This book presents one method for identifying mind-sets, learning styles, and motivation patterns, and using the patterns in planning instruction and other helping processes, with the objective of helping people find and use their strengths to ameliorate weaknesses. The approach presented is based on Carl Jung's ideas about psychological types, as made practical through the work of Isabel Briggs Myers. The book includes readings and instructions for activities that explain the theory and offer guidance in making applications of it. It can be used for group or individual study by teachers and other helping professionals, parents, and bosses. The book is divided into two parts. Part 1 has seven chapters on basic applications of type concepts, including the beginning theory needed for guiding sound uses of type. Part 2 has five chapters, one on the deeper aspects of type theory, and four on advanced applications. The twelve chapters are: (1) "People Types and Tiger Stripes"; (2) "Type, Motivation, and Learning Style"; (3) "Using Type Concepts in Planning Instruction"; (4) "Type and Teaching Styles"; (5) "Type is a Four-Letter Word: Uses and Abuses of the MBTI"; (6) "Type and Stereotype"; (7) "Taking Type into Account in Education"; (8) "The Dynamics of the Types"; (9) "Type and Curriculum Reform"; (10) "Developmental Needs and Type Concepts"; (11) "Kinds of Mind"; and (12) "Introducing Type into an Organization." An appendix contains "Introduction to Type" by Isabel Briggs Myers. (TJQ)
