RAVIOLO, Andrés  and  LERZO, Gabriela. Analogies in teaching stoichiometry: a web pages revision. Rev. electrón. investig. educ. cienc. [online]. 2014, vol.9, n.2, pp.28-41. ISSN 1850-6666.

This paper presents the results of a search of analogies to teach stoichiometry, on web pages. Results are analyzed based on a series of questions posed by the research and suggestions are made for the purpose of teaching. The confusions and the alternative conceptions that these analogies may promote are reviewed, and also the use of images. It's concluded that a teacher will find on the Internet many examples of analogies but few suitable sequences and limited systematized and well-grounded proposals on the matter of Science Education. Work with analogies should specially strengthen that deep understanding of the meaning of chemical equation.
