This book is designed as an introduction to medical education and is aimed at all teachers in medicine who are actively engaged in the undergraduate, postgraduate or continuing education fields. A medical school or training institution's greatest assets are arguably its teachers. This book expresses the view that all healthcare professionals have the potential of being good teachers and that teaching well is more fun and satisfying than teaching poorly. Poor teachers can become good teachers and good teachers can become excellent teachers. This book is aimed at the individual teacher, clinical supervisor, dean or course organiser and will enable teachers or trainers to fulfil their responsibilities and achieve their full potential.
