Graulich, Nicole; Hedtrich, Sebastian; Harzenetter, René – Chemistry Education Research and Practice, 2019
Learning to interpret organic structures not as an arrangement of lines and letters but, rather, as a representation of chemical entities is a challenge in organic chemistry. To successfully deal with the variety of molecules or mechanistic representations, a learner needs to understand how a representation depicts domain-specific information.…

Dickmann, Thomas; Opfermann, Maria; Dammann, Elmar; Lang, Martin; Rumann, Stefan – Chemistry Education Research and Practice, 2019
Visualizations and visual models are of substantial importance for science learning (Harrison and Treagust, 2000), and it seems impossible to study chemistry without visualizations. More specifically, the combination of visualizations with text is especially beneficial for learning when dual coding is fostered (Mayer, 2014). However, at the same…

Caspari, I.; Kranz, D.; Graulich, N. – Chemistry Education Research and Practice, 2018
Research in organic chemistry education has revealed that students often rely on rote memorization when learning mechanisms. Not much is known about student productive resources for causal reasoning. To investigate incipient stages of student causal reasoning about single mechanistic steps of organic reactions, we developed a theoretical framework…

Graulich, Nicole; Tiemann, Rudiger; Schreiner, Peter R. – Chemistry Education Research and Practice, 2012
We investigate the efficiency of domain-specific heuristic strategies in mastering and predicting pericyclic six-electron rearrangements. Based on recent research findings on these types of reactions a new concept has been developed that should help students identify and describe six-electron rearrangements more readily in complex molecules. The…
