Here are some of the key maneuvers you are to practice:
Elaborate the perspective of the rhetor--the rhetor's controlling value (purpose and context)--and his or her text in relation to views the rhetor opposes (opposing controlling values to the author). In supplying a summary that embodies the network of controlling values, you are working to demonstrate understanding of the text;
Discuss who the addressed audience is and why you think so, including the controlling value the rhetor projects the audience to have;
Explain and illustrate why and how the rhetor appeals rhetorically (through ethical, logical, and pathetic appeals) to the addressed audience:
Explain ethical appeal and how the rhetor uses it (intelligence, goodwill toward audience, virtue)
Explain logical appeal and how the rhetor uses it (the different kinds of reasoning--scientific, dialectical, rhetorical, and false)
Use specific textual examples to illustrate each of the writer's points (see Point, Illustration, and Explanation on the Topics for Workshopping Arguments)
