This document is the fifth volume in a set of five Career Education Measurement Handbooks intended to help local education personnel in measurement and evaluation. Divided into seven chapters, this handbook is designed to provide practical guidelines for using observational techniques to take readings of the feelings, perceptions, and reactions of those persons involved or affected by a project. The first chapter provides an introduction and overview of the handbook. Chapter 2 provides some insight as to what can be evaluated. Chapter 3 presents a number of ways for systematically collecting data by observing, interviewing, and gathering data unobtrusively. The fourth chapter presents some ideas and insights to be considered when using the techniques discussed in chapter 3. Chapter 5 discusses ways of organizing, analyzing, and justifying the use of the data collected. Suggestions and exercises are provided in chapter 6 to increase the evaluators's ability to effectively observe and record events. Finally, chapter 7 presents a brief summary of the information contained in this handbook and nine checklists to help the user both review this information and plan systematic observations. A selected bibliography is also included. (BM)
