The purposes of Project Understanding were to help participants to: obtain accurate information of human survival issues relating to people, poverty, pollution, and politics; think through the implications of these issues and examine their opinions about them; change their own opinions, attitudes, and behavior; and take effective citizen action. An opinionaire was used. The findings indicate that the multi-media method of television, discussion groups, and study materials is effective in changing expressed opinions about social and political issues. Insofar as the opinionaire was an appropriate measure representative of the content and purpose of the program, the research findings demonstrate that Project Understanding accomplished its purpose to a considerable extent. The tests on the null hypotheses designed to ascertain the representativeness of the experimental group were sustained. The hypotheses that the program series would make no difference in opinions on the various subjects covered were rejected. The fact that there was evidence of opinion change only on those items dealt with directly in the programs and not on the miscellaneous statements adds validity to the study.
