This book is a guide for personnel responsible for implementation of a cross-curricular sex education project in schools. It complements and overlaps the contents of the "Teaching Materials" book which contains a set of cross-curricular modules suitable for use in secondary schools. Both books are designed to support other curricular programs, but each one can also stand alone as a contribution to the social education of students. The materials inform young people about the medical ramifications and other consequences of sexual behavior and encourage young people to find time for reflection. It is also hoped that this guide will provide educators effective strategies for coping with the demands of health and social education during a period of curriculum changes. The project incorporates "cross-curricular modules" to allow discussions of sexuality and relationships in various subject areas. The modules provide information and opportunities to explore a variety of topics. Each module, designed to be used by non-health-specialist teachers, is to be delivered in subject time. It provides purposeful activities for the subject course work, includes an element of class feedback for the coordinator, does not demand special skills in sex education, and contains no sensitive material.
