During the course of investigations on such topics as the instructional styles, interaction patterns and personality characteristics of teachers, the organizational structure of schools, the technology of instruction, and the affective and cognitive growth of students, researchers have developed hundreds of psychological and educational instruments to study teacher and pupil behavior in the classroom. This book is designed to bring before the educational community the instruments used in these studies. The instruments are organized according to who supplies information about whom (about the teacher from the teacher, about the pupil from the teacher, about the teacher from an observer, etc.). The organizational format of the reviews includes: name of instrument, author, type of measure, availability, description, illustration of sample items and response formats, psychometric characteristics, norms, administration and scoring, comments (evaluative remarks about the instrument's useability and psychometric adequacy), and major references. The description, reliability, validity, and comment sections constitute the major parts of each review. The descriptive and psychometric categories provide objective data from which the reader may draw his own conclusions about the adequacy of the measure, while a final, evaluative section presents the author's perception of the instrument's strengths and weaknesses.
