Kranz, David; Schween, Michael; Graulich, Nicole – Chemistry Education Research and Practice, 2023
Reaction mechanisms are a core component of organic chemistry. Being able to handle these mechanisms is a central skill for students in this discipline. Diagnosing and fostering mechanistic reasoning is hence an important branch of chemistry education research. When it comes to reasoning about mechanisms, students often experience difficulties…

Lieber, Leonie; Graulich, Nicole – Chemistry Education Research and Practice, 2022
Building scientific arguments is a central ability for all scientists regardless of their specific domain. In organic chemistry, building arguments is a necessary skill to estimate reaction processes in consideration of the reactivities of reaction centres or the chemical and physical properties. Moreover, building arguments for multiple reaction…

Eckhard, Julia; Rodemer, Marc; Langner, Axel; Bernholt, Sascha; Graulich, Nicole – Chemistry Education Research and Practice, 2022
Research in Organic Chemistry education has revealed students' challenges in mechanistic reasoning. When solving mechanistic tasks, students tend to focus on explicit surface features, apply fragmented conceptual knowledge, rely on rote-memorization and, hence, often struggle to build well-grounded causal explanations. When taking a resource…

Keiner, Liz; Graulich, Nicole – Chemistry Education Research and Practice, 2021
Understanding ongoing chemical processes in the laboratory requires constant shifting between different representational levels--the macroscopic, submicroscopic, and symbolic levels--and analysis of the various mechanistic features of each of these levels. Thus, the ability to explain observations of chemical phenomena with regard to their…

Keiner, Liz; Graulich, Nicole – Chemistry Education Research and Practice, 2020
Chemists refer to chemical phenomena on different representational levels--macroscopic, symbolic, and submicroscopic--which are directly related and connected to each other. Especially in the laboratory, students have to reason about various mechanistic features at the submicroscopic level and connect them in a meaningful way to make sense of the…

Keiner, Liz; Graulich, Nicole; Gottlich, Richard; Pietzner, Verena – Chemistry Education Research and Practice, 2020
Creativity has become an increasingly important competence in today's rapidly changing times. It is a central aspect of social development, but it is hardly discussed in schools and often neglected in the natural sciences. In order to promote creativity in science teaching in a targeted way, it is important to understand the perspectives and views…

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.…

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…
