Ralls' Introduction to Materials Science and Engineering is intended for students who want to learn about the nature of solid substances and, especially, for beginning engineering students who are making their first serious contact with the structure and properties of real solids. It represents, clearly and logically, the chemical and physical principles on which the properties of materials depend. The basic relationships introduced in general chemistry and physics courses are reviewed and extended in order to permit the student to relate the properties of ceramic, metallic, and polymeric solids to their internal structure and external environment.

Measurement and Evaluation in Human Performance, Third Edition, offers unmatched, in-depth instruction in measurement and evaluation techniques. Thoroughly revised and updated, the third edition features a new section on epidemiology and further develops international perspectives. This edition also features improved readability in measurement statistics and enhanced efficiency in solving measurement and evaluation problems through the use of the Statistical Package for the Social Sciences (SPSS). 
Additional features that are new to this edition:
-Revised first chapter that lays the groundwork for improved learning throughout the text
-Inclusion of a specific downloadable data set that is used as an example in many chapters
-Removal of outdated and complicated statistical techniques, eliminating the need for a background in higher-level mathematics
-Additional computer tasks in each chapter that tie earlier learning to specific applications 
-Decision scenarios similar to those made by human performance professionals to help students apply decision making skills to practical, real-life problems The text also increases the number of problem sets and places a greater emphasis on student-friendly learning through its learning aids, including chapter objectives, measurement and evaluation challenges, highlight features, mastery items, and new computer tasks for each chapter. Measurement and Evaluation in Human Performance, Third Edition, will appeal to students by engaging them in the material to increase their comprehension, and to professionals through its depth of information and ease in locating it. 
Includes an online study guide!To assist students using the text, Measurement and Evaluation in Human Performance, Third Edition, has a companion online student study guide that allows students to interactively practice, review, and develop their understanding of measurement and evaluation processes so that they can make strong grades and valid decisions. Students will receive free access to the study guide with the purchase of a new text, or it may be purchased as a separate componentThe online study guide is designed to help students learn, understand, and practice the main concepts of each chapter. Students will find selected answers to mastery items from the text, homework problems, selected homework answers, data matrixes to download, and multiple choice quizzes designed to test their knowledge of the textbook material. They will also find lecture outlines created by the authors to help them learn the key concepts, as well as links to related sites on the Web and a variety of test tips.
