This study analyzed the eye fixation sequences from students asked to solve stocihiometry problems dealing with particulate nature of matter diagrams. Fixation sequences for each question were grouped using k-means cluster analysis of similarity scores assigned to pairs of fixation sequences. Retrospective think-alouds (RTAs) were then used to identify cognitive processes that students belonging to the same cluster used in combination with visual analysis of the diagrams. Common cognitive processes among students grouped together were then identified through analysis of the RTAs.
