Book Synopsis Implementing and Analyzing Performance Assessments in Teacher Education by : Joyce E. Many
Download or read book Implementing and Analyzing Performance Assessments in Teacher Education written by Joyce E. Many and published by IAP. This book was released on 2017-12-01 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Teacher education has long relied on locally-developed assessments that lack reliability and validity. Rigorous performance-based assessments for preservice teachers have been advanced as one possible way to ensure that all students receive instruction from a high-quality teacher. Recently, performance-based assessments have been developed which focus on the application of knowledge of teaching and learning in a classroom setting. Our book explores factors related to the implementation of teacher performance assessments in varying state and institutional contexts. The contributors, teacher educators from across the country, focus on what was learned from inquiries conducted using diverse methodologies (quantitative, qualitative, self-studies, and mixed methods). Their research encompassed faculty, supervisors, cooperating teachers, and students’ perceptions and concerns of teacher performance assessments, case studies of curricular reform and/or resistance, analyses of experiences and needs as a result of the adoption of such assessments, and examinations of the results of program alignment and reform. The chapters showcase experiences which occurred during high-stakes situations, in implementation periods prior to high-stakes adoption, and in contexts where programs adopted performance assessments as an institutional policy rather than as a result of a state-wide mandate. Endorsements The chapters compiled for Implementing and Analyzing Performance Assessments in Teacher Education edited by Joyce E. Many and Ruchi Bhatnagar, present a thoughtful look at the challenges and solutions embedded in the adoption of teacher performance assessments for preservice teachers. Most chapters feature edTPA, the most commonly used performance assessment now mandated in numerous states and used voluntarily by other programs across the country, and reveal how such assessments shine a bright light on the problems of practice in teacher preparation (stressful timelines, faculty silos, communication with P-12 partners, etc.) when new requirements disrupt the status quo. Each chapter tells a valuable story of performance assessment implementation and approaches that offset compliance in favor of inquiry and educative experiences for candidates and programs alike. Andrea Whittaker, Ph.D edTPA National Director Stanford University Graduate School of Education UL-SCALE Many and Bhatnagar launch the AAPE book series with a curated volume highlighting the contexts in which teacher educators implement and utilize performance assessments in educator preparation. Together, the chapters present research from various viewpoints—from candidates, faculty, university supervisors, and clinical partners—using diverse methodologies and approaches. The volume contributes significantly to the program assessment research landscape by providing examples of how performance assessments inform preparation at the intersection of praxis and research, and campus and field. These chapters provide a critical foundation for teacher educators eager to leverage performance assessments to improve their programs. Diana B. Lys, EdD.

Book Synopsis Mastering Distributed Tracing by : Yuri Shkuro
Download or read book Mastering Distributed Tracing written by Yuri Shkuro and published by Packt Publishing Ltd. This book was released on 2019-02-28 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand how to apply distributed tracing to microservices-based architectures Key FeaturesA thorough conceptual introduction to distributed tracingAn exploration of the most important open standards in the spaceA how-to guide for code instrumentation and operating a tracing infrastructureBook Description Mastering Distributed Tracing will equip you to operate and enhance your own tracing infrastructure. Through practical exercises and code examples, you will learn how end-to-end tracing can be used as a powerful application performance management and comprehension tool. The rise of Internet-scale companies, like Google and Amazon, ushered in a new era of distributed systems operating on thousands of nodes across multiple data centers. Microservices increased that complexity, often exponentially. It is harder to debug these systems, track down failures, detect bottlenecks, or even simply understand what is going on. Distributed tracing focuses on solving these problems for complex distributed systems. Today, tracing standards have developed and we have much faster systems, making instrumentation less intrusive and data more valuable. Yuri Shkuro, the creator of Jaeger, a popular open-source distributed tracing system, delivers end-to-end coverage of the field in Mastering Distributed Tracing. Review the history and theoretical foundations of tracing; solve the data gathering problem through code instrumentation, with open standards like OpenTracing, W3C Trace Context, and OpenCensus; and discuss the benefits and applications of a distributed tracing infrastructure for understanding, and profiling, complex systems. What you will learnHow to get started with using a distributed tracing systemHow to get the most value out of end-to-end tracingLearn about open standards in the spaceLearn about code instrumentation and operating a tracing infrastructureLearn where distributed tracing fits into microservices as a core functionWho this book is for Any developer interested in testing large systems will find this book very revealing and in places, surprising. Every microservice architect and developer should have an insight into distributed tracing, and the book will help them on their way. System administrators with some development skills will also benefit. No particular programming language skills are required, although an ability to read Java, while non-essential, will help with the core chapters.

