This book focuses on the crucial theme of modern test development and analysis, specifically focusing on bridging the gap between theoretical frameworks and practical applications. This resource offers a practical and detailed exploration of psychometric principles, encompassing both classical test theory (CTT)-based item analysis and item response theory (IRT), specifically focusing on the one-parameter model (Rasch model) for test equating. By considering CTT and the more sophisticated Rasch model, the book provides a comprehensive pathway to enhanced measurement accuracy and efficiency in the human sciences. It aims to empower readers with the tools and knowledge necessary to navigate the complexities of test equating, item bank creation, and the implementation of computerized adaptive testing (CAT). It provides historical context for these methodologies and outlines prospects for Rasch research, emphasizing the importance of establishing a common scale for measuring ability.A significant contribution is the introduction of Rasch-GZ, a cutting-edge software developed during the COVID-19 pandemic that incorporates AI-driven assistance and bilingual support, potentially streamlining the calibration process of items within an item bank. The book thoroughly reviews fundamental concepts such as item difficulty and discrimination, ensuring readers grasp the theoretical underpinnings of both CTT and IRT. It delves into various test equating techniques, including Common Item Linking and potentially Common Subject Linking, crucial for maintaining invariance across different test forms within a Standardized Examination. Real-world examples with detailed interpretations serve as a step-by-step guide to these procedures, often relying on anchor items. While implicitly addressing the concept of the norm in the context of standardized examination interpretation, the resource primarily focuses on the application of psychometric software. Access to the student version of Rasch-GZ is provided through code, alongside supplementary video tutorials, facilitating hands-on learning and software mastery.This book could be used by practitioners in the fields of applied linguistics, applied psychology, language testing, education management, and researchers working on language testing methods.

The success of the Internet of Things and rich cloud services have helped create the need for edge computing, in which data processing occurs in part at the network edge, rather than completely in the cloud.  In Edge Computing: A Primer the vision and definition of Edge computing is introduced, as well as several key techniques that enable Edge computing. Then, four applications that benefit from Edge computing are presented as case studies, ranging from smart homes and public safety to medical services, followed by a discussion of several open challenges and opportunities in Edge computing. Finally, several key tools for edge computing such as virtualization and resource management are explained.

Entrusted by the Board of Management of the Pacific Rim Objective Measurement Symposium (PROMS), PROMS2012 is held in Jiaxing, China from August 6-9, 2012. Over the past years, PROMS has been hosted in many parts of the Pacific Rim, in Singapore, Malaysia, Hong Kong, Taiwan and Tokyo, which has greatly promoted the research of and contributed to the development of Rasch Model in one way or another. As early as in 1980s, the ideas and concepts regarding IRT was first introduced into China by Prof. Gui Shichun, my Ph.D supervisor, and it is Prof. Gui who first conducted with great success the ten-year long (1990-1999) Equating Project for Matriculation English Test (MET) in China. MET is the most influential entrance examination for higher education administered annually to over 3.3 million candidates then. The Equating Project won recognition by Charles Alderson and other foreign counterparts during 1990s. Academically, those were Good Old Days for Chinese testing experts and psychometricians. Then for certain reasons, the equating practice abruptly discontinued. Therefore, in China nowadays, the application of IRT-based software like BILOG, Parscale, Iteman 4 and others to real testing problem solving is confined to an extremely small 'band' of people. In this sense, PROMS2012 meets an important need in that it provides an excellent introduction of IRT and its application. And anyone who is seriously interested in research and development in the field of psychometrics or language testing will find such a symposium and related workshops to be an excellent source of information about the application of Rasch Model. PROMS2012 focuses on recent advances in objective measurement and provides an international forum on both the latest research in using Rasch measurement and non-Rasch practice.
