Students' Misconceptions in Electrochemistry Regarding Current Flow in Electrolyte Solutions and the Salt Bridge

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. Several articles have promoted pedagogical suggestions or opinions about more effective mehods of teaching electrochemistry; but few, if any, of these have actually been tested.
