Sex Differences in Reading and Math Test Scores of Children - Hoben Thomas - Bog - Springer International Publishing AG - Plusbog.dk

Sex Differences in Reading and Math Test Scores of Children - Hoben Thomas - Bog - Springer International Publishing AG - Plusbog.dk

This open access book examines why reading and math test scores for boys and girls have differed since the origins of testing in the United States. It details the pattern of differences that have remained largely unchanged for more than 100 years in the United States and worldwide. The book explores why boys have modestly larger math test score means than girls, and why girls have far larger reading test score means than boys. Boys have larger test score variances for both tasks. The only data of focus—and thus the only data to be explained—are boys’ and girls’ test score sample means and variances. In addition, the book provides the only coherent theory of gender differences explaining math and reading test score means and variances obtained in observational settings. It develops the simple genetical idea framed within a finite probability mixture model; it provides parameter estimates and displays numerous estimated probability distributions associated with the selected accessible studies chosen for analysis; and it extends the theory and provides explanations for never understood puzzling features of test score data. The book requires no auxiliary sources, although some understanding of random variables and probability theory is required to follow the formalization. It contains all technical details, including the estimation procedure and an R code implementation. Key areas of coverage include:· Extensive literature summary from a unique data inequalities perspective. · Perspective that challenges existing viewpoints on sex differences, falsifying conventional perspectives. · Illustrates probability modeling of psychological data. · Illustrates the failure of conventional statistics to explain data and the need for modeling data. Sex Differences in Reading and Math Test Scores of Children is an invaluable resource for researchers, professors, and graduate students in educational psychology, teaching and teacher education, literacy / language teaching and learning, mathematics education, curriculum studies, developmental psychology, statistics, and all interrelated disciplines.

Mars via the Moon - Erik Seedhouse - Bog - Springer International Publishing AG - Plusbog.dk

MOMENTUM IS BUILDING for a return to the Moon. NASA’s international partners on the International Space Station are in favor of returning to the lunar surface, as are India and China. The horizon goal may be Mars, but the political, funding and the technological and medical infeasibility of such an objective means the next logical step is a return to the Moon. While much has been learned about the Moon over the years, we don’t understand its resource wealth potential and the technologies to exploit those resources have yet to be developed, but there are a number of companies that are developing these capabilities. And, with the discovery of water in the lunar polar regions, plans are in the works to exploit these resources for fuel for transportation operations in cis-lunar space and in low Earth orbit (LEO). The time has come for commercial enterprise to lead the way back to the lunar surface. Embarking on such a venture requires little in the way of new technologies. We don’t need to develop super-fast propulsion systems like those required to get us to Mars safely, nor do we need hundreds of billions of dollars that the experts reckon it will cost to transport humans to the Red Planet. What we do need is a place to test the technologies and deep space experience that will enable us to build a pathway that will lead us to Mars. That place is the Moon and this book explains why.

Wordsearches - Adrian Wallwork - Bog - Springer International Publishing AG - Plusbog.dk

On the train, on the beach, on the sofa ... many people in all parts of the world enjoy doing wordsearches. If you are studying English and want to learn and practise vocabulary related to various topics, then this book is for you! The topics reflect the kinds of everyday conversations that you might have both with native and non-native speakers of English. The topics are also those that are typically tested in English examinations e.g.TOEFL, Cambridge (First Certificate, Advanced), IELTS, and Trinity. Each chapter begins with a list of questions to enable you to have a conversation about a particular topic in various situations: on a social occasion (e.g. a work dinner, a conference lunch, a party); in the classroom during an English lesson; when chatting, either face to face or online; and during an English oral exam. After the list of questions, you will find a Word List associated with the topic and exercises to test your knowledge of less common words. The final aim is then to find the words from the Word List in the related Wordsearch. Easy English! is a series of books to help you learn and revise your English with minimal effort. You can improve your English by: reading texts in English that you might normally read in your own language e.g. jokes, personality tests, lateral thinking games, and wordsearches;doing short exercises to improve specific areas grammar and vocabulary, i.e. the areas that tend to lead to the most mistakes - the aim is just to focus on what you really need rather than overwhelming yourself with a mass of rules, many of which may have no practical daily value.

