Abstract: We investigated how multimedia presentations of quantitative data affect acquisition, representation, and retention of knowledge about the data. Included in a hypermedia course in human memory, the results of memory experiments were depicted using line graphs. An explanation of the results was presented simultaneously, either visually (text-graph combination) or acoustically (sound-graph combination). To determine the effects of this variation, study times of the results were measured and a variety of comprehension tests and memory tests were administered. We found that the multimedia sound-graph combination was no more effective than the purely visual text-graph combination. In addition, the results indicate that sub?jects did not represent ill memory the appearance of the line graphs but tile meaning of the data depicted by the line graphs.
