O trabalho experimental no ensino de Química

This article deals with conceptions of the experimental work in the Chemistry teaching, developed among teachers and students. The research was carried out using qualitative methodology, based on Gaston Bachelard's thoughts. The results showed dispersion of conceptions among both students and teachers. This dispersion, interpreted as a profile of conceptions, was discussed based on the notions of Bachelard's epistemological profile and Mortimer's conceptual profile. This work points out the need to rethinking and finding new directions for experimental activities in the training courses for Chemistry teachers, in order to meet Chemistry educators' social goals
