O ensino de química no curso de secretariado na modalidade EJa do IFG câmpus Jataí: proposta de matereial didático

Abstract

Chemical knowledge is fundamental to understanding the physical and chemical processes that surround us, to promote and monitor technological development and to improve life with quality. However, the formation of truly significant chemical knowledge has been a challenge for educators across the country. Studies indicate that the contextualized teaching through experimental activities related to the learners' daily life has provoked in them a greater interest in participating in the programmed contents. From this perspective, this research was conducted to contribute to the teaching of chemistry with the general objective of proposing a didactic material that takes into account contextualized experimental activities, which can help teachers to deliver the content of oxeduction. In the first part of the work, a bibliographic research on chemistry teaching was done at EJA / PROEJA, observing that most teachers treat this teaching in a traditional way, failing to contextualize it with the learners' daily life, almost always not performing practical activities. The second part of the research consisted precisely in the elaboration of a didactic sequence, based on experimental activities, in order to promote learning by addressing the thematic axis “corrosion”. It was found that the work achieved the proposed objectives. A qualitative assessment showed that students were more participative and interested in studying chemistry. The students' response to the questionnaires also showed that they were really able to understand the proposed contents and are able to relate them to real situations. A quantitative evaluation of the material revealed that 10% of the students were able to average between 6.0 and 6.9, 30% between 7.0 and 8.0 and that 60%, therefore the majority, above 8.0.
