This book introduces computer-based testing, addressing both nontechnical and technical considerations. The material is oriented toward practitioners and graduate students. The practical emphasis will be useful to measurement professionals who are or will be responsible for implementing a computerized testing program. The instructional information is also designed to be suitable for a one-semester graduate course in computerized testing in an educational measurement or quantitative methods...

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 175.A Continental Plate Boundary offers in one place the most comprehensive, up-to-date knowledge for researchers and students to learn about the tectonics and plate dynamics of the Pacific-Australian continental plate boundary in South Island and about the application of modern geological and geophysical methods. It examines what happens when convergence and translation occur a...

Atlantis the Great Flood and the Asteroid examines the evidence for an asteroid impact in early human prehistory which interrupted the progression of human development. It considers whether a large asteroid caused the Earth to shift its axis the Great Flood a Mass Extinction Event and possibly sank the island of Atlantis right where Plato said it was. Clues come from geology physics archeology paleontology documented sources and more.

Over the course of ten years, this extensive qualitative study focused on the academic resilience phenomenon. The research delves into the educational resilience experiences of fifty low socioeconomic students of color from a variety of racial and ethnic backgrounds. In addition to chronicling specific protective factors and processes active in the students' lives, several symbiotic relationships between groups of protective factors are documented and explored. A Resilience Cycle ...

A must-have introduction to this fundamental driver of the climate systemThe Global Carbon Cycle is a short introduction to this essential geochemical driver of the Earth's climate system, written by one of the world's leading climate-science experts. In this one-of-a-kind primer, David Archer engages readers in clear and simple terms about the many ways the global carbon cycle is woven into our climate system. He begins with a concise overview of the subj...

The advent of accessible student computing packages has meant that geophysics students can now easily manipulate datasets and gain first-hand modeling experience – essential in developing an intuitive understanding of the physics of the Earth. Yet to gain a more in-depth understanding of physical theory, and to develop new models and solutions, it is necessary to be able to derive the relevant equations from first principles. This compact, handy book fills a gap left by most modern geophys...

The goal of this guide and manual is to provide a practical and brief overview of the theory on computerized adaptive testing (CAT) and multistage testing (MST) and to illustrate the methodologies and applications using R open source language and several data examples. Implementation relies on the R packages catR and mstR that have been already or are being developed by the first author (with the team) and that include some of the newest research algorithms on the topic.The book co...

This book describes how to use test equating methods in practice. The non-commercial software R is used throughout the book to illustrate how to perform different equating methods when scores data are collected under different data collection designs, such as equivalent groups design, single group design, counterbalanced design and non equivalent groups with anchor test design. The R packages equate, kequate and SNSequate, among others, are used to practically illustrate the different meth...

In this tribute to Benjamin Wright, former students and colleagues recall the foundational contributions he made to the theory and practice of measurement in a career spanning over five decades. Wright is recognized as the foremost proponent of the psychometric approach of Georg Rasch, a Danish mathematician, whose ideas continue to provoke controversy. Wright’s colleagues and students, and students of their students, are leaders in educational research and practice around the world. This ...

This book summarizes the international evidence on methodological issues in standard setting in education. By critically discussing the standard-setting practices implemented in the Nordic countries and by presenting new methodological approaches, it offers fresh perspectives on the current research.Standard setting targets crucial societal objectives by defining educational benchmarks at different achievement levels, and provides feedback to policy makers, schools and teachers abo...

Fluid-aided mass transfer and subsequent mineral re-equilibration are the two defining features of metasomatism and must be present in order for metamorphism to occur. Coupled with igneous and tectonic processes, metasomatism has played a major role in the formation of the Earth’s continental and oceanic crust and lithospheric mantle as well as in their evolution and subsequent stabilization. Metasomatic processes can include ore mineralization, metasomatically induced alteration of oceani...

The goal of this book is to emphasize the formal statistical features of the practice of equating, linking, and scaling. The book encourages the view and discusses the quality of the equating results from the statistical perspective (new models, robustness, fit, testing hypotheses, statistical monitoring) as opposed to placing the focus on the policy and the implications, which although very important, represent a different side of the equating practice.The book contributes to esta...
