TITLE:

A METHODOLOGICAL PROPOSAL FOR TEACHING STOICHIOMETRY.

KEY WORDS:

Chemistry teaching; Stoichiometric calculations; Meaningful learning; Didactic sequence

BIG AREA: Ciências Exatas e da Terra
AREA: Química
SUMMARY:

The teaching of Chemistry in high school still faces significant challenges, especially regarding the development of skills for solving stoichiometric calculations. These difficulties are related both to the lack of mastery of basic mathematical operations and to the absence of strategies that promote conceptual understanding and the contextualization of scientific knowledge. This study presents the implementation of a didactic sequence based on the Potentially Significant Teaching Unit (UEPS), aimed at second-year high school students from a public school. The proposal seeks to integrate stoichiometry content with the critical analysis of soft drink labels, fostering connections between science and everyday life. The methodology involves diagnostic activities, guided discussions, problem solving, experimentation, and the construction of concept maps, encouraging the appreciation of prior knowledge and the formation of new cognitive connections. As an expected outcome, in addition to improving student performance, an e-book will be developed for teachers, providing practical guidelines and reflections on the use of UEPS in teaching chemical and stoichiometric calculations.
