Uma proposta de oficina temática remota: ensino de reações de oxirredução contextualizadas com a restauração de obras de arte em metal

Abstract

Oxi-reduction reactions are a content of Chemistry that presents complexity in its learning. Several didactic approaches can be used in their teaching, one of which is the thematic workshop which consists of a pedagogical proposal that facilitates the integration of different areas of knowledge and is able to promote the critical, historical, and social education of students. This work aimed to develop and apply a remote thematic workshop on oxidation-reduction reactions from the context of Conservation - Restoration of metal works of art. Therefore, it was possible to discuss the topic of Chemistry in the phenomenological, theoretical and representational aspects in a contextualized way with Cultural Heritage through Conservation – Restoration. The workshop was applied to second and third grade high school students at a public school. Due to the Covid-19 pandemic, the workshop was held remotely using Information and Communication Technologies (ICTs). The results showed that the content of the oxidation-reduction reactions was well understood and the students perceived the Cultural Heritage as part of the culture's memory, realizing its importance through the relationships between Chemistry, Art and Conservation - Restoration.
