Abstract
The conceptualization of physical and dynamic phenomena through functional relationships requires covariational reasoning to grasp the mutual relations between the quantities involved. Additionally, interpreting and explaining these phenomena necessitates engaging with and linking their representations to achieve a
comprehensive understanding. In this contribution, we show how a student engages in covariational reasoning while interpreting and connecting different representations of a physical phenomenon. The methodological tool of eye-tracking was used to collect data on these aspects. The qualitative analysis revealed specific connections between the dynamic object and the graphical representation.
