University students from five classes were randomly assigned to seeing either a movie on AIDS or a movie on first aid. Six weeks later, both groups of students filled out a questionnaire measuring their knowledge of AIDS, attitudes toward AIDS, and attitudes toward homosexuals. In general, the differences between the two groups on the knowledge and attitudes measures were slight. In particular, there was little effect on social attitudes. The showing of one educational movie on AIDS (particularly the movie that was used in this experiment) appears to be insufficient to educate students on this issue.
