This book is the result of a conference sponsored by the Educational Testing Service and the University of Wisconsin's National Center for Research in Mathematical Sciences Education. The purpose of the conference was to facilitate the work of a group of scholars whose interests included the assessment of higher-order understandings and processes in foundation-level (pre-high school) mathematics. Discussions focused on such issues as the purposes of assessment, guidelines for producing and scoring "real-life" assessment activities, and the meanings of such terms as "deeper and higher-order understanding," "cognitive objectives," and "authentic mathematical activities." Assessment was viewed as a critical component of complex, dynamic, and continually adapting educational systems. During the time that the chapters in this book were being written, sweeping changes in mathematics education were being initiated in response to powerful recent advances in technology, cognitive psychology, and mathematics, as well as to numerous public demands for educational reform. These changes have already resulted in significant reappraisals of what it means to understand mathematics, of the nature of mathematics teaching and learning, and of the real-life situations in which mathematics is useful. The challenge was to pursue assessment-related initiatives that are systematically valid, in the sense that they work to complement and enhance other improvements in the educational system rather than act as an impediment to badly needed curriculum reforms. To address these issues, most chapters in this book focus on clarifying and articulating the goals of assessment and instruction, and they stress the content of assessment above its mode of delivery. Computer- or portfolio-based assessments are interpreted as means to ends, not as ends in themselves. Assessment is conceived as an ongoing documentation process, seamless with instruction, whose quality hinges upon its ability to provide complete and appropriate information as needed to inform priorities in instructional decision making. This book tackles some of the most complicated issues related to assessment, and it offers fresh perspectives from leaders in the field--with the hope that the ultimate consumer in the instruction/assessment enterprise, the individual student, will reclaim his or her potential for self-directed mathematics learning.

First published in 1978, this title examines a phenomenon that relies on many realms of human cognition: language comprehension, memory retrieval, and language generation. Problems in computational question answering assume a new perspective when question answering is viewed as a problem in natural language processing.

Bringing together pathologists, clinicians and diagnostic radiologists to produce a simplified analysis and a unification of the existing concepts in the diagnosis and treatment of diffuse lung diseases, this volume highlights pathological changes and presents the latest diagnostic modalities. Detailed therapeutic strategies are proposed based on epidemiological findings, radiographic manifestations, and the complex pathophysiological basis of each disorder. The result will appeal not only to the sophisticated practitioner but will also provide material that is sufficiently organised and didactic to be used by the young physician.

Deceptively simple and surprisingly addictive, Not Quite What I Was Planning is a thousand glimpses of humanity—six words at a time. One Life. Six Words. What's Yours? When Hemingway famously wrote, "For Sale: baby shoes, never worn," he proved that an entire story can be told using a half dozen words. When the online storytelling magazine SMITH asked readers to submit six-word memoirs, they proved a whole, real life can be told this way too. The results are fascinating, hilarious, shocking, and moving. From small sagas of bittersweet romance ("Found true love, married someone else") to proud achievements and stinging regrets ("After Harvard, had baby with crackhead"), these terse true tales relate the diversity of human experience in tasty bite-sized pieces. From authors Jonathan Lethem and Richard Ford to comedians Stephen Colbert and Amy Sedaris, to ordinary folks around the world, everyone has a six-word story to tell.

This is the second of two volumes that review, for the first time, all major aspects of photorefractive effects and their applications. Photorefractive effects in electro-optic crystals are based on optically induced space-charge fields which ultimately alter the refractive indices by the electro-optic Pockels effect. The fundamental phenomena leading to photoinduced changes of refractive index, the materials requirements and experimental results on a variety of photorefractive materials are discussed and the most recent theoretical models describing these phenomena are presented. Interest in photorefractive materials has increased in recent years mainly because of their potential for nonlinear optical devices and for optical signals processing applications. Most of these applications are reviewed in this volume. The contributions to the two volumes are written by experts on each topic and are intended for scientists and engineers active in the field and for researchers and graduate students entering the field. Over 300 references to original papers on photorefractive and associated phenomena are cited. Volume 1 appeared as Volume 61 of Topics in Applied Physics.
