This book is intended for new classroom teachers, including licensed and articled teachers, and those who advise and train them. The section on initial encounters with groups will be valuable to many others who have the same need as teachers to show authority, such as youth group workers and playground supervisors. Workers with adults and youth trainers, as well as teachers, have to arouse the interest of their listeners and communicate interest in them and their efforts. Many of the techniques are also valuable to those dealing with groups of adults—though hopef ully they will not need our advice on dealing with disruption. We have addressed the main text to ‘you’ as theinexperienced practitioner.
