This workbook introduces key concepts and issues related to the mass media. Students perform activities related to these concepts and issues to understand the part they play in their own lives. The usual format consists of a probe, a lab, a focus, an interface, an investigation, and a simulation. For example, one probe is "What are some qualities of popular taste?" The lab for that probe consists of two exercises which define taste in terms of favorite sandwiches and favored curriculum subjects. The focus applies the findings from the lab exercises to another subject, television shows. The interface section discusses the concept of taste in terms of students' everday activities. The investigation section points out other areas of life where that concept is used. Each student is asked to take a position on the major questions of the unit, and in the simulation section, he considers how his position might work out in practice. The major areas considered in the workbook are: the media and the people, the news media, and mass media in a democratic society. Each of these is broken down into several topics. The book appears suitable for high school students. For teacher's manual see EM 010 735.
