Analyzing chunk pauses to measure mathematical competence: Copying equations using 'centre-click' interaction

Mathematical competence can be evaluated by analyzing pauses between strokes that occurring whilst an individual copies equations. These pauses provide a temporal signal that reflects the cognitive effort to process chunks. ‘Centre-click’ interaction with a mouse and response grid on a computer display is introduced as new technique for measuring the temporal chunk signal. Alternative pause measures and forms of normalization are explored. It is shown that centre-click copying can be used to measure mathematical competence.
