Electrochemical Polishing of Silverware: A Demonstration of Voltaic and Galvanic Cells  Michelle M. Ivey and Eugene T. Smith
Using a battery and a graphite electrode, an electrolytic cell is constructed to generate a layer of tarnish on silverware. Students then determine that the tarnish can be removed by electrochemically converting it back to silver using aluminum foil and baking soda.

The Effective Use of an Interactive Software Program To Reduce Students' Misconceptions about Batteries  E.-M. Yang, T. J. Greenbowe, and T. Andre
In this study, college students enrolled in an introductory chemistry course were asked a series of open-ended questions about electrochemistry, flashlights, and batteries. Misconceptions were identified, analyzed, and used to develop and test an Interactive Software Program (ISP).

Slide Projector Corrosion Cell  Silvia Tejada, Estela Guevara, and Esperanza Olivares
The process of corrosion can be demonstrated in a slide projector, since the cell is in the shape of a slide, or on the stage of an overhead projector by setting up a simple galvanic cell. Corrosion occurs as the result of a galvanic cell reaction, in which the corroding metal acts as the anode. Several simple demonstrations relating to corrosion are described here.

Students' Misconceptions in Electrochemistry Regarding Current Flow in Electrolyte Solutions and the Salt Bridge  Michael J. Sanger and Thomas J. Greenbowe
Several researchers have documented students' misconceptions in electrochemistry. One reason for the interest in studying electrochemistry is that surveys of students and teachers suggest that students find this topic difficult and research confirms that students' beliefs about problem complexity affect their performance and learning.

Electrode Processes and Aspects Relating to Cell EMF, Current, and Cell Components in Operating Electrochemical Cells: Precollege and College Student Interpretation  N. A. Ogude and J. D. Bradleu
Four areas that present difficulty among high school pupils and tertiary level students in relation to the processes that take place in operating electrochemical cells were identified, including conduction in the electrolyte, electrical neutrality, electrode processes and terminology, and aspects relating to cell emf, current, and cell components. A 20-item questionnaire was designed to determine how widespread misconceptions in these areas were.
