An Exploratory Study of the Effects of Training in Argumentation on Student Opinion Change.
Trew, Marsha Ann
To determine if training in argumentation could affect the bases for student evaluation of communication aimed at changing opinions, students from Michigan State University formed an experimental group (those in an argumentation course) and a control group (those in a business letter writing course). The treatments consisted of four varying message topics, message adequacy (in terms of reasoning, evidence, analysis, and organization), and the credibility of the sources delivering the messages. Both groups were tested at the beginning (Time 1) and end (Time 2) of the fall 1968 school semester. Findings showed that (1) at Time 1, both groups responded more favorably on one of the four topics to high source credibility conditions; (2) at Time 2, the control group did not continue to base opinion change primarily on the credibility of the source; and (3) the experimental group was not capable of expanding its bases on evaluation to include message adequacy. The lack of statistically significant findings was attributed to insufficient research time, to the assumption that the acquisition and use of the principles associated with argumentation occurred simultaneously, and to unstable, internally inconsistent opinion scales.
