Chemistry teachers training from the explanation of everyday phenomena: a proposal with results

Abstract

This paper shows the research results obtained with a group of pre-service chemistry teachers at Universidad Pedagógica Nacional, employing didactic units focused in everyday chemistry as strategy for chemistry teaching. The explanations of pre-service chemistry teachers for the analyzed everyday chemical phenomena were characterized according to its admissibility and chemical levels of representation. The project allowed consolidating a space which employs coherently disciplinary and didactic aspects of chemistry, contributing to the pre-service teachers with resources and methodologies to transform the traditional forms of teaching, learning and evaluation of chemistry.
