In our booktalk podcasting assignment, I've been working with teachers and students on how to "sell" a book that they would recommend to other students. During the college football season, the TV was on at home more than I would like. One thing our family ended up doing was talking about funny ads. Now that we can play them on the Droid, we can look up and share a funny commercial with each other whenever we feel like it. We all laughed at the Piggy Geico commercial, and then I had to revisit one of my favorites, the Old Spice commercials, which Solana thought were hilarious.
Our enjoyment of the commercials made me think there must be a way to bring in the creativity and humour of advertising to help students write better leads for their booktalks. One of the teachers I'm working with thought we could introduce the different types of advertising (bandwagon, etc.) as a springboard for ideas. Although the main goal is improving student writing, looking at persuasive techniques in advertising is also an important lesson in critical media literacy.
I haven't found any great lists of advertising techniques for use in the classroom online, although this site's list of examples does use visual cues. My favorite resource so far is a lesson on persuasive writing from readwritethink that uses a more sophisticated description of persuasive rhetoric that is used in advertising or any persuasive argument. It might be adaptable for a younger age group and for the booktalk assignment.
