    Abstract
    Describes an experiment using 48 sixth-grade students to compare retrieval techniques using the print and CD-ROM versions of Compton's Encyclopedia. Four queries of defferent complexity (measured by the numer of terms present) were searched by the students after a short training session. The searches were timed and the retrieval steps and search terms were noted. The searches were no faster on the CD-ROM than the print version, but in both cases time was related directly to the number of terms involved. The students coped well with the CD-ROM interface and its several retrieval paths

    Abstract
    Tests were carried out on 120 grade 6 students to compare Compton's Multimedia Encyclopedia on CD-ROM and its printe equivalent in terms of students' ability to recall information and to draw inferences from it. Between-subject varaibles were 3 presentation conditions (printed text with illustrations, text-on-screen, and multimedia-text, still images, and animation) and a retrieval condition (topic retrieved before viewing / topic presented without retrieval). Within-subject variables were text complexity (complex or simple), text type (descriptive or procedural), and measure (propositions recalled versus propositions inferred). Presentation conditions produced no significant main effect although text-on-screen resulted in somewhat higher recall and multimedia resulted in somewhat higher inference scores. Multimedia had the greatest effect in the case of simple topics, and especially the simple procedural topic

    Abstract
    Reports the results from the 2nd phase of a cognitive study of multimedia and its effect on children's learning. A sample of 12 year old primary schools viewed a procedural text that included a 4 sequence animation with captions on how to find south using the sun's shadow, adapted from Compton's Mutlimedia Encyclopedia using Apple QuickTime. The children were divided into 4 grouos; text plus animation, text plus catptions plus animation; and caption with animation. They were then asked to undertake to recall in their own words what they had learned, and also to enact how they would find south usng a specially designed model. No significant differences were found among the groups regarding literal recall of what they had read and seen, or in their ability to draw inferences from it. The children in the text plus animation and captions groups, however, were more successful at identifying the major steps in the procedure and at enhancing that procedure whereas the children who read the text only experienced the most difficulty in performing the procedure
