| Summary: | 碩士 === 國立臺北科技大學 === 互動媒體設計研究所 === 102 === Juveniles are at the bridging stage linking adolescence and adulthood; their experiences and competence to employ information retrieval system in such a period will serve as a foundation for information literacy, which may exert salient influence on their capacities to acquire needed information throughout their lives. Accordingly, research topics concerning approaches to providing teenagers with adequate information, assisting them in interpreting the world with an effective information retrieval system integrating their prior experiences, and further stimulating their imagination have been considered pivotal and essential. Thus, aiming to investigate teenagers’ information-seeking behavior as well as their preferences for a science-related information retrieval system for self-study purposes, this study designed an informational retrieval system and further conducted an experiment in an effort to gain a better understating of teenagers’ reactions to several dissimilar visualized retrieval interfaces.
A mixed methodology—including literature review, in-depth interview, and prototype test—was conducted in this study. In addition, an exploratory factor analysis was administered to abstract potential factors regarding teenagers’ usage of the given information retrieval system. Several major findings were deduced in this study. To begin with, main features of adults’ knowledge structures—complicated, precise, and fixed—are conspicuously different from those of teenagers’—simple, flexible, and diversified. In addition, the four interfaces adopted in this study—Descartes, Tree, Word cloud, and Network-mesh—represented four distinct knowledge maps, and the participants’ preferences were highly-associated with their prior experiences. Last but not least, six potential factors—visual initiation, navigation, controllability, usability, problem-solving, and uncertainty—were abstracted from the factor analysis.
