Scaling Methods is written for professionals in the behavioral sciences who analyze data that results from subjective responses. Other books on scaling attitudes or measuring perceptions focus on the psychometrician's view of measurement. This book focuses on the users' view by concentrating on effective ways to analyze data rather than the mathematical details of how each program works. The methods included handle the majority of data analysis problems encountered and are accompanied by a software solution. Each chapter features the theory surrounding that methodology, an example, a real-world application, and a computer solution.This book introduces the major uni- and multi-dimensional scaling method techniques most common in educational, social, and psychological research. Using four primary methods of data collection--ordering, categorical rating, free clustering, and similarity judgments--Scaling Methods, Second Edition explains how such data can be represented in ways that illustrate relationships among the data and help reveal underlying dimensional structures. Each method serves as an independent unit so readers can pick and choose from a variety of easy-to-use procedures and more advanced techniques. The new edition features a new chapter on order analysis and downloadable resources that provide stand-alone, as well as SAS supported demonstrations of multi-dimensional scaling techniques, plus programs to get raw data into matrix form. The text is written for researchers, practitioners, and advanced students in education and the social and behavioral sciences interested in analyzing data resulting from subjective responses, especially in the measurement of attitudes. Each chapter is self-contained making this an excellent resource for use in the classroom or as a self-study tool. A first course in statistics is a helpful prerequisite.

This volume integrates research findings from three multinational studies conducted to examine the impact of children's use of computers in school. Conclusions are drawn from in-depth analyses of trends in more than 20 nations. Its seven authors from four nations were key researchers on these projects. Both a study and a product of the information age, this work is of prime importance to teachers, teacher educators, and school administrators.This work is unique in three important ways:* it presents data gathered in many regions of the world;* many of the authors are well-known and respected for their previous work in educational studies; and* the chapters are designed in such a way that the majority of the book is easily accessible to professionals such as classroom teachers who are interested primarily in findings, results, and outcomes rather than the methodology of the research.