Book Synopsis Technical Markets Indicators by : Richard J. Bauer
Download or read book Technical Markets Indicators written by Richard J. Bauer and published by John Wiley & Sons. This book was released on 1998-11-26 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of technical market indicators has long been a controversial subject, highly regarded by some and treated with great skepticism by others. Yet, the number of indicators-and the number of individual investors and finance professionals using them-continues to grow. Now, more than ever, there is an urgent need for objective testing to determine the validity of these indicators. Technical Market Indicators is a unique study of the performance of many of the most widely used technical analysis indicators. The authors explore in an unbiased, rigorous manner whether these indicators consistently perform well or fail to do the job. They explain which indicators work best and why, providing a clear picture of what the investor is likely to experience when using technical analysis. Unlike other books on the subject, Technical Market Indicators provides a comprehensive testing of indicators that uses a large sample of stocks over a twelve-year time period, encompassing varying market conditions. Instead of using the traditional technical analysis charts, this detailed analysis takes a different approach, calculating numbers based on various relationships and letting the numbers dictate the decisions. This allows the investor to use technical methods without ever consulting a chart. From an objective standpoint, the authors address both the pro and con arguments of using technical analysis and attempt to shed additional light onto the controversy through their systematic testing. They also alert the investor to the many different issues that must be addressed when using technical indicators, including performance measurement criteria, consistency of results, combining indicators, portfolio considerations, and leveraging. This indispensable resource features: * Comprehensive testing of sixty different technical indicators, fully described, including Trading Band Crossover, Relative Strength Peaks, Random Walk Breakout, Candle Belt Hold, and Volume Trend * An explanation of the underlying concepts behind the indicators and their methods of calculation * In-depth results of tests on each individual indicator, with over 250 pages of detailed tables * An examination of trading rules that combine two or more indicators and a report of a sampling of the best combinations * An annotated bibliography. For those new to technical analysis or for the experienced analyst looking for some fresh angles on the subject, this one-of-a-kind resource is the only one you'll need to navigate the increasingly complex maze of technical market indicators. Can technical analysis be used as an effective tool to enhance investment performance? This question is currently on the minds of many investors and traders. The answer can be found in this invaluable, comprehensive resource, which provides a detailed analysis of the most commonly used indicators, explaining in detail which indicators seem to work best, why, under what conditions, and with which kinds of financial instruments. "Do technical market indicators provide useful information to the stock trader or is it impossible to beat a buy and hold strategy? Bauer and Dahlquist tackle this controversy by rigorously testing 60 indicators on 878 stocks over a 12-year period. Their explanations of the indicators, the testing process, and the results are clear and concise. The 12 major conclusions based on this extensive research will provide the reader with plenty of opportunities to follow Bauer and Dahlquist's final advice: 'Keep learning and keep thinking.

A new chapter then looks at new and advanced models of DEA, including super-efficiency, congestion DEA, network DEA, and dynamic network models. Mathematical formulations of various DEA models are placed in end-of-chapter appendices. Section II then looks at health care applications within particular settings, chapter-by-chapter, including hospitals, physician practices, nursing homes and health maintenance organizations (HMOs). Other chapters then explore home health care and home health agencies; dialysis centers, community mental health centers, community-based your services, organ procurement organizations, aging agencies and dental providers; DEA models to evaluate provider performance for specific treatments, including stroke, mechanical ventilation and perioperative services. A new chapter then examines international-country-based applications of DEA in health care in 16 different countries, along with OECD and multi-country studies. Most of the existing chapters in this section were expanded with recent applications. Included with the book is online access to a learning version of DEA Solver software, written by Professor Kaoru Tone, which can solve up to 50 DMUs for various DEA models listed in the User’s Guide at the end of the book.
