This instructor's manual explains the premise on which the text is based: that ideas on a particular topic are made up of input from several perspectives. The authors disclaim that the manual is telling teachers how to teach the text. Instead, the manual, like the textbook, is a series of "probes": suggestions to stimulate thinking and discussion. It includes eleven possible projects for student completion, like tape recordings and student-made films; at least one probe per selection in the text; an analysis of several sections in the text; discussion questions for each communication approach; tests on the various text units, made up of true-false or multiple-choice questions; a test key; and an author-title index.
