Lewis structures are important for learning chemistry as they serve as an essential link between the structure of chemical compounds and their function. The purpose of this research is to investigate how Lewis structures are represented by students and how these representations change throughout their study of chemistry. By studying students enrolled in general chemistry, organic chemistry, junior/senior-level chemistry courses, graduate-level courses, and chemistry faculty members, we hope to gain a better understanding of when learners begin to make the transition to a more expert-like construction process. To study this transition, we have used OrganicPad - a tablet PC-based structure drawing program - and its Markov modeling capabilities. The results of this use will be presented.
