Benjamin Pölloth; Dominik Diekemper; Stefan Schwarzer – Chemistry Education Research and Practice, 2023
Recent progress in elucidating chemical reactions allows to explain chemistry by the potential energy of the involved chemical structures. Nevertheless, from an educational point of view, empirical results indicate that students often do not connect the core idea of energy with other chemical concepts. From a resource-oriented perspective,…

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.…

Emden, M.; Weber, K.; Sumfleth, e. – Chemistry Education Research and Practice, 2018
One of the most central tenets of chemistry education is developing an understanding of the processes that involve the Transformation of Matter. Current German curricula postulate content-related abilities ("Kompetenzen") that are expected to be achieved by secondary students when graduating from the lower secondary level at grade 10.…

Rüschenpöhler, Lilith; Markic, Silvija – Chemistry Education Research and Practice, 2020
Research has shown that students' science capital has a large impact on their science aspirations and their development of science identities. In this study, we apply the notion of science capital to chemistry education in order to investigate how students make use of science capital in the field of chemistry. We define chemistry capital as a…

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…

Schwedler, Stefanie; Kaldewey, Marvin – Chemistry Education Research and Practice, 2020
Research in the past decades repeatedly revealed university students' struggles to properly understand physical chemistry concepts. In contrast to school, tertiary teaching relies heavily on the symbolic level, mainly applying abstract representations such as equations and diagrams. To follow the lessons and generate conceptual understanding,…

Schmidt, Hans-Jurgen; Kaufmann, Birgit; Treagust, David F. – Chemistry Education Research and Practice, 2009
In introductory chemistry courses students are presented with the model that matter is composed of particles, and that weak forces of attraction exist between them. This model is used to interpret phenomena such as solubility and melting points, and aids in understanding the changes in states of matter as opposed to chemical reactions. We…
