| Summary: | literature by developing a framework for the study of lending from decision aid use and by using cognitive load theory to explain the failure of certain decision aid design alternatives to promote learning. Research suggests that appropriate decision aid design is crucial in order to learn from using decision aids (see e.g., Rose and Wolfe 1998; Odom and Dorr 1995; Frederick 1991; Pei and Reneau 1990). This research addresses the issues of lending from decision aids and decision aid design by conducting an experiment that examines the impact of general decision aid design features on the development of knowledge structures by aid users. Specifically, the study focuses on how the cognitive load imposed by the placement of explanations in a decision aid affects the acquisition of schemata by aid users. The study extends prior work by Rose and Wolfe (1998) by considering the roles of general problem-solving ability, problem-solving speed, effort seven key findings from this research: 1) increases ese factors ill the cognitive load produced by a decision aid result in decreased schema acquisition, 2) increases in a decision aid user's effort duration lead to the acquisition of more complex schemata, 3) problem-solving speed is a determinant of effort duration for decision aid users, 4) the general problem-solving ability of an aid user affects the level of schema acquisition that results from aid use, 5) decision aid users with higher ability levels achieve greater improvements in schema acquisition from increased effort duration than users with lower ability levels, 6) the schema acquisition of decision aid users of all ability levels and speeds is affected equally by variations in cognitive load, and 7) cognitive load does not impact the time users spend learning from decision aid use. The findings, when considered together, validate the proposed framework for the future study of learning in decision aid environments. In addition, the results indicate that it is possible to enhance learning through improved decision aid design. |
