Ensino de química orgânica a partir da temática óleos essenciais no combate ao mosquito Aedes aegypti

Abstract

It is relevant to seek teaching strategies that bring the practice experienced by students to the subjects approached by teachers in the classroom. Thus, we aimed to use the theme of essential oils as natural larvicides alternative against the Aedes aegypti mosquito to review organic chemistry contents in a contextualized way. For this, we realized bibliographic research, an expositive class online, and we used two questionnaires in two courses of Chemistry Teaching Degree in Federal Institute of Piauí campus Cocal. Results showed that despite the theme being widely discussed by the most varied media, 55.55% of students are still confused about diseases and symptoms caused by A. aegypti. We also found that isomerism, organic groups oxygenated identification, and carbon classification in carbonic chains were more complex subjects to the students. Finally, the methodological strategy proposed in this article was approved by 81.81% and 75% of students in both classes, considering it dynamic, pleasant, and attractive. Therefore, this is a valuable alternative to complement traditional expositive classes
