| Abstract |
|
Each year over a six-year span, chemistry and biochemistry majors in a chemistry senior seminar completed a survey at the beginning and again at the end of the course on which they responded (agreed, disagreed, were undecided, or didn't care) to a variety of science and society propositions. Groups of 2–4 students were formed based on the students' initial interest in particular propositions. Each group evaluated one proposition, advocated a position on it, and presented it to peers as a Web site and a 15-minute seminar followed by questions and answers. Analysis of 350 pre– and post–response data sets involving a total of 78 different propositions showed that students initially had limited awareness and poor understanding of many societal issues relating to chemistry. Their positions often changed significantly by the end of the course (p ≤ 0.05) for propositions presented by peers, yet students rarely changed positions in response to propositions presented only via a Web site, with no oral presentation. Oral presentations appeared to have a greater influence on students' thinking than material presented only on a Web site.

| Supplement |
A synopsis of the 78 propositions used in the course and statistical analyses of the students' pre- and post-responses to every proposition by section and year are available.
