This volume of selected readings developed for students and practitioners at various levels of sophistication is intended to be representative of work done to date on interaction analysis. The contents include journal articles, papers read at professional meetings, abstracts of doctoral dissertations, and selections from larger monographs, plus 12 articles written for this book. The introduction by Ned Flanders discusses the book's contents in terms of the historical development of the interaction analysis system. Editors Amidon and Hough provide a preface sketching the three-chapter organization and chapter overviews designed to integrate the contents. Chapter 1 (background and theory) contains six early papers on the theory of social-emotional climate upon which interaction analysis is based. Chapter 2 (explication of the interaction analysis system and empirical validation of the theory) consists of 11 more technical papers dealing with the technique for recording and analyzing the spontaneous classroom verbal behavior of teachers and students and the use of this technique in research on classroom climate and its effects on students. Chapter 3 (application of the system to problems of teacher education) contains 13 papers, most of them reports of research studies measuring the effects of interaction analysis training on the behavior of preservice and inservice teachers. A 185-item bibliography is is included. (JS)
