Middle schoolers study the three types of mass media messages: visual media, written media, and audio media. After a class discussion which has them list examples of each, learners get into pairs and work on analyzing the "Four A's" in different types of media messages. The "Four A's" are; angle, audience, aim, and arrangement. Then, the student pairs come up with their own version of a media message in which they use the "Four A's" as best they can. The instructions, activities, worksheets, and scoring rubric embedded in the plan are among the finest I've seen for a lesson on media. I'd highly recommend the lesson for your young teens!
