Stage supervised: sharing the experiences and the challenges for the chemistry teaching in Coari-Amazonas

Abstract

This research reports the importance of internships and of the project of intervention in the training of teachers, and to this end, it shares experiences in the supervised internships from I to IV carried out at the Alexandre Montoril/Amazonas State School. The challenge of becoming a science teacher in the Amazon region requires from the licensing innovative proposals that overcome the lack of teaching resources, usually not available in schools. Thus, considering the regional peculiarities, an intervention project was carried out from the experience in the internships at the Biology/Chemistry undergraduate that presents as teaching resource natural pigments extracted from typical fruits of the region. The work involved twenty (20) students of the 2nd year of high school and was materialized through the relationship of scientific concepts with the Amazon universe. Among the activities proposed with pigments are four (4) experiments: two (2) of natural indicators, one (1) of chemical breath and one (1) of chromatography. In general, the results of this research show that the aqueous extracts of pigments from the Amazon present themselves as an innovative and strategic educational resource in chemistry classes, because the students previously present cultural knowledge regarding the fruits of the region. In this context, experiments have become "enabling instruments" for the appropriation of scientific concepts, so fundamental to the teaching-learning process.
