Explores the sources of beliefs about science-technology-society topics and investigates the degree of ambiguity harbored by four different response modes, such as Likert-type, written paragraph, semistructured interview, and empirically developed multiple choice. Finds that mass media have a greater impact than science classes. (Author/YP)

After discussing task-specific information and form/content dissociation, presents evidence from training studies which suggests ways in which the form/content distinction might guide researchers in designing diagnostic measures leading to specific instructional strategies based on the diagnostics.
