Prior research has shown that advance organizers in the form of structured interactive overviews alter the learning experi-ence when used as part of a hypertext program, especially when there is a well defined learning goal (Dee-Lucas & Lar-kin, 1995). The effect of the interaction between one's goals and the structure of an overview, as evidenced in the struc-ture of the learner's acquired knowledge base, was explored in the present study. Novices in the domain of biology were assigned to identical hypermedia systems equipped with one of two interactive overviews and to one of two learning goals. Each subject's goal and overview were either consis-tent (e.g., learn about animal families and use an overview organized by animal families) or inconsistent (e.g., learn about animal families and use an overview organized by eco-systems). Cued-association and card sorting posttests were administered to provide measures of conceptual structure. Strong main effects of overview structure were found on both measures. The learners' goals had only a small effect on the shape of conceptual structure and there were no signifi-cant interactions between goal and overview structure on any measure. These results converge on the conclusion that, when the learner has no prior knowledge, the influence of an overview is powerful enough not only to guide the structure of a novice's internal representations, but to overshadow the effect of the learning goal during that process. When learners do have some background information, however, the effect of the overview is significantly reduced. The discussion cen-ters on these theoretical points as well as practical implica-tions of this research.
