Oficina de tinta de terra: contextualizando pigmentos na disciplina de História da Química na LEdoC/UFMA

Abstract

ABSTRACT. In addition to being an environmentally healthy and inexpensive technique, production of land ink can be a facilitator in teaching-learning process in science. This work presents an experience in History of Chemistry, in a course in Licentiate in Rural Education, Federal University of Maranhao (UFMA-Bacabal), in which central theme the chemistry of pigments was worked in a contextualized way. The contextualization of content was carried out through three categories of contextualization process (punctual exemplification and motivational character, teaching-learning strategy, formation of critical citizen in decision-making), culminating in development of a critical-reflective consciousness in CTSA perspective. As methodological procedures were used: expository class; reading and interpretation of scientific articles; debates; land ink office; painting and exposition of ceramic artifacts; and evaluation. In this context, land ink workshop gains featured because it brought scientific, technological and social contexts, contributing to valorization and recovery of facts and experiences of everyday life, discussing and experiencing meaning of sustainability, with technology and technique environmentally healthy and low thus increasing potential of teaching-learning process.
