This self-instructional manual offers knowledge and skills needed to make reliable and accurate perceptual evaluations about teacher candidates. The first chapter describes traditional approaches to the study of teacher effectiveness and the problems that necessitate the formulation of new approaches. Chapter Two describes the research and summarizes the perceptual view of effective teaching. The process and rationale for making perceptual inferences are discussed in Chapter Three. Chapter Four contains practice material to be used for skill improvement in making perceptual inferences. Chapter Five contains additional practice materials and the procedure for evaluating responses to human relations incidents. The final chapter discusses the methods for the selection of effective teachers. Instructions for asking teacher candidates to write human relations incidents and a bibliography on the perceptual approach to teacher effectiveness are appended. (Author/CJ)
