One of a series of high school level units on business issues, this packet introduces students to a new type of business advertising, "issue ads." This non-product advertising allows a corporation or business organization to express its viewpoint directly to the public. Because this is a complex issue, the unit is recommended for students with some background in business study. A teacher's guide and student materials are provided in two separate sections. Following an overview of activities and objectives, the teacher's guide outlines four daily lessons. Also included in this section are answer keys, suggestions for follow-up activities, background readings, and recommendations for using business professionals as classroom resources. The student materials examine specific issue ads on government regulation, energy, and inflation and the arguments for and against this type of corporate free speech through four learning activities. These activities range from an analytical reading to a legal case study and a research project in which students record issue ads they see and conduct a public opinion survey on the ads. (LP)
