- Abstract
- Describes the methodology and reports the results of a study to measure text comprehension by school students when using a variety of media. Four different texts in the printed multi volume Compton's Encyclopedia and its multimedia CD-ROM database equivalent were read by grade 6 (11-12 year old) students who were then asked several multiple choice questions on them. Three groups, print, text on screen and multimedia (text, illustration and video), were asked only to read the texts presented to them. Two additional groups, print and multimedia CD-ROM, had to retrieve the texts before reading them. No significant main effect was found for multimedia over print or text on screen. However, a significant interaction was found between the use of multimedia and text complexity. Boys were found to cope markedly better with multimedia CD-ROM, a finding which was not expected and ran counter to the results of previous studies

- Abstract
- This article explores the aesthetic design criteria that should be incorporated into the information visualization of a taxonomy intended for use by children. Seven elementary-school students were each asked to represent their ideas in drawings for visualizing a taxonomy. Their drawings were analyzed according to six criteria - balance, equilibrium, symmetry, unity, rhythm, and economy - identified as aesthetic measures in previous research. The drawings revealed the presence of all six measures, and three - unity, equilibrium, and rhythm - were found to play an especially important role. It is therefore concluded that an aesthetic design for an information visualization for young users should incorporate all six measures.

- 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

- Abstract
- The article reports a field study which examined the mental models of 80 undergraduates seeking information for either a history or psychology course essay when they were in an early, exploration stage of researching their essay. This group is presently at a disadvantage when using thesaurus-type schemes in indexes and online search engines because there is a disconnect between how domain novice users of IR systems represent a topic space and how this space is represented in the standard IR system thesaurus. The study attempted to (a) ascertain the coding language used by the 80 undergraduates in the study to mentally represent their topic and then (b) align the mental models with the hierarchical structure found in many thesauri. The intervention focused the undergraduates' thinking about their topic from a topic statement to a thesis statement. The undergraduates were asked to produce three mental model diagrams for their real-life course essay at the beginning, middle, and end of the interview, for a total of 240 mental model diagrams, from which we created a 12-category mental model classification scheme. Findings indicate that at the end of the intervention, (a) the percentage of vertical mental models increased from 24 to 35% of all mental models; but that (b) 3rd-year students had fewer vertical mental models than did 1st-year undergraduates in the study, which is counterintuitive. The results indicate that there is justification for pursuing our research based on the hypothesis that rotating a domain novice's mental model into a vertical position would make it easier for him or her to cognitively connect with the thesaurus's hierarchical representation of the topic area.
