Resumen:

The purpose of this chapter is to document the pedagogical content knowledge (PCK) of a set of four university chemistry professors teaching stoichiometry, the study of the mass and amount of substance ratios between two or more substances undergoing a chemical change or, in brief, the science of chemical calculations. This topic can be taught with a simple algorithmic purpose going for immediate procedures without much understanding about what to do and/or why one is doing it, or it can be used to reinforce crucial concepts on the chemical reaction or even the particulate constitution of matter. A discussion is presented on the approach given by these four professors in their general chemistry classes, classified as conceptual, representational, contextual, and procedural. Results are conclusive on the various pedagogical foci of three of the approaches (representational, contextual, and procedural), and the equivalence of the four professors' conceptual approach. Results also reveal a link between conceptual and procedural knowledge.
