The introductory section of the first of two related guides provides information that describes and assists in teaching a curriculum on HIV (human immunodeficiency virus) and AIDS (acquired immune deficiency syndrome). The introduction discusses the scope of the problem and includes an overview of the curriculum, a review of teaching strategies, teaching tips, a sample letter to parents, and answers to questions solicited from students. Section 1 of the instructor's guide contains a set of lesson plans that coordinates with information and worksheets from the student guide. The lessons are presented in a suggested sequence that can be used for grades 5, 6, or 7. The six lesson titles and the analogous titles in the student guide are as follows: (1) How Infectious Diseases Spread (What is AIDS?); (2) HIV: An Infectious Disase (Who Has HIV Infection?); (3) HIV: Fact or Fiction (What Does HIV Do to the Body?); (4) The Last Time I Was Sick (What Are the Symptoms of HIV Infection?); (5) Protection against Disease (How Is HIV Infection Spread?); and (6) Saying No (How Can HIV Infection Be Prevented?). Section 2 of the guide contains different types of questions that can be used for evaluation. The appendix provides a listing of additional sources and a glossary of terms from the student guide. (JD)
