Keeping an eye on the drawing - Using eye-tracking to analyze the drawing process of resonance tasks

Drawing structural formulas is of great importance in organic chemistry. As such, they serve as an important communication and problem-solving tool. By constructing resonance structures, it is possible, for example, to derive reactivities and structural properties of compounds. Although chemistry education research has emphasized the difficulties that learners encounter concerning the resonance concept, the drawing process of resonance structures has not been examined yet. In this regard, the use of eye-tracking can help to shed light on the drawing process in a process-oriented and detailed manner. Therefore, this paper presents excerpts of a study investigating the drawing process of resonance structures as an example to show the possibilities that the use of eye-tracking offers for analyzing construction processes.
