Designed for the full-time, professional trainer, this manual is intended for use as a resource in conducting a short course for occasional instructors in the fundamentals of training. It is written in a modular format so that users can select those modules, or parts of modules, that meet the specific needs of their target audience. Trainer's outlines are provided for half-day, one-day, and the complete two-day courses. The introductory chapter discusses the need for training the occasional trainer. Each of the following eight chapters deals with an individual concept or aspect of training: defining the audiovisual aids, evaluation of group dynamics, and trainer styles. In each chapter are an instructor's guide and a course guide. The instructor's guide contains background information, theory, and examples. Contents of the course guide include a sheet detailing purpose, module objective, time required, suggested audience, lists of text and reference material, equipment and supplies, as well as training methods, lecture notes (a detailed outline with suggested exercises and activities) and handouts.
