Around the world in electrochemistry: a review of the electrochemistry curriculum in high schools

Electrochemistry education of future researchers and citizens is crucial if we are to decarbonise economies and reach targets for net zero. In this paper, we take an overview of electrochemistry within school education. We used curriculum documents obtained from national and state education department websites and from local teachers, examples of assessments and insights from the chemistry education literature to evaluate the extent of electrochemistry education around the world. We found that there is a great deal of electrochemistry included in the intended curriculum for high schools although there is variability depending on how early students are able to specialise in a smaller number of subjects. A range of contexts are used to illustrate the key ideas including galvanic and electrolytic cells, electrolysis and analysis. There is generally constructive alignment between assessment items and the intended curriculum although in some cases assessment was more simplistic than the intended curriculum would suggest. The effectiveness of the taught curriculum is undermined by low teacher confidence in teaching electrochemistry especially more advanced concepts. Additionally, there are a number of misconceptions generated when students learn electrochemistry with some of these potentially arising from published resources such as textbooks.
