This reference manual is designed for Peace Corps volunteers who are involved in teacher training in developing countries. It is to be used with the Teacher Training Guide that accompanies it. The first chapter discusses differences between the educational systems of the host country and that of the United States. It prepares volunteers for their roles as trainers of teachers by discussing: how to conduct a needs assessment, adult learning styles, designing training programs for teachers, and training, supervision, and observation techniques. Chapter two provides a guide for various aspects of teaching, such as child and adolescent learning, instructional objectives, lesson and unit planning, classroom teaching techniques, materials development, and student assessment and improvement. The final chapter discusses support and networking issues and specific collaboration skills. Each chapter and section presents theoretical and practical information and includes an "Activity Box" that is designed to help the trainer apply ideas presented in the section. The appendix contains a collection of forms that the trainer can use during a training session. (JD)
