TITLE:

TEACHING-LEARNIG OF STOCHIOMETRIC CALCULATIONS IN CHEMISTRY: PROBLEMS AND PERSPECTIVES

KEY WORDS:

stoichiometry, teaching-learning, contextualization, dimensional analysis

PAGES: 125
BIG AREA: Ciências Humanas
AREA: Educação
SUMMARY:

The content of Stoichiometric Calculations has long been discussed in the Chemistry discipline. The difficulties presented

by students and, why not, by teachers, related to this content are countless. In this dissertation we address some of these

difficulties, as they are very relevant in the teaching – learning process of Stoichiometric Calculations. The main objectives

were to identify possible variables associated with student learning in relation to this content. To this end, semi-structured

interviews were carried out with ten chemistry teachers from public and private schools in the Distrito Federal. The data

collected, which analyzed using Grounded Data Theory. In addition, six works (books) were also analyzed. One from

each collection suggested for New High School. Due to the complexity of this teaching - learning process, the results

found show that is no way to dissociate the difficulty presented by students, with regard to teaching Stoichiometric

Calculations, without aspects related to teachers, textbooks, teaching methodology of the of this content itself, and even

the students themselves, are not taken into consideration. Therefore, in principle, possible solutions for improving the

teaching and learning of Stoichiometric Calculations must simultaneously take into account the presence of these

aspects.
