This study investigates the match of technology (iii this case, mode of information presentation) to problem task and the relative importance of each to problem-solving performance. XI: this research, this was achieved by matching information presentation (linear and nonlinear) to problem tasks (spatial and symbolic). The specific focus is on problem-solving performanceinrelationtolinearandnonlinearinformationpresentationandaccess. Italsoexamineswhichcombinationof problem task type arid information presentation yield the best problem-solving performance.
