Abstract
The present work analyzes extracts of 534 speech shifts, recorded in audio and video, of a pedagogical intervention (PI) in the teaching of Chemistry in an ancillary discipline, denominated Experimental Chemistry, for students of the 1st, 2nd and 3rd years of High School, in the Center for Education and Research Applied to Education (CEPAE). The PI focused on the socio-historical construction of Brazil during the Coffee Cycle and the study of Caffeine Extraction of natural products, in a proposal for the implementation of Law 10.639/03 in the Teaching of Chemistry. Our results allow us to say that the students have appropriated the concepts explored in the classroom, demonstrating that it was possible to teach from an epistemically displaced curriculum.
