs be done to meet these challenges in the future? Energy is one of the most important ideas in all of science and it is useful for predicting and explaining phenomena within every scientific discipline. The challenge for teachers is to respond to recent policies requiring them to teach not only about energy as a disciplinary idea but also about energy as an analytical framework that cuts across disciplines. Teaching energy as a crosscutting concept can equip a new generation of scientists and engineers to think about the latest cross-disciplinary problems, and it requires a new approach to the idea of energy. This book examines the latest challenges of K-12 teaching about energy, including how a comprehensive understanding of energy can be developed. The authors present innovative strategies for learning and teaching about energy, revealing overlapping and diverging views from scientists and science educators. The reader will discover investigations into the learning progression of energy, how understanding of energy can be examined, and proposals for future directions for work in this arena. Science teachers and educators, science education researchers and scientists themselves will all find the discussions and research presented in this book engaging and informative.

This book grew out of lecture notes for an undergraduate course in plasma physics that has been offered for a number of years at UCLA. With the current increase in interest in controlled fusion and the wide spread use of plasma physics in space research and relativistic as trophysics, it makes sense for the study of plasmas to become a part of an undergraduate student's basic experience, along with subjects like thermodynamics or quantum mechanics. Although the primary purpose of this book was to fulfill a need for a text that seniors or juniors can really understand, I hope it can also serve as a painless way for scientists in other fields-solid state or laser physics, for instance to become acquainted with plasmas. Two guiding principles were followed: Do not leave algebraic steps as an exercise for the reader, and do not let the algebra obscure the physics. The extent to which these opposing aims could be met is largely due to the treatment of a plasma as two interpenetrating fluids. The two-fluid picture is both easier to understand and more accurate than the single-fluid approach, at least for low-density plasma phe nomena."

TO THE SECOND EDITION In the nine years since this book was first written, rapid progress has been made scientifically in nuclear fusion, space physics, and nonlinear plasma theory. At the same time, the energy shortage on the one hand and the exploration of Jupiter and Saturn on the other have increased the national awareness of the important applications of plasma physics to energy production and to the understanding of our space environment. In magnetic confinement fusion, this period has seen the attainment 13 of a Lawson number nTE of 2 x 10 cm -3 sec in the Alcator tokamaks at MIT; neutral-beam heating of the PL T tokamak at Princeton to KTi = 6. 5 keV; increase of average ss to 3%-5% in tokamaks at Oak Ridge and General Atomic; and the stabilization of mirror-confined plasmas at Livermore, together with injection of ion current to near field-reversal conditions in the 2XIIss device. Invention of the tandem mirror has given magnetic confinement a new and exciting dimension. New ideas have emerged, such as the compact torus, surface-field devices, and the EssT mirror-torus hybrid, and some old ideas, such as the stellarator and the reversed-field pinch, have been revived. Radiofrequency heat ing has become a new star with its promise of dc current drive. Perhaps most importantly, great progress has been made in the understanding of the MHD behavior of toroidal plasmas: tearing modes, magnetic Vll Vlll islands, and disruptions.

Plasma processing of semiconductors is an interdisciplinary field requiring knowledge of both plasma physics and chemical engineering. The two authors are experts in each of these fields, and their collaboration results in the merging of these fields with a common terminology. Basic plasma concepts are introduced painlessly to those who have studied undergraduate electromagnetics but have had no previous exposure to plasmas. Unnecessarily detailed derivations are omitted; yet the reader is led to understand in some depth those concepts, such as the structure of sheaths, that are important in the design and operation of plasma processing reactors. Physicists not accustomed to low-temperature plasmas are introduced to chemical kinetics, surface science, and molecular spectroscopy. The material has been condensed to suit a nine-week graduate course, but it is sufficient to bring the reader up to date on current problems such as copper interconnects, low-k and high-k dielectrics, and oxide damage. Students will appreciate the web-style layout with ample color illustrations opposite the text, with ample room for notes. The included CD contains a copy of the book which can be indexed using a Search function, and which can be enlarged on a monitor for a closer look at the diagrams. Sample homework and exam problems can also be found on the CD.

This short book is ideal for new workers in the semiconductor industry who want to be brought up to speed with minimum effort. It is also suitable for Chemical Engineering students studying plasma processing of materials; Engineers, physicists, and technicians entering the semiconductor industry who want a quick overview of the use of plasmas inthe industry.

In recent years, researchers have considerably expanded our understanding of the experiences of students of color and of students who are gay, lesbian, bisexual, transgendered, and questioning (ie. Queer). They have provided us with rich resources for addressing racism and heterosexism; however, few have examined the unique experiences of students who are both queer and of color, and few have examined the heterosexist or white-centered nature of anti-racist or anti-heterosexist education (respectively). What of the students and educators who live and teach at the intersection of race and sexuality? By combining autobiographical accounts with qualitative and quantitative research on queer students of different racial backgrounds, these essays not only trouble the ways we think about the intersections of race and sexuality, they also offer theoretical insights and educational strategies to educators committed to bringing about change.

Due to political pressures, prior to the 1990s little was known about the nature of human foraging adaptations in the deserts, grasslands, and mountains of north western China during the last glacial period. Even less was known about the transition to agriculture that followed. Now open to foreign visitation, there is now an increasing understanding of the foraging strategies which led both to the development of millet agriculture and to the utilization of the extreme environments of the Tibetan Plateau. This text explores the transition from the foraging societies of the Late Paleolithic to the emergence of settled farming societies and the emergent pastoralism of the middle Neolithic striving to help answer the diverse and numerous questions of this critical transitional period.
* Examines the transition from foraging societies of the Late Paleolithic to the emergence of settled farming societies and the emergent pastoralism of the middle Neolithic
* Explores explanatory models for the links between climate change and cultural change that may have influenced the development of millet agriculture
* Reviews the relationship between climate change and population expansions and contraditions during the late Quaternary

So much is expected to prepare today's students for success-academic achievement, career and college readiness, emotional and social competency, just to name a few. At least one in 5 children in the United States has some mental disorder, but few schools have the infrastucture in place to help these children. School counselors can make an enormous positive difference in children's lives. Yet, school counseling programs are in crisis because of undefined roles, skyrocketing student-counselor ratios, and decreasing budgets. Leaders and counselors must move away from outdated roles and embrace school counseling programs that ensure readiness for ALL students. In a succinct question and answer format, the authors provide affordable solutions to the increasingly complex systemic issues facing K-12 schools, students, and school counseling programs.
