This document provides guidance and materials for a seminar on how social media impacts behavior and consumer choices. It discusses the importance of using assigned readings to inform ideas and asking questions to check understanding or request examples and reasons. Students are instructed to find examples from their research on the topic to contribute to the upcoming seminar discussion. The reading materials evaluate three models of media effects: the media-effects model where audiences are passive; the active-audience model where media can change beliefs; and the media-themes model that takes a middle approach.
