Despite the current need for reliable and valid test instruments to monitor the sign language acquisition of Deaf children in different countries, very few tests offering strong evidence for their psychometric properties are commercially available. A German Sign Language (DGS) test that focuses on linguistic structures acquired in preschool- and school-aged children (4-8 years old) is urgently needed. The present study uses as a template a test which has sound psychometric properties and has been standardized on another sign language as a starting point for tests of sign languages that are less documented, such as DGS.This book makes a novel contribution to the field by examining linguistic, cultural, methodological, and theoretical issues in the process of the adaptation from the source language test to the target language test, and by providing a model for future test adaptations. It also includes concrete steps for the test development and adaptation process.Adaptation and Evaluation of a German Sign Language Test addresses students and researchers alike who are involved in sign language test development and adaptation. It also provides a comprehensive summary in German. |

Sommario/riassunto |
|
The book is divided in two parts, to supply first the basic elements of the language, with short but complete explanations of terms, methods and theories; and then to describe the present status of studies on the processes by which organic molecules aggregate to form observable bodies and to determine their physical and chemical properties. - ;This book is divided in two parts. Part I provides a brief but accurate summary of all the basic ideas, theories, methods, and conspicuous results of structure analysis and molecular modelling of the condensed phases of organic compounds: quantum chemist |