Scattering Analysis of Periodic Structures using Finite-Difference Time-Domain Method - Khaled Elmahgoub - Bog - Springer International Publishing AG

Scattering Analysis of Periodic Structures using Finite-Difference Time-Domain Method - Khaled Elmahgoub - Bog - Springer International Publishing AG

Periodic structures are of great importance in electromagnetics due to their wide range of applications such as frequency selective surfaces (FSS), electromagnetic band gap (EBG) structures, periodic absorbers, meta-materials, and many others. The aim of this book is to develop efficient computational algorithms to analyze the scattering properties of various electromagnetic periodic structures using the finite-difference time-domain periodic boundary condition (FDTD/PBC) method. A new FDTD/PBC-based algorithm is introduced to analyze general skewed grid periodic structures while another algorithm is developed to analyze dispersive periodic structures. Moreover, the proposed algorithms are successfully integrated with the generalized scattering matrix (GSM) technique, identified as the hybrid FDTD-GSM algorithm, to efficiently analyze multilayer periodic structures. All the developed algorithms are easy to implement and are efficient in both computational time and memory usage. These algorithms are validated through several numerical test cases. The computational methods presented in this book will help scientists and engineers to investigate and design novel periodic structures and to explore other research frontiers in electromagnetics. Table of Contents: Introduction / FDTD Method and Periodic Boundary Conditions / Skewed Grid Periodic Structures / Dispersive Periodic Structures / Multilayered Periodic Structures / Conclusions

Effective Teaching Around the World - - Bog - Springer International Publishing AG - Plusbog.dk

Effective Teaching Around the World - - Bog - Springer International Publishing AG - Plusbog.dk

This open access book brings together theoretical, empirical, methodological, and practical insights from various countries on effective teaching. It particularly focuses on discussing issues pertaining to effective teaching behaviour including definitions and conceptualizations, measurement, differences, and importance to student outcomes from international perspectives. The book will draw upon the rich cultures with diverse contexts involving Asia, Australia, Africa, America, and Europe which serve as the background setting to better understand teaching quality from a wide spectrum of educational systems and performances. It shows that effective teaching behaviour can be conceptualized and operationalized uniformly using specific frameworks and measures, but also addresses some limitations that should be tackled.The book discusses promising ways to measure and compare effective teaching behaviour from classical test theory (CTT) as well as item response theory (IRT) perspectives.It indicates that effective teaching behaviour in diverse countries follows a systematic level of complexity, which provides an avenue for ongoing teacher education and teacher professional development. It discusses the interrelated domains of effective teaching behaviour including contemporary trends of differentiation. The book continues with examining similarities and differences in effective teaching behaviour across countries. It builds on the understanding of cultural traditions across countries as profoundly reflected in the classroom processes.

Friendship 7 - Colin Burgess - Bog - Springer International Publishing AG - Plusbog.dk

Friendship 7 - Colin Burgess - Bog - Springer International Publishing AG - Plusbog.dk

In this spellbinding account of an historic but troubled orbital mission, noted space historian Colin Burgess takes us back to an electrifying time in American history, when intrepid pioneers were launched atop notoriously unreliable rockets at the very dawn of human space exploration. A nation proudly and collectively came to a standstill on the day this mission flew; a day that will be forever enshrined in American spaceflight history. On the morning of February 20, 1962, following months of frustrating delays, a Marine Corps war hero and test pilot named John Glenn finally blazed a path into orbit aboard a compact capsule named Friendship 7. The book’s tension-filled narrative faithfully unfolds through contemporary reports and the personal recollections of astronaut John Glenn, along with those closest to the Friendship 7 story, revealing previously unknown facts behind one of America’s most ambitious and memorable pioneering space missions.
