This experiment explored how spatial abilities influence the processes and products of students’ use of dynamic visualizations. General chemistry students with a mix of high and low prior knowledge completed a battery of tests including measures of spatial ability, and an eye-tracking session, in which students viewed three simulated experiments dealing with fluids at the macroscopic and particulate levels of representation.  Before simulations, some participants predicted the outcome at a macroscopic level (N=41) while others did not (N=40). During the simulations, eye movements were tracked to determine what representations the students were viewing. After each simulation, participants explained the outcome of the experiment in both multiple-choice and open-ended formats. Overall, students had difficulty providing particulate-level explanations, and spent more time viewing the macroscopic representation. This was exacerbated after prediction tasks, especially for participants with high spatial abilities.
