Abstract
A previous study of prospective teachers found that students from different countries and different levels of electrochemistry hold common misconceptions, indicating that concepts were presented to them poorly. It also identified new misconceptions by considering electrochemical concepts such as chemical equilibrium, electrochemical equilibrium, and the instrumental requirements for the measurement of cell potential, which had been ignored in the literature. This paper reports how the prospective teachers' scientifically incorrect ideas were used to form assertion-reason-type questions and how these questions were used to identify previously unreported conceptual difficulties related to these ignored concepts. The origins of the learning difficulties were attributed to lack of electrochemical conceptual knowledge and to insufficient explanation of the concepts in the textbooks. The results of this study were consistent with the constructivist model of learning, which suggests that students construct new knowledge through their existing experiences and knowledge, and that some misconceptions may appear to be quite logical to students.

Small-Scale and Low-Cost Electrodes for "Standard" Reduction Potential Measurements
Truls Grønneberg , Per-Odd Eggen and Lise KvittingenJournal of Chemical Education2007 84 (4), 671Small-Scale and Low-Cost Electrodes for "Standard" Reduction Potential Measurements
Truls Grønneberg , Per-Odd Eggen and Lise KvittingenJournal of Chemical Education2007 84 (4), 671This article describes how to construct three simple and inexpensive electrodes: a hydrogen, a chlorine, and a copper electrode. The copper electrode is applied as a reference electrode for the reduction potential measurements and is calibrated against ...
Textbook Error: Short Circuiting an Electrochemical Cell
Judith M. Bonicamp and Roy W. ClarkJournal of Chemical Education2007 84 (4), 731Textbook Error: Short Circuiting an Electrochemical Cell
Judith M. Bonicamp and Roy W. ClarkJournal of Chemical Education2007 84 (4), 731Sometimes errors in electrochemistry discussions are not in the text but in the figures. Many errors in the electrochemical chapters of general chemistry textbooks have been reported previously, yet we found a serious error in the diagrams in eight, 21st ...
