Teaching organic chemistry: analysis of thematic classes on pesticides in the technical course in agriculture in Ji Paraná.
Organic Chemistry, Thematic Classes, Pesticides.
The research presented in this dissertation sought to understand how the learning of Organic Chemistry is potentiated from the pesticide theme through remote classes, in the pandemic period, verifying if this format significantly favors learning as a teaching methodology. The research had as a sample two classes of the third year of high school, in addition to the materials used by the Chemistry teacher of the technical course in agriculture in the morning and afternoon at EFA (Escola Família Agrícola) Itapirema in the rural area of the municipality of Ji-Paraná, totaling 43 participating students and a teacher. Due to the remote format of the classes that started in March, a Chemistry teacher was chosen, who allowed her to attend her classes and have full access to her materials. Before the thematic classes, the students answered a questionnaire to understand what their initial conceptions about pesticides were and then started the classes approaching the theoretical knowledge of organic chemistry with the proposed theme. In all, there were 24 classes including pesticides to the content through activities aimed at identifying organic functions, structure of compounds, physical-chemical properties and organic nomenclature. It was noticeable that the contents of Organic Chemistry - recognition and classification of organic structures, nomenclature, organic functions and physicochemical properties of compounds - were able to combine with the knowledge of the student's life, so that even the families of the students participated in the activities, mainly due to remote teaching. The results obtained will be presented throughout the dissertation, which presents the results obtained during the execution of thematic classes and how the teaching process took place using the theoretical knowledge associated with the knowledge of the student's daily life, and the way in which the learning process and how this can be verified in the students, through the discussions in the classroom, as well as in comparison with the answers of the initial and final questionnaires. It was found that the approach of scientific concepts through the theme of pesticides favored the process of learning chemistry, since at the beginning the students had misconceptions about the theme, the use of protective equipment and that the thematic classes allowed them to correct such problems. concepts, as well as allowing broad discussions about the indiscriminate use of substances and how they interact with living organisms.
