Learning research in visuals and media from education is reviewed, summarized, and extrapolated for the planetarium. Of particular interest is research into the use of cuing, with relevance to the planetarium display. It has been demonstrated that viewers can learn more if they are told about the important concepts and terms before the planetarium show. Researchers from educational fields have shown other ways to increase learning through well-designed visuals. When sophisticated audiovisual technology is used in the planetarium, the planetarian must help the visitor make the technological step. Ten specific research questions are posed for further investigation in the planetarium field, which center on the role of visuals and visual cuing. (Contains 22 references.) (SLD)
