Something like this:
Name the speaker, the purpose, and the intended audience; then describe how the message was crafted to achieve the purpose. It helps students understand what rhetoric is, and that's a good thing.
The results students produce, however, are often boring:
- The ad shows us attractive cool people using the product, and the intended audience wants to be cool and attractive...
- The ad presents a logical argument on price and value...
- The ad makes us feel afraid of what might happen if we don't buy the product...
Commercials are boring.
I don't ask students to write up rhetorical analyses of commercials because the most visible marketing campaigns often rely on easy rhetorical appeals - making for easy (read boring) papers.
What if, however, our students had to pick marketing material like this?
