This guide provides a practical explanation of cognitive type theory and learning style that will help teachers meet students' needs and discover their own strengths as teachers and colleagues. The introduction provides an overview of the book from the perspective of a high school classroom teacher. Part One introduces the theory of psychological type preferences developed by Carl Jung and discusses the use of the Myers-Briggs Type Indicator in identifying people's preferences for extroversion, introversion, sensing, intuition, thinking, feeling, judging, and perceiving. These eight preferences are discussed in the context of teaching and learning. A case study accompanies the explanation of each preference and shows how that preference typically influences classroom practice. Part Two examines the issues arising from the study and application of type, including the dangers of labeling. The appendix includes a glossary and "OPTIONS," an instrument for determining type preferences for adolescents. (JLS)
